-* Installation Changes in Emacs 29.1
-
----
-** Ahead-of-time native compilation can now be specified via configure.
-Use '--with-native-compilation=aot' to specify that all the Lisp files
-in the Emacs tree should be natively compiled ahead of time. (This is
-slow on most machines.)
-
-+++
-** Emacs can be built with built-in support for accessing SQLite databases.
-This uses the popular sqlite3 library, and can be disabled by using
-the '--without-sqlite3' option to the 'configure' script.
-
-+++
-** Support for the WebP image format.
-This support is built by default when the libwebp library is
-available, and includes support for animated WebP images. To disable
-WebP support, use the '--without-webp' configure flag. Image
-specifiers can now use ':type webp'.
-
-+++
-** Emacs has been ported to the Haiku operating system.
-The configuration process should automatically detect and build for
-Haiku. There is also an optional window-system port to Haiku, which
-can be enabled by configuring Emacs with the option '--with-be-app',
-which will require the Haiku Application Kit development headers and a
-C++ compiler to be present on your system. If Emacs is not built with
-the option '--with-be-app', the resulting Emacs will only run in
-text-mode terminals.
-
-To enable Cairo support, ensure that the Cairo and FreeType
-development files are present on your system, and configure Emacs with
-'--with-be-cairo'.
-
-Unlike X, there is no compile-time option to enable or disable
-double-buffering; it is always enabled. To disable it, change the
-frame parameter 'inhibit-double-buffering' instead.
-
----
-** Emacs now installs the ".pdmp" file using a unique fingerprint in the name.
-The file is typically installed using a file name akin to
-"...dir/libexec/emacs/29.1/x86_64-pc-linux-gnu/emacs-<fingerprint>.pdmp".
-If a constant file name is required, the file can be renamed to
-"emacs.pdmp", and Emacs will find it during startup anyway.
-
----
-** Emacs now uses XInput 2 for input events.
-If your X server has support and you have the XInput 2 development
-headers installed, Emacs will use the X Input Extension for handling
-input. If this causes problems, you can configure Emacs with the
-option '--without-xinput2' to disable this support.
-
-'(featurep 'xinput2)' can be used to test for the presence of XInput 2
-support from Lisp programs.
-
----
-** Emacs no longer reduces the size of the Japanese dictionary.
-Building Emacs includes generation of a Japanese dictionary, which is
-used by Japanese input methods. Previously, the build included a step
-of reducing the size of this dictionary's vocabulary. This vocabulary
-reduction is now optional, by default off. If you need the Emacs
-build to include the vocabulary reduction, configure Emacs with the
-option '--with-small-ja-dic'. In an Emacs source tree already
-configured without that option, you can force the vocabulary reduction
-by saying
-
- make -C leim generate-ja-dic JA_DIC_NO_REDUCTION_OPTION=''
-
-after deleting "lisp/leim/ja-dic/ja-dic.el".
-
-+++
-** Emacs now supports being built with pure GTK.
-To use this option, make sure the GTK 3 (version 3.22.23 or later) and
-Cairo development files are installed, and configure Emacs with the
-option '--with-pgtk'. Unlike the default X and GTK build, the
-resulting Emacs binary will work on any underlying window system
-supported by GDK, such as Wayland and Broadway. We do not recommend
-that you use this configuration, unless you are running a window
-system that's supported by GDK other than X. Running this
-configuration on X is known to have problems, such as undesirable
-frame positioning and various issues with keyboard input of sequences
-such as 'C-;' and 'C-S-u'.
-
----
-** The implementation of overlays has changed.
-Emacs now uses an implementation of overlays that is much more
-efficient than the original one, and should speed up all the
-operations that involve overlays, especially when there are lots of
-them in a buffer. However, no changes in behavior of overlays should
-be visible on the Lisp or user level, with the exception of better
-performance and the order of overlays returned by functions that don't
-promise any particular order.
-
----
-** The docstrings of preloaded files are not in "etc/DOC" any more.
-Instead, they're fetched as needed from the corresponding ".elc" file,
-as was already the case for all the non-preloaded files.
+* Installation Changes in Emacs 30.1
-* Startup Changes in Emacs 29.1
-
-+++
-** '--batch' and '--script' now adjust the garbage collection levels.
