You can narrow news to a specific version by calling `view-emacs-news'
with a prefix argument or by typing C-u C-h C-n.
* About external Lisp packages
-When you upgrade to Emacs 22 from a previous version, some older
-versions of external Lisp packages are known to behave badly.
-So in general, it is recommended that you upgrade to the latest
-versions of any external Lisp packages that you are using.
-You should also be aware that many Lisp packages have been included
-with Emacs 22 (see the extensive list below), and you should remove
-any older versions of these packages to ensure that the Emacs 22
-version is used. You can use M-x list-load-path-shadows to find such
-older packages.
+* Installation Changes in Emacs 23.1
-Some specific packages that are known to cause problems are:
-** Semantic (used by CEDET, ECB, JDEE): upgrade to latest version.
+* Startup Changes in Emacs 23.1
-** cua.el, cua-mode.el: remove old versions.
+* Incompatible Editing Changes in Emacs 23.1
-* Installation Changes in Emacs 22.1
-** You can build Emacs with Gtk+ widgets by specifying `--with-x-toolkit=gtk'
-when you run configure. This requires Gtk+ 2.4 or newer. This port
-provides a way to display multilingual text in menus (with some caveats).
+* Editing Changes in Emacs 23.1
-** The Emacs Lisp Reference Manual is now part of the distribution.
-The Emacs Lisp Reference Manual in Info format is built as part of the
-Emacs build procedure and installed together with the Emacs User
-Manual. A menu item was added to the menu bar to make it easily
-accessible (Help->More Manuals->Emacs Lisp Reference).
+* New Modes and Packages in Emacs 23.1
-** The Introduction to Programming in Emacs Lisp manual is now part of
-the distribution.
-This manual is now part of the standard distribution and is installed,
-together with the Emacs User Manual, into the Info directory. A menu
-item was added to the menu bar to make it easily accessible
-(Help->More Manuals->Introduction to Emacs Lisp).
+* Changes in Specialized Modes and Packages in Emacs 23.1
-** Leim is now part of the Emacs distribution.
-You no longer need to download a separate tarball in order to build
-Emacs with Leim.
-** Support for MacOS X was added.
-See the files mac/README and mac/INSTALL for build instructions.
+* Changes in Emacs 23.1 on non-free operating systems
-** Mac OS 9 port now uses the Carbon API by default. You can also
-create a non-Carbon build by specifying `NonCarbon' as a target. See
-the files mac/README and mac/INSTALL for build instructions.
-** Support for a Cygwin build of Emacs was added.
+* Incompatible Lisp Changes in Emacs 23.1
-** Support for GNU/Linux systems on X86-64 machines was added.
-** Support for GNU/Linux systems on S390 machines was added.
+* Lisp Changes in Emacs 23.1
-** Support for GNU/Linux systems on Tensilica Xtensa machines was added.
-
-** Support for FreeBSD/Alpha has been added.
-
-** New translations of the Emacs Tutorial are available in the
-following languages: Brasilian Portuguese, Bulgarian, Chinese (both
-with simplified and traditional characters), French, Russian, and
-Italian. Type `C-u C-h t' to choose one of them in case your language
-setup doesn't automatically select the right one.
-
-** New translations of the Emacs reference card are available in the
-Brasilian Portuguese and Russian. The corresponding PostScript files
-are also included.
-
-** A French translation of the `Emacs Survival Guide' is available.
-
-** Emacs now supports new configure options `--program-prefix',
-`--program-suffix' and `--program-transform-name' that affect the names of
-installed programs.
-
-** By default, Emacs now uses a setgid helper program to update game
-scores. The directory ${localstatedir}/games/emacs is the normal
-place for game scores to be stored. You can control this with the
-configure option `--with-game-dir'. The specific user that Emacs uses
-to own the game scores is controlled by `--with-game-user'. If access
-to a game user is not available, then scores will be stored separately
-in each user's home directory.
-
-** Emacs now includes support for loading image libraries on demand.
-(Currently this feature is only used on MS Windows.) You can configure
-the supported image types and their associated dynamic libraries by
-setting the variable `image-library-alist'.
-
-** Emacs can now be built without sound support.
-
-** Emacs Lisp source files are compressed by default if `gzip' is available.
-
-** All images used in Emacs have been consolidated in etc/images and subdirs.
-See also the changes to `find-image', documented below.
-
-** Emacs comes with a new set of icons.
-These icons are displayed on the taskbar and/or titlebar when Emacs
-runs in a graphical environment. Source files for these icons can be
-found in etc/images/icons. (You can't change the icons displayed by
-Emacs by changing these files directly. On X, the icon is compiled
-into the Emacs executable; see gnu.h in the source tree. On MS
-Windows, see nt/icons/emacs.ico.)
-
-** The `emacsserver' program has been removed, replaced with Lisp code.
-
-** The `yow' program has been removed.
-Use the corresponding Emacs feature instead.
-
-** The Emacs terminal emulation in term.el uses a different terminfo name.
-The Emacs terminal emulation in term.el now uses "eterm-color" as its
-terminfo name, since term.el now supports color.
-
-** The script etc/emacs-buffer.gdb can be used with gdb to retrieve the
-contents of buffers from a core dump and save them to files easily, should
-Emacs crash.
-
-** Building with -DENABLE_CHECKING does not automatically build with union
-types any more. Add -DUSE_LISP_UNION_TYPE if you want union types.
-
-** When pure storage overflows while dumping, Emacs now prints how
-much pure storage it will approximately need.
-
-
-* Startup Changes in Emacs 22.1
-
-** Init file changes
-If the init file ~/.emacs does not exist, Emacs will try
-~/.emacs.d/init.el or ~/.emacs.d/init.elc. Likewise, if the shell init file
-~/.emacs_SHELL is not found, Emacs will try ~/.emacs.d/init_SHELL.sh.
-
-** Emacs can now be invoked in full-screen mode on a windowed display.
-When Emacs is invoked on a window system, the new command-line options
-`--fullwidth', `--fullheight', and `--fullscreen' produce a frame
-whose width, height, or both width and height take up the entire
-screen size. (For now, this does not work with some window managers.)
-
-** Emacs now displays a splash screen by default even if command-line
-arguments were given. The new command-line option --no-splash
-disables the splash screen; see also the variable
-`inhibit-splash-screen' (which is also aliased as
-`inhibit-startup-message').
-
-** New user option `inhibit-startup-buffer-menu'.
-When loading many files, for instance with `emacs *', Emacs normally
-displays a buffer menu. This option turns the buffer menu off.
-
-** New command line option -nbc or --no-blinking-cursor disables
-the blinking cursor on graphical terminals.
-
-** The option --script FILE runs Emacs in batch mode and loads FILE.
-It is useful for writing Emacs Lisp shell script files, because they
-can start with this line:
-
- #!/usr/bin/emacs --script
-
-** The -f option, used from the command line to call a function,
-now reads arguments for the function interactively if it is
-an interactively callable function.
-
-** The option --directory DIR now modifies `load-path' immediately.
-Directories are added to the front of `load-path' in the order they
-appear on the command line. For example, with this command line:
-
- emacs -batch -L .. -L /tmp --eval "(require 'foo)"
-
-Emacs looks for library `foo' in the parent directory, then in /tmp, then
-in the other directories in `load-path'. (-L is short for --directory.)
-
-** When you specify a frame size with --geometry, the size applies to
-all frames you create. A position specified with --geometry only
-affects the initial frame.
-
-** Emacs built for MS-Windows now behaves like Emacs on X does,
-with respect to its frame position: if you don't specify a position
-(in your .emacs init file, in the Registry, or with the --geometry
-command-line option), Emacs leaves the frame position to the Windows'
-window manager.
-
-** The command line option --no-windows has been changed to
---no-window-system. The old one still works, but is deprecated.
-
-** If the environment variable DISPLAY specifies an unreachable X display,
-Emacs will now startup as if invoked with the --no-window-system option.
-
-** Emacs now reads the standard abbrevs file ~/.abbrev_defs
-automatically at startup, if it exists. When Emacs offers to save
-modified buffers, it saves the abbrevs too if they have changed. It
-can do this either silently or asking for confirmation first,
-according to the value of `save-abbrevs'.
-
-** New command line option -Q or --quick.
-This is like using -q --no-site-file, but in addition it also disables
-the fancy startup screen.
-
-** New command line option -D or --basic-display.
-Disables the menu-bar, the tool-bar, the scroll-bars, tool tips, and
-the blinking cursor.
-
-** The default is now to use a bitmap as the icon.
-The command-line options --icon-type, -i have been replaced with
-options --no-bitmap-icon, -nbi to turn the bitmap icon off.
-
-** If the environment variable EMAIL is defined, Emacs now uses its value
-to compute the default value of `user-mail-address', in preference to
-concatenation of `user-login-name' with the name of your host machine.
-
-
-* Incompatible Editing Changes in Emacs 22.1
-
-** You can now follow links by clicking Mouse-1 on the link.
-
-See below for more details.
-
-** When the undo information of the current command gets really large
-(beyond the value of `undo-outer-limit'), Emacs discards it and warns
-you about it.
-
-** When Emacs prompts for file names, SPC no longer completes the file name.
-This is so filenames with embedded spaces could be input without the
-need to quote the space with a C-q. The underlying changes in the
-keymaps that are active in the minibuffer are described below under
-"New keymaps for typing file names".
-
-** The completion commands TAB, SPC and ? in the minibuffer apply only
-to the text before point. If there is text in the buffer after point,
-it remains unchanged.
-
-** In incremental search, C-w is changed. M-%, C-M-w and C-M-y are special.
-
-See below under "incremental search changes".
-
-** M-g is now a prefix key.
-M-g g and M-g M-g run goto-line.
-M-g n and M-g M-n run next-error (like C-x `).
-M-g p and M-g M-p run previous-error.
-
-** C-u M-g M-g switches to the most recent previous buffer,
-and goes to the specified line in that buffer.
-
-When goto-line starts to execute, if there's a number in the buffer at
-point then it acts as the default argument for the minibuffer.
-
-** M-o now is the prefix key for setting text properties;
-M-o M-o requests refontification.
-
-** C-x C-f RET (find-file), typing nothing in the minibuffer, is no longer
-a special case.
-
-Since the default input is the current directory, this has the effect
-of specifying the current directory. Normally that means to visit the
-directory with Dired.
-
-You can get the old behavior by typing C-x C-f M-n RET, which fetches
-the actual file name into the minibuffer.
-
-** In Dired's ! command (dired-do-shell-command), `*' and `?' now
-control substitution of the file names only when they are surrounded
-by whitespace. This means you can now use them as shell wildcards
-too. If you want to use just plain `*' as a wildcard, type `*""'; the
-doublequotes make no difference in the shell, but they prevent
-special treatment in `dired-do-shell-command'.
-
-** A prefix argument is no longer required to repeat a jump to a
-previous mark if you set `set-mark-command-repeat-pop' to t. I.e. C-u
-C-SPC C-SPC C-SPC ... cycles through the mark ring. Use C-u C-u C-SPC
-to set the mark immediately after a jump.
-
-** The info-search bindings on C-h C-f, C-h C-k and C-h C-i
-have been moved to C-h F, C-h K and C-h S.
-
-** `apply-macro-to-region-lines' now operates on all lines that begin
-in the region, rather than on all complete lines in the region.
-
-** line-move-ignore-invisible now defaults to t.
-
-** Adaptive filling misfeature removed.
-It no longer treats `NNN.' or `(NNN)' as a prefix.
-
-** The old bindings C-M-delete and C-M-backspace have been deleted,
-since there are situations where one or the other will shut down
-the operating system or your X server.
-
-** The register compatibility key bindings (deprecated since Emacs 19)
-have been removed:
- C-x / point-to-register (Use: C-x r SPC)
- C-x j jump-to-register (Use: C-x r j)
- C-x x copy-to-register (Use: C-x r s)
- C-x g insert-register (Use: C-x r i)
-
-
-* Editing Changes in Emacs 22.1
-
-** The max size of buffers and integers has been doubled.
-On 32bit machines, it is now 256M (i.e. 268435455).
-
-** !MEM FULL! at the start of the mode line indicates that Emacs
-cannot get any more memory for Lisp data. This often means it could
-crash soon if you do things that use more memory. On most systems,
-killing buffers will get out of this state. If killing buffers does
-not make !MEM FULL! disappear, you should save your work and start
-a new Emacs.
-
-** `undo-only' does an undo which does not redo any previous undo.
-
-** Yanking text now discards certain text properties that can
-be inconvenient when you did not expect them. The variable
-`yank-excluded-properties' specifies which ones. Insertion
-of register contents and rectangles also discards these properties.
-
-** New command `kill-whole-line' kills an entire line at once.
-By default, it is bound to C-S-<backspace>.
-
-** M-SPC (just-one-space) when given a numeric argument N
-converts whitespace around point to N spaces.
-
-** You can now switch buffers in a cyclic order with C-x C-left
-(previous-buffer) and C-x C-right (next-buffer). C-x left and
-C-x right can be used as well. The functions keep a different buffer
-cycle for each frame, using the frame-local buffer list.
-
-** C-x 5 C-o displays a specified buffer in another frame
-but does not switch to that frame. It's the multi-frame
-analogue of C-x 4 C-o.
-
-** `special-display-buffer-names' and `special-display-regexps' now
-understand two new boolean pseudo-frame-parameters `same-frame' and
-`same-window'.
-
-** New commands to operate on pairs of open and close characters:
-`insert-pair', `delete-pair', `raise-sexp'.
-
-** M-x setenv now expands environment variable references.
-
-Substrings of the form `$foo' and `${foo}' in the specified new value
-now refer to the value of environment variable foo. To include a `$'
-in the value, use `$$'.
-
-** The default values of paragraph-start and indent-line-function have
-been changed to reflect those used in Text mode rather than those used
-in Paragraph-Indent Text mode.
-
-** The default for the paper size (variable ps-paper-type) is taken
-from the locale.
-
-** Help command changes:
-
-*** Changes in C-h bindings:
-
-C-h e displays the *Messages* buffer.
-
-C-h d runs apropos-documentation.
-
-C-h r visits the Emacs Manual in Info.
-
-C-h followed by a control character is used for displaying files
- that do not change:
-
-C-h C-f displays the FAQ.
-C-h C-e displays the PROBLEMS file.
-
-The info-search bindings on C-h C-f, C-h C-k and C-h C-i
-have been moved to C-h F, C-h K and C-h S.
-
-C-h c, C-h k, C-h w, and C-h f now handle remapped interactive commands.
-- C-h c and C-h k report the actual command (after possible remapping)
- run by the key sequence.
-- C-h w and C-h f on a command which has been remapped now report the
- command it is remapped to, and the keys which can be used to run
- that command.
-
-For example, if C-k is bound to kill-line, and kill-line is remapped
-to new-kill-line, these commands now report:
-- C-h c and C-h k C-k reports:
- C-k runs the command new-kill-line
-- C-h w and C-h f kill-line reports:
- kill-line is remapped to new-kill-line which is on C-k, <deleteline>
-- C-h w and C-h f new-kill-line reports:
- new-kill-line is on C-k
-
-*** The apropos commands now accept a list of words to match.
-When more than one word is specified, at least two of those words must
-be present for an item to match. Regular expression matching is still
-available.
-
-*** The new option `apropos-sort-by-scores' causes the matching items
-to be sorted according to their score. The score for an item is a
-number calculated to indicate how well the item matches the words or
-regular expression that you entered to the apropos command. The best
-match is listed first, and the calculated score is shown for each
-matching item.
-
-*** Help commands `describe-function' and `describe-key' now show function
-arguments in lowercase italics on displays that support it. To change the
-default, customize face `help-argument-name' or redefine the function
-`help-default-arg-highlight'.
-
-*** C-h v and C-h f commands now include a hyperlink to the C source for
-variables and functions defined in C (if the C source is available).
-
-*** Help mode now only makes hyperlinks for faces when the face name is
-preceded or followed by the word `face'. It no longer makes
-hyperlinks for variables without variable documentation, unless
-preceded by one of the words `variable' or `option'. It now makes
-hyperlinks to Info anchors (or nodes) if the anchor (or node) name is
-enclosed in single quotes and preceded by `info anchor' or `Info
-anchor' (in addition to earlier `info node' and `Info node'). In
-addition, it now makes hyperlinks to URLs as well if the URL is
-enclosed in single quotes and preceded by `URL'.
-
-*** The new command `describe-char' (C-u C-x =) pops up a buffer with
-description various information about a character, including its
-encodings and syntax, its text properties, how to input, overlays, and
-widgets at point. You can get more information about some of them, by
-clicking on mouse-sensitive areas or moving there and pressing RET.
-
-*** The command `list-text-properties-at' has been deleted because
-C-u C-x = gives the same information and more.
-
-*** New command `display-local-help' displays any local help at point
-in the echo area. It is bound to `C-h .'. It normally displays the
-same string that would be displayed on mouse-over using the
-`help-echo' property, but, in certain cases, it can display a more
-keyboard oriented alternative.
-
-*** New user option `help-at-pt-display-when-idle' allows to
-automatically show the help provided by `display-local-help' on
-point-over, after suitable idle time. The amount of idle time is
-determined by the user option `help-at-pt-timer-delay' and defaults
-to one second. This feature is turned off by default.
-
-** Mark command changes:
-
-*** A prefix argument is no longer required to repeat a jump to a
-previous mark, i.e. C-u C-SPC C-SPC C-SPC ... cycles through the
-mark ring. Use C-u C-u C-SPC to set the mark immediately after a jump.
-
-*** Marking commands extend the region when invoked multiple times.
-
-If you type C-M-SPC (mark-sexp), M-@ (mark-word), M-h
-(mark-paragraph), or C-M-h (mark-defun) repeatedly, the marked region
-extends each time, so you can mark the next two sexps with M-C-SPC
-M-C-SPC, for example. This feature also works for
-mark-end-of-sentence, if you bind that to a key. It also extends the
-region when the mark is active in Transient Mark mode, regardless of
-the last command. To start a new region with one of marking commands
-in Transient Mark mode, you can deactivate the active region with C-g,
-or set the new mark with C-SPC.
-
-*** Some commands do something special in Transient Mark mode when the
-mark is active--for instance, they limit their operation to the
-region. Even if you don't normally use Transient Mark mode, you might
-want to get this behavior from a particular command. There are two
-ways you can enable Transient Mark mode and activate the mark, for one
-command only.
-
-One method is to type C-SPC C-SPC; this enables Transient Mark mode
-and sets the mark at point. The other method is to type C-u C-x C-x.
-This enables Transient Mark mode temporarily but does not alter the
-mark or the region.
-
-After these commands, Transient Mark mode remains enabled until you
-deactivate the mark. That typically happens when you type a command
-that alters the buffer, but you can also deactivate the mark by typing
-C-g.
-
-*** Movement commands `beginning-of-buffer', `end-of-buffer',
-`beginning-of-defun', `end-of-defun' do not set the mark if the mark
-is already active in Transient Mark mode.
-
-*** M-h (mark-paragraph) now accepts a prefix arg.
-
-With positive arg, M-h marks the current and the following paragraphs;
-if the arg is negative, it marks the current and the preceding
-paragraphs.
-
-** Incremental Search changes:
-
-*** M-% typed in isearch mode invokes `query-replace' or
-`query-replace-regexp' (depending on search mode) with the current
-search string used as the string to replace.
-
-*** C-w in incremental search now grabs either a character or a word,
-making the decision in a heuristic way. This new job is done by the
-command `isearch-yank-word-or-char'. To restore the old behavior,
-bind C-w to `isearch-yank-word' in `isearch-mode-map'.
-
-*** C-y in incremental search now grabs the next line if point is already
-at the end of a line.
-
-*** C-M-w deletes and C-M-y grabs a character in isearch mode.
-Another method to grab a character is to enter the minibuffer by `M-e'
-and to type `C-f' at the end of the search string in the minibuffer.
-
-*** Vertical scrolling is now possible within incremental search.
-To enable this feature, customize the new user option
-`isearch-allow-scroll'. User written commands which satisfy stringent
-constraints can be marked as "scrolling commands". See the Emacs manual
-for details.
-
-*** Isearch no longer adds `isearch-resume' commands to the command
-history by default. To enable this feature, customize the new
-user option `isearch-resume-in-command-history'.
-
-** Replace command changes:
-
-*** When used interactively, the commands `query-replace-regexp' and
-`replace-regexp' allow \,expr to be used in a replacement string,
-where expr is an arbitrary Lisp expression evaluated at replacement
-time. `\#' in a replacement string now refers to the count of
-replacements already made by the replacement command. All regular
-expression replacement commands now allow `\?' in the replacement
-string to specify a position where the replacement string can be
-edited for each replacement. `query-replace-regexp-eval' is now
-deprecated since it offers no additional functionality.
-
-*** query-replace uses isearch lazy highlighting when the new user option
-`query-replace-lazy-highlight' is non-nil.
-
-*** The current match in query-replace is highlighted in new face
-`query-replace' which by default inherits from isearch face.
-
-*** New user option `query-replace-skip-read-only': when non-nil,
-`query-replace' and related functions simply ignore
-a match if part of it has a read-only property.
-
-** Local variables lists:
-
-*** If the local variables list contains any variable-value pairs that
-are not known to be safe, Emacs shows a prompt asking whether to apply
-the local variables list as a whole. In earlier versions, a prompt
-was only issued for variables explicitly marked as risky (for the
-definition of risky variables, see `risky-local-variable-p').
-
-At the prompt, you can choose to save the contents of this local
-variables list to `safe-local-variable-values'. This new customizable
-option is a list of variable-value pairs that are known to be safe.
-Variables can also be marked as safe with the existing
-`safe-local-variable' property (see `safe-local-variable-p').
-However, risky variables will not be added to
-`safe-local-variable-values' in this way.
-
-*** The variable `enable-local-variables' controls how local variable
-lists are handled. t, the default, specifies the standard querying
-behavior. :safe means use only safe values, and ignore the rest.
-:all means set all variables, whether or not they are safe.
-nil means ignore them all. Anything else means always query.
-
-*** The variable `safe-local-eval-forms' specifies a list of forms that
-are ok to evaluate when they appear in an `eval' local variables
-specification. Normally Emacs asks for confirmation before evaluating
-such a form, but if the form appears in this list, no confirmation is
-needed.
-
-*** If a function has a non-nil `safe-local-eval-function' property,
-that means it is ok to evaluate some calls to that function when it
-appears in an `eval' local variables specification. If the property
-is t, then any form calling that function with constant arguments is
-ok. If the property is a function or list of functions, they are called
-with the form as argument, and if any returns t, the form is ok to call.
-
-If the form is not "ok to call", that means Emacs asks for
-confirmation as before.
-
-*** In processing a local variables list, Emacs strips the prefix and
-suffix from every line before processing all the lines.
-
-*** Text properties in local variables.
-
-A file local variables list cannot specify a string with text
-properties--any specified text properties are discarded.
-
-** File operation changes:
-
-*** Unquoted `$' in file names do not signal an error any more when
-the corresponding environment variable does not exist.
-Instead, the `$ENVVAR' text is left as is, so that `$$' quoting
-is only rarely needed.
-
-*** C-x C-f RET, typing nothing in the minibuffer, is no longer a special case.
-
-Since the default input is the current directory, this has the effect
-of specifying the current directory. Normally that means to visit the
-directory with Dired.
-
-*** C-x s (save-some-buffers) now offers an option `d' to diff a buffer
-against its file, so you can see what changes you would be saving.
-
-*** Auto Compression mode is now enabled by default.
-
-*** If the user visits a file larger than `large-file-warning-threshold',
-Emacs asks for confirmation.
-
-*** The commands copy-file, rename-file, make-symbolic-link and
-add-name-to-file, when given a directory as the "new name" argument,
-convert it to a file name by merging in the within-directory part of
-the existing file's name. (This is the same convention that shell
-commands cp, mv, and ln follow.) Thus, M-x copy-file RET ~/foo RET
-/tmp RET copies ~/foo to /tmp/foo.
-
-*** require-final-newline now has two new possible values:
-
-`visit' means add a newline (as an undoable change) if it's needed
-when visiting the file.
-
-`visit-save' means add a newline (as an undoable change) if it's
-needed when visiting the file, and also add a newline if it's needed
-when saving the file.
-
-*** The new option mode-require-final-newline controls how certain
-major modes enable require-final-newline. Any major mode that's
-designed for a kind of file that should normally end in a newline
-sets require-final-newline based on mode-require-final-newline.
-So you can customize mode-require-final-newline to control what these
-modes do.
-
-*** When you are root, and you visit a file whose modes specify
-read-only, the Emacs buffer is now read-only too. Type C-x C-q if you
-want to make the buffer writable. (As root, you can in fact alter the
-file.)
-
-*** find-file-read-only visits multiple files in read-only mode,
-when the file name contains wildcard characters.
-
-*** find-alternate-file replaces the current file with multiple files,
-when the file name contains wildcard characters. It now asks if you
-wish save your changes and not just offer to kill the buffer.
-
-*** When used interactively, `format-write-file' now asks for confirmation
-before overwriting an existing file, unless a prefix argument is
-supplied. This behavior is analogous to `write-file'.
-
-*** The variable `auto-save-file-name-transforms' now has a third element that
-controls whether or not the function `make-auto-save-file-name' will
-attempt to construct a unique auto-save name (e.g. for remote files).
-
-*** The new option `write-region-inhibit-fsync' disables calls to fsync
-in `write-region'. This can be useful on laptops to avoid spinning up
-the hard drive upon each file save. Enabling this variable may result
-in data loss, use with care.
-
-** Minibuffer changes:
-
-*** The completion commands TAB, SPC and ? in the minibuffer apply only
-to the text before point. If there is text in the buffer after point,
-it remains unchanged.
-
-*** The new file-name-shadow-mode is turned ON by default, so that when
-entering a file name, any prefix which Emacs will ignore is dimmed.
-
-*** There's a new face `minibuffer-prompt'.
-Emacs adds this face to the list of text properties stored in the
-variable `minibuffer-prompt-properties', which is used to display the
-prompt string.
-
-*** Enhanced visual feedback in `*Completions*' buffer.