-These switches now set 'gc-cons-percentage' to 1.0 (up from the
-default of 0.1). This means that batch processes will typically use
-more memory than before, but use less time doing garbage collection.
-Batch jobs that are supposed to run for a long time should adjust the
-limit back down again.
-
-+++
-** Emacs can now be used more easily in an executable script.
-If you start an executable script with
-
- #!/usr/bin/emacs -x
-
-Emacs will start without reading any init files (like with '--quick'),
-and then execute the rest of the script file as Emacs Lisp. When it
-reaches the end of the script, Emacs will exit with an exit code from
-the value of the final form.
-
-+++
-** New function 'substitute-quotes'.
-This function works like 'substitute-command-keys' but only
-substitutes quote characters.
-
-+++
-** Emacs now supports setting 'user-emacs-directory' via '--init-directory'.
-
-+++
-** Emacs now has a '--fingerprint' option.
-This will output a string identifying the current Emacs build.
-
-+++
-** New hook 'after-pdump-load-hook'.
-This is run at the end of the Emacs startup process, and is meant to
-be used to reinitialize structures that would normally be done at load
-time.
-
-** Native Compilation
-
-+++
-*** New variable 'inhibit-automatic-native-compilation'.
-If set, Emacs will inhibit native compilation (and won't write
-anything to the eln cache automatically). The variable is initialized
-from the 'EMACS_INHIBIT_AUTOMATIC_NATIVE_COMPILATION' environment
-variable on Emacs startup.
-
----
-*** New command 'native-compile-prune-cache'.
-This command deletes older eln cache entries (but not the ones for
-the current Emacs version).
-
----
-*** New function 'startup-redirect-eln-cache'.
-This function can be called in your init files to change the
-user-specific directory where Emacs stores the "*.eln" files produced
-by native compilation of Lisp packages Emacs loads. The default
-eln cache directory is unchanged: it is the "eln-cache" subdirectory
-of 'user-emacs-directory'.
+* Startup Changes in Emacs 30.1
-* Incompatible changes in Emacs 29.1
-
-+++
-** The image commands have changed key bindings.
-In previous Emacs versions, images have had the '+', '-' and 'r' keys
-bound when point is over an image. In Emacs 29.1, additional commands
-were added, and this made it more likely that users would trigger the
-image commands by mistake. To avoid this, all image commands have
-moved to the 'i' keymap, so '+' is now 'i +', '-' is now 'i -', and
-'r' is now 'i r'. In addition, these commands are now repeating, so
-you can rotate an image twice by saying 'i r r', for instance.
-
-+++
-** Emacs now picks the correct coding system for X input methods.
-Previously, Emacs would use the locale coding system for input
-methods, which could in some circumstances be incorrect, especially
-when the input method chose to fall back to some other coding system.
-
-Now, Emacs automatically detects the coding system used by input
-methods, and uses that to decode input in preference to the value of
-'locale-coding-system'. This unfortunately means that users who have
-changed the coding system used to decode X keyboard input must adjust
-their customizations to 'locale-coding-system' to the variable
-'x-input-coding-system' instead.
-
-+++
-** Bookmarks no longer include context for encrypted files.
-If you're visiting an encrypted file, setting a bookmark no longer
-includes excerpts from that buffer in the bookmarks file. This is
-implemented by the new hook 'bookmark-inhibit-context-functions',
-where packages can register a function which returns non-nil for file
-names to be excluded from adding such excerpts.
-
----
-** 'show-paren-mode' is now disabled in 'special-mode' buffers.
-In Emacs versions previous to Emacs 28.1, 'show-paren-mode' defaulted
-off. In Emacs 28.1, the mode was switched on in all buffers. In
-Emacs 29.1, this was changed to be switched on in all editing-related
-buffers, but not in buffers that inherit from 'special-mode'. To get
-back to how things worked in Emacs 28.1, put the following in your
-init file:
-
- (setopt show-paren-predicate t)
-
-+++
-** Explicitly-set read-only state is preserved when reverting a buffer.
-If you use the 'C-x C-q' command to change the read-only state of the
-buffer and then revert it, Emacs would previously use the file
-permission bits to determine whether the buffer should be read-only
-after reverting the buffer. Emacs now remembers the decision made in
-'C-x C-q'.
-
----
-** The Gtk selection face is no longer used for the region.
-The combination of a Gtk-controlled background and a foreground color
-controlled by the internal Emacs machinery led to low-contrast faces
-in common default setups. Emacs now uses the same 'region' face on
-Gtk and non-Gtk setups.
-
-** Dired
-
----
-*** 'w' ('dired-copy-filename-as-kill') has changed behavior.
-If there are several files marked, file names containing space and
-quote characters will be quoted "like this".
-
----
-*** The 'd' command now more consistently skips dot files.
-In previous Emacs versions, commands like 'C-u 10 d' would put the "D"
-mark on the next ten files, no matter whether they were dot files
-(i.e., "." and "..") or not, while marking the next ten lines with the
-mouse (in 'transient-mark-mode') and then hitting 'd' would skip dot
-files. These now work equivalently.
-
-+++
-** Warning about "eager macro-expansion failure" is changed into an error.
-
----
-** Previously, the X "reverseVideo" value at startup was heeded for all frames.
-This meant that if you had a "reverseVideo" resource on the initial
-display, and then opened up a new frame on a display without any
-explicit "reverseVideo" setting, it would get heeded there, too. (This
-included terminal frames.) In Emacs 29, the "reverseVideo" X resource
-is handled like all the other X resources, and set on a per-frame basis.
-
-+++
-** 'E' in 'query-replace' now edits the replacement with exact case.
-Previously, this command did the same as 'e'.
-
----
-** '/ a' in "*Packages*" buffer now limits by archive name(s) instead of
regexp.
-
-+++
-** Setting the goal columns now also affects '<prior>' and '<next>'.
-Previously, 'C-x C-n' only affected 'next-line' and 'previous-line',
-but it now also affects 'scroll-up-command' and 'scroll-down-command'.
-
----
-** Isearch in "*Help*" and "*info*" now char-folds quote characters by default.
-This means that you can say 'C-s `foo' (GRAVE ACCENT) if the buffer
-contains "‘foo" (LEFT SINGLE QUOTATION MARK) and the like. These
-quotation characters look somewhat similar in some fonts. To switch
-this off, disable the new 'isearch-fold-quotes-mode' minor mode.
-
----
-** Sorting commands no longer necessarily change modification status.
-In earlier Emacs versions, commands like 'M-x sort-lines' would always
-change buffer modification status to "modified", whether they changed
-something in the buffer or not. This has been changed: The buffer is
-marked as modified only if the sorting ended up changing the contents
-of the buffer.
-
----
-** 'string-lines' handles trailing newlines differently.
-It no longer returns an empty final string if the string ends with a
-newline.
-
----
-** 'TAB' and '<backtab>' are now bound in 'button-map'.
-This means that if point is on a button, 'TAB' will take you to the
-next button, even if the mode has bound it to something else. This
-also means that 'TAB' on a button in an 'outline-minor-mode' heading
-will move point instead of collapsing the outline.
-
----
-** 'Info-default-directory-list' is no longer populated at Emacs startup.
-If you have code in your init file that removes directories from
-'Info-default-directory-list', this will no longer work.
-
----
-** 'C-k' no longer deletes files in 'ido-mode'.
-To get the previous action back, put something like the following in
-your Init file:
-
- (require 'ido)
- (keymap-set ido-file-completion-map "C-k" #'ido-delete-file-at-head)
-
----
-** New user option 'term-clear-full-screen-programs'.
-By default, term will now work like most terminals when displaying
-full-screen programs: When they exit, the output is cleared, leaving
-what was displayed in the window before the programs started. Set
-this user option to nil to revert back to the old behavior.
-
----
-** Support for old EIEIO functions is not autoloaded any more.
-You need an explicit '(require 'eieio-compat)' to use 'defmethod'
-and 'defgeneric' (which have been made obsolete in Emacs 25.1 with
-'cl-defmethod' and 'cl-defgeneric').
-Similarly you might need to '(require 'eieio-compat)' before loading
-files that were compiled with an old EIEIO (Emacs<25).
-
----
-** 'C-x 8 .' has been moved to 'C-x 8 . .'.