-
-Completions lists use faces to highlight what all completions
-have in common and where they begin to differ.
-
-The common prefix shared by all possible completions uses the face
-`completions-common-part', while the first character that isn't the
-same uses the face `completions-first-difference'. By default,
-`completions-common-part' inherits from `default', and
-`completions-first-difference' inherits from `bold'. The idea of
-`completions-common-part' is that you can use it to make the common
-parts less visible than normal, so that the rest of the differing
-parts is, by contrast, slightly highlighted.
-
-Above fontification is always done when listing completions is
-triggered at minibuffer. If you want to fontify completions whose
-listing is triggered at the other normal buffer, you have to pass
-the common prefix of completions to `display-completion-list' as
-its second argument.
-
-*** File-name completion can now ignore specified directories.
-If an element of the list in `completion-ignored-extensions' ends in a
-slash `/', it indicates a subdirectory that should be ignored when
-completing file names. Elements of `completion-ignored-extensions'
-which do not end in a slash are never considered when a completion
-candidate is a directory.
-
-*** New user option `history-delete-duplicates'.
-If set to t when adding a new history element, all previous identical
-elements are deleted from the history list.
-
-** Redisplay changes:
-
-*** The new face `mode-line-inactive' is used to display the mode line
-of non-selected windows. The `mode-line' face is now used to display
-the mode line of the currently selected window.
-
-The new variable `mode-line-in-non-selected-windows' controls whether
-the `mode-line-inactive' face is used.
-
-*** The mode line position information now comes before the major mode.
-When the file is maintained under version control, that information
-appears between the position information and the major mode.
-
-*** You can now customize the use of window fringes. To control this
-for all frames, use M-x fringe-mode or the Show/Hide submenu of the
-top-level Options menu, or customize the `fringe-mode' variable. To
-control this for a specific frame, use the command M-x
-set-fringe-style.
-
-*** Angle icons in the fringes can indicate the buffer boundaries. In
-addition, up and down arrow bitmaps in the fringe indicate which ways
-the window can be scrolled.
-
-This behavior is activated by setting the buffer-local variable
-`indicate-buffer-boundaries' to a non-nil value. The default value of
-this variable is found in `default-indicate-buffer-boundaries'.
-
-If value is `left' or `right', both angle and arrow bitmaps are
-displayed in the left or right fringe, resp.
-
-The value can also be an alist which specifies the presence and
-position of each bitmap individually.
-
-For example, ((top . left) (t . right)) places the top angle bitmap
-in left fringe, the bottom angle bitmap in right fringe, and both
-arrow bitmaps in right fringe. To show just the angle bitmaps in the
-left fringe, but no arrow bitmaps, use ((top . left) (bottom . left)).
-
-*** On window systems, lines which are exactly as wide as the window
-(not counting the final newline character) are no longer broken into
-two lines on the display (with just the newline on the second line).
-Instead, the newline now "overflows" into the right fringe, and the
-cursor will be displayed in the fringe when positioned on that newline.
-
-The new user option 'overflow-newline-into-fringe' can be set to nil to
-revert to the old behavior of continuing such lines.
-
-*** A window can now have individual fringe and scroll-bar settings,
-in addition to the individual display margin settings.
-
-Such individual settings are now preserved when windows are split
-horizontally or vertically, a saved window configuration is restored,
-or when the frame is resized.
-
-*** When a window has display margin areas, the fringes are now
-displayed between the margins and the buffer's text area, rather than
-outside those margins.
-
-*** New face `escape-glyph' highlights control characters and escape glyphs.
-
-*** Non-breaking space and hyphens are now displayed with a special
-face, either nobreak-space or escape-glyph. You can turn this off or
-specify a different mode by setting the variable `nobreak-char-display'.
-
-*** The parameters of automatic hscrolling can now be customized.
-The variable `hscroll-margin' determines how many columns away from
-the window edge point is allowed to get before automatic hscrolling
-will horizontally scroll the window. The default value is 5.
-
-The variable `hscroll-step' determines how many columns automatic
-hscrolling scrolls the window when point gets too close to the
-window edge. If its value is zero, the default, Emacs scrolls the
-window so as to center point. If its value is an integer, it says how
-many columns to scroll. If the value is a floating-point number, it
-gives the fraction of the window's width to scroll the window.
-
-The variable `automatic-hscrolling' was renamed to
-`auto-hscroll-mode'. The old name is still available as an alias.
-
-*** Moving or scrolling through images (and other lines) taller than
-the window now works sensibly, by automatically adjusting the window's
-vscroll property.
-
-*** Preemptive redisplay now adapts to current load and bandwidth.
-
-To avoid preempting redisplay on fast computers, networks, and displays,
-the arrival of new input is now performed at regular intervals during
-redisplay. The new variable `redisplay-preemption-period' specifies
-the period; the default is to check for input every 0.1 seconds.
-
-*** The %c and %l constructs are now ignored in frame-title-format.
-Due to technical limitations in how Emacs interacts with windowing
-systems, these constructs often failed to render properly, and could
-even cause Emacs to crash.
-
-*** If value of `auto-resize-tool-bars' is `grow-only', the tool bar
-will expand as needed, but not contract automatically. To contract
-the tool bar, you must type C-l.
-
-*** New customize option `overline-margin' controls the space between
-overline and text.
-
-*** New variable `x-underline-at-descent-line' controls the relative
-position of the underline. When set, it overrides the
-`x-use-underline-position-properties' variables.
-
-** New faces:
-
-*** `mode-line-highlight' is the standard face indicating mouse sensitive
-elements on mode-line (and header-line) like `highlight' face on text
-areas.
-
-*** `mode-line-buffer-id' is the standard face for buffer identification
-parts of the mode line.
-
-*** `shadow' face defines the appearance of the "shadowed" text, i.e.
-the text which should be less noticeable than the surrounding text.
-This can be achieved by using shades of grey in contrast with either
-black or white default foreground color. This generic shadow face
-allows customization of the appearance of shadowed text in one place,
-so package-specific faces can inherit from it.
-
-*** `vertical-border' face is used for the vertical divider between windows.
-
-** Font-Lock (syntax highlighting) changes:
-
-*** All modes now support using M-x font-lock-mode to toggle
-fontification, even those such as Occur, Info, and comint-derived
-modes that do their own fontification in a special way.
-
-The variable `Info-fontify' is no longer applicable; to disable
-fontification in Info, remove `turn-on-font-lock' from
-`Info-mode-hook'.
-
-*** New standard font-lock face `font-lock-comment-delimiter-face'.
-
-*** New standard font-lock face `font-lock-preprocessor-face'.
-
-*** Easy to overlook single character negation can now be font-locked.
-You can use the new variable `font-lock-negation-char-face' and the face of
-the same name to customize this. Currently the cc-modes, sh-script-mode,
-cperl-mode and make-mode support this.
-
-*** Font-Lock mode: in major modes such as Lisp mode, where some Emacs
-features assume that an open-paren in column 0 is always outside of
-any string or comment, Font-Lock now highlights any such open-paren in
-bold-red if it is inside a string or a comment, to indicate that it
-can cause trouble. You should rewrite the string or comment so that
-the open-paren is not in column 0.
-
-*** M-o now is the prefix key for setting text properties;
-M-o M-o requests refontification.
-
-*** The default settings for JIT stealth lock parameters are changed.
-The default value for the user option jit-lock-stealth-time is now nil
-instead of 3. This setting of jit-lock-stealth-time disables stealth
-fontification: on today's machines, it may be a bug in font lock
-patterns if fontification otherwise noticeably degrades interactivity.
-If you find movement in infrequently visited buffers sluggish (and the
-major mode maintainer has no better idea), customizing
-jit-lock-stealth-time to a non-nil value will let Emacs fontify
-buffers in the background when it considers the system to be idle.
-jit-lock-stealth-nice is now 0.5 instead of 0.125 which is supposed to
-cause less load than the old defaults.
-
-*** jit-lock can now be delayed with `jit-lock-defer-time'.
-
-If this variable is non-nil, its value should be the amount of Emacs
-idle time in seconds to wait before starting fontification. For
-example, if you set `jit-lock-defer-time' to 0.25, fontification will
-only happen after 0.25s of idle time.
-
-*** contextual refontification is now separate from stealth fontification.
-
-jit-lock-defer-contextually is renamed jit-lock-contextually and
-jit-lock-context-time determines the delay after which contextual
-refontification takes place.
-
-*** lazy-lock is considered obsolete.
-
-The `lazy-lock' package is superseded by `jit-lock' and is considered
-obsolete. `jit-lock' is activated by default; if you wish to continue
-using `lazy-lock', activate it in your ~/.emacs like this:
- (setq font-lock-support-mode 'lazy-lock-mode)
-
-If you invoke `lazy-lock-mode' directly rather than through
-`font-lock-support-mode', it now issues a warning:
- "Use font-lock-support-mode rather than calling lazy-lock-mode"
-
-** Menu support:
-
-*** A menu item "Show/Hide" was added to the top-level menu "Options".
-This menu allows you to turn various display features on and off (such
-as the fringes, the tool bar, the speedbar, and the menu bar itself).
-You can also move the vertical scroll bar to either side here or turn
-it off completely. There is also a menu-item to toggle displaying of
-current date and time, current line and column number in the mode-line.
-
-*** Speedbar has moved from the "Tools" top level menu to "Show/Hide".
-
-*** The menu item "Open File..." has been split into two items, "New File..."
-and "Open File...". "Open File..." now opens only existing files. This is
-to support existing GUI file selection dialogs better.
-
-*** The file selection dialog for Gtk+, Mac, W32 and Motif/LessTif can be
-disabled by customizing the variable `use-file-dialog'.
-
-*** The pop up menus for Lucid now stay up if you do a fast click and can
-be navigated with the arrow keys (like Gtk+, Mac and W32).
-
-*** The menu bar for Motif/LessTif/Lucid/Gtk+ can be navigated with keys.
-Pressing F10 shows the first menu in the menu bar. Navigation is done with
-the arrow keys, select with the return key and cancel with the escape keys.
-
-*** The Lucid menus can display multilingual text in your locale. You have
-to explicitly specify a fontSet resource for this to work, for example
-`-xrm "Emacs*fontSet: -*-helvetica-medium-r-*--*-120-*-*-*-*-*-*,*"'.
-
-*** Dialogs for Lucid/Athena and LessTif/Motif now pop down on pressing
-ESC, like they do for Gtk+, Mac and W32.
-
-*** For the Gtk+ version, you can make Emacs use the old file dialog
-by setting the variable `x-gtk-use-old-file-dialog' to t. Default is to use
-the new dialog.
-
-*** You can exit dialog windows and menus by typing C-g.
-
-** Buffer Menu changes:
-
-*** The new options `buffers-menu-show-directories' and
-`buffers-menu-show-status' let you control how buffers are displayed
-in the menu dropped down when you click "Buffers" from the menu bar.
-
-`buffers-menu-show-directories' controls whether the menu displays
-leading directories as part of the file name visited by the buffer.
-If its value is `unless-uniquify', the default, directories are
-shown unless uniquify-buffer-name-style' is non-nil. The value of nil
-and t turn the display of directories off and on, respectively.
-
-`buffers-menu-show-status' controls whether the Buffers menu includes
-the modified and read-only status of the buffers. By default it is
-t, and the status is shown.
-
-Setting these variables directly does not take effect until next time
-the Buffers menu is regenerated.
-
-*** New command `Buffer-menu-toggle-files-only' toggles display of file
-buffers only in the Buffer Menu. It is bound to T in Buffer Menu
-mode.
-
-*** `buffer-menu' and `list-buffers' now list buffers whose names begin
-with a space, when those buffers are visiting files. Normally buffers
-whose names begin with space are omitted.
-
-** Mouse changes:
-
-*** You can now follow links by clicking Mouse-1 on the link.
-
-Traditionally, Emacs uses a Mouse-1 click to set point and a Mouse-2
-click to follow a link, whereas most other applications use a Mouse-1
-click for both purposes, depending on whether you click outside or
-inside a link. Now the behavior of a Mouse-1 click has been changed
-to match this context-sensitive dual behavior. (If you prefer the old
-behavior, set the user option `mouse-1-click-follows-link' to nil.)
-
-Depending on the current mode, a Mouse-2 click in Emacs can do much
-more than just follow a link, so the new Mouse-1 behavior is only
-activated for modes which explicitly mark a clickable text as a "link"
-(see the new function `mouse-on-link-p' for details). The Lisp
-packages that are included in release 22.1 have been adapted to do
-this, but external packages may not yet support this. However, there
-is no risk in using such packages, as the worst thing that could
-happen is that you get the original Mouse-1 behavior when you click
-on a link, which typically means that you set point where you click.
-
-If you want to get the original Mouse-1 action also inside a link, you
-just need to press the Mouse-1 button a little longer than a normal
-click (i.e. press and hold the Mouse-1 button for half a second before
-you release it).
-
-Dragging the Mouse-1 inside a link still performs the original
-drag-mouse-1 action, typically copy the text.
-
-You can customize the new Mouse-1 behavior via the new user options
-`mouse-1-click-follows-link' and `mouse-1-click-in-non-selected-windows'.
-
-*** If you set the new variable `mouse-autoselect-window' to a non-nil
-value, windows are automatically selected as you move the mouse from
-one Emacs window to another, even within a frame. A minibuffer window
-can be selected only when it is active.
-
-*** On X, when the window manager requires that you click on a frame to
-select it (give it focus), the selected window and cursor position
-normally changes according to the mouse click position. If you set
-the variable x-mouse-click-focus-ignore-position to t, the selected
-window and cursor position do not change when you click on a frame
-to give it focus.
-
-*** Emacs normally highlights mouse sensitive text whenever the mouse
-is over the text. By setting the new variable `mouse-highlight', you
-can optionally enable mouse highlighting only after you move the
-mouse, so that highlighting disappears when you press a key. You can
-also disable mouse highlighting.
-
-*** You can now customize if selecting a region by dragging the mouse
-shall not copy the selected text to the kill-ring by setting the new
-variable mouse-drag-copy-region to nil.
-
-*** Under X, mouse-wheel-mode is turned on by default.
-
-*** Emacs ignores mouse-2 clicks while the mouse wheel is being moved.
-
-People tend to push the mouse wheel (which counts as a mouse-2 click)
-unintentionally while turning the wheel, so these clicks are now
-ignored. You can customize this with the mouse-wheel-click-event and
-mouse-wheel-inhibit-click-time variables.
-
-*** mouse-wheels can now scroll a specific fraction of the window
-(rather than a fixed number of lines) and the scrolling is `progressive'.
-
-** Multilingual Environment (Mule) changes:
-
-*** You can disable character translation for a file using the -*-
-construct. Include `enable-character-translation: nil' inside the
--*-...-*- to disable any character translation that may happen by
-various global and per-coding-system translation tables. You can also
-specify it in a local variable list at the end of the file. For
-shortcut, instead of using this long variable name, you can append the
-character "!" at the end of coding-system name specified in -*-
-construct or in a local variable list. For example, if a file has the
-following header, it is decoded by the coding system `iso-latin-1'
-without any character translation:
-;; -*- coding: iso-latin-1!; -*-
-
-*** Language environment and various default coding systems are setup
-more correctly according to the current locale name. If the locale
-name doesn't specify a charset, the default is what glibc defines.
-This change can result in using the different coding systems as
-default in some locale (e.g. vi_VN).
-
-*** The keyboard-coding-system is now automatically set based on your
-current locale settings if you are not using a window system. This
-can mean that the META key doesn't work but generates non-ASCII
-characters instead, depending on how the terminal (or terminal
-emulator) works. Use `set-keyboard-coding-system' (or customize
-keyboard-coding-system) if you prefer META to work (the old default)
-or if the locale doesn't describe the character set actually generated
-by the keyboard. See Info node `Unibyte Mode'.
-
-*** The new command `set-file-name-coding-system' (C-x RET F) sets
-coding system for encoding and decoding file names. A new menu item
-(Options->Mule->Set Coding Systems->For File Name) invokes this
-command.
-
-*** The new command `revert-buffer-with-coding-system' (C-x RET r)
-revisits the current file using a coding system that you specify.
-
-*** New command `recode-region' decodes the region again by a specified
-coding system.
-
-*** The new command `recode-file-name' changes the encoding of the name
-of a file.
-
-*** New command `ucs-insert' inserts a character specified by its
-unicode.
-
-*** New command quail-show-key shows what key (or key sequence) to type
-in the current input method to input a character at point.
-
-*** Limited support for character `unification' has been added.
-Emacs now knows how to translate between different representations of
-the same characters in various Emacs charsets according to standard
-Unicode mappings. This applies mainly to characters in the ISO 8859
-sets plus some other 8-bit sets, but can be extended. For instance,
-translation works amongst the Emacs ...-iso8859-... charsets and the
-mule-unicode-... ones.
-
-By default this translation happens automatically on encoding.
-Self-inserting characters are translated to make the input conformant
-with the encoding of the buffer in which it's being used, where
-possible.
-
-You can force a more complete unification with the user option
-unify-8859-on-decoding-mode. That maps all the Latin-N character sets
-into Unicode characters (from the latin-iso8859-1 and
-mule-unicode-0100-24ff charsets) on decoding. Note that this mode
-will often effectively clobber data with an iso-2022 encoding.
-
-*** New language environments (set up automatically according to the
-locale): Belarusian, Bulgarian, Chinese-EUC-TW, Croatian, Esperanto,
-French, Georgian, Italian, Latin-7, Latvian, Lithuanian, Malayalam,
-Russian, Russian, Slovenian, Swedish, Tajik, Tamil, UTF-8,Ukrainian,
-Welsh,Latin-6, Windows-1255.
-
-*** New input methods: latin-alt-postfix, latin-postfix, latin-prefix,
-belarusian, bulgarian-bds, bulgarian-phonetic, chinese-sisheng (for
-Chinese Pinyin characters), croatian, dutch, georgian, latvian-keyboard,
-lithuanian-numeric, lithuanian-keyboard, malayalam-inscript, rfc1345,
-russian-computer, sgml, slovenian, tamil-inscript, ukrainian-computer,
-ucs, vietnamese-telex, welsh.
-
-*** There is support for decoding Greek and Cyrillic characters into
-either Unicode (the mule-unicode charsets) or the iso-8859 charsets,
-when possible. The latter are more space-efficient.
- This is controlled by user option utf-fragment-on-decoding.
-
-*** Improved Thai support. A new minor mode `thai-word-mode' (which is
-automatically activated if you select Thai as a language
-environment) changes key bindings of most word-oriented commands to
-versions which recognize Thai words. Affected commands are
- M-f (forward-word)
- M-b (backward-word)
- M-d (kill-word)
- M-DEL (backward-kill-word)
- M-t (transpose-words)
- M-q (fill-paragraph)
-
-*** Indian support has been updated.
-The in-is13194 coding system is now Unicode-based. CDAC fonts are
-assumed. There is a framework for supporting various Indian scripts,
-but currently only Devanagari, Malayalam and Tamil are supported.
-
-*** The utf-8/16 coding systems have been enhanced.
-By default, untranslatable utf-8 sequences are simply composed into
-single quasi-characters. User option `utf-translate-cjk-mode' (it is
-turned on by default) arranges to translate many utf-8 CJK character
-sequences into real Emacs characters in a similar way to the Mule-UCS
-system. As this loads a fairly big data on demand, people who are not
-interested in CJK characters may want to customize it to nil.
-You can augment/amend the CJK translation via hash tables
-`ucs-mule-cjk-to-unicode' and `ucs-unicode-to-mule-cjk'. The utf-8
-coding system now also encodes characters from most of Emacs's
-one-dimensional internal charsets, specifically the ISO-8859 ones.
-The utf-16 coding system is affected similarly.
-
-*** A UTF-7 coding system is available in the library `utf-7'.
-
-*** A new coding system `euc-tw' has been added for traditional Chinese
-in CNS encoding; it accepts both Big 5 and CNS as input; on saving,
-Big 5 is then converted to CNS.
-
-*** Many new coding systems are available in the `code-pages' library.
-These include complete versions of most of those in codepage.el, based
-on Unicode mappings. `codepage-setup' is now obsolete and is used
-only in the MS-DOS port of Emacs. All coding systems defined in
-`code-pages' are auto-loaded.
-
-*** New variable `utf-translate-cjk-unicode-range' controls which
-Unicode characters to translate in `utf-translate-cjk-mode'.
-
-*** iso-10646-1 (`Unicode') fonts can be used to display any range of
-characters encodable by the utf-8 coding system. Just specify the
-fontset appropriately.
-
-** Customize changes:
-
-*** Custom themes are collections of customize options. Create a
-custom theme with M-x customize-create-theme. Use M-x load-theme to
-load and enable a theme, and M-x disable-theme to disable it. Use M-x
-enable-theme to enable a disabled theme.
-
-*** The commands M-x customize-face and M-x customize-face-other-window
-now look at the character after point. If a face or faces are
-specified for that character, the commands by default customize those
-faces.
-
-*** The face-customization widget has been reworked to be less confusing.
-In particular, when you enable a face attribute using the corresponding
-check-box, there's no longer a redundant `*' option in value selection
-for that attribute; the values you can choose are only those which make
-sense for the attribute. When an attribute is de-selected by unchecking
-its check-box, then the (now ignored, but still present temporarily in
-case you re-select the attribute) value is hidden.
-
-*** When you set or reset a variable's value in a Customize buffer,
-the previous value becomes the "backup value" of the variable.
-You can go back to that backup value by selecting "Use Backup Value"
-under the "[State]" button.
-
-** Dired mode:
-
-*** In Dired's ! command (dired-do-shell-command), `*' and `?' now
-control substitution of the file names only when they are surrounded
-by whitespace. This means you can now use them as shell wildcards
-too. If you want to use just plain `*' as a wildcard, type `*""'; the
-double quotes make no difference in the shell, but they prevent
-special treatment in `dired-do-shell-command'.
-
-*** The Dired command `dired-goto-file' is now bound to j, not M-g.
-This is to avoid hiding the global key binding of M-g.
-
-*** New faces dired-header, dired-mark, dired-marked, dired-flagged,
-dired-ignored, dired-directory, dired-symlink, dired-warning
-introduced for Dired mode instead of font-lock faces.
-
-*** New Dired command `dired-compare-directories' marks files
-with different file attributes in two dired buffers.
-
-*** New Dired command `dired-do-touch' (bound to T) changes timestamps
-of marked files with the value entered in the minibuffer.
-
-*** In Dired, the w command now stores the current line's file name
-into the kill ring. With a zero prefix arg, it stores the absolute file name.
-
-*** In Dired-x, Omitting files is now a minor mode, dired-omit-mode.
-
-The mode toggling command is bound to M-o. A new command
-dired-mark-omitted, bound to * O, marks omitted files. The variable
-dired-omit-files-p is obsoleted, use the mode toggling function
-instead.
-
-*** The variables dired-free-space-program and dired-free-space-args
-have been renamed to directory-free-space-program and
-directory-free-space-args, and they now apply whenever Emacs puts a
-directory listing into a buffer.
-
-** Comint changes:
-
-*** The new INSIDE_EMACS environment variable is set to "t" in subshells
-running inside Emacs. This supersedes the EMACS environment variable,
-which will be removed in a future Emacs release. Programs that need
-to know whether they are started inside Emacs should check INSIDE_EMACS
-instead of EMACS.
-
-*** The comint prompt can now be made read-only, using the new user
-option `comint-prompt-read-only'. This is not enabled by default,
-except in IELM buffers. The read-only status of IELM prompts can be
-controlled with the new user option `ielm-prompt-read-only', which
-overrides `comint-prompt-read-only'.
-
-The new commands `comint-kill-whole-line' and `comint-kill-region'
-support editing comint buffers with read-only prompts.
-
-`comint-kill-whole-line' is like `kill-whole-line', but ignores both
-read-only and field properties. Hence, it always kill entire
-lines, including any prompts.
-
-`comint-kill-region' is like `kill-region', except that it ignores
-read-only properties, if it is safe to do so. This means that if any
-part of a prompt is deleted, then the entire prompt must be deleted
-and that all prompts must stay at the beginning of a line. If this is
-not the case, then `comint-kill-region' behaves just like
-`kill-region' if read-only properties are involved: it copies the text
-to the kill-ring, but does not delete it.
-
-*** The new command `comint-insert-previous-argument' in comint-derived
-modes (shell-mode, etc.) inserts arguments from previous command lines,
-like bash's `ESC .' binding. It is bound by default to `C-c .', but
-otherwise behaves quite similarly to the bash version.
-
-*** `comint-use-prompt-regexp-instead-of-fields' has been renamed
-`comint-use-prompt-regexp'. The old name has been kept as an alias,
-but declared obsolete.
-
-** M-x Compile changes:
-
-*** M-x compile has become more robust and reliable
-
-Quite a few more kinds of messages are recognized. Messages that are
-recognized as warnings or informational come in orange or green, instead of
-red. Informational messages are by default skipped with `next-error'
-(controlled by `compilation-skip-threshold').
-
-Location data is collected on the fly as the *compilation* buffer changes.
-This means you could modify messages to make them point to different files.
-This also means you can not go to locations of messages you may have deleted.
-
-The variable `compilation-error-regexp-alist' has now become customizable. If
-you had added your own regexps to this, you'll probably need to include a
-leading `^', otherwise they'll match anywhere on a line. There is now also a
-`compilation-mode-font-lock-keywords' and it nicely handles all the checks
-that configure outputs and -o options so you see at a glance where you are.
-
-The new file etc/compilation.txt gives examples of each type of message.
-
-*** New user option `compilation-environment'.
-This option allows you to specify environment variables for inferior
-compilation processes without affecting the environment that all
-subprocesses inherit.
-
-*** New user option `compilation-disable-input'.
-If this is non-nil, send end-of-file as compilation process input.
-
-*** New options `next-error-highlight' and `next-error-highlight-no-select'
-specify the method of highlighting of the corresponding source line
-in new face `next-error'.
-
-*** A new minor mode `next-error-follow-minor-mode' can be used in
-compilation-mode, grep-mode, occur-mode, and diff-mode (i.e. all the
-modes that can use `next-error'). In this mode, cursor motion in the
-buffer causes automatic display in another window of the corresponding
-matches, compilation errors, etc. This minor mode can be toggled with
-C-c C-f.