-This is to open up the 'C-x 8 .' map to bind further characters there.
-
----
-** 'C-x 8 =' moved to 'C-x 8 = ='.
-You can now use 'C-x 8 =' to insert several characters with macron;
-for example, 'C-x 8 = a' will insert U+0101 LATIN SMALL LETTER A WITH
-MACRON. To insert a lone macron, type 'C-x 8 = =' instead of the
-previous 'C-x ='.
-
-** Eshell
-
-*** Eshell's PATH is now derived from 'exec-path'.
-For consistency with remote connections, Eshell now uses 'exec-path'
-to determine the execution path on the local system, instead of using
-the PATH environment variable directly.
-
----
-*** 'source' and '.' no longer accept the '--help' option.
-This is for compatibility with the shell versions of these commands,
-which don't handle options like '--help' in any special way.
-
-+++
-*** String delimiters in argument predicates/modifiers are more restricted.
-Previously, some argument predicates/modifiers allowed arbitrary
-characters as string delimiters. To provide more unified behavior
-across all predicates/modifiers, the list of allowed delimiters has
-been restricted to "...", '...', /.../, |...|, (...), [...], <...>,
-and {...}. See the "(eshell) Argument Predication and Modification"
-node in the Eshell manual for more details.
-
-+++
-*** Eshell pipelines now only pipe stdout by default.
-To pipe both stdout and stderr, use the '|&' operator instead of '|'.
-
----
-** The 'delete-forward-char' command now deletes by grapheme clusters.
-This command is by default bound to the <Delete> function key
-(a.k.a. <deletechar>). When invoked without a prefix argument or with
-a positive prefix numeric argument, the command will now delete
-complete grapheme clusters produced by character composition. For
-example, if point is before an Emoji sequence, pressing <Delete> will
-delete the entire sequence, not just a single character at its
-beginning.
-
-+++
-** 'load-history' does not treat autoloads specially any more.
-An autoload definition appears just as a '(defun . NAME)' and the
-'(t . NAME)' entries are not generated any more.
-
----
-** The Tamil input methods no longer insert Tamil digits.
-The input methods 'tamil-itrans' and 'tamil-inscript' no longer insert
-the Tamil digits, as those digit characters are not used nowadays by
-speakers of the Tamil language. To get back the previous behavior,
-use the new 'tamil-itrans-digits' and 'tamil-inscript-digits' input
-methods instead.
-
-+++
-** New variable 'current-time-list' governing default timestamp form.
-Functions like 'current-time' now yield '(TICKS . HZ)' timestamps if
-this new variable is nil. The variable defaults to t, which means
-these functions default to timestamps of the forms '(HI LO US PS)',
-'(HI LO US)' or '(HI LO)', which are less regular and less efficient.
-This is part of a long-planned change first documented in Emacs 27.
-Developers are encouraged to test timestamp-related code with this
-variable set to nil, as it will default to nil in a future Emacs
-version and will be removed some time after that.
-
-+++
-** Functions that recreate the "*scratch*" buffer now also initialize it.
-When functions like 'other-buffer' and 'server-execute' recreate
-"*scratch*", they now also insert 'initial-scratch-message' and set
-the major mode according to 'initial-major-mode', like at Emacs
-startup. Previously, these functions ignored
-'initial-scratch-message' and left "*scratch*" in 'fundamental-mode'.
-
----
-** Naming of Image-Dired thumbnail files has changed.
-Names of thumbnail files generated when 'image-dired-thumbnail-storage'
-is 'image-dired' now always end in ".jpg". This fixes various issues
-on different platforms, but means that thumbnails generated in Emacs 28
-will not be used in Emacs 29, and vice-versa. If disk space is an
-issue, consider deleting the 'image-dired-dir' directory after
-upgrading (usually "~/.emacs.d/image-dired/").
-
----
-** The 'rlogin' method in the URL library is now obsolete.
-Emacs will now display a warning if you request a URL like
-"rlogin://foo@example.org".
-
----
-** Setting 'url-gateway-method' to 'rlogin' is now obsolete.
-Emacs will now display a warning when setting it to that value.
-The user options 'url-gateway-rlogin-host',
-'url-gateway-rlogin-parameters', and 'url-gateway-rlogin-user-name'
-are also obsolete.
-
----
-** The user function 'url-irc-function' now takes a SCHEME argument.
-The user option 'url-irc-function' is now called with a sixth argument
-corresponding to the scheme portion of the target URL. For example,
-this would be "ircs" for a URL like "ircs://irc.libera.chat".
-
----
-** The linum.el library is now obsolete.
-We recommend using either the built-in 'display-line-numbers-mode', or
-the 'nlinum' package from GNU ELPA instead. The former has better
-performance, but the latter is closer to a drop-in replacement.
-
-1. To use 'display-line-numbers-mode', add something like this to your
- Init file:
-
- (global-display-line-numbers-mode 1)
- ;; Alternatively, to use it only in programming modes:
- (add-hook 'prog-mode-hook #'display-line-numbers-mode)
-
-2. To use 'nlinum', add this to your Init file:
-
- (package-install 'nlinum)
- (global-nlinum-mode 1)
- ;; Alternatively, to use it only in programming modes:
- (add-hook 'prog-mode-hook #'nlinum-mode)
-
-3. To continue using the obsolete package 'linum', add this line to
- your Init file, in addition to any existing customizations:
-
- (require 'linum)
-
----
-** The thumbs.el library is now obsolete.
-We recommend using 'M-x image-dired' instead.
-
----
-** The autoarg.el library is now marked obsolete.
-This library provides the 'autoarg-mode' and 'autoarg-kp-mode' minor
-modes to emulate the behavior of the historical editor Twenex Emacs.
-It is believed to no longer be useful.
-
----
-** The quickurl.el library is now obsolete.
-Use 'abbrev', 'skeleton' or 'tempo' instead.
-
----
-** The rlogin.el library, and the 'rsh' command are now obsolete.
-Use something like 'M-x shell RET ssh <host> RET' instead.
-
----
-** The url-about.el library is now obsolete.
-
----
-** The autoload.el library is now obsolete.
-It is superseded by the loaddefs-gen.el library.
-
----
-** The netrc.el library is now obsolete.
-Use the 'auth-source-netrc-parse-all' function in auth-source.el
-instead.
-
----
-** The url-dired.el library is now obsolete.
-
----
-** The fast-lock.el and lazy-lock.el library have been removed.
-They have been obsolete since Emacs 22.1.
-
-The variable 'font-lock-support-mode' is occasionally useful for
-debugging purposes. It is now a regular variable (instead of a user
-option) and can be set to nil to disable Just-in-time Lock mode.
+* Changes in Emacs 30.1
-* Changes in Emacs 29.1
-
-+++
-** New user option 'major-mode-remap-alist' to specify favorite major modes.
-This user option lets you remap the default modes (e.g. 'perl-mode' or
-'latex-mode') to your favorite ones (e.g. 'cperl-mode' or
-'LaTeX-mode') without having to use 'defalias', which can have
-undesirable side effects.
-This applies to all modes specified via 'auto-mode-alist', file-local
-variables, etc.
-
----
-** Emacs now supports Unicode Standard version 15.0.
-
----
-** New user option 'electric-quote-replace-consecutive'.
-
----
-** Emacs is now capable of editing files with very long lines.
-The display of long lines has been optimized, and Emacs should no
-longer choke when a buffer on display contains long lines. The
-variable 'long-line-threshold' controls whether and when these display
-optimizations are in effect.
-
-A companion variable 'large-hscroll-threshold' controls when another
-set of display optimizations are in effect, which are aimed
-specifically at speeding up display of long lines that are truncated.
-
-If you still experience slowdowns while editing files with long lines,
-this may be due to line truncation, or to one of the enabled minor
-modes, or to the current major mode. Try turning off line truncation
-with 'C-x x t', or try disabling all known slow minor modes with
-'M-x so-long-minor-mode', or try disabling both known slow minor modes
-and the major mode with 'M-x so-long-mode', or visit the file with
-'M-x find-file-literally' instead of the usual 'C-x C-f'.
-
-Note that the display optimizations in these cases may cause the
-buffer to be occasionally mis-fontified.
-
-The new function 'long-line-optimizations-p' returns non-nil when
-these optimizations are in effect in the current buffer.