-
-*** When the left fringe is displayed, an arrow points to current message in
-the compilation buffer.
-
-*** The new variable `compilation-context-lines' controls lines of leading
-context before the current message. If nil and the left fringe is displayed,
-it doesn't scroll the compilation output window. If there is no left fringe,
-no arrow is displayed and a value of nil means display the message at the top
-of the window.
-
-** Occur mode changes:
-
-*** The new command `multi-occur' is just like `occur', except it can
-search multiple buffers. There is also a new command
-`multi-occur-in-matching-buffers' which allows you to specify the
-buffers to search by their filenames or buffer names. Internally,
-Occur mode has been rewritten, and now uses font-lock, among other
-changes.
-
-*** You can now use next-error (C-x `) and previous-error to advance to
-the next/previous matching line found by M-x occur.
-
-*** In the *Occur* buffer, `o' switches to it in another window, and
-C-o displays the current line's occurrence in another window without
-switching to it.
-
-** Grep changes:
-
-*** Grep has been decoupled from compilation mode setup.
-
-There's a new separate package grep.el, with its own submenu and
-customization group.
-
-*** `grep-find' is now also available under the name `find-grep' where
-people knowing `find-grep-dired' would probably expect it.
-
-*** New commands `lgrep' (local grep) and `rgrep' (recursive grep) are
-more user-friendly versions of `grep' and `grep-find', which prompt
-separately for the regular expression to match, the files to search,
-and the base directory for the search. Case sensitivity of the
-search is controlled by the current value of `case-fold-search'.
-
-These commands build the shell commands based on the new variables
-`grep-template' (lgrep) and `grep-find-template' (rgrep).
-
-The files to search can use aliases defined in `grep-files-aliases'.
-
-Subdirectories listed in `grep-find-ignored-directories' such as those
-typically used by various version control systems, like CVS and arch,
-are automatically skipped by `rgrep'.
-
-*** The grep commands provide highlighting support.
-
-Hits are fontified in green, and hits in binary files in orange. Grep buffers
-can be saved and automatically revisited.
-
-*** New option `grep-highlight-matches' highlights matches in *grep*
-buffer. It uses a special feature of some grep programs which accept
---color option to output markers around matches. When going to the next
-match with `next-error' the exact match is highlighted in the source
-buffer. Otherwise, if `grep-highlight-matches' is nil, the whole
-source line is highlighted.
-
-*** New key bindings in grep output window:
-SPC and DEL scrolls window up and down. C-n and C-p moves to next and
-previous match in the grep window. RET jumps to the source line of
-the current match. `n' and `p' shows next and previous match in
-other window, but does not switch buffer. `{' and `}' jumps to the
-previous or next file in the grep output. TAB also jumps to the next
-file.
-
-*** M-x grep now tries to avoid appending `/dev/null' to the command line
-by using GNU grep `-H' option instead. M-x grep automatically
-detects whether this is possible or not the first time it is invoked.
-When `-H' is used, the grep command line supplied by the user is passed
-unchanged to the system to execute, which allows more complicated
-command lines to be used than was possible before.
-
-*** The new variables `grep-window-height' and `grep-scroll-output' override
-the corresponding compilation mode settings, for grep commands only.
-
-** Cursor display changes:
-
-*** Emacs can produce an underscore-like (horizontal bar) cursor.
-The underscore cursor is set by putting `(cursor-type . hbar)' in
-default-frame-alist. It supports variable heights, like the `bar'
-cursor does.
-
-*** The variable `cursor-in-non-selected-windows' can now be set to any
-of the recognized cursor types.
-
-*** Display of hollow cursors now obeys the buffer-local value (if any)
-of `cursor-in-non-selected-windows' in the buffer that the cursor
-appears in.
-
-*** On text terminals, the variable `visible-cursor' controls whether Emacs
-uses the "very visible" cursor (the default) or the normal cursor.
-
-*** The X resource cursorBlink can be used to turn off cursor blinking.
-
-*** On X, MS Windows, and Mac OS, the blinking cursor's "off" state is
-now controlled by the variable `blink-cursor-alist'.
-
-** X Windows Support:
-
-*** Emacs now supports drag and drop for X. Dropping a file on a window
-opens it, dropping text inserts the text. Dropping a file on a dired
-buffer copies or moves the file to that directory.
-
-*** Under X11, it is possible to swap Alt and Meta (and Super and Hyper).
-The new variables `x-alt-keysym', `x-hyper-keysym', `x-meta-keysym',
-and `x-super-keysym' can be used to choose which keysyms Emacs should
-use for the modifiers. For example, the following two lines swap
-Meta and Alt:
- (setq x-alt-keysym 'meta)
- (setq x-meta-keysym 'alt)
-
-*** The X resource useXIM can be used to turn off use of XIM, which can
-speed up Emacs with slow networking to the X server.
-
-If the configure option `--without-xim' was used to turn off use of
-XIM by default, the X resource useXIM can be used to turn it on.
-
-*** The new variable `x-select-request-type' controls how Emacs
-requests X selection. The default value is nil, which means that
-Emacs requests X selection with types COMPOUND_TEXT and UTF8_STRING,
-and use the more appropriately result.
-
-*** The scrollbar under LessTif or Motif has a smoother drag-scrolling.
-On the other hand, the size of the thumb does not represent the actual
-amount of text shown any more (only a crude approximation of it).
-
-** Xterm support:
-
-*** If you enable Xterm Mouse mode, Emacs will respond to mouse clicks
-on the mode line, header line and display margin, when run in an xterm.
-
-*** Improved key bindings support when running in an xterm.
-When Emacs is running in an xterm more key bindings are available.
-The following should work:
-{C,S,C-S,A}-{right,left,up,down,prior,next,delete,insert,F1-12}.
-These key bindings work on xterm from X.org 6.8 (and later versions),
-they might not work on some older versions of xterm, or on some
-proprietary versions.
-The various keys generated by xterm when the "modifyOtherKeys"
-resource is set are also supported.
-
-** Character terminal color support changes:
-
-*** The new command-line option --color=MODE lets you specify a standard
-mode for a tty color support. It is meant to be used on character
-terminals whose capabilities are not set correctly in the terminal
-database, or with terminal emulators which support colors, but don't
-set the TERM environment variable to a name of a color-capable
-terminal. "emacs --color" uses the same color commands as GNU `ls'
-when invoked with "ls --color", so if your terminal can support colors
-in "ls --color", it will support "emacs --color" as well. See the
-user manual for the possible values of the MODE parameter.
-
-*** Emacs now supports several character terminals which provide more
-than 8 colors. For example, for `xterm', 16-color, 88-color, and
-256-color modes are supported. Emacs automatically notes at startup
-the extended number of colors, and defines the appropriate entries for
-all of these colors.
-
-*** Emacs now uses the full range of available colors for the default
-faces when running on a color terminal, including 16-, 88-, and
-256-color xterms. This means that when you run "emacs -nw" on an
-88-color or 256-color xterm, you will see essentially the same face
-colors as on X.
-
-*** There's a new support for colors on `rxvt' terminal emulator.
-
-** ebnf2ps changes:
-
-*** New option `ebnf-arrow-extra-width' which specify extra width for arrow
-shape drawing.
-The extra width is used to avoid that the arrowhead and the terminal border
-overlap. It depends on `ebnf-arrow-shape' and `ebnf-line-width'.
-
-*** New option `ebnf-arrow-scale' which specify the arrow scale.
-Values lower than 1.0, shrink the arrow.
-Values greater than 1.0, expand the arrow.
-
-* New Modes and Packages in Emacs 22.1
-
-** CUA mode is now part of the Emacs distribution.
-
-The new cua package provides CUA-like keybindings using C-x for
-cut (kill), C-c for copy, C-v for paste (yank), and C-z for undo.
-With cua, the region can be set and extended using shifted movement
-keys (like pc-selection-mode) and typed text replaces the active
-region (like delete-selection-mode). Do not enable these modes with
-cua-mode. Customize the variable `cua-mode' to enable cua.
-
-The cua-selection-mode enables the CUA keybindings for the region but
-does not change the bindings for C-z/C-x/C-c/C-v. It can be used as a
-replacement for pc-selection-mode.
-
-In addition, cua provides unified rectangle support with visible
-rectangle highlighting: Use C-return to start a rectangle, extend it
-using the movement commands (or mouse-3), and cut or copy it using C-x
-or C-c (using C-w and M-w also works).
-
-Use M-o and M-c to `open' or `close' the rectangle, use M-b or M-f, to
-fill it with blanks or another character, use M-u or M-l to upcase or
-downcase the rectangle, use M-i to increment the numbers in the
-rectangle, use M-n to fill the rectangle with a numeric sequence (such
-as 10 20 30...), use M-r to replace a regexp in the rectangle, and use
-M-' or M-/ to restrict command on the rectangle to a subset of the
-rows. See the commentary in cua-base.el for more rectangle commands.
-
-Cua also provides unified support for registers: Use a numeric
-prefix argument between 0 and 9, i.e. M-0 .. M-9, for C-x, C-c, and
-C-v to cut or copy into register 0-9, or paste from register 0-9.
-
-The last text deleted (not killed) is automatically stored in
-register 0. This includes text deleted by typing text.
-
-Finally, cua provides a global mark which is set using S-C-space.
-When the global mark is active, any text which is cut or copied is
-automatically inserted at the global mark position. See the
-commentary in cua-base.el for more global mark related commands.
-
-The features of cua also works with the standard Emacs bindings for
-kill, copy, yank, and undo. If you want to use cua mode, but don't
-want the C-x, C-c, C-v, and C-z bindings, you can customize the
-`cua-enable-cua-keys' variable.
-
-Note: This version of cua mode is not backwards compatible with older
-versions of cua.el and cua-mode.el. To ensure proper operation, you
-must remove older versions of cua.el or cua-mode.el as well as the
-loading and customization of those packages from the .emacs file.
-
-** Tramp is now part of the distribution.
-
-This package is similar to Ange-FTP: it allows you to edit remote
-files. But whereas Ange-FTP uses FTP to access the remote host,
-Tramp uses a shell connection. The shell connection is always used
-for filename completion and directory listings and suchlike, but for
-the actual file transfer, you can choose between the so-called
-`inline' methods (which transfer the files through the shell
-connection using base64 or uu encoding) and the `out-of-band' methods
-(which invoke an external copying program such as `rcp' or `scp' or
-`rsync' to do the copying).
-
-Shell connections can be acquired via `rsh', `ssh', `telnet' and also
-`su' and `sudo'. Ange-FTP is still supported via the `ftp' method.
-
-If you want to disable Tramp you should set
-
- (setq tramp-default-method "ftp")
-
-Removing Tramp, and re-enabling Ange-FTP, can be achieved by M-x
-tramp-unload-tramp.
-
-** The image-dired.el package allows you to easily view, tag and in
-other ways manipulate image files and their thumbnails, using dired as
-the main interface. Image-Dired provides functionality to generate
-simple image galleries.
-
-** Image files are normally visited in Image mode, which lets you toggle
-between viewing the image and viewing the text using C-c C-c.
-
-** The new python.el package is used to edit Python and Jython programs.
-
-** The URL package (which had been part of W3) is now part of Emacs.
-
-** Calc is now part of the Emacs distribution.
-
-Calc is an advanced desk calculator and mathematical tool written in
-Emacs Lisp. The prefix for Calc has been changed to `C-x *' and Calc
-can be started with `C-x * *'. The Calc manual is separate from the
-Emacs manual; within Emacs, type "C-h i m calc RET" to read the
-manual. A reference card is available in `etc/calccard.tex' and
-`etc/calccard.ps'.
-
-** Org mode is now part of the Emacs distribution
-
-Org mode is a mode for keeping notes, maintaining ToDo lists, and
-doing project planning with a fast and effective plain-text system.
-It also contains a plain-text table editor with spreadsheet-like
-capabilities.
-
-The Org mode table editor can be integrated into any major mode by
-activating the minor Orgtbl-mode.
-
-The documentation for org-mode is in a separate manual; within Emacs,
-type "C-h i m org RET" to read that manual. A reference card is
-available in `etc/orgcard.tex' and `etc/orgcard.ps'.
-
-** ERC is now part of the Emacs distribution.
-
-ERC is a powerful, modular, and extensible IRC client for Emacs.
-
-To see what modules are available, type
-M-x customize-option erc-modules RET.
-
-To start an IRC session with ERC, type M-x erc, and follow the prompts
-for server, port, and nick.
-
-** Rcirc is now part of the Emacs distribution.
-
-Rcirc is an Internet relay chat (IRC) client. It supports
-simultaneous connections to multiple IRC servers. Each discussion
-takes place in its own buffer. For each connection you can join
-several channels (many-to-many) and participate in private
-(one-to-one) chats. Both channel and private chats are contained in
-separate buffers.
-
-To start an IRC session using the default parameters, type M-x irc.
-If you type C-u M-x irc, it prompts you for the server, nick, port and
-startup channel parameters before connecting.
-
-** The new package ibuffer provides a powerful, completely
-customizable replacement for buff-menu.el.
-
-** Newsticker is now part of the Emacs distribution.
-
-Newsticker asynchronously retrieves headlines (RSS) from a list of news
-sites, prepares these headlines for reading, and allows for loading the
-corresponding articles in a web browser. Its documentation is in a
-separate manual.
-
-** The wdired.el package allows you to use normal editing commands on Dired
-buffers to change filenames, permissions, etc...
-
-** Ido mode is now part of the Emacs distribution.
-
-The ido (interactively do) package is an extension of the iswitchb
-package to do interactive opening of files and directories in addition
-to interactive buffer switching. Ido is a superset of iswitchb (with
-a few exceptions), so don't enable both packages.
-
-** The new global minor mode `file-name-shadow-mode' modifies the way
-filenames being entered by the user in the minibuffer are displayed, so
-that it's clear when part of the entered filename will be ignored due to
-Emacs' filename parsing rules. The ignored portion can be made dim,
-invisible, or otherwise less visually noticeable. The display method can
-be displayed by customizing the variable `file-name-shadow-properties'.
-
-** Emacs' keyboard macro facilities have been enhanced by the new
-kmacro package.
-
-Keyboard macros are now defined and executed via the F3 and F4 keys:
-F3 starts a macro, F4 ends the macro, and pressing F4 again executes
-the last macro. While defining the macro, F3 inserts a counter value
-which automatically increments every time the macro is executed.
-
-There is now a keyboard macro ring which stores the most recently
-defined macros.
-
-The C-x C-k sequence is now a prefix for the kmacro keymap which
-defines bindings for moving through the keyboard macro ring,
-C-x C-k C-p and C-x C-k C-n, editing the last macro C-x C-k C-e,
-manipulating the macro counter and format via C-x C-k C-c,
-C-x C-k C-a, and C-x C-k C-f. See the commentary in kmacro.el
-for more commands.
-
-The original macro bindings C-x (, C-x ), and C-x e are still
-available, but they now interface to the keyboard macro ring too.
-
-The C-x e command now automatically terminates the current macro
-before calling it, if used while defining a macro.
-
-In addition, when ending or calling a macro with C-x e, the macro can
-be repeated immediately by typing just the `e'. You can customize
-this behavior via the variables kmacro-call-repeat-key and
-kmacro-call-repeat-with-arg.
-
-Keyboard macros can now be debugged and edited interactively.
-C-x C-k SPC steps through the last keyboard macro one key sequence
-at a time, prompting for the actions to take.
-
-** The new keypad setup package provides several common bindings for
-the numeric keypad which is available on most keyboards. The numeric
-keypad typically has the digits 0 to 9, a decimal point, keys marked
-+, -, /, and *, an Enter key, and a NumLock toggle key. The keypad
-package only controls the use of the digit and decimal keys.
-
-By customizing the variables `keypad-setup', `keypad-shifted-setup',
-`keypad-numlock-setup', and `keypad-numlock-shifted-setup', or by
-using the function `keypad-setup', you can rebind all digit keys and
-the decimal key of the keypad in one step for each of the four
-possible combinations of the Shift key state (not pressed/pressed) and
-the NumLock toggle state (off/on).
-
-The choices for the keypad keys in each of the above states are:
-`Plain numeric keypad' where the keys generates plain digits,
-`Numeric keypad with decimal key' where the character produced by the
-decimal key can be customized individually (for internationalization),
-`Numeric Prefix Arg' where the keypad keys produce numeric prefix args
-for Emacs editing commands, `Cursor keys' and `Shifted Cursor keys'
-where the keys work like (shifted) arrow keys, home/end, etc., and
-`Unspecified/User-defined' where the keypad keys (kp-0, kp-1, etc.)
-are left unspecified and can be bound individually through the global
-or local keymaps.
-
-** The printing package is now part of the Emacs distribution.
-
-If you enable the printing package by including (require 'printing) in
-the .emacs file, the normal Print item on the File menu is replaced
-with a Print sub-menu which allows you to preview output through
-ghostview, use ghostscript to print (if you don't have a PostScript
-printer) or send directly to printer a PostScript code generated by
-`ps-print' package. Use M-x pr-help for more information.
-
-** The new package longlines.el provides a minor mode for editing text
-files composed of long lines, based on the `use-hard-newlines'
-mechanism. The long lines are broken up by inserting soft newlines,
-which are automatically removed when saving the file to disk or
-copying into the kill ring, clipboard, etc. By default, Longlines
-mode inserts soft newlines automatically during editing, a behavior
-referred to as "soft word wrap" in other text editors. This is
-similar to Refill mode, but more reliable. To turn the word wrap
-feature off, set `longlines-auto-wrap' to nil.
-
-** SES mode (ses-mode) is a new major mode for creating and editing
-spreadsheet files. Besides the usual Emacs features (intuitive command
-letters, undo, cell formulas in Lisp, plaintext files, etc.) it also offers
-viral immunity and import/export of tab-separated values.
-
-** The new package table.el implements editable, WYSIWYG, embedded
-`text tables' in Emacs buffers. It simulates the effect of putting
-these tables in a special major mode. The package emulates WYSIWYG
-table editing available in modern word processors. The package also
-can generate a table source in typesetting and markup languages such
-as latex and html from the visually laid out text table.
-
-** Filesets are collections of files. You can define a fileset in
-various ways, such as based on a directory tree or based on
-program files that include other program files.
-
-Once you have defined a fileset, you can perform various operations on
-all the files in it, such as visiting them or searching and replacing
-in them.
-
-** The minor mode Reveal mode makes text visible on the fly as you
-move your cursor into hidden regions of the buffer.
-It should work with any package that uses overlays to hide parts
-of a buffer, such as outline-minor-mode, hs-minor-mode, hide-ifdef-mode, ...
-
-There is also Global Reveal mode which affects all buffers.
-
-** New minor mode, Visible mode, toggles invisibility in the current buffer.
-When enabled, it makes all invisible text visible. When disabled, it
-restores the previous value of `buffer-invisibility-spec'.
-
-** The new package flymake.el does on-the-fly syntax checking of program
-source files. See the Flymake's Info manual for more details.
-
-** savehist saves minibuffer histories between sessions.
-To use this feature, turn on savehist-mode in your `.emacs' file.
-
-** The ruler-mode.el library provides a minor mode for displaying an
-"active" ruler in the header line. You can use the mouse to visually
-change the `fill-column', `window-margins' and `tab-stop-list'
-settings.
-
-** The file t-mouse.el is now part of Emacs and provides access to mouse
-events from the console. It still requires gpm to work but has been updated
-for Emacs 22. In particular, the mode-line is now position sensitive.
-
-** The new package scroll-lock.el provides the Scroll Lock minor mode
-for pager-like scrolling. Keys which normally move point by line or
-paragraph will scroll the buffer by the respective amount of lines
-instead and point will be kept vertically fixed relative to window
-boundaries during scrolling.
-
-** The new global minor mode `size-indication-mode' (off by default)
-shows the size of accessible part of the buffer on the mode line.
-
-** The new package conf-mode.el handles thousands of configuration files, with
-varying syntaxes for comments (;, #, //, /* */ or !), assignment (var = value,
-var : value, var value or keyword var value) and sections ([section] or
-section { }). Many files under /etc/, or with suffixes like .cf through
-.config, .properties (Java), .desktop (KDE/Gnome), .ini and many others are
-recognized.
-
-** GDB-Script-mode is used for files like .gdbinit.
-
-** The new package dns-mode.el adds syntax highlighting of DNS master files.
-It is a modern replacement for zone-mode.el, which is now obsolete.
-
-** `cfengine-mode' is a major mode for editing GNU Cfengine
-configuration files.
-
-** The TCL package tcl-mode.el was replaced by tcl.el.
-This was actually done in Emacs-21.1, and was not documented.
-
-* Changes in Specialized Modes and Packages in Emacs 22.1:
-
-** Changes in Dired
-
-*** Bindings for Image-Dired added.
-Several new keybindings, all starting with the C-t prefix, have been
-added to Dired. They are all bound to commands in Image-Dired. As a
-starting point, mark some image files in a dired buffer and do C-t d
-to display thumbnails of them in a separate buffer.
-
-** Info mode changes
-
-*** Images in Info pages are supported.
-
-Info pages show embedded images, in Emacs frames with image support.
-Info documentation that includes images, processed with makeinfo
-version 4.7 or newer, compiles to Info pages with embedded images.
-
-*** `Info-index' offers completion.
-
-*** http and ftp links in Info are now operational: they look like cross
-references and following them calls `browse-url'.
-
-*** isearch in Info uses Info-search and searches through multiple nodes.
-
-Before leaving the initial Info node isearch fails once with the error
-message [initial node], and with subsequent C-s/C-r continues through
-other nodes. When isearch fails for the rest of the manual, it wraps
-around the whole manual to the top/final node. The user option
-`Info-isearch-search' controls whether to use Info-search for isearch,
-or the default isearch search function that wraps around the current
-Info node.
-
-*** New search commands: `Info-search-case-sensitively' (bound to S),
-`Info-search-backward', and `Info-search-next' which repeats the last
-search without prompting for a new search string.
-
-*** New command `info-apropos' searches the indices of the known
-Info files on your system for a string, and builds a menu of the
-possible matches.
-
-*** New command `Info-history-forward' (bound to r and new toolbar icon)
-moves forward in history to the node you returned from after using
-`Info-history-back' (renamed from `Info-last').
-
-*** New command `Info-history' (bound to L) displays a menu of visited nodes.
-
-*** New command `Info-toc' (bound to T) creates a node with table of contents
-from the tree structure of menus of the current Info file.
-
-*** New command `Info-copy-current-node-name' (bound to w) copies
-the current Info node name into the kill ring. With a zero prefix
-arg, puts the node name inside the `info' function call.
-
-*** New face `info-xref-visited' distinguishes visited nodes from unvisited
-and a new option `Info-fontify-visited-nodes' to control this.
-
-*** A numeric prefix argument of `info' selects an Info buffer
-with the number appended to the `*info*' buffer name (e.g. "*info*<2>").
-
-*** Info now hides node names in menus and cross references by default.
-
-If you prefer the old behavior, you can set the new user option
-`Info-hide-note-references' to nil.
-
-*** The default value for `Info-scroll-prefer-subnodes' is now nil.
-
-** Emacs server changes
-
-*** You can have several Emacs servers on the same machine.
-
- % emacs --eval '(setq server-name "foo")' -f server-start &
- % emacs --eval '(setq server-name "bar")' -f server-start &
- % emacsclient -s foo file1
- % emacsclient -s bar file2
-
-*** The `emacsclient' command understands the options `--eval' and
-`--display' which tell Emacs respectively to evaluate the given Lisp
-expression and to use the given display when visiting files.
-
-*** User option `server-mode' can be used to start a server process.
-
-** Locate changes
-
-*** By default, reverting the *Locate* buffer now just runs the last
-`locate' command back over again without offering to update the locate
-database (which normally only works if you have root privileges). If
-you prefer the old behavior, set the new customizable option
-`locate-update-when-revert' to t.
-
-** Desktop package
-
-*** Desktop saving is now a minor mode, `desktop-save-mode'.
-
-*** The variable `desktop-enable' is obsolete.
-
-Customize `desktop-save-mode' to enable desktop saving.
-
-*** Buffers are saved in the desktop file in the same order as that in the
-buffer list.
-
-*** The desktop package can be customized to restore only some buffers
-immediately, remaining buffers are restored lazily (when Emacs is
-idle).
-
-*** New command line option --no-desktop
-
-*** New commands:
- - desktop-revert reverts to the last loaded desktop.
- - desktop-change-dir kills current desktop and loads a new.
- - desktop-save-in-desktop-dir saves desktop in the directory from which
- it was loaded.
- - desktop-lazy-complete runs the desktop load to completion.
- - desktop-lazy-abort aborts lazy loading of the desktop.
-
-*** New customizable variables:
- - desktop-save. Determines whether the desktop should be saved when it is
- killed.
- - desktop-file-name-format. Format in which desktop file names should be
saved.
- - desktop-path. List of directories in which to lookup the desktop file.
- - desktop-locals-to-save. List of local variables to save.
- - desktop-globals-to-clear. List of global variables that `desktop-clear'
will clear.
- - desktop-clear-preserve-buffers-regexp. Regexp identifying buffers that
`desktop-clear'
- should not delete.
- - desktop-restore-eager. Number of buffers to restore immediately. Remaining
buffers are
- restored lazily (when Emacs is idle).
- - desktop-lazy-verbose. Verbose reporting of lazily created buffers.
- - desktop-lazy-idle-delay. Idle delay before starting to create buffers.
-
-*** New hooks:
- - desktop-after-read-hook run after a desktop is loaded.
- - desktop-no-desktop-file-hook run when no desktop file is found.
-
-** Recentf changes
-
-The recent file list is now automatically cleaned up when recentf mode is
-enabled. The new option `recentf-auto-cleanup' controls when to do
-automatic cleanup.
-
-The ten most recent files can be quickly opened by using the shortcut
-keys 1 to 9, and 0, when the recent list is displayed in a buffer via
-the `recentf-open-files', or `recentf-open-more-files' commands.
-
-The `recentf-keep' option replaces `recentf-keep-non-readable-files-p'
-and provides a more general mechanism to customize which file names to
-keep in the recent list.