-
-+++
-** New command to change the font size globally.
-To increase the font size, type 'C-x C-M-+' or 'C-x C-M-='; to
-decrease it, type 'C-x C-M--'; to restore the font size, type 'C-x
-C-M-0'. The final key in these commands may be repeated without the
-leading 'C-x' and without the modifiers, e.g. 'C-x C-M-+ C-M-+ C-M-+'
-and 'C-x C-M-+ + +' increase the font size by three steps. When
-'mouse-wheel-mode' is enabled, 'C-M-wheel-up' and 'C-M-wheel-down' also
-increase and decrease the font size globally. Additionally, the
-user option 'global-text-scale-adjust-resizes-frames' controls whether
-the frames are resized when the font size is changed.
-
-** New config variable 'syntax-wholeline-max' to reduce the cost of long lines.
-This variable is used by some operations (mostly syntax-propertization
-and font-locking) to treat lines longer than this variable as if they
-were made up of various smaller lines. This can help reduce the
-slowdowns seen in buffers made of a single long line, but can also
-cause misbehavior in the presence of such long lines (tho most of that
-misbehavior should usually be limited to mis-highlighting). You can
-recover the previous behavior with:
-
- (setq syntax-wholeline-max most-positive-fixnum)
-
----
-** New bindings in 'find-function-setup-keys' for 'find-library'.
-When 'find-function-setup-keys' is enabled, 'C-x L' is now bound to
-'find-library', 'C-x 4 L' is now bound to 'find-library-other-window'
-and 'C-x 5 L' is now bound to 'find-library-other-frame'.
-
-+++
-** New key binding after 'M-x' or 'M-X': 'M-X'.
-Emacs allows different completion predicates to be used with 'M-x'
-(i.e., 'execute-extended-command') via the
-'read-extended-command-predicate' user option. Emacs also has the
-'M-X' (note upper case) command, which only displays commands
-especially relevant to the current buffer. Emacs now allows toggling
-between these modes while the user is inputting a command by hitting
-'M-X' while in the minibuffer.
-
----
-** Interactively, 'kill-buffer' will now offer to save the buffer if unsaved.
-
----
-** New commands 'duplicate-line' and 'duplicate-dwim'.
-'duplicate-line' duplicates the current line the specified number of times.
-'duplicate-dwim' duplicates the region if it is active. If not, it
-works like 'duplicate-line'. An active rectangular region is
-duplicated on its right-hand side.
-
----
-** Files with the ".eld" extension are now visited in 'lisp-data-mode'.
-
-+++
-** 'network-lookup-address-info' can now check numeric IP address validity.
-Specifying 'numeric' as the new optional 'hints' argument makes it
-check if the passed address is a valid IPv4/IPv6 address (without DNS
-traffic).
-
- (network-lookup-address-info "127.1" 'ipv4 'numeric)
- => ([127 0 0 1 0])
-
-+++
-** New command 'find-sibling-file'.
-This command jumps to a file considered a "sibling file", which is
-determined according to the new user option 'find-sibling-rules'.
-
-+++
-** New user option 'delete-selection-temporary-region'.
-When non-nil, 'delete-selection-mode' will only delete the temporary
-regions (usually set by mouse-dragging or shift-selection).
-
-+++
-** New user option 'switch-to-prev-buffer-skip-regexp'.
-This should be a regexp or a list of regexps; buffers whose names
-match those regexps will be ignored by 'switch-to-prev-buffer' and
-'switch-to-next-buffer'.
-
-+++
-** New command 'rename-visited-file'.
-This command renames the file visited by the current buffer by moving
-it to a new location, and also makes the buffer visit this new file.
-
-** Menus
-
----
-*** The entries following the buffers in the "Buffers" menu can now be altered.
-Change the 'menu-bar-buffers-menu-command-entries' variable to alter
-the entries that follow the buffer list.
-
----
-** 'delete-process' is now a command.
-When called interactively, it will kill the process running in the
-current buffer (if any). This can be useful if you have runaway
-output in the current buffer (from a process or a network connection),
-and want to stop it.
-
-+++
-** New command 'restart-emacs'.
-This is like 'save-buffers-kill-emacs', but instead of just killing
-the current Emacs process at the end, it starts a new Emacs process
-(using the same command line arguments as the running Emacs process).
-'kill-emacs' and 'save-buffers-kill-emacs' have also gained new
-optional parameters to restart instead of just killing the current
-process.
-
-+++
-** New user option 'mouse-drag-mode-line-buffer'.
-If non-nil, dragging on the buffer name part of the mode-line will
-drag the buffer's associated file to other programs. This option is
-currently only available on X, Haiku and Nextstep (GNUstep or macOS).
-
-+++
-** New user option 'mouse-drag-and-drop-region-cross-program'.
-If non-nil, this option allows dragging text in the region from Emacs
-to another program.
-
----
-** New user option 'mouse-drag-and-drop-region-scroll-margin'.
-If non-nil, this option allows scrolling a window while dragging text
-around without a scroll wheel.
-
-+++
-*** The value of 'mouse-drag-copy-region' can now be the symbol 'non-empty'.
-This prevents mouse drag gestures from putting empty strings onto the
-kill ring.
-
-+++
-** New user options 'dnd-indicate-insertion-point' and 'dnd-scroll-margin'.
-These options allow adjusting point and scrolling a window when
-dragging items from another program.
-
-+++
-** The X Direct Save (XDS) protocol is now supported.
-This means dropping an image or file link from programs such as
-Firefox will no longer create a temporary file in a random directory,
-instead asking you where to save the file first.
-
-+++
-** New user option 'record-all-keys'.
-If non-nil, this option will force recording of all input keys,
-including those typed in response to passwords prompt (this was the
-previous behavior). The default is nil, which inhibits recording of
-passwords.
-
-+++
-** New function 'command-query'.
-This function makes its argument command prompt the user for
-confirmation before executing.
-
-+++
-** The 'disabled' property of a command's symbol can now be a list.
-The first element of the list should be the symbol 'query', which will
-cause the command disabled this way prompt the user with a y/n or a
-yes/no question before executing. The new function 'command-query' is
-a convenient method of making commands disabled in this way.
-
----
-** 'count-words' will now report buffer totals if given a prefix.
-Without a prefix, it will only report the word count for the narrowed
-part of the buffer.
-
-+++
-** 'count-words' will now report sentence count when used interactively.
-
-** New user option 'set-message-functions'.
-It allows selecting more functions for 'set-message-function'
-in addition to the default function that handles messages
-in the active minibuffer. The most useful are 'inhibit-message'
-that allows specifying a list of messages to inhibit via
-'inhibit-message-regexps', and 'set-multi-message' that
-accumulates recent messages and displays them stacked
-in the echo area.
-
----
-** New user option 'find-library-include-other-files'.
-If set to nil, commands like 'find-library' will only include library
-files in the completion candidates. The default is t, which preserves
-previous behavior, whereby non-library files could also be included.
-
-+++
-** New command 'sqlite-mode-open-file' for examining an sqlite3 file.
-This uses the new 'sqlite-mode' which allows listing the tables in a
-DB file, and examining and modifying the columns and the contents of
-those tables.
-
----
-** 'write-file' will now copy some file mode bits.
-If the current buffer is visiting a file that is executable, the
-'C-x C-w' command will now make the new file executable, too.
-
-+++
-** New user option 'process-error-pause-time'.
-This determines how long to pause Emacs after a process
-filter/sentinel error has been handled.
-
-+++
-** New faces for font-lock.
-These faces are primarily meant for use with tree-sitter. They are:
-'font-lock-bracket-face', 'font-lock-delimiter-face',
-'font-lock-escape-face', 'font-lock-number-face',
-'font-lock-misc-punctuation-face', 'font-lock-operator-face',
-'font-lock-property-face', and 'font-lock-punctuation-face'.
-
-+++
-** New face 'variable-pitch-text'.
-This face is like 'variable-pitch' (from which it inherits), but is
-slightly larger, which should help with the visual size differences
-between the default, non-proportional font and proportional fonts when
-mixed.
-
-+++
-** New face 'mode-line-active'.
-This inherits from the 'mode-line' face, but is the face actually used
-on the mode lines (along with 'mode-line-inactive').
-
-+++
-** New face attribute pseudo-value 'reset'.