-
-With the more advanced option `recentf-filename-handlers', you can
-specify functions that successively transform recent file names. For
-example, if set to `file-truename' plus `abbreviate-file-name', the
-same file will not be in the recent list with different symbolic
-links, and the file name will be abbreviated.
-
-To follow naming convention, `recentf-menu-append-commands-flag'
-replaces the misnamed option `recentf-menu-append-commands-p'. The
-old name remains available as alias, but has been marked obsolete.
-
-** Auto-Revert changes
-
-*** You can now use Auto Revert mode to `tail' a file.
-
-If point is at the end of a file buffer before reverting, Auto Revert
-mode keeps it at the end after reverting. Similarly if point is
-displayed at the end of a file buffer in any window, it stays at
-the end of the buffer in that window. This allows to tail a file:
-just put point at the end of the buffer and it stays there. This
-rule applies to file buffers. For non-file buffers, the behavior can
-be mode dependent.
-
-If you are sure that the file will only change by growing at the end,
-then you can tail the file more efficiently by using the new minor
-mode Auto Revert Tail mode. The function `auto-revert-tail-mode'
-toggles this mode.
-
-*** Auto Revert mode is now more careful to avoid excessive reverts and
-other potential problems when deciding which non-file buffers to
-revert. This matters especially if Global Auto Revert mode is enabled
-and `global-auto-revert-non-file-buffers' is non-nil. Auto Revert
-mode only reverts a non-file buffer if the buffer has a non-nil
-`revert-buffer-function' and a non-nil `buffer-stale-function', which
-decides whether the buffer should be reverted. Currently, this means
-that auto reverting works for Dired buffers (although this may not
-work properly on all operating systems) and for the Buffer Menu.
-
-*** If the new user option `auto-revert-check-vc-info' is non-nil, Auto
-Revert mode reliably updates version control info (such as the version
-control number in the mode line), in all version controlled buffers in
-which it is active. If the option is nil, the default, then this info
-only gets updated whenever the buffer gets reverted.
-
-** Changes in Shell Mode
-
-*** Shell output normally scrolls so that the input line is at the
-bottom of the window -- thus showing the maximum possible text. (This
-is similar to the way sequential output to a terminal works.)
-
-** Changes in Hi Lock
-
-*** hi-lock-mode now only affects a single buffer, and a new function
-`global-hi-lock-mode' enables Hi Lock in all buffers. By default, if
-hi-lock-mode is used in what appears to be the initialization file, a
-warning message suggests to use global-hi-lock-mode instead. However,
-if the new variable `hi-lock-archaic-interface-deduce' is non-nil,
-using hi-lock-mode in an initialization file will turn on Hi Lock in all
-buffers and no warning will be issued (for compatibility with the
-behavior in older versions of Emacs).
-
-** Changes in Allout
-
-*** Topic cryptography added, enabling easy gpg topic encryption and
-decryption. Per-topic basis enables interspersing encrypted-text and
-clear-text within a single file to your heart's content, using symmetric
-and/or public key modes. Time-limited key caching, user-provided
-symmetric key hinting and consistency verification, auto-encryption of
-pending topics on save, and more, make it easy to use encryption in
-powerful ways. Encryption behavior customization is collected in the
-allout-encryption customization group.
-
-*** Default command prefix was changed to "\C-c " (control-c space), to
-avoid intruding on user's keybinding space. Customize the
-`allout-command-prefix' variable to your preference.
-
-*** Some previously rough topic-header format edge cases are reconciled.
-Level 1 topics use the mode's comment format, and lines starting with the
-asterisk - for instance, the comment close of some languages (eg, c's "*/"
-or mathematica's "*)") - at the beginning of line are no longer are
-interpreted as level 1 topics in those modes.
-
-*** Many or most commonly occurring "accidental" topics are disqualified.
-Text in item bodies that looks like a low-depth topic is no longer mistaken
-for one unless its first offspring (or that of its next sibling with
-offspring) is only one level deeper.
-
-For example, pasting some text with a bunch of leading asterisks into a
-topic that's followed by a level 3 or deeper topic will not cause the
-pasted text to be mistaken for outline structure.
-
-The same constraint is applied to any level 2 or 3 topics.
-
-This settles an old issue where typed or pasted text needed to be carefully
-reviewed, and sometimes doctored, to avoid accidentally disrupting the
-outline structure. Now that should be generally unnecessary, as the most
-prone-to-occur accidents are disqualified.
-
-*** Allout now refuses to create "containment discontinuities", where a
-topic is shifted deeper than the offspring-depth of its container. On the
-other hand, allout now operates gracefully with existing containment
-discontinuities, revealing excessively contained topics rather than either
-leaving them hidden or raising an error.
-
-*** Navigation within an item is easier. Repeated beginning-of-line and
-end-of-line key commands (usually, ^A and ^E) cycle through the
-beginning/end-of-line and then beginning/end of topic, etc. See new
-customization vars `allout-beginning-of-line-cycles' and
-`allout-end-of-line-cycles'.
-
-*** New or revised allout-mode activity hooks enable creation of
-cooperative enhancements to allout mode without changes to the mode,
-itself.
-
-See `allout-exposure-change-hook', `allout-structure-added-hook',
-`allout-structure-deleted-hook', and `allout-structure-shifted-hook'.
-
-`allout-exposure-change-hook' replaces the existing
-`allout-view-change-hook', which is being deprecated. Both are still
-invoked, but `allout-view-change-hook' will eventually be ignored.
-`allout-exposure-change-hook' is called with explicit arguments detailing
-the specifics of each change (as are the other new hooks), making it easier
-to use than the old version.
-
-There is a new mode deactivation hook, `allout-mode-deactivate-hook', for
-coordinating with deactivation of allout-mode. Both that and the mode
-activation hook, `allout-mode-hook' are now run after the `allout-mode'
-variable is changed, rather than before.
-
-*** Allout now uses text overlay's `invisible' property for concealed text,
-instead of selective-display. This simplifies the code, in particular
-avoiding the need for kludges for isearch dynamic-display, discretionary
-handling of edits of concealed text, undo concerns, etc.
-
-*** There are many other fixes and refinements, including:
-
- - repaired inhibition of inadvertent edits to concealed text, without
- inhibiting undo; we now reveal undo changes within concealed text.
- - auto-fill-mode is now left inactive when allout-mode starts, if it
- already was inactive. also, `allout-inhibit-auto-fill' custom
- configuration variable makes it easy to disable auto fill in allout
- outlines in general or on a per-buffer basis.
- - allout now tolerates fielded text in outlines without disruption.
- - hot-spot navigation now is modularized with a new function,
- `allout-hotspot-key-handler', enabling easier use and enhancement of
- the functionality in allout addons.
- - repaired retention of topic body hanging indent upon topic depth shifts
- - bulleting variation is simpler and more accommodating, both in the
- default behavior and in ability to vary when creating new topics
- - mode deactivation now does cleans up effectively, more properly
- restoring affected variables and hooks to former state, removing
- overlays, etc. see `allout-add-resumptions' and
- `allout-do-resumptions', which replace the old `allout-resumptions'.
- - included a few unit-tests for interior functionality. developers can
- have them automatically run at the end of module load by customizing
- the option `allout-run-unit-tests-on-load'.
- - many, many other, more minor tweaks, fixes, and refinements.
- - version number incremented to 2.2
-
-** Hideshow mode changes
-
-*** New variable `hs-set-up-overlay' allows customization of the overlay
-used to effect hiding for hideshow minor mode. Integration with isearch
-handles the overlay property `display' specially, preserving it during
-temporary overlay showing in the course of an isearch operation.
-
-*** New variable `hs-allow-nesting' non-nil means that hiding a block does
-not discard the hidden state of any "internal" blocks; when the parent
-block is later shown, the internal blocks remain hidden. Default is nil.
-
-** FFAP changes
-
-*** New ffap commands and keybindings:
-
-C-x C-r (`ffap-read-only'),
-C-x C-v (`ffap-alternate-file'), C-x C-d (`ffap-list-directory'),
-C-x 4 r (`ffap-read-only-other-window'), C-x 4 d (`ffap-dired-other-window'),
-C-x 5 r (`ffap-read-only-other-frame'), C-x 5 d (`ffap-dired-other-frame').
-
-*** FFAP accepts wildcards in a file name by default.
-
-C-x C-f passes the file name to `find-file' with non-nil WILDCARDS
-argument, which visits multiple files, and C-x d passes it to `dired'.
-
-** Changes in Skeleton
-
-*** In skeleton.el, `-' marks the `skeleton-point' without interregion
interaction.
-
-`@' has reverted to only setting `skeleton-positions' and no longer
-sets `skeleton-point'. Skeletons which used @ to mark
-`skeleton-point' independent of `_' should now use `-' instead. The
-updated `skeleton-insert' docstring explains these new features along
-with other details of skeleton construction.
-
-*** The variables `skeleton-transformation', `skeleton-filter', and
-`skeleton-pair-filter' have been renamed to
-`skeleton-transformation-function', `skeleton-filter-function', and
-`skeleton-pair-filter-function'. The old names are still available
-as aliases.
-
-** HTML/SGML changes
-
-*** Emacs now tries to set up buffer coding systems for HTML/XML files
-automatically.
-
-*** SGML mode has indentation and supports XML syntax.
-The new variable `sgml-xml-mode' tells SGML mode to use XML syntax.
-When this option is enabled, SGML tags are inserted in XML style,
-i.e., there is always a closing tag.
-By default, its setting is inferred on a buffer-by-buffer basis
-from the file name or buffer contents.
-
-*** The variable `sgml-transformation' has been renamed to
-`sgml-transformation-function'. The old name is still available as
-alias.
-
-*** `xml-mode' is now an alias for `sgml-mode', which has XML support.
-
-** TeX modes
-
-*** New major mode Doctex mode, for *.dtx files.
-
-*** C-c C-c prompts for a command to run, and tries to offer a good default.
-
-*** The user option `tex-start-options-string' has been replaced
-by two new user options: `tex-start-options', which should hold
-command-line options to feed to TeX, and `tex-start-commands' which should hold
-TeX commands to use at startup.
-
-*** verbatim environments are now highlighted in courier by font-lock
-and super/sub-scripts are made into super/sub-scripts.
-
-** RefTeX mode changes
-
-*** Changes to RefTeX's table of contents
-
-The new command keys "<" and ">" in the TOC buffer promote/demote the
-section at point or all sections in the current region, with full
-support for multifile documents.
-
-The new command `reftex-toc-recenter' (`C-c -') shows the current
-section in the TOC buffer without selecting the TOC window.
-Recentering can happen automatically in idle time when the option
-`reftex-auto-recenter-toc' is turned on. The highlight in the TOC
-buffer stays when the focus moves to a different window. A dedicated
-frame can show the TOC with the current section always automatically
-highlighted. The frame is created and deleted from the toc buffer
-with the `d' key.
-
-The toc window can be split off horizontally instead of vertically.
-See new option `reftex-toc-split-windows-horizontally'.
-
-Labels can be renamed globally from the table of contents using the
-key `M-%'.
-
-The new command `reftex-goto-label' jumps directly to a label
-location.
-
-*** Changes related to citations and BibTeX database files
-
-Commands that insert a citation now prompt for optional arguments when
-called with a prefix argument. Related new options are
-`reftex-cite-prompt-optional-args' and `reftex-cite-cleanup-optional-args'.
-
-The new command `reftex-create-bibtex-file' creates a BibTeX database
-with all entries referenced in the current document. The keys "e" and
-"E" allow to produce a BibTeX database file from entries marked in a
-citation selection buffer.
-
-The command `reftex-citation' uses the word in the buffer before the
-cursor as a default search string.
-
-The support for chapterbib has been improved. Different chapters can
-now use BibTeX or an explicit `thebibliography' environment.
-
-The macros which specify the bibliography file (like \bibliography)
-can be configured with the new option `reftex-bibliography-commands'.
-
-Support for jurabib has been added.
-
-*** Global index matched may be verified with a user function.
-
-During global indexing, a user function can verify an index match.
-See new option `reftex-index-verify-function'.
-
-*** Parsing documents with many labels can be sped up.
-
-Operating in a document with thousands of labels can be sped up
-considerably by allowing RefTeX to derive the type of a label directly
-from the label prefix like `eq:' or `fig:'. The option
-`reftex-trust-label-prefix' needs to be configured in order to enable
-this feature. While the speed-up is significant, this may reduce the
-quality of the context offered by RefTeX to describe a label.
-
-*** Miscellaneous changes
-
-The macros which input a file in LaTeX (like \input, \include) can be
-configured in the new option `reftex-include-file-commands'.
-
-RefTeX supports global incremental search.
-
-** BibTeX mode
-
-*** The new command `bibtex-url' browses a URL for the BibTeX entry at
-point (bound to C-c C-l and mouse-2, RET on clickable fields).
-
-*** The new command `bibtex-entry-update' (bound to C-c C-u) updates
-an existing BibTeX entry by inserting fields that may occur but are not
-present.
-
-*** New `bibtex-entry-format' option `required-fields', enabled by default.
-
-*** `bibtex-maintain-sorted-entries' can take values `plain',
-`crossref', and `entry-class' which control the sorting scheme used
-for BibTeX entries. `bibtex-sort-entry-class' controls the sorting
-scheme `entry-class'. TAB completion for reference keys and
-automatic detection of duplicates does not require anymore that
-`bibtex-maintain-sorted-entries' is non-nil.
-
-*** The new command `bibtex-complete' completes word fragment before
-point according to context (bound to M-tab).
-
-*** In BibTeX mode the command `fill-paragraph' (M-q) fills
-individual fields of a BibTeX entry.
-
-*** The new variable `bibtex-autofill-types' contains a list of entry
-types for which fields are filled automatically (if possible).
-
-*** The new commands `bibtex-find-entry' and `bibtex-find-crossref'
-locate entries and crossref'd entries (bound to C-c C-s and C-c C-x).
-Crossref fields are clickable (bound to mouse-2, RET).
-
-*** The new variables `bibtex-files' and `bibtex-file-path' define a set
-of BibTeX files that are searched for entry keys.
-
-*** The new command `bibtex-validate-globally' checks for duplicate keys
-in multiple BibTeX files.
-
-*** If the new variable `bibtex-autoadd-commas' is non-nil,
-automatically add missing commas at end of BibTeX fields.
-
-*** The new command `bibtex-copy-summary-as-kill' pushes summary
-of BibTeX entry to kill ring (bound to C-c C-t).
-
-*** If the new variable `bibtex-parse-keys-fast' is non-nil,
-use fast but simplified algorithm for parsing BibTeX keys.
-
-*** The new variables bibtex-expand-strings and
-bibtex-autokey-expand-strings control the expansion of strings when
-extracting the content of a BibTeX field.
-
-*** The variables `bibtex-autokey-name-case-convert' and
-`bibtex-autokey-titleword-case-convert' have been renamed to
-`bibtex-autokey-name-case-convert-function' and
-`bibtex-autokey-titleword-case-convert-function'. The old names are
-still available as aliases.
-
-** GUD changes
-
-*** The new package gdb-ui.el provides an enhanced graphical interface to
-GDB. You can interact with GDB through the GUD buffer in the usual way, but
-there are also further buffers which control the execution and describe the
-state of your program. It can separate the input/output of your program from
-that of GDB and watches expressions in the speedbar. It also uses features of
-Emacs 21/22 such as the toolbar, and bitmaps in the fringe to indicate
-breakpoints.
-
-To use this package just type M-x gdb. See the Emacs manual if you want the
-old behaviour.
-
-*** GUD mode has its own tool bar for controlling execution of the inferior
-and other common debugger commands.
-
-*** In GUD mode, when talking to GDB, C-x C-a C-j "jumps" the program
-counter to the specified source line (the one where point is).
-
-*** The variable tooltip-gud-tips-p has been removed. GUD tooltips can now be
-toggled independently of normal tooltips with the minor mode
-`gud-tooltip-mode'.
-
-*** In graphical mode, with a C program, GUD Tooltips have been extended to
-display the #define directive associated with an identifier when program is
-not executing.
-
-*** GUD mode improvements for jdb:
-
-**** Search for source files using jdb classpath and class information.
-Fast startup since there is no need to scan all source files up front.
-There is also no need to create and maintain lists of source
-directories to scan. Look at `gud-jdb-use-classpath' and
-`gud-jdb-classpath' customization variables documentation.
-
-**** The previous method of searching for source files has been
-preserved in case someone still wants/needs to use it.
-Set `gud-jdb-use-classpath' to nil.
-
-**** Supports the standard breakpoint (gud-break, gud-clear)
-set/clear operations from Java source files under the classpath, stack
-traversal (gud-up, gud-down), and run until current stack finish
-(gud-finish).
-
-**** Supports new jdb (Java 1.2 and later) in addition to oldjdb
-(Java 1.1 jdb).
-
-*** Added jdb Customization Variables
-
-**** `gud-jdb-command-name'. What command line to use to invoke jdb.
-
-**** `gud-jdb-use-classpath'. Allows selection of java source file searching
-method: set to t for new method, nil to scan `gud-jdb-directories' for
-java sources (previous method).
-
-**** `gud-jdb-directories'. List of directories to scan and search for Java
-classes using the original gud-jdb method (if `gud-jdb-use-classpath'
-is nil).
-
-*** Minor Improvements
-
-**** The STARTTLS wrapper (starttls.el) can now use GNUTLS
-instead of the OpenSSL based `starttls' tool. For backwards
-compatibility, it prefers `starttls', but you can toggle
-`starttls-use-gnutls' to switch to GNUTLS (or simply remove the
-`starttls' tool).
-
-**** Do not allow debugger output history variable to grow without bounds.
-
-** Lisp mode changes
-
-*** Lisp mode now uses `font-lock-doc-face' for doc strings.
-
-*** C-u C-M-q in Emacs Lisp mode pretty-prints the list after point.
-
-*** New features in evaluation commands
-
-**** The function `eval-defun' (C-M-x) called on defface reinitializes
-the face to the value specified in the defface expression.
-
-**** Typing C-x C-e twice prints the value of the integer result
-in additional formats (octal, hexadecimal, character) specified
-by the new function `eval-expression-print-format'. The same
-function also defines the result format for `eval-expression' (M-:),
-`eval-print-last-sexp' (C-j) and some edebug evaluation functions.
-
-** Changes to cmuscheme
-
-*** Emacs now offers to start Scheme if the user tries to
-evaluate a Scheme expression but no Scheme subprocess is running.
-
-*** If the file ~/.emacs_NAME or ~/.emacs.d/init_NAME.scm (where NAME
-is the name of the Scheme interpreter) exists, its contents are sent
-to the Scheme subprocess upon startup.
-
-*** There are new commands to instruct the Scheme interpreter to trace
-procedure calls (`scheme-trace-procedure') and to expand syntactic forms
-(`scheme-expand-current-form'). The commands actually sent to the Scheme
-subprocess are controlled by the user options `scheme-trace-command',
-`scheme-untrace-command' and `scheme-expand-current-form'.
-
-** Ewoc changes
-
-*** The new function `ewoc-delete' deletes specified nodes.
-
-*** `ewoc-create' now takes optional arg NOSEP, which inhibits insertion of
-a newline after each pretty-printed entry and after the header and footer.
-This allows you to create multiple-entry ewocs on a single line and to
-effect "invisible" nodes by arranging for the pretty-printer to not print
-anything for those nodes.
-
-For example, these two sequences of expressions behave identically:
-
-;; NOSEP nil

-** CC mode changes
-
-*** The CC Mode manual has been extensively revised.
-The information about using CC Mode has been separated from the larger
-and more difficult chapters about configuration.
-
-*** New Minor Modes
-**** Electric Minor Mode toggles the electric action of non-alphabetic keys.
-The new command c-toggle-electric-mode is bound to C-c C-l. Turning the
-mode off can be helpful for editing chaotically indented code and for
-users new to CC Mode, who sometimes find electric indentation
-disconcerting. Its current state is displayed in the mode line with an
-'l', e.g. "C/al".
-
-**** Subword Minor Mode makes Emacs recognize word boundaries at upper case
-letters in StudlyCapsIdentifiers. You enable this feature by C-c C-w. It can
-also be used in non-CC Mode buffers. :-) Contributed by Masatake YAMATO.
-
-*** Support for the AWK language.
-Support for the AWK language has been introduced. The implementation is
-based around GNU AWK version 3.1, but it should work pretty well with
-any AWK. As yet, not all features of CC Mode have been adapted for AWK.
-Here is a summary:
-
-**** Indentation Engine
-The CC Mode indentation engine fully supports AWK mode.
-
-AWK mode handles code formatted in the conventional AWK fashion: `{'s
-which start actions, user-defined functions, or compound statements are
-placed on the same line as the associated construct; the matching `}'s
-are normally placed under the start of the respective pattern, function
-definition, or structured statement.
-
-The predefined line-up functions haven't yet been adapted for AWK
-mode, though some of them may work serendipitously. There shouldn't
-be any problems writing custom indentation functions for AWK mode.
-
-**** Font Locking
-There is a single level of font locking in AWK mode, rather than the
-three distinct levels the other modes have. There are several
-idiosyncrasies in AWK mode's font-locking due to the peculiarities of
-the AWK language itself.
-
-**** Comment and Movement Commands
-These commands all work for AWK buffers. The notion of "defun" has
-been augmented to include AWK pattern-action pairs - the standard
-"defun" commands on key sequences C-M-a, C-M-e, and C-M-h use this
-extended definition.
-
-**** "awk" style, Auto-newline Insertion and Clean-ups
-A new style, "awk" has been introduced, and this is now the default
-style for AWK code. With auto-newline enabled, the clean-up
-c-one-liner-defun (see above) is useful.
-
-*** Font lock support.
-CC Mode now provides font lock support for all its languages. This
-supersedes the font lock patterns that have been in the core font lock
-package for C, C++, Java and Objective-C. Like indentation, font
-locking is done in a uniform way across all languages (except the new
-AWK mode - see below). That means that the new font locking will be
-different from the old patterns in various details for most languages.
-
-The main goal of the font locking in CC Mode is accuracy, to provide a
-dependable aid in recognizing the various constructs. Some, like
-strings and comments, are easy to recognize while others like
-declarations and types can be very tricky. CC Mode can go to great
-lengths to recognize declarations and casts correctly, especially when
-the types aren't recognized by standard patterns. This is a fairly
-demanding analysis which can be slow on older hardware, and it can
-therefore be disabled by choosing a lower decoration level with the
-variable font-lock-maximum-decoration.
-
-Note that the most demanding font lock level has been tuned with lazy
-fontification in mind; Just-In-Time-Lock mode should be enabled for
-the highest font lock level (by default, it is). Fontifying a file
-with several thousand lines in one go can take the better part of a
-minute.
-
-**** The (c|c++|objc|java|idl|pike)-font-lock-extra-types variables
-are now used by CC Mode to recognize identifiers that are certain to
-be types. (They are also used in cases that aren't related to font
-locking.) At the maximum decoration level, types are often recognized
-properly anyway, so these variables should be fairly restrictive and
-not contain patterns for uncertain types.
-
-**** Support for documentation comments.
-There is a "plugin" system to fontify documentation comments like
-Javadoc and the markup within them. It's independent of the host
-language, so it's possible to e.g. turn on Javadoc font locking in C
-buffers. See the variable c-doc-comment-style for details.
-
-Currently three kinds of doc comment styles are recognized: Sun's
-Javadoc, Autodoc (which is used in Pike) and GtkDoc (used in C). (The
-last was contributed by Masatake YAMATO). This is by no means a
-complete list of the most common tools; if your doc comment extractor
-of choice is missing then please drop a note to address@hidden
-
-**** Better handling of C++ templates.
-As a side effect of the more accurate font locking, C++ templates are
-now handled much better. The angle brackets that delimit them are
-given parenthesis syntax so that they can be navigated like other
-parens.
-
-This also improves indentation of templates, although there still is
-work to be done in that area. E.g. it's required that multiline
-template clauses are written in full and then refontified to be
-recognized, and the indentation of nested templates is a bit odd and
-not as configurable as it ought to be.
-
-**** Improved handling of Objective-C and CORBA IDL.
-Especially the support for Objective-C and IDL has gotten an overhaul.
-The special "@" declarations in Objective-C are handled correctly.
-All the keywords used in CORBA IDL, PSDL, and CIDL are recognized and
-handled correctly, also wrt indentation.
-
-*** Changes in Key Sequences
-**** c-toggle-auto-hungry-state is no longer bound to C-c C-t.
-
-**** c-toggle-hungry-state is no longer bound to C-c C-d.
-This binding has been taken over by c-hungry-delete-forwards.
-
-**** c-toggle-auto-state (C-c C-t) has been renamed to c-toggle-auto-newline.
-c-toggle-auto-state remains as an alias.
-
-**** The new commands c-hungry-backspace and c-hungry-delete-forwards
-have key bindings C-c C-DEL (or C-c DEL, for the benefit of TTYs) and
-C-c C-d (or C-c C-<delete> or C-c <delete>) respectively. These
-commands delete entire blocks of whitespace with a single
-key-sequence. [N.B. "DEL" is the <backspace> key.]
-
-**** The new command c-toggle-electric-mode is bound to C-c C-l.
-
-**** The new command c-subword-mode is bound to C-c C-w.
-
-*** C-c C-s (`c-show-syntactic-information') now highlights the anchor
-position(s).
-
-*** New syntactic symbols in IDL mode.
-The top level constructs "module" and "composition" (from CIDL) are
-now handled like "namespace" in C++: They are given syntactic symbols
-module-open, module-close, inmodule, composition-open,
-composition-close, and incomposition.
-
-*** New functions to do hungry delete without enabling hungry delete mode.
-The new functions `c-hungry-backspace' and `c-hungry-delete-forward'
-provide hungry deletion without having to toggle a mode. They are
-bound to C-c C-DEL and C-c C-d (and several variants, for the benefit
-of different keyboard setups. See "Changes in key sequences" above).
-
-*** Better control over `require-final-newline'.
-
-The variable `c-require-final-newline' specifies which of the modes
-implemented by CC mode should insert final newlines. Its value is a
-list of modes, and only those modes should do it. By default the list
-includes C, C++ and Objective-C modes.
-
-Whichever modes are in this list will set `require-final-newline'
-based on `mode-require-final-newline'.
-
-*** Format change for syntactic context elements.
-
-The elements in the syntactic context returned by `c-guess-basic-syntax'
-and stored in `c-syntactic-context' has been changed somewhat to allow
-attaching more information. They are now lists instead of single cons
-cells. E.g. a line that previously had the syntactic analysis
-
-((inclass . 11) (topmost-intro . 13))
-
-is now analyzed as
-
-((inclass 11) (topmost-intro 13))
-
-In some cases there are more than one position given for a syntactic
-symbol.
-
-This change might affect code that calls `c-guess-basic-syntax'
-directly, and custom lineup functions if they use
-`c-syntactic-context'. However, the argument given to lineup
-functions is still a single cons cell with nil or an integer in the
-cdr.
-
-*** API changes for derived modes.
-
-There have been extensive changes "under the hood" which can affect
-derived mode writers. Some of these changes are likely to cause
-incompatibilities with existing derived modes, but on the other hand
-care has now been taken to make it possible to extend and modify CC
-Mode with less risk of such problems in the future.
-
-**** New language variable system.
-These are variables whose values vary between CC Mode's different
-languages. See the comment blurb near the top of cc-langs.el.
-
-**** New initialization functions.
-The initialization procedure has been split up into more functions to
-give better control: `c-basic-common-init', `c-font-lock-init', and
-`c-init-language-vars'.
-
-*** Changes in analysis of nested syntactic constructs.
-The syntactic analysis engine has better handling of cases where
-several syntactic constructs appear nested on the same line. They are
-now handled as if each construct started on a line of its own.
-
-This means that CC Mode now indents some cases differently, and
-although it's more consistent there might be cases where the old way
-gave results that's more to one's liking. So if you find a situation
-where you think that the indentation has become worse, please report
-it to address@hidden
-
-**** New syntactic symbol substatement-label.
-This symbol is used when a label is inserted between a statement and
-its substatement. E.g:
-
- if (x)
- x_is_true:
- do_stuff();
-
-*** Better handling of multiline macros.
-
-**** Syntactic indentation inside macros.
-The contents of multiline #define's are now analyzed and indented
-syntactically just like other code. This can be disabled by the new
-variable `c-syntactic-indentation-in-macros'. A new syntactic symbol
-`cpp-define-intro' has been added to control the initial indentation
-inside `#define's.
-
-**** New lineup function `c-lineup-cpp-define'.
-
-Now used by default to line up macro continuation lines. The behavior
-of this function closely mimics the indentation one gets if the macro
-is indented while the line continuation backslashes are temporarily
-removed. If syntactic indentation in macros is turned off, it works
-much line `c-lineup-dont-change', which was used earlier, but handles
-empty lines within the macro better.
-
-**** Automatically inserted newlines continues the macro if used within one.
-This applies to the newlines inserted by the auto-newline mode, and to
-`c-context-line-break' and `c-context-open-line'.
-
-**** Better alignment of line continuation backslashes.
-`c-backslash-region' tries to adapt to surrounding backslashes. New
-variable `c-backslash-max-column' puts a limit on how far out
-backslashes can be moved.
-
-**** Automatic alignment of line continuation backslashes.
-This is controlled by the new variable `c-auto-align-backslashes'. It
-affects `c-context-line-break', `c-context-open-line' and newlines
-inserted in Auto-Newline mode.
-
-**** Line indentation works better inside macros.
-Regardless whether syntactic indentation and syntactic indentation
-inside macros are enabled or not, line indentation now ignores the
-line continuation backslashes. This is most noticeable when syntactic
-indentation is turned off and there are empty lines (save for the
-backslash) in the macro.
-
-*** indent-for-comment is more customizable.
-The behavior of M-; (indent-for-comment) is now configurable through
-the variable `c-indent-comment-alist'. The indentation behavior is
-based on the preceding code on the line, e.g. to get two spaces after
-#else and #endif but indentation to `comment-column' in most other
-cases (something which was hardcoded earlier).
-
-*** New function `c-context-open-line'.
-It's the open-line equivalent of `c-context-line-break'.
-
-*** New clean-ups
-
-**** `comment-close-slash'.
-With this clean-up, a block (i.e. c-style) comment can be terminated by
-typing a slash at the start of a line.
-
-**** `c-one-liner-defun'
-This clean-up compresses a short enough defun (for example, an AWK
-pattern/action pair) onto a single line. "Short enough" is configurable.
-
-*** New lineup functions
-
-**** `c-lineup-string-cont'
-This lineup function lines up a continued string under the one it
-continues. E.g:
-
-result = prefix + "A message "
- "string."; <- c-lineup-string-cont
-
-**** `c-lineup-cascaded-calls'
-Lines up series of calls separated by "->" or ".".
-
-**** `c-lineup-knr-region-comment'
-Gives (what most people think is) better indentation of comments in
-the "K&R region" between the function header and its body.
-
-**** `c-lineup-gcc-asm-reg'
-Provides better indentation inside asm blocks.
-
-**** `c-lineup-argcont'
-Lines up continued function arguments after the preceding comma.
-
-*** Added toggle for syntactic indentation.
-The function `c-toggle-syntactic-indentation' can be used to toggle
-syntactic indentation.
-
-*** Better caching of the syntactic context.
-CC Mode caches the positions of the opening parentheses (of any kind)
-of the lists surrounding the point. Those positions are used in many
-places as anchor points for various searches. The cache is now
-improved so that it can be reused to a large extent when the point is
-moved. The less it moves, the less needs to be recalculated.
-
-The effect is that CC Mode should be fast most of the time even when
-opening parens are hung (i.e. aren't in column zero). It's typically
-only the first time after the point is moved far down in a complex
-file that it'll take noticeable time to find out the syntactic
-context.
-
-*** Statements are recognized in a more robust way.
-Statements are recognized most of the time even when they occur in an
-"invalid" context, e.g. in a function argument. In practice that can
-happen when macros are involved.
-
-*** Improved the way `c-indent-exp' chooses the block to indent.
-It now indents the block for the closest sexp following the point
-whose closing paren ends on a different line. This means that the
-point doesn't have to be immediately before the block to indent.
-Also, only the block and the closing line is indented; the current
-line is left untouched.
-
-** Changes in Makefile mode
-
-*** Makefile mode has submodes for automake, gmake, makepp, BSD make and imake.
-
-The former two couldn't be differentiated before, and the latter three
-are new. Font-locking is robust now and offers new customizable
-faces.
-
-*** The variable `makefile-query-one-target-method' has been renamed
-to `makefile-query-one-target-method-function'. The old name is still
-available as alias.
-
-** Sql changes
-
-*** The variable `sql-product' controls the highlighting of different
-SQL dialects. This variable can be set globally via Customize, on a
-buffer-specific basis via local variable settings, or for the current
-session using the new SQL->Product submenu. (This menu replaces the
-SQL->Highlighting submenu.)
-
-The following values are supported:
-
- ansi ANSI Standard (default)
- db2 DB2
- informix Informix
- ingres Ingres
- interbase Interbase
- linter Linter
- ms Microsoft
- mysql MySQL
- oracle Oracle
- postgres Postgres
- solid Solid
- sqlite SQLite
- sybase Sybase
-
-The current product name will be shown on the mode line following the
-SQL mode indicator.
-
-The technique of setting `sql-mode-font-lock-defaults' directly in
-your `.emacs' will no longer establish the default highlighting -- Use
-`sql-product' to accomplish this.
-
-ANSI keywords are always highlighted.
-
-*** The function `sql-add-product-keywords' can be used to add
-font-lock rules to the product specific rules. For example, to have
-all identifiers ending in `_t' under MS SQLServer treated as a type,
-you would use the following line in your .emacs file:
-
- (sql-add-product-keywords 'ms
- '(("\\<\\w+_t\\>" . font-lock-type-face)))
-
-*** Oracle support includes keyword highlighting for Oracle 9i.
-
-Most SQL and PL/SQL keywords are implemented. SQL*Plus commands are
-highlighted in `font-lock-doc-face'.
-
-*** Microsoft SQLServer support has been significantly improved.
-
-Keyword highlighting for SqlServer 2000 is implemented.
-sql-interactive-mode defaults to use osql, rather than isql, because
-osql flushes its error stream more frequently. Thus error messages
-are displayed when they occur rather than when the session is
-terminated.
-
-If the username and password are not provided to `sql-ms', osql is
-called with the `-E' command line argument to use the operating system
-credentials to authenticate the user.
-
-*** Postgres support is enhanced.
-Keyword highlighting of Postgres 7.3 is implemented. Prompting for
-the username and the pgsql `-U' option is added.
-
-*** MySQL support is enhanced.
-Keyword highlighting of MySql 4.0 is implemented.
-
-*** Imenu support has been enhanced to locate tables, views, indexes,
-packages, procedures, functions, triggers, sequences, rules, and
-defaults.
-
-*** Added SQL->Start SQLi Session menu entry which calls the
-appropriate `sql-interactive-mode' wrapper for the current setting of
-`sql-product'.
-
-*** sql.el supports the SQLite interpreter--call 'sql-sqlite'.
-
-** Fortran mode changes
-
-*** F90 mode and Fortran mode have support for `hs-minor-mode' (hideshow).
-It cannot deal with every code format, but ought to handle a sizeable
-majority.
-
-*** F90 mode and Fortran mode have new navigation commands
-`f90-end-of-block', `f90-beginning-of-block', `f90-next-block',
-`f90-previous-block', `fortran-end-of-block',
-`fortran-beginning-of-block'.
-
-*** Fortran mode does more font-locking by default. Use level 3
-highlighting for the old default.
-
-*** Fortran mode has a new variable `fortran-directive-re'.
-Adapt this to match the format of any compiler directives you use.
-Lines that match are never indented, and are given distinctive font-locking.
-
-*** The new function `f90-backslash-not-special' can be used to change
-the syntax of backslashes in F90 buffers.
-
-** Miscellaneous programming mode changes
-
-*** In sh-script, a continuation line is only indented if the backslash was
-preceded by a SPC or a TAB.
-
-*** Perl mode has a new variable `perl-indent-continued-arguments'.
-
-*** The old Octave mode bindings C-c f and C-c i have been changed
-to C-c C-f and C-c C-i. The C-c C-i subcommands now have duplicate
-bindings on control characters--thus, C-c C-i C-b is the same as
-C-c C-i b, and so on.
-
-*** Prolog mode has a new variable `prolog-font-lock-keywords'
-to support use of font-lock.
-
-** VC Changes
-
-*** New backends for Subversion and Meta-CVS.
-
-*** The new variable `vc-cvs-global-switches' specifies switches that
-are passed to any CVS command invoked by VC.
-
-These switches are used as "global options" for CVS, which means they
-are inserted before the command name. For example, this allows you to
-specify a compression level using the `-z#' option for CVS.
-
-*** The key C-x C-q only changes the read-only state of the buffer
-(toggle-read-only). It no longer checks files in or out.
-
-We made this change because we held a poll and found that many users
-were unhappy with the previous behavior. If you do prefer this
-behavior, you can bind `vc-toggle-read-only' to C-x C-q in your
-`.emacs' file:
-
- (global-set-key "\C-x\C-q" 'vc-toggle-read-only)
-
-The function `vc-toggle-read-only' will continue to exist.
-
-*** VC-Annotate mode enhancements
-
-In VC-Annotate mode, you can now use the following key bindings for
-enhanced functionality to browse the annotations of past revisions, or
-to view diffs or log entries directly from vc-annotate-mode:
-
- P: annotates the previous revision
- N: annotates the next revision
- J: annotates the revision at line
- A: annotates the revision previous to line
- D: shows the diff of the revision at line with its previous revision
- L: shows the log of the revision at line
- W: annotates the workfile (most up to date) version
-
-** pcl-cvs changes
-
-*** In pcl-cvs mode, there is a new `d y' command to view the diffs
-between the local version of the file and yesterday's head revision
-in the repository.
-
-*** In pcl-cvs mode, there is a new `d r' command to view the changes
-anyone has committed to the repository since you last executed
-`checkout', `update' or `commit'. That means using cvs diff options
--rBASE -rHEAD.
-
-** Diff changes
-
-*** M-x diff uses Diff mode instead of Compilation mode.
-
-*** Diff mode key bindings changed.
-
-These are the new bindings:
-
-C-c C-e diff-ediff-patch (old M-A)
-C-c C-n diff-restrict-view (old M-r)
-C-c C-r diff-reverse-direction (old M-R)
-C-c C-u diff-context->unified (old M-U)
-C-c C-w diff-refine-hunk (old C-c C-r)
-
-To convert unified to context format, use C-u C-c C-u.
-In addition, C-c C-u now operates on the region
-in Transient Mark mode when the mark is active.
-
-** EDiff changes.
-
-*** When comparing directories.
-Typing D brings up a buffer that lists the differences between the contents of
-directories. Now it is possible to use this buffer to copy the missing files
-from one directory to another.
-
-*** When comparing files or buffers.
-Typing the = key now offers to perform the word-by-word comparison of the
-currently highlighted regions in an inferior Ediff session. If you answer 'n'
-then it reverts to the old behavior and asks the user to select regions for
-comparison.
-
-*** The new command `ediff-backup' compares a file with its most recent
-backup using `ediff'. If you specify the name of a backup file,
-`ediff-backup' compares it with the file of which it is a backup.
-
-** Etags changes.
-
-*** New regular expressions features
-
-**** New syntax for regular expressions, multi-line regular expressions.
-
-The syntax --ignore-case-regexp=/regex/ is now undocumented and retained
-only for backward compatibility. The new equivalent syntax is
---regex=/regex/i. More generally, it is --regex=/TAGREGEX/TAGNAME/MODS,
-where `/TAGNAME' is optional, as usual, and MODS is a string of 0 or
-more characters among `i' (ignore case), `m' (multi-line) and `s'
-(single-line). The `m' and `s' modifiers behave as in Perl regular
-expressions: `m' allows regexps to match more than one line, while `s'
-(which implies `m') means that `.' matches newlines. The ability to
-span newlines allows writing of much more powerful regular expressions
-and rapid prototyping for tagging new languages.
-
-**** Regular expressions can use char escape sequences as in GCC.
-
-The escaped character sequence \a, \b, \d, \e, \f, \n, \r, \t, \v,
-respectively, stand for the ASCII characters BEL, BS, DEL, ESC, FF, NL,
-CR, TAB, VT.
-
-**** Regular expressions can be bound to a given language.
-
-The syntax --regex={LANGUAGE}REGEX means that REGEX is used to make tags
-only for files of language LANGUAGE, and ignored otherwise. This is
-particularly useful when storing regexps in a file.
-
-**** Regular expressions can be read from a file.
-
-The address@hidden option means read the regexps from a file, one
-per line. Lines beginning with space or tab are ignored.
-
-*** New language parsing features
-
-**** New language HTML.
-
-Tags are generated for `title' as well as `h1', `h2', and `h3'. Also,
-when `name=' is used inside an anchor and whenever `id=' is used.
-
-**** New language PHP.
-
-Functions, classes and defines are tags. If the --members option is
-specified to etags, variables are tags also.
-
-**** New language Lua.
-
-All functions are tagged.
-
-**** The `::' qualifier triggers C++ parsing in C file.
-
-Previously, only the `template' and `class' keywords had this effect.
-
-**** The GCC __attribute__ keyword is now recognized and ignored.
-
-**** In C and derived languages, etags creates tags for #undef
-
-**** In Makefiles, constants are tagged.
-
-If you want the old behavior instead, thus avoiding to increase the
-size of the tags file, use the --no-globals option.
-
-**** In Perl, packages are tags.
-
-Subroutine tags are named from their package. You can jump to sub tags
-as you did before, by the sub name, or additionally by looking for
-package::sub.
-
-**** In Prolog, etags creates tags for rules in addition to predicates.
-
-**** New default keywords for TeX.
-
-The new keywords are def, newcommand, renewcommand, newenvironment and
-renewenvironment.
-
-*** Honor #line directives.
-
-When Etags parses an input file that contains C preprocessor's #line
-directives, it creates tags using the file name and line number
-specified in those directives. This is useful when dealing with code
-created from Cweb source files. When Etags tags the generated file, it
-writes tags pointing to the source file.
-
-*** New option --parse-stdin=FILE.
-
-This option is mostly useful when calling etags from programs. It can
-be used (only once) in place of a file name on the command line. Etags
-reads from standard input and marks the produced tags as belonging to
-the file FILE.
-
-*** The --members option is now the default.
-
-Use --no-members if you want the old default behaviour of not tagging
-struct members in C, members variables in C++ and variables in PHP.
-
-** Ctags changes.
-
-*** Ctags now allows duplicate tags
-
-** Rmail changes
-
-*** Support for `movemail' from GNU mailutils was added to Rmail.
-
-This version of `movemail' allows to read mail from a wide range of
-mailbox formats, including remote POP3 and IMAP4 mailboxes with or
-without TLS encryption. If GNU mailutils is installed on the system
-and its version of `movemail' can be found in exec-path, it will be
-used instead of the native one.
-
-*** The new commands rmail-end-of-message and rmail-summary end-of-message,
-by default bound to `/', go to the end of the current mail message in
-Rmail and Rmail summary buffers.
-
-*** Rmail now displays 5-digit message ids in its summary buffer.
-
-** Gnus package
-
-*** Gnus now includes Sieve and PGG
-
-Sieve is a library for managing Sieve scripts. PGG is a library to handle
-PGP/MIME.
-
-*** There are many news features, bug fixes and improvements.
-
-See the file GNUS-NEWS or the node "Oort Gnus" in the Gnus manual for details.
-
-** MH-E changes.
-
-Upgraded to MH-E version 8.0.3. There have been major changes since
-version 5.0.2; see MH-E-NEWS for details.
-
-** Miscellaneous mail changes
-
-*** The new variable `mail-default-directory' specifies
-`default-directory' for mail buffers. This directory is used for
-auto-save files of mail buffers. It defaults to "~/".
-
-*** The mode line can indicate new mail in a directory or file.
-
-See the documentation of the user option `display-time-mail-directory'.
-
-** Calendar changes
-
-*** There is a new calendar package, icalendar.el, that can be used to
-convert Emacs diary entries to/from the iCalendar format.
-
-*** The new package cal-html.el writes HTML files with calendar and
-diary entries.
-
-*** The new functions `diary-from-outlook', `diary-from-outlook-gnus',
-and `diary-from-outlook-rmail' can be used to import diary entries
-from Outlook-format appointments in mail messages. The variable
-`diary-outlook-formats' can be customized to recognize additional
-formats.
-
-*** The procedure for activating appointment reminders has changed:
-use the new function `appt-activate'. The new variable
-`appt-display-format' controls how reminders are displayed, replacing
-`appt-issue-message', `appt-visible', and `appt-msg-window'.
-
-*** The function `simple-diary-display' now by default sets a header line.
-This can be controlled through the variables `diary-header-line-flag'
-and `diary-header-line-format'.
-
-*** Diary sexp entries can have custom marking in the calendar.
-Diary sexp functions which only apply to certain days (such as
-`diary-block' or `diary-cyclic') now take an optional parameter MARK,
-which is the name of a face or a single-character string indicating
-how to highlight the day in the calendar display. Specifying a
-single-character string as @var{mark} places the character next to the
-day in the calendar. Specifying a face highlights the day with that
-face. This lets you have different colors or markings for vacations,
-appointments, paydays or anything else using a sexp.
-
-*** The meanings of C-x < and C-x > have been interchanged.
-< means to scroll backward in time, and > means to scroll forward.
-
-*** You can now use < and >, instead of C-x < and C-x >, to scroll
-the calendar left or right.
-
-*** The new function `calendar-goto-day-of-year' (g D) prompts for a
-year and day number, and moves to that date. Negative day numbers
-count backward from the end of the year.
-
-*** The new Calendar function `calendar-goto-iso-week' (g w)
-prompts for a year and a week number, and moves to the first
-day of that ISO week.
-
-*** The functions `holiday-easter-etc' and `holiday-advent' now take
-optional arguments, in order to only report on the specified holiday
-rather than all. This makes customization of variables such as
-`christian-holidays' simpler.
-
-*** The new variable `calendar-minimum-window-height' affects the
-window generated by the function `generate-calendar-window'.
-
-** Speedbar changes
-
-*** Speedbar items can now be selected by clicking mouse-1, based on
-the `mouse-1-click-follows-link' mechanism.
-
-*** The new command `speedbar-toggle-line-expansion', bound to SPC,
-contracts or expands the line under the cursor.
-
-*** New command `speedbar-create-directory', bound to `M'.
-
-*** The new commands `speedbar-expand-line-descendants' and
-`speedbar-contract-line-descendants', bound to `[' and `]'
-respectively, expand and contract the line under cursor with all of
-its descendents.
-
-*** The new user option `speedbar-use-tool-tips-flag', if non-nil,
-means to display tool-tips for speedbar items.
-
-*** The new user option `speedbar-query-confirmation-method' controls
-how querying is performed for file operations. A value of 'always
-means to always query before file operations; 'none-but-delete means
-to not query before any file operations, except before a file
-deletion.
-
-*** The new user option `speedbar-select-frame-method' specifies how
-to select a frame for displaying a file opened with the speedbar. A
-value of 'attached means to use the attached frame (the frame that
-speedbar was started from.) A number such as 1 or -1 means to pass
-that number to `other-frame'.
-
-*** SPC and DEL are no longer bound to scroll up/down in the speedbar
-keymap.
-
-*** The frame management code in speedbar.el has been split into a new
-`dframe' library. Emacs Lisp code that makes use of the speedbar
-should use `dframe-attached-frame' instead of
-`speedbar-attached-frame', `dframe-timer' instead of `speedbar-timer',
-`dframe-close-frame' instead of `speedbar-close-frame', and
-`dframe-activity-change-focus-flag' instead of
-`speedbar-activity-change-focus-flag'. The variables
-`speedbar-update-speed' and `speedbar-navigating-speed' are also
-obsolete; use `dframe-update-speed' instead.
-
-** battery.el changes
-
-*** display-battery-mode replaces display-battery.
-
-*** battery.el now works on recent versions of OS X.
-
-** Games
-
-*** The game `mpuz' is enhanced.
-
-`mpuz' now allows the 2nd factor not to have two identical digits. By
-default, all trivial operations involving whole lines are performed
-automatically. The game uses faces for better visual feedback.
-
-** Obsolete and deleted packages
-
-*** fast-lock.el and lazy-lock.el are obsolete. Use jit-lock.el instead.
-
-*** iso-acc.el is now obsolete. Use one of the latin input methods instead.
-
-*** zone-mode.el is now obsolete. Use dns-mode.el instead.
-
-*** cplus-md.el has been deleted.
-
-** Miscellaneous
-
-*** The variable `woman-topic-at-point' is renamed
-to `woman-use-topic-at-point' and behaves differently: if this
-variable is non-nil, the `woman' command uses the word at point
-automatically, without asking for a confirmation. Otherwise, the word
-at point is suggested as default, but not inserted at the prompt.
-
-*** You can now customize `fill-nobreak-predicate' to control where
-filling can break lines. The value is now normally a list of
-functions, but it can also be a single function, for compatibility.
-
-Emacs provide two predicates, `fill-single-word-nobreak-p' and
-`fill-french-nobreak-p', for use as the value of
-`fill-nobreak-predicate'.
-
-*** M-x view-file and commands that use it now avoid interfering
-with special modes such as Tar mode.
-
-*** `global-whitespace-mode' is a new alias for `whitespace-global-mode'.
-
-*** The saveplace.el package now filters out unreadable files.
-
-When you exit Emacs, the saved positions in visited files no longer
-include files that aren't readable, e.g. files that don't exist.
-Customize the new option `save-place-forget-unreadable-files' to nil
-to get the old behavior. The new options `save-place-save-skipped'
-and `save-place-skip-check-regexp' allow further fine-tuning of this
-feature.
-
-*** Commands `winner-redo' and `winner-undo', from winner.el, are now
-bound to C-c <left> and C-c <right>, respectively. This is an
-incompatible change.
-
-*** The type-break package now allows `type-break-file-name' to be nil
-and if so, doesn't store any data across sessions. This is handy if
-you don't want the `.type-break' file in your home directory or are
-annoyed by the need for interaction when you kill Emacs.
-
-*** `ps-print' can now print characters from the mule-unicode charsets.
-
-Printing text with characters from the mule-unicode-* sets works with
-`ps-print', provided that you have installed the appropriate BDF
-fonts. See the file INSTALL for URLs where you can find these fonts.
-
-*** New command `strokes-global-set-stroke-string'.
-This is like `strokes-global-set-stroke', but it allows you to bind
-the stroke directly to a string to insert. This is convenient for
-using strokes as an input method.
-
-*** In Outline mode, `hide-body' no longer hides lines at the top
-of the file that precede the first header line.
-
-*** `hide-ifdef-mode' now uses overlays rather than selective-display
-to hide its text. This should be mostly transparent but slightly
-changes the behavior of motion commands like C-e and C-p.
-
-*** In Artist mode the variable `artist-text-renderer' has been
-renamed to `artist-text-renderer-function'. The old name is still
-available as alias.
-
-*** In Enriched mode, `set-left-margin' and `set-right-margin' are now
-by default bound to `C-c [' and `C-c ]' instead of the former `C-c C-l'
-and `C-c C-r'.
-
-*** `partial-completion-mode' now handles partial completion on directory
names.
-
-*** You can now disable pc-selection-mode after enabling it.
-
-M-x pc-selection-mode behaves like a proper minor mode, and with no
-argument it toggles the mode. Turning off PC-Selection mode restores
-the global key bindings that were replaced by turning on the mode.
-
-*** `uniquify-strip-common-suffix' tells uniquify to prefer
-`file|dir1' and `file|dir2' to `file|dir1/subdir' and `file|dir2/subdir'.
-
-*** New user option `add-log-always-start-new-record'.
-
-When this option is enabled, M-x add-change-log-entry always
-starts a new record regardless of when the last record is.
-
-*** M-x compare-windows now can automatically skip non-matching text to
-resync points in both windows.
-
-*** PO translation files are decoded according to their MIME headers
-when Emacs visits them.
-
-*** Telnet now prompts you for a port number with C-u M-x telnet.
-
-*** calculator.el now has radix grouping mode.
-
-To enable this, set `calculator-output-radix' non-nil. In this mode a
-separator character is used every few digits, making it easier to see
-byte boundaries etc. For more info, see the documentation of the
-variable `calculator-radix-grouping-mode'.
-
-*** LDAP support now defaults to ldapsearch from OpenLDAP version 2.
-
-*** The terminal emulation code in term.el has been improved; it can
-run most curses applications now.
-
-*** Support for `magic cookie' standout modes has been removed.
-
-Emacs still works on terminals that require magic cookies in order to
-use standout mode, but they can no longer display mode-lines in
-inverse-video.
-
-
-* Changes in Emacs 22.1 on non-free operating systems
-
-** The HOME directory defaults to Application Data under the user profile.
-
-If you used a previous version of Emacs without setting the HOME
-environment variable and a `.emacs' was saved, then Emacs will continue
-using C:/ as the default HOME. But if you are installing Emacs afresh,
-the default location will be the "Application Data" (or similar
-localized name) subdirectory of your user profile. A typical location
-of this directory is "C:\Documents and Settings\USERNAME\Application Data",
-where USERNAME is your user name.
-
-This change means that users can now have their own `.emacs' files on
-shared computers, and the default HOME directory is less likely to be
-read-only on computers that are administered by someone else.
-
-** Images are now supported on MS Windows.
-
-PBM and XBM images are supported out of the box. Other image formats
-depend on external libraries. All of these libraries have been ported
-to Windows, and can be found in both source and binary form at
-http://gnuwin32.sourceforge.net/. Note that libpng also depends on
-zlib, and tiff depends on the version of jpeg that it was compiled
-against. For additional information, see nt/INSTALL.
-
-** Sound is now supported on MS Windows.
-
-WAV format is supported on all versions of Windows, other formats such
-as AU, AIFF and MP3 may be supported in the more recent versions of
-Windows, or when other software provides hooks into the system level
-sound support for those formats.
-
-** Tooltips now work on MS Windows.
-
-See the Emacs 21.1 NEWS entry for tooltips for details.
-
-** Pointing devices with more than 3 buttons are now supported on MS Windows.
-
-The new variable `w32-pass-extra-mouse-buttons-to-system' controls
-whether Emacs should handle the extra buttons itself (the default), or
-pass them to Windows to be handled with system-wide functions.
-
-** Passing resources on the command line now works on MS Windows.
-
-You can use --xrm to pass resource settings to Emacs, overriding any
-existing values. For example:
-
- emacs --xrm "Emacs.Background:red" --xrm "Emacs.Geometry:100x20"
-
-will start up Emacs on an initial frame of 100x20 with red background,
-irrespective of geometry or background setting on the Windows registry.
-
-** Emacs takes note of colors defined in Control Panel on MS-Windows.
-
-The Control Panel defines some default colors for applications in much
-the same way as wildcard X Resources do on X. Emacs now adds these
-colors to the colormap prefixed by System (eg SystemMenu for the
-default Menu background, SystemMenuText for the foreground), and uses
-some of them to initialize some of the default faces.
-`list-colors-display' shows the list of System color names, in case
-you wish to use them in other faces.
-
-** Running in a console window in Windows now uses the console size.
-
-Previous versions of Emacs erred on the side of having a usable Emacs
-through telnet, even though that was inconvenient if you use Emacs in
-a local console window with a scrollback buffer. The default value of
-w32-use-full-screen-buffer is now nil, which favors local console
-windows. Recent versions of Windows telnet also work well with this
-setting. If you are using an older telnet server then Emacs detects
-that the console window dimensions that are reported are not sane, and
-defaults to 80x25. If you use such a telnet server regularly at a size
-other than 80x25, you can still manually set
-w32-use-full-screen-buffer to t.
-
-** Different shaped mouse pointers are supported on MS Windows.
-
-The mouse pointer changes shape depending on what is under the pointer.
-
-** On MS Windows, the "system caret" now follows the cursor.
-
-This enables Emacs to work better with programs that need to track the
-cursor, for example screen magnifiers and text to speech programs.
-When such a program is in use, the system caret is made visible
-instead of Emacs drawing its own cursor. This seems to be required by
-some programs. The new variable w32-use-visible-system-caret allows
-the caret visibility to be manually toggled.
-
-** On MS Windows NT/W2K/XP, Emacs uses Unicode for clipboard operations.
-
-Those systems use Unicode internally, so this allows Emacs to share
-multilingual text with other applications. On other versions of
-MS Windows, Emacs now uses the appropriate locale coding-system, so
-the clipboard should work correctly for your local language without
-any customizations.
-
-** On Mac OS, `keyboard-coding-system' changes based on the keyboard script.
-
-** The variable `mac-keyboard-text-encoding' and the constants
-`kTextEncodingMacRoman', `kTextEncodingISOLatin1', and
-`kTextEncodingISOLatin2' are obsolete.
-
-** The variable `mac-command-key-is-meta' is obsolete. Use
-`mac-command-modifier' and `mac-option-modifier' instead.
-
-* Incompatible Lisp Changes in Emacs 22.1
-
-** Mode line display ignores text properties as well as the
-:propertize and :eval forms in the value of a variable whose
-`risky-local-variable' property is nil.
-
-The function `comint-send-input' now accepts 3 optional arguments:
-
- (comint-send-input &optional no-newline artificial)
-
-Callers sending input not from the user should use bind the 3rd
-argument `artificial' to a non-nil value, to prevent Emacs from
-deleting the part of subprocess output that matches the input.
-
-** The `read-file-name' function now returns a null string if the
-user just types RET.
-
-** The variables post-command-idle-hook and post-command-idle-delay have
-been removed. Use run-with-idle-timer instead.
-
-** A hex or octal escape in a string constant forces the string to
-be multibyte or unibyte, respectively.
-
-** The explicit method of creating a display table element by
-combining a face number and a character code into a numeric
-glyph code is deprecated.
-
-Instead, the new functions `make-glyph-code', `glyph-char', and
-`glyph-face' must be used to create and decode glyph codes in
-display tables.
-
-** `suppress-keymap' now works by remapping `self-insert-command' to
-the command `undefined'. (In earlier Emacs versions, it used
-`substitute-key-definition' to rebind self inserting characters to
-`undefined'.)
-
-** The third argument of `accept-process-output' is now milliseconds.
-It used to be microseconds.
-
-** The function find-operation-coding-system may be called with a cons
-(FILENAME . BUFFER) in the second argument if the first argument
-OPERATION is `insert-file-contents', and thus a function registered in
-`file-coding-system-alist' is also called with such an argument.
-
-** When Emacs receives a USR1 or USR2 signal, this generates
-input events: sigusr1 or sigusr2. Use special-event-map to
-handle these events.
-
-** The variable `memory-full' now remains t until
-there is no longer a shortage of memory.
-
-** Support for Mocklisp has been removed.
-
-
-* Lisp Changes in Emacs 22.1
-
-** General Lisp changes:
-
-*** New syntax: \s now stands for the SPACE character.
-
-`?\s' is a new way to write the space character. You must make sure
-it is not followed by a dash, since `?\s-...' indicates the "super"
-modifier. However, it would be strange to write a character constant
-and a following symbol (beginning with `-') with no space between
-them.
-
-`\s' stands for space in strings, too, but it is not really meant for
-strings; it is easier and nicer just to write a space.
-
-*** New syntax: \uXXXX and \UXXXXXXXX specify Unicode code points in hex.
-
-For instance, you can use "\u0428" to specify a string consisting of
-CYRILLIC CAPITAL LETTER SHA, or `"U0001D6E2" to specify one consisting
-of MATHEMATICAL ITALIC CAPITAL ALPHA (the latter is greater than
-#xFFFF and thus needs the longer syntax).
-
-This syntax works for both character constants and strings.
-
-*** New function `unsafep' determines whether a Lisp form is safe.
-
-It returns nil if the given Lisp form can't possibly do anything
-dangerous; otherwise it returns a reason why the form might be unsafe
-(calls unknown function, alters global variable, etc.).
-
-*** The function `eql' is now available without requiring the CL package.
-
-*** The new function `memql' is like `memq', but uses `eql' for comparison,
-that is, floats are compared by value and other elements with `eq'.
-
-*** New functions `string-or-null-p' and `booleanp'.
-
-`string-or-null-p' returns non-nil iff OBJECT is a string or nil.
-`booleanp' returns non-nil iff OBJECT is t or nil.
-
-*** `makehash' is now obsolete. Use `make-hash-table' instead.
-
-*** Minor change in the function `format'.
-
-Some flags that were accepted but not implemented (such as "*") are no
-longer accepted.
-
-*** `add-to-list' takes an optional third argument, APPEND.
-
-If APPEND is non-nil, the new element gets added at the end of the
-list instead of at the beginning. This change actually occurred in
-Emacs 21.1, but was not documented then.
-
-*** New function `add-to-ordered-list' is like `add-to-list' but
-associates a numeric ordering of each element added to the list.
-
-*** New function `add-to-history' adds an element to a history list.
-
-Lisp packages should use this function to add elements to their
-history lists.
-
-If `history-delete-duplicates' is non-nil, it removes duplicates of
-the new element from the history list it updates.
-
-*** New function `copy-tree' makes a copy of a tree.
-
-It recursively copies through both CARs and CDRs.
-
-*** New function `delete-dups' deletes `equal' duplicate elements from a list.
-
-It modifies the list destructively, like `delete'. Of several `equal'
-occurrences of an element in the list, the one that's kept is the
-first one.
-
-*** New function `rassq-delete-all'.
-
-(rassq-delete-all VALUE ALIST) deletes, from ALIST, each element whose
-CDR is `eq' to the specified value.
-
-*** Functions `get' and `plist-get' no longer give errors for bad plists.
-
-They return nil for a malformed property list or if the list is
-cyclic.
-
-*** New functions `lax-plist-get' and `lax-plist-put'.
-
-They are like `plist-get' and `plist-put', except that they compare
-the property name using `equal' rather than `eq'.
-
-*** The function `number-sequence' makes a list of equally-separated numbers.
-
-For instance, (number-sequence 4 9) returns (4 5 6 7 8 9). By
-default, the separation is 1, but you can specify a different
-separation as the third argument. (number-sequence 1.5 6 2) returns
-(1.5 3.5 5.5).
-
-*** New variables `most-positive-fixnum' and `most-negative-fixnum'.
-
-They hold the largest and smallest possible integer values.
-
-*** The function `expt' handles negative exponents differently.
-The value for `(expt A B)', if both A and B are integers and B is
-negative, is now a float. For example: (expt 2 -2) => 0.25.
-
-*** The function `atan' now accepts an optional second argument.
-
-When called with 2 arguments, as in `(atan Y X)', `atan' returns the
-angle in radians between the vector [X, Y] and the X axis. (This is
-equivalent to the standard C library function `atan2'.)
-
-*** New macro `with-case-table'
-
-This executes the body with the case table temporarily set to a given
-case table.
-
-*** New macro `with-local-quit' temporarily allows quitting.
-
-A quit inside the body of `with-local-quit' is caught by the
-`with-local-quit' form itself, but another quit will happen later once
-the code that has inhibited quitting exits.
-
-This is for use around potentially blocking or long-running code
-inside timer functions and `post-command-hook' functions.
-
-*** New macro `define-obsolete-function-alias'.
-
-This combines `defalias' and `make-obsolete'.
-
-*** New macro `eval-at-startup' specifies expressions to
-evaluate when Emacs starts up. If this is done after startup,
-it evaluates those expressions immediately.
-
-This is useful in packages that can be preloaded.
-
-*** New function `macroexpand-all' expands all macros in a form.
-
-It is similar to the Common-Lisp function of the same name.
-One difference is that it guarantees to return the original argument
-if no expansion is done, which can be tested using `eq'.
-
-*** A function or macro's doc string can now specify the calling pattern.
-
-You put this info in the doc string's last line. It should be
-formatted so as to match the regexp "\n\n(fn .*)\\'". If you don't
-specify this explicitly, Emacs determines it from the actual argument
-names. Usually that default is right, but not always.
-
-*** New variable `print-continuous-numbering'.
-
-When this is non-nil, successive calls to print functions use a single
-numbering scheme for circular structure references. This is only
-relevant when `print-circle' is non-nil.
-
-When you bind `print-continuous-numbering' to t, you should
-also bind `print-number-table' to nil.
-
-*** `list-faces-display' takes an optional argument, REGEXP.
-
-If it is non-nil, the function lists only faces matching this regexp.
-
-*** New hook `command-error-function'.
-
-By setting this variable to a function, you can control
-how the editor command loop shows the user an error message.
-
-*** `debug-on-entry' accepts primitive functions that are not special forms.
-
-** Lisp code indentation features:
-
-*** The `defmacro' form can contain indentation and edebug declarations.
-
-These declarations specify how to indent the macro calls in Lisp mode
-and how to debug them with Edebug. You write them like this:
-
- (defmacro NAME LAMBDA-LIST [DOC-STRING] [DECLARATION ...] ...)
-
-DECLARATION is a list `(declare DECLARATION-SPECIFIER ...)'. The
-possible declaration specifiers are:
-
-(indent INDENT)
- Set NAME's `lisp-indent-function' property to INDENT.
-
-(edebug DEBUG)
- Set NAME's `edebug-form-spec' property to DEBUG. (This is
- equivalent to writing a `def-edebug-spec' for the macro,
- but this is cleaner.)
-
-*** cl-indent now allows customization of Indentation of backquoted forms.
-
-See the new user option `lisp-backquote-indentation'.
-
-*** cl-indent now handles indentation of simple and extended `loop' forms.
-
-The new user options `lisp-loop-keyword-indentation',
-`lisp-loop-forms-indentation', and `lisp-simple-loop-indentation' can
-be used to customize the indentation of keywords and forms in loop
-forms.
-
-** Variable aliases:
-
-*** New function: defvaralias ALIAS-VAR BASE-VAR [DOCSTRING]
-
-This function defines the symbol ALIAS-VAR as a variable alias for
-symbol BASE-VAR. This means that retrieving the value of ALIAS-VAR
-returns the value of BASE-VAR, and changing the value of ALIAS-VAR
-changes the value of BASE-VAR.
-
-DOCSTRING, if present, is the documentation for ALIAS-VAR; else it has
-the same documentation as BASE-VAR.
-
-*** The macro `define-obsolete-variable-alias' combines `defvaralias' and
-`make-obsolete-variable'.
-
-*** New function: indirect-variable VARIABLE
-
-This function returns the variable at the end of the chain of aliases
-of VARIABLE. If VARIABLE is not a symbol, or if VARIABLE is not
-defined as an alias, the function returns VARIABLE.
-
-It might be noteworthy that variables aliases work for all kinds of
-variables, including buffer-local and frame-local variables.
-
-** defcustom changes:
-
-*** The package-version keyword has been added to provide
-`customize-changed-options' functionality to packages in the future.
-Developers who make use of this keyword must also update the new
-variable `customize-package-emacs-version-alist'.
-
-*** The new customization type `float' requires a floating point number.
-
-** String changes:
-
-*** A hex escape in a string constant forces the string to be multibyte.
-
-*** An octal escape in a string constant forces the string to be unibyte.
-
-*** New function `string-to-multibyte' converts a unibyte string to a
-multibyte string with the same individual character codes.
-
-*** `split-string' now includes null substrings in the returned list if
-the optional argument SEPARATORS is non-nil and there are matches for
-SEPARATORS at the beginning or end of the string. If SEPARATORS is
-nil, or if the new optional third argument OMIT-NULLS is non-nil, all
-empty matches are omitted from the returned list.
-
-*** The new function `assoc-string' replaces `assoc-ignore-case' and
-`assoc-ignore-representation', which are still available, but have
-been declared obsolete.
-
-*** New function `substring-no-properties' returns a substring without
-text properties.
-
-** Displaying warnings to the user.
-
-See the functions `warn' and `display-warning', or the Lisp Manual.
-If you want to be sure the warning will not be overlooked, this
-facility is much better than using `message', since it displays
-warnings in a separate window.
-
-** Progress reporters.
-
-These provide a simple and uniform way for commands to present
-progress messages for the user.
-
-See the new functions `make-progress-reporter',
-`progress-reporter-update', `progress-reporter-force-update',
-`progress-reporter-done', and `dotimes-with-progress-reporter'.
-
-** Buffer positions:
-
-*** Function `compute-motion' now calculates the usable window
-width if the WIDTH argument is nil. If the TOPOS argument is nil,
-the usable window height and width is used.
-
-*** The `line-move', `scroll-up', and `scroll-down' functions will now
-modify the window vscroll to scroll through display rows that are
-taller that the height of the window, for example in the presence of
-large images. To disable this feature, bind the new variable
-`auto-window-vscroll' to nil.
-
-*** The argument to `forward-word', `backward-word' is optional.
-
-It defaults to 1.
-
-*** Argument to `forward-to-indentation' and `backward-to-indentation' is
optional.
-
-It defaults to 1.
-
-*** `field-beginning' and `field-end' take new optional argument, LIMIT.
-
-This argument tells them not to search beyond LIMIT. Instead they
-give up and return LIMIT.
-
-*** New function `window-line-height' is an efficient way to get
-information about a specific text line in a window provided that the
-window's display is up-to-date.
-
-*** New function `line-number-at-pos' returns the line number of a position.
-
-It an optional buffer position argument that defaults to point.
-
-*** Function `pos-visible-in-window-p' now returns the pixel coordinates
-and partial visibility state of the corresponding row, if the PARTIALLY
-arg is non-nil.
-
-*** New functions `posn-at-point' and `posn-at-x-y' return
-click-event-style position information for a given visible buffer
-position or for a given window pixel coordinate.
-
-*** New function `mouse-on-link-p' tests if a position is in a clickable link.
-
-This is the function used by the new `mouse-1-click-follows-link'
-functionality.
-
-** Text modification:
-
-*** The new function `buffer-chars-modified-tick' returns a buffer's
-tick counter for changes to characters. Each time text in that buffer
-is inserted or deleted, the character-change counter is updated to the
-tick counter (`buffer-modified-tick'). Text property changes leave it
-unchanged.
-
-*** The new function `insert-for-yank' normally works like `insert', but
-removes the text properties in the `yank-excluded-properties' list
-and handles the `yank-handler' text property.
-
-*** The new function `insert-buffer-substring-as-yank' is like
-`insert-for-yank' except that it gets the text from another buffer as
-in `insert-buffer-substring'.
-
-*** The new function `insert-buffer-substring-no-properties' is like
-`insert-buffer-substring', but removes all text properties from the
-inserted substring.
-
-*** The new function `filter-buffer-substring' extracts a buffer
-substring, passes it through a set of filter functions, and returns
-the filtered substring. Use it instead of `buffer-substring' or
-`delete-and-extract-region' when copying text into a user-accessible
-data structure, such as the kill-ring, X clipboard, or a register.
-
-The list of filter function is specified by the new variable
-`buffer-substring-filters'. For example, Longlines mode adds to
-`buffer-substring-filters' to remove soft newlines from the copied
-text.
-
-*** Function `translate-region' accepts also a char-table as TABLE
-argument.
-
-*** The new translation table `translation-table-for-input'
-is used for customizing self-insertion. The character to
-be inserted is translated through it.
-
-*** Text clones.
-
-The new function `text-clone-create'. Text clones are chunks of text
-that are kept identical by transparently propagating changes from one
-clone to the other.
-
-*** The function `insert-string' is now obsolete.
-
-** Filling changes.
-
-*** In determining an adaptive fill prefix, Emacs now tries the function in
-`adaptive-fill-function' _before_ matching the buffer line against
-`adaptive-fill-regexp' rather than _after_ it.
-
-** Atomic change groups.
-
-To perform some changes in the current buffer "atomically" so that
-they either all succeed or are all undone, use `atomic-change-group'
-around the code that makes changes. For instance:
-
- (atomic-change-group
- (insert foo)
- (delete-region x y))
-
-If an error (or other nonlocal exit) occurs inside the body of
-`atomic-change-group', it unmakes all the changes in that buffer that
-were during the execution of the body. The change group has no effect
-on any other buffers--any such changes remain.
-
-If you need something more sophisticated, you can directly call the
-lower-level functions that `atomic-change-group' uses. Here is how.
-
-To set up a change group for one buffer, call `prepare-change-group'.
-Specify the buffer as argument; it defaults to the current buffer.
-This function returns a "handle" for the change group. You must save
-the handle to activate the change group and then finish it.
-
-Before you change the buffer again, you must activate the change
-group. Pass the handle to `activate-change-group' afterward to
-do this.
-
-After you make the changes, you must finish the change group. You can
-either accept the changes or cancel them all. Call
-`accept-change-group' to accept the changes in the group as final;
-call `cancel-change-group' to undo them all.
-
-You should use `unwind-protect' to make sure the group is always
-finished. The call to `activate-change-group' should be inside the
-`unwind-protect', in case the user types C-g just after it runs.
-(This is one reason why `prepare-change-group' and
-`activate-change-group' are separate functions.) Once you finish the
-group, don't use the handle again--don't try to finish the same group
-twice.
-
-To make a multibuffer change group, call `prepare-change-group' once
-for each buffer you want to cover, then use `nconc' to combine the
-returned values, like this:
-
- (nconc (prepare-change-group buffer-1)
- (prepare-change-group buffer-2))
-
-You can then activate the multibuffer change group with a single call
-to `activate-change-group', and finish it with a single call to
-`accept-change-group' or `cancel-change-group'.
-
-Nested use of several change groups for the same buffer works as you
-would expect. Non-nested use of change groups for the same buffer
-will lead to undesirable results, so don't let it happen; the first
-change group you start for any given buffer should be the last one
-finished.
-
-** Buffer-related changes:
-
-*** The new function `buffer-local-value' returns the buffer-local
-binding of VARIABLE (a symbol) in buffer BUFFER. If VARIABLE does not
-have a buffer-local binding in buffer BUFFER, it returns the default
-value of VARIABLE instead.
-
-*** `list-buffers-noselect' now takes an additional argument, BUFFER-LIST.
-
-If it is non-nil, it specifies which buffers to list.
-
-*** `kill-buffer-hook' is now a permanent local.
-
-*** The function `frame-or-buffer-changed-p' now lets you maintain
-various status records in parallel.
-
-It takes a variable (a symbol) as argument. If the variable is non-nil,
-then its value should be a vector installed previously by
-`frame-or-buffer-changed-p'. If the frame names, buffer names, buffer
-order, or their read-only or modified flags have changed, since the
-time the vector's contents were recorded by a previous call to
-`frame-or-buffer-changed-p', then the function returns t. Otherwise
-it returns nil.
-
-On the first call to `frame-or-buffer-changed-p', the variable's
-value should be nil. `frame-or-buffer-changed-p' stores a suitable
-vector into the variable and returns t.
-
-If the variable is itself nil, then `frame-or-buffer-changed-p' uses,
-for compatibility, an internal variable which exists only for this
-purpose.
-
-*** The function `read-buffer' follows the convention for reading from
-the minibuffer with a default value: if DEF is non-nil, the minibuffer
-prompt provided in PROMPT is edited to show the default value provided
-in DEF before the terminal colon and space.
-
-** Searching and matching changes:
-
-*** New function `looking-back' checks whether a regular expression matches
-the text before point. Specifying the LIMIT argument bounds how far
-back the match can start; this is a way to keep it from taking too long.
-
-*** The new variable `search-spaces-regexp' controls how to search
-for spaces in a regular expression. If it is non-nil, it should be a
-regular expression, and any series of spaces stands for that regular
-expression. If it is nil, spaces stand for themselves.
-
-Spaces inside of constructs such as `[..]' and inside loops such as
-`*', `+', and `?' are never replaced with `search-spaces-regexp'.
-
-*** New regular expression operators, `\_<' and `\_>'.
-
-These match the beginning and end of a symbol. A symbol is a
-non-empty sequence of either word or symbol constituent characters, as
-specified by the syntax table.
-
-*** `skip-chars-forward' and `skip-chars-backward' now handle
-character classes such as `[:alpha:]', along with individual
-characters and ranges.
-
-*** In `replace-match', the replacement text no longer inherits
-properties from surrounding text.
-
-*** The list returned by `(match-data t)' now has the buffer as a final
-element, if the last match was on a buffer. `set-match-data'
-accepts such a list for restoring the match state.
-
-*** Functions `match-data' and `set-match-data' now have an optional
-argument `reseat'. When non-nil, all markers in the match data list
-passed to these functions will be reseated to point to nowhere.
-
-*** rx.el has new corresponding `symbol-start' and `symbol-end' elements.
-
-*** The default value of `sentence-end' is now defined using the new
-variable `sentence-end-without-space', which contains such characters
-that end a sentence without following spaces.
-
-The function `sentence-end' should be used to obtain the value of the
-variable `sentence-end'. If the variable `sentence-end' is nil, then
-this function returns the regexp constructed from the variables
-`sentence-end-without-period', `sentence-end-double-space' and
-`sentence-end-without-space'.
-
-** Undo changes:
-
-*** `buffer-undo-list' allows programmable elements.
-
-These elements have the form (apply FUNNAME . ARGS), where FUNNAME is
-a symbol other than t or nil. That stands for a high-level change
-that should be undone by evaluating (apply FUNNAME ARGS).
-
-These entries can also have the form (apply DELTA BEG END FUNNAME . ARGS)
-which indicates that the change which took place was limited to the
-range BEG...END and increased the buffer size by DELTA.
-
-*** If the buffer's undo list for the current command gets longer than
-`undo-outer-limit', garbage collection empties it. This is to prevent
-it from using up the available memory and choking Emacs.
-
-** Killing and yanking changes:
-
-*** New `yank-handler' text property can be used to control how
-previously killed text on the kill ring is reinserted.
-
-The value of the `yank-handler' property must be a list with one to four
-elements with the following format:
- (FUNCTION PARAM NOEXCLUDE UNDO).
-
-The `insert-for-yank' function looks for a yank-handler property on
-the first character on its string argument (typically the first
-element on the kill-ring). If a `yank-handler' property is found,
-the normal behavior of `insert-for-yank' is modified in various ways:
-
- When FUNCTION is present and non-nil, it is called instead of `insert'
-to insert the string. FUNCTION takes one argument--the object to insert.
- If PARAM is present and non-nil, it replaces STRING as the object
-passed to FUNCTION (or `insert'); for example, if FUNCTION is
-`yank-rectangle', PARAM should be a list of strings to insert as a
-rectangle.
- If NOEXCLUDE is present and non-nil, the normal removal of the
-`yank-excluded-properties' is not performed; instead FUNCTION is
-responsible for removing those properties. This may be necessary
-if FUNCTION adjusts point before or after inserting the object.
- If UNDO is present and non-nil, it is a function that will be called
-by `yank-pop' to undo the insertion of the current object. It is
-called with two arguments, the start and end of the current region.
-FUNCTION can set `yank-undo-function' to override the UNDO value.
-
-*** The functions `kill-new', `kill-append', and `kill-region' now have an
-optional argument to specify the `yank-handler' text property to put on
-the killed text.
-
-*** The function `yank-pop' will now use a non-nil value of the variable
-`yank-undo-function' (instead of `delete-region') to undo the previous
-`yank' or `yank-pop' command (or a call to `insert-for-yank'). The function
-`insert-for-yank' automatically sets that variable according to the UNDO
-element of the string argument's `yank-handler' text property if present.
-
-*** The function `insert-for-yank' now supports strings where the
-`yank-handler' property does not span the first character of the
-string. The old behavior is available if you call
-`insert-for-yank-1' instead.
-
-** Syntax table changes:
-
-*** The new function `syntax-ppss' provides an efficient way to find the
-current syntactic context at point.
-
-*** The new function `syntax-after' returns the syntax code
-of the character after a specified buffer position, taking account
-of text properties as well as the character code.
-
-*** `syntax-class' extracts the class of a syntax code (as returned
-by `syntax-after').
-
-*** The macro `with-syntax-table' no longer copies the syntax table.
-
-** File operation changes:
-
-*** New vars `exec-suffixes' and `load-suffixes' used when
-searching for an executable or an Emacs Lisp file.
-
-*** New function `locate-file' searches for a file in a list of directories.
-`locate-file' accepts a name of a file to search (a string), and two
-lists: a list of directories to search in and a list of suffixes to
-try; typical usage might use `exec-path' and `load-path' for the list
-of directories, and `exec-suffixes' and `load-suffixes' for the list
-of suffixes. The function also accepts a predicate argument to
-further filter candidate files.
-
-One advantage of using this function is that the list of suffixes in
-`exec-suffixes' is OS-dependant, so this function will find
-executables without polluting Lisp code with OS dependencies.
-
-*** The new function `file-remote-p' tests a file name and returns
-non-nil if it specifies a remote file (one that Emacs accesses using
-its own special methods and not directly through the file system).
-The value in that case is an identifier for the remote file system.
-
-*** The new hook `before-save-hook' is invoked by `basic-save-buffer'
-before saving buffers. This allows packages to perform various final
-tasks. For example, it can be used by the copyright package to make
-sure saved files have the current year in any copyright headers.
-
-*** `file-chase-links' now takes an optional second argument LIMIT which
-specifies the maximum number of links to chase through. If after that
-many iterations the file name obtained is still a symbolic link,
-`file-chase-links' returns it anyway.
-
-*** Functions `file-name-sans-extension' and `file-name-extension' now
-ignore the leading dots in file names, so that file names such as
-`.emacs' are treated as extensionless.
-
-*** If `buffer-save-without-query' is non-nil in some buffer,
-`save-some-buffers' will always save that buffer without asking (if
-it's modified).
-
-*** `buffer-auto-save-file-format' is the new name for what was
-formerly called `auto-save-file-format'. It is now a permanent local.
-
-*** `visited-file-modtime' and `calendar-time-from-absolute' now return
-a list of two integers, instead of a cons.
-
-*** The precedence of file name handlers has been changed.
-
-Instead of choosing the first handler that matches,
-`find-file-name-handler' now gives precedence to a file name handler
-that matches nearest the end of the file name. More precisely, the
-handler whose (match-beginning 0) is the largest is chosen. In case
-of ties, the old "first matched" rule applies.
-
-*** A file name handler can declare which operations it handles.
-
-You do this by putting an `operation' property on the handler name
-symbol. The property value should be a list of the operations that
-the handler really handles. It won't be called for any other
-operations.
-
-This is useful for autoloaded handlers, to prevent them from being
-autoloaded when not really necessary.
-
-*** The function `make-auto-save-file-name' is now handled by file
-name handlers. This will be exploited for remote files mainly.
-
-*** The function `file-name-completion' accepts an optional argument
-PREDICATE, and rejects completion candidates that don't satisfy PREDICATE.
-
-*** The new primitive `set-file-times' sets a file's access and
-modification times. Magic file name handlers can handle this
-operation.
-
-** Input changes:
-
-*** Functions `y-or-n-p', `read-char', `read-key-sequence' and the like, that
-display a prompt but don't use the minibuffer, now display the prompt
-using the text properties (esp. the face) of the prompt string.
-
-*** The functions `read-event', `read-char', and `read-char-exclusive'
-have a new optional argument SECONDS. If non-nil, this specifies a
-maximum time to wait for input, in seconds. If no input arrives after
-this time elapses, the functions stop waiting and return nil.
-
-*** An interactive specification can now use the code letter `U' to get
-the up-event that was discarded in case the last key sequence read for a
-previous `k' or `K' argument was a down-event; otherwise nil is used.
-
-*** The new interactive-specification `G' reads a file name
-much like `F', but if the input is a directory name (even defaulted),
-it returns just the directory name.
-
-*** (while-no-input BODY...) runs BODY, but only so long as no input
-arrives. If the user types or clicks anything, BODY stops as if a
-quit had occurred. `while-no-input' returns the value of BODY, if BODY
-finishes. It returns nil if BODY was aborted by a quit, and t if
-BODY was aborted by arrival of input.
-
-*** `recent-keys' now returns the last 300 keys.
-
-** Minibuffer changes:
-
-*** The new function `minibufferp' returns non-nil if its optional
-buffer argument is a minibuffer. If the argument is omitted, it
-defaults to the current buffer.
-
-*** New function `minibuffer-selected-window' returns the window which
-was selected when entering the minibuffer.
-
-*** The `read-file-name' function now takes an additional argument which
-specifies a predicate which the file name read must satisfy. The
-new variable `read-file-name-predicate' contains the predicate argument
-while reading the file name from the minibuffer; the predicate in this
-variable is used by read-file-name-internal to filter the completion list.
-
-*** The new variable `read-file-name-function' can be used by Lisp code
-to override the built-in `read-file-name' function.
-
-*** The new variable `read-file-name-completion-ignore-case' specifies
-whether completion ignores case when reading a file name with the
-`read-file-name' function.
-
-*** The new function `read-directory-name' is for reading a directory name.
-
-It is like `read-file-name' except that the defaulting works better
-for directories, and completion inside it shows only directories.
-
-*** The new variable `history-add-new-input' specifies whether to add new
-elements in history. If set to nil, minibuffer reading functions don't
-add new elements to the history list, so it is possible to do this
-afterwards by calling `add-to-history' explicitly.
-
-** Completion changes:
-
-*** The new function `minibuffer-completion-contents' returns the contents
-of the minibuffer just before point. That is what completion commands
-operate on.
-
-*** The functions `all-completions' and `try-completion' now accept lists
-of strings as well as hash-tables additionally to alists, obarrays
-and functions. Furthermore, the function `test-completion' is now
-exported to Lisp. The keys in alists and hash tables can be either
-strings or symbols, which are automatically converted with to strings.
-
-*** The new macro `dynamic-completion-table' supports using functions
-as a dynamic completion table.
-
- (dynamic-completion-table FUN)
-
-FUN is called with one argument, the string for which completion is required,
-and it should return an alist containing all the intended possible
-completions. This alist can be a full list of possible completions so that FUN
-can ignore the value of its argument. If completion is performed in the
-minibuffer, FUN will be called in the buffer from which the minibuffer was
-entered. `dynamic-completion-table' then computes the completion.
-
-*** The new macro `lazy-completion-table' initializes a variable
-as a lazy completion table.
-
- (lazy-completion-table VAR FUN)
-
-If the completion table VAR is used for the first time (e.g., by passing VAR
-as an argument to `try-completion'), the function FUN is called with no
-arguments. FUN must return the completion table that will be stored in VAR.
-If completion is requested in the minibuffer, FUN will be called in the buffer
-from which the minibuffer was entered. The return value of
-`lazy-completion-table' must be used to initialize the value of VAR.
-
-** Abbrev changes:
-
-*** `define-abbrev' now accepts an optional argument SYSTEM-FLAG.
-
-If non-nil, this marks the abbrev as a "system" abbrev, which means
-that it won't be stored in the user's abbrevs file if he saves the
-abbrevs. Major modes that predefine some abbrevs should always
-specify this flag.
-
-*** The new function `copy-abbrev-table' copies an abbrev table.
-
-It returns a new abbrev table that is a copy of a given abbrev table.
-
-** Enhancements to keymaps.
-
-*** Cleaner way to enter key sequences.
-
-You can enter a constant key sequence in a more natural format, the
-same one used for saving keyboard macros, using the macro `kbd'. For
-example,
-
-(kbd "C-x C-f") => "\^x\^f"
-
-Actually, this format has existed since Emacs 20.1.
-
-*** Interactive commands can be remapped through keymaps.
-
-This is an alternative to using `defadvice' or `substitute-key-definition'
-to modify the behavior of a key binding using the normal keymap
-binding and lookup functionality.
-
-When a key sequence is bound to a command, and that command is
-remapped to another command, that command is run instead of the
-original command.
-
-Example:
-Suppose that minor mode `my-mode' has defined the commands
-`my-kill-line' and `my-kill-word', and it wants C-k (and any other key
-bound to `kill-line') to run the command `my-kill-line' instead of
-`kill-line', and likewise it wants to run `my-kill-word' instead of
-`kill-word'.
-
-Instead of rebinding C-k and the other keys in the minor mode map,
-command remapping allows you to directly map `kill-line' into
-`my-kill-line' and `kill-word' into `my-kill-word' using `define-key':
-
- (define-key my-mode-map [remap kill-line] 'my-kill-line)
- (define-key my-mode-map [remap kill-word] 'my-kill-word)
-
-When `my-mode' is enabled, its minor mode keymap is enabled too. So
-when the user types C-k, that runs the command `my-kill-line'.
-
-Only one level of remapping is supported. In the above example, this
-means that if `my-kill-line' is remapped to `other-kill', then C-k still
-runs `my-kill-line'.
-
-The following changes have been made to provide command remapping:
-
-- Command remappings are defined using `define-key' with a prefix-key
- `remap', i.e. `(define-key MAP [remap CMD] DEF)' remaps command CMD
- to definition DEF in keymap MAP. The definition is not limited to
- another command; it can be anything accepted for a normal binding.
-
-- The new function `command-remapping' returns the binding for a
- remapped command in the current keymaps, or nil if not remapped.
-
-- `key-binding' now remaps interactive commands unless the optional
- third argument NO-REMAP is non-nil.
-
-- `where-is-internal' now returns nil for a remapped command (e.g.
- `kill-line', when `my-mode' is enabled), and the actual key binding for
- the command it is remapped to (e.g. C-k for my-kill-line).
- It also has a new optional fifth argument, NO-REMAP, which inhibits
- remapping if non-nil (e.g. it returns "C-k" for `kill-line', and
- "<kill-line>" for `my-kill-line').
-
-- The new variable `this-original-command' contains the original
- command before remapping. It is equal to `this-command' when the
- command was not remapped.
-
-*** The definition of a key-binding passed to define-key can use XEmacs-style
-key-sequences, such as [(control a)].
-
-*** New keymaps for typing file names
-
-Two new keymaps, `minibuffer-local-filename-completion-map' and
-`minibuffer-local-must-match-filename-map', apply whenever
-Emacs reads a file name in the minibuffer. These key maps override
-the usual binding of SPC to `minibuffer-complete-word' (so that file
-names with embedded spaces could be typed without the need to quote
-the spaces).
-
-*** New function `current-active-maps' returns a list of currently
-active keymaps.
-
-*** New function `describe-buffer-bindings' inserts the list of all
-defined keys and their definitions.
-
-*** New function `keymap-prompt' returns the prompt string of a keymap.
-
-*** If text has a `keymap' property, that keymap takes precedence
-over minor mode keymaps.
-
-*** The `keymap' property now also works at the ends of overlays and
-text properties, according to their stickiness. This also means that it
-works with empty overlays. The same hold for the `local-map' property.
-
-*** `key-binding' will now look up mouse-specific bindings. The
-keymaps consulted by `key-binding' will get adapted if the key
-sequence is started with a mouse event. Instead of letting the click
-position be determined from the key sequence itself, it is also
-possible to specify it with an optional argument explicitly.
-
-*** `define-key-after' now accepts keys longer than 1.
-
-*** (map-keymap FUNCTION KEYMAP) applies the function to each binding
-in the keymap.
-
-*** New variable `emulation-mode-map-alists'.
-
-Lisp packages using many minor mode keymaps can now maintain their own
-keymap alist separate from `minor-mode-map-alist' by adding their
-keymap alist to this list.
-
-*** Dense keymaps now handle inheritance correctly.
-
-Previously a dense keymap would hide all of the simple-char key
-bindings of the parent keymap.
-
-** Enhancements to process support
-
-*** Adaptive read buffering of subprocess output.
-
-On some systems, when Emacs reads the output from a subprocess, the
-output data is read in very small blocks, potentially resulting in
-very poor performance. This behavior can be remedied to some extent
-by setting the new variable `process-adaptive-read-buffering' to a
-non-nil value (the default), as it will automatically delay reading
-from such processes, allowing them to produce more output before
-Emacs tries to read it.
-
-*** Processes now have an associated property list where programs can
-maintain process state and other per-process related information.
-
-Use the new functions `process-get' and `process-put' to access, add,
-and modify elements on this property list. Use the new functions
-`process-plist' and `set-process-plist' to access and replace the
-entire property list of a process.
-
-*** Function `list-processes' now has an optional argument; if non-nil,
-it lists only the processes whose query-on-exit flag is set.
-
-*** New fns `set-process-query-on-exit-flag' and `process-query-on-exit-flag'.
-
-These replace the old function `process-kill-without-query'. That
-function is still supported, but new code should use the new
-functions.
-
-*** The new function `call-process-shell-command'.
-
-This executes a shell command synchronously in a separate process.
-
-*** The new function `process-file' is similar to `call-process', but
-obeys file handlers. The file handler is chosen based on
-`default-directory'.
-
-*** Function `signal-process' now accepts a process object or process
-name in addition to a process id to identify the signaled process.
-
-*** Function `accept-process-output' has a new optional fourth arg
-JUST-THIS-ONE. If non-nil, only output from the specified process
-is handled, suspending output from other processes. If value is an
-integer, also inhibit running timers. This feature is generally not
-recommended, but may be necessary for specific applications, such as
-speech synthesis.
-
-*** A process filter function gets the output as multibyte string
-if the process specifies t for its filter's multibyteness.
-
-That multibyteness is decided by the value of
-`default-enable-multibyte-characters' when the process is created, and
-you can change it later with `set-process-filter-multibyte'.
-
-*** The new function `set-process-filter-multibyte' sets the
-multibyteness of the strings passed to the process's filter.
-
-*** The new function `process-filter-multibyte-p' returns the
-multibyteness of the strings passed to the process's filter.
-
-*** If a process's coding system is `raw-text' or `no-conversion' and its
-buffer is multibyte, the output of the process is at first converted
-to multibyte by `string-to-multibyte' then inserted in the buffer.
-Previously, it was converted to multibyte by `string-as-multibyte',
-which was not compatible with the behavior of file reading.
-
-** Enhanced networking support.
-
-*** The new `make-network-process' function makes network connections.
-It allows opening of stream and datagram connections to a server, as well as
-create a stream or datagram server inside Emacs.
-
-- A server is started using :server t arg.
-- Datagram connection is selected using :type 'datagram arg.
-- A server can open on a random port using :service t arg.
-- Local sockets are supported using :family 'local arg.
-- IPv6 is supported (when available). You may explicitly select IPv6
- using :family 'ipv6 arg.
-- Non-blocking connect is supported using :nowait t arg.
-- The process' property list can be initialized using :plist PLIST arg;
- a copy of the server process' property list is automatically inherited
- by new client processes created to handle incoming connections.
-
-To test for the availability of a given feature, use featurep like this:
- (featurep 'make-network-process '(:type datagram))
- (featurep 'make-network-process '(:family ipv6))
-
-*** The old `open-network-stream' now uses `make-network-process'.
-
-*** `process-contact' has an optional KEY argument.
-
-Depending on this argument, you can get the complete list of network
-process properties or a specific property. Using :local or :remote as
-the KEY, you get the address of the local or remote end-point.
-
-An Inet address is represented as a 5 element vector, where the first
-4 elements contain the IP address and the fifth is the port number.
-
-*** New functions `stop-process' and `continue-process'.
-
-These functions stop and restart communication through a network
-connection. For a server process, no connections are accepted in the
-stopped state. For a client process, no input is received in the
-stopped state.
-
-*** New function `format-network-address'.
-
-This function reformats the Lisp representation of a network address
-to a printable string. For example, an IP address A.B.C.D and port
-number P is represented as a five element vector [A B C D P], and the
-printable string returned for this vector is "A.B.C.D:P". See the doc
-string for other formatting options.
-
-*** New function `network-interface-list'.
-
-This function returns a list of network interface names and their
-current network addresses.
-
-*** New function `network-interface-info'.
-
-This function returns the network address, hardware address, current
-status, and other information about a specific network interface.
-
-*** New functions `process-datagram-address', `set-process-datagram-address'.
-
-These functions are used with datagram-based network processes to get
-and set the current address of the remote partner.
-
-*** Deleting a network process with `delete-process' calls the sentinel.
-
-The status message passed to the sentinel for a deleted network
-process is "deleted". The message passed to the sentinel when the
-connection is closed by the remote peer has been changed to
-"connection broken by remote peer".
-
-** Using window objects:
-
-*** You can now make a window as short as one line.
-
-A window that is just one line tall does not display either a mode
-line or a header line, even if the variables `mode-line-format' and
-`header-line-format' call for them. A window that is two lines tall
-cannot display both a mode line and a header line at once; if the
-variables call for both, only the mode line actually appears.
-
-*** The new function `window-inside-edges' returns the edges of the
-actual text portion of the window, not including the scroll bar or
-divider line, the fringes, the display margins, the header line and
-the mode line.
-
-*** The new functions `window-pixel-edges' and `window-inside-pixel-edges'
-return window edges in units of pixels, rather than columns and lines.
-
-*** New function `window-body-height'.
-
-This is like `window-height' but does not count the mode line or the
-header line.
-
-*** The new function `adjust-window-trailing-edge' moves the right
-or bottom edge of a window. It does not move other window edges.
-
-*** The new macro `with-selected-window' temporarily switches the
-selected window without impacting the order of `buffer-list'.
-It saves and restores the current buffer, too.
-
-*** `select-window' takes an optional second argument NORECORD.
-
-This is like `switch-to-buffer'.
-
-*** `save-selected-window' now saves and restores the selected window
-of every frame. This way, it restores everything that can be changed
-by calling `select-window'. It also saves and restores the current
-buffer.
-
-*** `set-window-buffer' has an optional argument KEEP-MARGINS.
-
-If non-nil, that says to preserve the window's current margin, fringe,
-and scroll-bar settings.
-
-*** The new function `window-tree' returns a frame's window tree.
-
-*** The functions `get-lru-window' and `get-largest-window' take an optional
-argument `dedicated'. If non-nil, those functions do not ignore
-dedicated windows.
-
-** Customizable fringe bitmaps
-
-*** There are new display properties, `left-fringe' and `right-fringe',
-that can be used to show a specific bitmap in the left or right fringe
-bitmap of the display line.
-
-Format is `display (left-fringe BITMAP [FACE])', where BITMAP is a
-symbol identifying a fringe bitmap, either built-in or defined with
-`define-fringe-bitmap', and FACE is an optional face name to be used
-for displaying the bitmap instead of the default `fringe' face.
-When specified, FACE is automatically merged with the `fringe' face.
-
-*** New buffer-local variables `fringe-indicator-alist' and
-`fringe-cursor-alist' maps between logical (internal) fringe indicator
-and cursor symbols and the actual fringe bitmaps to be displayed.
-This decouples the logical meaning of the fringe indicators from the
-physical appearance, as well as allowing different fringe bitmaps to
-be used in different windows showing different buffers.
-
-*** New function `define-fringe-bitmap' can now be used to create new
-fringe bitmaps, as well as change the built-in fringe bitmaps.
-
-*** New function `destroy-fringe-bitmap' deletes a fringe bitmap
-or restores a built-in one to its default value.
-
-*** New function `set-fringe-bitmap-face' specifies the face to be
-used for a specific fringe bitmap. The face is automatically merged
-with the `fringe' face, so normally, the face should only specify the
-foreground color of the bitmap.
-
-*** New function `fringe-bitmaps-at-pos' returns the current fringe
-bitmaps in the display line at a given buffer position.
-
-** Other window fringe features:
-
-*** Controlling the default left and right fringe widths.
-
-The default left and right fringe widths for all windows of a frame
-can now be controlled by setting the `left-fringe' and `right-fringe'
-frame parameters to an integer value specifying the width in pixels.
-Setting the width to 0 effectively removes the corresponding fringe.
-
-The actual default fringe widths for the frame may deviate from the
-specified widths, since the combined fringe widths must match an
-integral number of columns. The extra width is distributed evenly
-between the left and right fringe. To force a specific fringe width,
-specify the width as a negative integer (if both widths are negative,
-only the left fringe gets the specified width).
-
-Setting the width to nil (the default), restores the default fringe
-width which is the minimum number of pixels necessary to display any
-of the currently defined fringe bitmaps. The width of the built-in
-fringe bitmaps is 8 pixels.
-
-*** Per-window fringe and scrollbar settings
-
-**** Windows can now have their own individual fringe widths and
-position settings.
-
-To control the fringe widths of a window, either set the buffer-local
-variables `left-fringe-width', `right-fringe-width', or call
-`set-window-fringes'.
-
-To control the fringe position in a window, that is, whether fringes
-are positioned between the display margins and the window's text area,
-or at the edges of the window, either set the buffer-local variable
-`fringes-outside-margins' or call `set-window-fringes'.
-
-The function `window-fringes' can be used to obtain the current
-settings. To make `left-fringe-width', `right-fringe-width', and
-`fringes-outside-margins' take effect, you must set them before
-displaying the buffer in a window, or use `set-window-buffer' to force
-an update of the display margins.
-
-**** Windows can now have their own individual scroll-bar settings
-controlling the width and position of scroll-bars.
-
-To control the scroll-bar of a window, either set the buffer-local
-variables `scroll-bar-mode' and `scroll-bar-width', or call
-`set-window-scroll-bars'. The function `window-scroll-bars' can be
-used to obtain the current settings. To make `scroll-bar-mode' and
-`scroll-bar-width' take effect, you must set them before displaying
-the buffer in a window, or use `set-window-buffer' to force an update
-of the display margins.
-
-** Redisplay features:
-
-*** `sit-for' can now be called with args (SECONDS &optional NODISP).
-
-*** Iconifying or deiconifying a frame no longer makes sit-for return.
-
-*** New function `redisplay' causes an immediate redisplay if no input is
-available, equivalent to (sit-for 0). The call (redisplay t) forces
-an immediate redisplay even if input is pending.
-
-*** New function `force-window-update' can initiate a full redisplay of
-one or all windows. Normally, this is not needed as changes in window
-contents are detected automatically. However, certain implicit
-changes to mode lines, header lines, or display properties may require
-forcing an explicit window update.
-
-*** (char-displayable-p CHAR) returns non-nil if Emacs ought to be able
-to display CHAR. More precisely, if the selected frame's fontset has
-a font to display the character set that CHAR belongs to.
-
-Fontsets can specify a font on a per-character basis; when the fontset
-does that, this value cannot be accurate.
-
-*** You can define multiple overlay arrows via the new
-variable `overlay-arrow-variable-list'.
-
-It contains a list of variables which contain overlay arrow position
-markers, including the original `overlay-arrow-position' variable.
-
-Each variable on this list can have individual `overlay-arrow-string'
-and `overlay-arrow-bitmap' properties that specify an overlay arrow
-string (for non-window terminals) or fringe bitmap (for window
-systems) to display at the corresponding overlay arrow position.
-If either property is not set, the default `overlay-arrow-string' or
-'overlay-arrow-fringe-bitmap' will be used.
-
-*** New `line-height' and `line-spacing' properties for newline characters
-
-A newline can now have `line-height' and `line-spacing' text or overlay
-properties that control the height of the corresponding display row.
-
-If the `line-height' property value is t, the newline does not
-contribute to the height of the display row; instead the height of the
-newline glyph is reduced. Also, a `line-spacing' property on this
-newline is ignored. This can be used to tile small images or image
-slices without adding blank areas between the images.
-
-If the `line-height' property value is a positive integer, the value
-specifies the minimum line height in pixels. If necessary, the line
-height it increased by increasing the line's ascent.
-
-If the `line-height' property value is a float, the minimum line
-height is calculated by multiplying the default frame line height by
-the given value.
-
-If the `line-height' property value is a cons (FACE . RATIO), the
-minimum line height is calculated as RATIO * height of named FACE.
-RATIO is int or float. If FACE is t, it specifies the current face.
-
-If the `line-height' property value is a cons (nil . RATIO), the line
-height is calculated as RATIO * actual height of the line's contents.
-
-If the `line-height' value is a cons (HEIGHT . TOTAL), HEIGHT specifies
-the line height as described above, while TOTAL is any of the forms
-described above and specifies the total height of the line, causing a
-varying number of pixels to be inserted after the line to make it line
-exactly that many pixels high.
-
-If the `line-spacing' property value is an positive integer, the value
-is used as additional pixels to insert after the display line; this
-overrides the default frame `line-spacing' and any buffer local value of
-the `line-spacing' variable.
-
-If the `line-spacing' property is a float or cons, the line spacing
-is calculated as specified above for the `line-height' property.
-
-*** The buffer local `line-spacing' variable can now have a float value,
-which is used as a height relative to the default frame line height.
-
-*** Enhancements to stretch display properties
-
-The display property stretch specification form `(space PROPS)', where
-PROPS is a property list, now allows pixel based width and height
-specifications, as well as enhanced horizontal text alignment.
-
-The value of these properties can now be a (primitive) expression
-which is evaluated during redisplay. The following expressions
-are supported:
-
-EXPR ::= NUM | (NUM) | UNIT | ELEM | POS | IMAGE | FORM
-NUM ::= INTEGER | FLOAT | SYMBOL
-UNIT ::= in | mm | cm | width | height
-ELEM ::= left-fringe | right-fringe | left-margin | right-margin
- | scroll-bar | text
-POS ::= left | center | right
-FORM ::= (NUM . EXPR) | (OP EXPR ...)
-OP ::= + | -
-
-The form `NUM' specifies a fractional width or height of the default
-frame font size. The form `(NUM)' specifies an absolute number of
-pixels. If a symbol is specified, its buffer-local variable binding
-is used. The `in', `mm', and `cm' units specifies the number of
-pixels per inch, milli-meter, and centi-meter, resp. The `width' and
-`height' units correspond to the width and height of the current face
-font. An image specification corresponds to the width or height of
-the image.
-
-The `left-fringe', `right-fringe', `left-margin', `right-margin',
-`scroll-bar', and `text' elements specify to the width of the
-corresponding area of the window.
-
-The `left', `center', and `right' positions can be used with :align-to
-to specify a position relative to the left edge, center, or right edge
-of the text area. One of the above window elements (except `text')
-can also be used with :align-to to specify that the position is
-relative to the left edge of the given area. Once the base offset for
-a relative position has been set (by the first occurrence of one of
-these symbols), further occurrences of these symbols are interpreted as
-the width of the area.
-
-For example, to align to the center of the left-margin, use
- :align-to (+ left-margin (0.5 . left-margin))
-
-If no specific base offset is set for alignment, it is always relative
-to the left edge of the text area. For example, :align-to 0 in a
-header line aligns with the first text column in the text area.
-
-The value of the form `(NUM . EXPR)' is the value of NUM multiplied by
-the value of the expression EXPR. For example, (2 . in) specifies a
-width of 2 inches, while (0.5 . IMAGE) specifies half the width (or
-height) of the specified image.
-
-The form `(+ EXPR ...)' adds up the value of the expressions.
-The form `(- EXPR ...)' negates or subtracts the value of the expressions.
-
-*** Normally, the cursor is displayed at the end of any overlay and
-text property string that may be present at the current window
-position. The cursor can now be placed on any character of such
-strings by giving that character a non-nil `cursor' text property.
-
-*** The display space :width and :align-to text properties are now
-supported on text terminals.
-
-*** Support for displaying image slices
-
-**** New display property (slice X Y WIDTH HEIGHT) can be used with
-an image property to display only a specific slice of the image.
-
-**** Function `insert-image' has new optional fourth arg to
-specify image slice (X Y WIDTH HEIGHT).
-
-**** New function `insert-sliced-image' inserts a given image as a
-specified number of evenly sized slices (rows x columns).
-
-*** Images can now have an associated image map via the :map property.
-
-An image map is an alist where each element has the format (AREA ID PLIST).
-An AREA is specified as either a rectangle, a circle, or a polygon:
-A rectangle is a cons (rect . ((X0 . Y0) . (X1 . Y1))) specifying the
-pixel coordinates of the upper left and bottom right corners.
-A circle is a cons (circle . ((X0 . Y0) . R)) specifying the center
-and the radius of the circle; R can be a float or integer.
-A polygon is a cons (poly . [X0 Y0 X1 Y1 ...]) where each pair in the
-vector describes one corner in the polygon.
-
-When the mouse pointer is above a hot-spot area of an image, the
-PLIST of that hot-spot is consulted; if it contains a `help-echo'
-property it defines a tool-tip for the hot-spot, and if it contains
-a `pointer' property, it defines the shape of the mouse cursor when
-it is over the hot-spot. See the variable `void-area-text-pointer'
-for possible pointer shapes.
-
-When you click the mouse when the mouse pointer is over a hot-spot,
-an event is composed by combining the ID of the hot-spot with the
-mouse event, e.g. [area4 mouse-1] if the hot-spot's ID is `area4'.
-
-*** The function `find-image' now searches in etc/images/ and etc/.
-The new variable `image-load-path' is a list of locations in which to
-search for image files. The default is to search in etc/images, then
-in etc/, and finally in the directories specified by `load-path'.
-Subdirectories of etc/ and etc/images are not recursively searched; if
-you put an image file in a subdirectory, you have to specify it
-explicitly; for example, if an image is put in etc/images/foo/bar.xpm:
-
- (defimage foo-image '((:type xpm :file "foo/bar.xpm")))
-
-Note that all images formerly located in the lisp directory have been
-moved to etc/images.
-
-*** New function `image-load-path-for-library' returns a suitable
-search path for images relative to library. This function is useful in
-external packages to save users from having to update
-`image-load-path'.
-
-*** The new variable `max-image-size' defines the maximum size of
-images that Emacs will load and display.
-
-*** The new variable `display-mm-dimensions-alist' can be used to
-override incorrect graphical display dimensions returned by functions
-`display-mm-height' and `display-mm-width'.
-
-** Mouse pointer features:
-
-*** The mouse pointer shape in void text areas (i.e. after the end of a
-line or below the last line in the buffer) of the text window is now
-controlled by the new variable `void-text-area-pointer'. The default
-is to use the `arrow' (non-text) pointer. Other choices are `text'
-(or nil), `hand', `vdrag', `hdrag', `modeline', and `hourglass'.
-
-*** The mouse pointer shape over an image can now be controlled by the
-:pointer image property.
-
-*** The mouse pointer shape over ordinary text or images can now be
-controlled/overridden via the `pointer' text property.
-
-** Mouse event enhancements:
-
-*** All mouse events now include a buffer position regardless of where
-you clicked. For mouse clicks in window margins and fringes, this is
-a sensible buffer position corresponding to the surrounding text.
-
-*** Mouse events for clicks on window fringes now specify `left-fringe'
-or `right-fringe' as the area.
-
-*** Mouse events include actual glyph column and row for all event types
-and all areas.
-
-*** Mouse events can now indicate an image object clicked on.
-
-*** Mouse events include relative X and Y pixel coordinates relative to
-the top left corner of the object (image or character) clicked on.
-
-*** Mouse events include the pixel width and height of the object
-(image or character) clicked on.
-
-*** Function `mouse-set-point' now works for events outside text area.
-
-*** `posn-point' now returns buffer position for non-text area events.
-
-*** New function `posn-area' returns window area clicked on (nil means
-text area).
-
-*** New function `posn-actual-col-row' returns the actual glyph coordinates
-of the mouse event position.
-
-*** New functions 'posn-object', 'posn-object-x-y', 'posn-object-width-height'.
-
-These return the image or string object of a mouse click, the X and Y
-pixel coordinates relative to the top left corner of that object, and
-the total width and height of that object.
-
-** Text property and overlay changes:
-
-*** Arguments for `remove-overlays' are now optional, so that you can
-remove all overlays in the buffer with just (remove-overlays).
-
-*** New variable `char-property-alias-alist'.
-
-This variable allows you to create alternative names for text
-properties. It works at the same level as `default-text-properties',
-although it applies to overlays as well. This variable was introduced
-to implement the `font-lock-face' property.
-
-*** New function `get-char-property-and-overlay' accepts the same
-arguments as `get-char-property' and returns a cons whose car is the
-return value of `get-char-property' called with those arguments and
-whose cdr is the overlay in which the property was found, or nil if
-it was found as a text property or not found at all.
-
-*** The new function `remove-list-of-text-properties'.
-
-It is like `remove-text-properties' except that it takes a list of
-property names as argument rather than a property list.
-
-** Face changes
-
-*** The variable `facemenu-unlisted-faces' has been removed.
-Emacs has a lot more faces than in the past, and nearly all of them
-needed to be excluded. The new variable `facemenu-listed-faces' lists
-the faces to include in the face menu.
-
-*** The new face attribute condition `min-colors' can be used to tailor
-the face color to the number of colors supported by a display, and
-define the foreground and background colors accordingly so that they
-look best on a terminal that supports at least this many colors. This
-is now the preferred method for defining default faces in a way that
-makes a good use of the capabilities of the display.
-
-*** New function `display-supports-face-attributes-p' can be used to test
-whether a given set of face attributes is actually displayable.
-
-A new predicate `supports' has also been added to the `defface' face
-specification language, which can be used to do this test for faces
-defined with `defface'.
-
-*** The special treatment of faces whose names are of the form `fg:COLOR'
-or `bg:COLOR' has been removed. Lisp programs should use the
-`defface' facility for defining faces with specific colors, or use
-the feature of specifying the face attributes :foreground and :background
-directly in the `face' property instead of using a named face.
-
-*** The first face specification element in a defface can specify
-`default' instead of frame classification. Then its attributes act as
-defaults that apply to all the subsequent cases (and can be overridden
-by them).
-
-*** The function `face-differs-from-default-p' now truly checks
-whether the given face displays differently from the default face or
-not (previously it did only a very cursory check).
-
-*** `face-attribute', `face-foreground', `face-background', `face-stipple'.
-
-These now accept a new optional argument, INHERIT, which controls how
-face inheritance is used when determining the value of a face
-attribute.
-
-*** New functions `face-attribute-relative-p' and `merge-face-attribute'
-help with handling relative face attributes.
-
-*** The priority of faces in an :inherit attribute face list is reversed.
-
-If a face contains an :inherit attribute with a list of faces, earlier
-faces in the list override later faces in the list; in previous
-releases of Emacs, the order was the opposite. This change was made
-so that :inherit face lists operate identically to face lists in text
-`face' properties.
-
-*** The variable `face-font-rescale-alist' specifies how much larger
-(or smaller) font we should use. For instance, if the value is
-'((SOME-FONTNAME-PATTERN . 1.3)) and a face requests a font of 10
-point, we actually use a font of 13 point if the font matches
-SOME-FONTNAME-PATTERN.
-
-*** On terminals, faces with the :inverse-video attribute are displayed
-with swapped foreground and background colors even when one of them is
-not specified. In previous releases of Emacs, if either foreground
-or background color was unspecified, colors were not swapped. This
-was inconsistent with the face behavior under X.
-
-*** `set-fontset-font', `fontset-info', `fontset-font' now operate on
-the default fontset if the argument NAME is nil..
-
-** Font-Lock changes:
-
-*** New special text property `font-lock-face'.
-
-This property acts like the `face' property, but it is controlled by
-M-x font-lock-mode. It is not, strictly speaking, a builtin text
-property. Instead, it is implemented inside font-core.el, using the
-new variable `char-property-alias-alist'.
-
-*** font-lock can manage arbitrary text-properties beside `face'.
-
-**** the FACENAME returned in `font-lock-keywords' can be a list of the
-form (face FACE PROP1 VAL1 PROP2 VAL2 ...) so you can set other
-properties than `face'.
-
-**** `font-lock-extra-managed-props' can be set to make sure those
-extra properties are automatically cleaned up by font-lock.
-
-*** jit-lock obeys a new text-property `jit-lock-defer-multiline'.
-
-If a piece of text with that property gets contextually refontified
-(see `jit-lock-defer-contextually'), then all of that text will
-be refontified. This is useful when the syntax of a textual element
-depends on text several lines further down (and when `font-lock-multiline'
-is not appropriate to solve that problem). For example in Perl:
-
- s{
- foo
- }{
- bar
- }e
-
-Adding/removing the last `e' changes the `bar' from being a piece of
-text to being a piece of code, so you'd put a `jit-lock-defer-multiline'
-property over the second half of the command to force (deferred)
-refontification of `bar' whenever the `e' is added/removed.
-
-*** `font-lock-extend-region-functions' makes it possible to alter the way
-the fontification region is chosen. This can be used to prevent rounding
-up to whole lines, or to extend the region to include all related lines
-of multiline constructs so that such constructs get properly recognized.
-
-** Major mode mechanism changes:
-
-*** New variable `magic-mode-alist' determines major mode for a file by
-looking at the file contents. It takes precedence over `auto-mode-alist'.
-
-*** New variable `magic-fallback-mode-alist' determines major mode for a file
by
-looking at the file contents. It is handled after `auto-mode-alist',
-only if `auto-mode-alist' (and `magic-mode-alist') says nothing about the file.
-
-*** XML or SGML major mode is selected when file starts with an `<?xml'
-or `<!DOCTYPE' declaration.
-
-*** An interpreter magic line (if present) takes precedence over the
-file name when setting the major mode.
-
-*** If new variable `auto-mode-case-fold' is set to a non-nil value,
-Emacs will perform a second case-insensitive search through
-`auto-mode-alist' if the first case-sensitive search fails. This
-means that a file FILE.TXT is opened in text-mode, and a file
-PROG.HTML is opened in html-mode. Note however, that independent of
-this setting, *.C files are usually recognized as C++ files. It also
-has no effect on systems with case-insensitive file names.
-
-*** All major mode functions should now run the new normal hook
-`after-change-major-mode-hook', at their very end, after the mode
-hooks. `run-mode-hooks' does this automatically.
-
-*** Major modes can define `eldoc-documentation-function'
-locally to provide Eldoc functionality by some method appropriate to
-the language.
-
-*** Use the new function `run-mode-hooks' to run the major mode's mode hook.
-
-*** The new function `run-mode-hooks' and the new macro `delay-mode-hooks'
-are used by `define-derived-mode' to make sure the mode hook for the
-parent mode is run at the end of the child mode.
-
-*** `define-derived-mode' by default creates a new empty abbrev table.
-It does not copy abbrevs from the parent mode's abbrev table.
-
-*** If a major mode function has a non-nil `no-clone-indirect'
-property, `clone-indirect-buffer' signals an error if you use
-it in that buffer.
-
-** Minor mode changes:
-
-*** `define-minor-mode' now accepts arbitrary additional keyword arguments
-and simply passes them to `defcustom', if applicable.
-
-*** `define-globalized-minor-mode'.
-
-This is a new name for what was formerly called
-`easy-mmode-define-global-mode'. The old name remains as an alias.
-
-*** `minor-mode-list' now holds a list of minor mode commands.
-
-** Command loop changes:
-
-*** The new function `called-interactively-p' does what many people
-have mistakenly believed `interactive-p' to do: it returns t if the
-calling function was called through `call-interactively'.
-
-Only use this when you cannot solve the problem by adding a new
-INTERACTIVE argument to the command.
-
-*** The function `commandp' takes an additional optional argument.
-
-If it is non-nil, then `commandp' checks for a function that could be
-called with `call-interactively', and does not return t for keyboard
-macros.
-
-*** When a command returns, the command loop moves point out from
-within invisible text, in the same way it moves out from within text
-covered by an image or composition property.
-
-This makes it generally unnecessary to mark invisible text as intangible.
-This is particularly good because the intangible property often has
-unexpected side-effects since the property applies to everything
-(including `goto-char', ...) whereas this new code is only run after
-`post-command-hook' and thus does not care about intermediate states.
-
-*** If a command sets `transient-mark-mode' to `only', that
-enables Transient Mark mode for the following command only.
-During that following command, the value of `transient-mark-mode'
-is `identity'. If it is still `identity' at the end of the command,
-the next return to the command loop changes to nil.
-
-*** Both the variable and the function `disabled-command-hook' have
-been renamed to `disabled-command-function'. The variable
-`disabled-command-hook' has been kept as an obsolete alias.
-
-*** `emacsserver' now runs `pre-command-hook' and `post-command-hook'
-when it receives a request from emacsclient.
-
-*** `current-idle-time' reports how long Emacs has been idle.
-
-** Lisp file loading changes:
-
-*** `load-history' can now have elements of the form (t . FUNNAME),
-which means FUNNAME was previously defined as an autoload (before the
-current file redefined it).
-
-*** `load-history' now records (defun . FUNNAME) when a function is
-defined. For a variable, it records just the variable name.
-
-*** The function `symbol-file' can now search specifically for function,
-variable or face definitions.
-
-*** `provide' and `featurep' now accept an optional second argument
-to test/provide subfeatures. Also `provide' now checks `after-load-alist'
-and runs any code associated with the provided feature.
-
-*** The variable `recursive-load-depth-limit' has been deleted.
-Emacs now signals an error if the same file is loaded with more
-than 3 levels of nesting.
-
-** Byte compiler changes:
-
-*** The byte compiler now displays the actual line and character
-position of errors, where possible. Additionally, the form of its
-warning and error messages have been brought into line with GNU standards
-for these. As a result, you can use next-error and friends on the
-compilation output buffer.
-
-*** The new macro `with-no-warnings' suppresses all compiler warnings
-inside its body. In terms of execution, it is equivalent to `progn'.
-
-*** You can avoid warnings for possibly-undefined symbols with a
-simple convention that the compiler understands. (This is mostly
-useful in code meant to be portable to different Emacs versions.)
-Write forms like the following, or code that macroexpands into such
-forms:
-
- (if (fboundp 'foo) <then> <else>)
- (if (boundp 'foo) <then> <else)
-
-In the first case, using `foo' as a function inside the <then> form
-won't produce a warning if it's not defined as a function, and in the
-second case, using `foo' as a variable won't produce a warning if it's
-unbound. The test must be in exactly one of the above forms (after
-macro expansion), but such tests can be nested. Note that `when' and
-`unless' expand to `if', but `cond' doesn't.
-
-*** `(featurep 'xemacs)' is treated by the compiler as nil. This
-helps to avoid noisy compiler warnings in code meant to run under both
-Emacs and XEmacs and can sometimes make the result significantly more
-efficient. Since byte code from recent versions of XEmacs won't
-generally run in Emacs and vice versa, this optimization doesn't lose
-you anything.
-
-*** The local variable `no-byte-compile' in Lisp files is now obeyed.
-
-*** When a Lisp file uses CL functions at run-time, compiling the file
-now issues warnings about these calls, unless the file performs
-(require 'cl) when loaded.
-
-** Frame operations:
-
-*** New functions `frame-current-scroll-bars' and `window-current-scroll-bars'.
-
-These functions return the current locations of the vertical and
-horizontal scroll bars in a frame or window.
-
-*** The new function `modify-all-frames-parameters' modifies parameters
-for all (existing and future) frames.
-
-*** The new frame parameter `tty-color-mode' specifies the mode to use
-for color support on character terminal frames. Its value can be a
-number of colors to support, or a symbol. See the Emacs Lisp
-Reference manual for more detailed documentation.
-
-*** When using non-toolkit scroll bars with the default width,
-the `scroll-bar-width' frame parameter value is nil.
-
-** Mode line changes:
-
-*** New function `format-mode-line'.
-
-This returns the mode line or header line of the selected (or a
-specified) window as a string with or without text properties.
-
-*** The new mode-line construct `(:propertize ELT PROPS...)' can be
-used to add text properties to mode-line elements.
-
-*** The new `%i' and `%I' constructs for `mode-line-format' can be used
-to display the size of the accessible part of the buffer on the mode
-line.
-
-*** Mouse-face on mode-line (and header-line) is now supported.
-
-** Menu manipulation changes:
-
-*** To manipulate the File menu using easy-menu, you must specify the
-proper name "file". In previous Emacs versions, you had to specify
-"files", even though the menu item itself was changed to say "File"
-several versions ago.
-
-*** The dummy function keys made by easy-menu are now always lower case.
-If you specify the menu item name "Ada", for instance, it uses `ada'
-as the "key" bound by that key binding.
-
-This is relevant only if Lisp code looks for the bindings that were
-made with easy-menu.
-
-*** `easy-menu-define' now allows you to use nil for the symbol name
-if you don't need to give the menu a name. If you install the menu
-into other keymaps right away (MAPS is non-nil), it usually doesn't
-need to have a name.
-
-** Mule changes:
-
-*** Already true in Emacs 21.1, but not emphasized clearly enough:
-
-Multibyte buffers can now faithfully record all 256 character codes
-from 0 to 255. As a result, most of the past reasons to use unibyte
-buffers no longer exist. We only know of three reasons to use them
-now:
-
-1. If you prefer to use unibyte text all of the time.
-
-2. For reading files into temporary buffers, when you want to avoid
-the time it takes to convert the format.
-
-3. For binary files where format conversion would be pointless and
-wasteful.
-
-*** The new variable `auto-coding-functions' lets you specify functions
-to examine a file being visited and deduce the proper coding system
-for it. (If the coding system is detected incorrectly for a specific
-file, you can put a `coding:' tags to override it.)
-
-*** The new variable `ascii-case-table' stores the case table for the
-ascii character set. Language environments (such as Turkish) may
-alter the case correspondences of ASCII characters. This variable
-saves the original ASCII case table before any such changes.
-
-*** The new function `merge-coding-systems' fills in unspecified aspects
-of one coding system from another coding system.
-
-*** New coding system property `mime-text-unsuitable' indicates that
-the coding system's `mime-charset' is not suitable for MIME text
-parts, e.g. utf-16.
-
-*** New function `decode-coding-inserted-region' decodes a region as if
-it is read from a file without decoding.
-
-*** New CCL functions `lookup-character' and `lookup-integer' access
-hash tables defined by the Lisp function `define-translation-hash-table'.
-
-*** New function `quail-find-key' returns a list of keys to type in the
-current input method to input a character.
-
-*** `set-buffer-file-coding-system' now takes an additional argument,
-NOMODIFY. If it is non-nil, it means don't mark the buffer modified.
-
-** Operating system access:
-
-*** The new primitive `get-internal-run-time' returns the processor
-run time used by Emacs since start-up.
-
-*** Functions `user-uid' and `user-real-uid' now return floats if the
-user UID doesn't fit in a Lisp integer. Function `user-full-name'
-accepts a float as UID parameter.
-
-*** New function `locale-info' accesses locale information.
-
-*** On MS Windows, locale-coding-system is used to interact with the OS.
-The Windows specific variable w32-system-coding-system, which was
-formerly used for that purpose is now an alias for locale-coding-system.
-
-*** New function `redirect-debugging-output' can be used to redirect
-debugging output on the stderr file handle to a file.
-
-** GC changes:
-
-*** New variable `gc-cons-percentage' automatically grows the GC cons threshold
-as the heap size increases.
-
-*** New variables `gc-elapsed' and `gcs-done' provide extra information
-on garbage collection.
-
-*** The normal hook `post-gc-hook' is run at the end of garbage collection.
-
-The hook is run with GC inhibited, so use it with care.
-
-** Miscellaneous:
-
-*** A number of hooks have been renamed to better follow the conventions:
-
-`find-file-hooks' to `find-file-hook',
-`find-file-not-found-hooks' to `find-file-not-found-functions',
-`write-file-hooks' to `write-file-functions',
-`write-contents-hooks' to `write-contents-functions',
-`x-lost-selection-hooks' to `x-lost-selection-functions',
-`x-sent-selection-hooks' to `x-sent-selection-functions',
-`delete-frame-hook' to `delete-frame-functions'.
-
-In each case the old name remains as an alias for the moment.
-
-*** Variable `local-write-file-hooks' is marked obsolete.
-
-Use the LOCAL arg of `add-hook'.
-
-*** New function `x-send-client-message' sends a client message when
-running under X.

-* New Packages for Lisp Programming in Emacs 22.1
-
-** The new library button.el implements simple and fast `clickable
-buttons' in Emacs buffers. Buttons are much lighter-weight than the
-`widgets' implemented by widget.el, and can be used by lisp code that
-doesn't require the full power of widgets. Emacs uses buttons for
-such things as help and apropos buffers.
-
-** The new library tree-widget.el provides a widget to display a set
-of hierarchical data as an outline. For example, the tree-widget is
-well suited to display a hierarchy of directories and files.
-
-** The new library bindat.el provides functions to unpack and pack
-binary data structures, such as network packets, to and from Lisp
-data structures.
-
-** master-mode.el implements a minor mode for scrolling a slave
-buffer without leaving your current buffer, the master buffer.
-
-It can be used by sql.el, for example: the SQL buffer is the master
-and its SQLi buffer is the slave. This allows you to scroll the SQLi
-buffer containing the output from the SQL buffer containing the
-commands.
-
-This is how to use sql.el and master.el together: the variable
-sql-buffer contains the slave buffer. It is a local variable in the
-SQL buffer.
-
-(add-hook 'sql-mode-hook
- (function (lambda ()
- (master-mode t)
- (master-set-slave sql-buffer))))
-(add-hook 'sql-set-sqli-hook
- (function (lambda ()
- (master-set-slave sql-buffer))))
-
-** The new library benchmark.el does timing measurements on Lisp code.
-
-This includes measuring garbage collection time.
-
-** The new library testcover.el does test coverage checking.
-
-This is so you can tell whether you've tested all paths in your Lisp
-code. It works with edebug.
-
-The function `testcover-start' instruments all functions in a given
-file. Then test your code. The function `testcover-mark-all' adds
-overlay "splotches" to the Lisp file's buffer to show where coverage
-is lacking. The command `testcover-next-mark' (bind it to a key!)
-will move point forward to the next spot that has a splotch.
-
-Normally, a red splotch indicates the form was never completely
-evaluated; a brown splotch means it always evaluated to the same
-value. The red splotches are skipped for forms that can't possibly
-complete their evaluation, such as `error'. The brown splotches are
-skipped for forms that are expected to always evaluate to the same
-value, such as (setq x 14).
-
-For difficult cases, you can add do-nothing macros to your code to
-help out the test coverage tool. The macro `noreturn' suppresses a
-red splotch. It is an error if the argument to `noreturn' does
-return. The macro `1value' suppresses a brown splotch for its argument.
-This macro is a no-op except during test-coverage -- then it signals
-an error if the argument actually returns differing values.