-This value stands for the value of the corresponding attribute of the
-'default' face. It can be used to reset attribute values produced by
-inheriting from other faces.
-
-+++
-** New X resource: "borderThickness".
-This controls the thickness of the external borders of the menu bars
-and pop-up menus.
-
-+++
-** New X resource: "inputStyle".
-This controls the style of the pre-edit and status areas of X input
-methods.
-
-+++
-** New X resources: "highlightForeground" and "highlightBackground".
-Only in the Lucid build, this controls colors used for highlighted
-menu item widgets.
-
-+++
-** On X, Emacs now tries to synchronize window resize with the window manager.
-This leads to less flicker and empty areas of a frame being displayed
-when a frame is being resized. Unfortunately, it does not work on
-some ancient buggy window managers, so if Emacs appears to freeze, but
-is still responsive to input, you can turn it off by setting the X
-resource "synchronizeResize" to "off".
-
-+++
-** On X, Emacs can optionally synchronize display with the graphics hardware.
-When this is enabled by setting the X resource "synchronizeResize" to
-"extended", frame content "tearing" is drastically reduced. This is
-only supported on the Motif, Lucid, and no-toolkit builds, and
-requires an X compositing manager supporting the extended frame
-synchronization protocol (see
-https://fishsoup.net/misc/wm-spec-synchronization.html).
-
-This behavior can be toggled on and off via the frame parameter
-'use-frame-synchronization'.
-
-+++
-** New frame parameter 'alpha-background' and X resource "alphaBackground".
-This controls the opacity of the text background when running on a
-composited display.
-
-+++
-** New frame parameter 'shaded'.
-With window managers which support this, it controls whether or not a
-frame's contents will be hidden, leaving only the title bar on display.
-
----
-** New user option 'x-gtk-use-native-input'.
-This controls whether or not GTK input methods are used by Emacs,
-instead of XIM input methods.
-
-+++
-** New user option 'use-system-tooltips'.
-This controls whether to use the toolkit tooltips, or Emacs's own
-native implementation of tooltips as small frames. This option is
-only meaningful if Emacs was built with GTK+, Nextstep, or Haiku
-support, and defaults to t, which makes Emacs use the toolkit
-tooltips. The existing GTK-specific option
-'x-gtk-use-system-tooltips' is now an alias of this new option.
-
-+++
-** Non-native tooltips are now supported on Nextstep.
-This means Emacs built with GNUstep or built on macOS is now able to
-display different faces and images inside tooltips when the
-'use-system-tooltips' user option is nil.
-
----
-** New minor mode 'pixel-scroll-precision-mode'.
-When enabled, and if your mouse supports it, you can scroll the
-display up or down at pixel resolution, according to what your mouse
-wheel reports. Unlike 'pixel-scroll-mode', this mode scrolls the
-display pixel-by-pixel, as opposed to only animating line-by-line
-scrolls.
-
-** Terminal Emacs
-
----
-*** Emacs will now use 24-bit colors on terminals that support "Tc" capability.
-This is in addition to previously-supported ways of discovering 24-bit
-color support: either via the "RGB" or "setf24" capabilities, or if
-the 'COLORTERM' environment variable is set to the value "truecolor".
-
-*** Select active regions with xterm selection support.
-On terminals with xterm setSelection support, the active region may be
-saved to the X primary selection, following the
-'select-active-regions' variable. This support is enabled when
-'tty-select-active-regions' is non-nil.
-
----
-*** New command to set up display of unsupported characters.
-The new command 'standard-display-by-replacement-char' produces Lisp
-code that sets up the 'standard-display-table' to use a replacement
-character for display of characters that the text-mode terminal
-doesn't support. It is most useful with the Linux console and similar
-terminals, where Emacs has a reliable way of determining which
-characters have glyphs in the font loaded into the terminal's memory.
-
----
-*** New functions to set terminal output buffer size.
-The new functions 'tty--set-output-buffer-size' and
-'tty--output-buffer-size' allow setting and retrieving the output
-buffer size of a terminal device. The default buffer size is and has
-always been BUFSIZ, which is defined in your system's stdio.h. When
-you set a buffer size with 'tty--set-output-buffer-size', this also
-prevents Emacs from explicitly flushing the tty output stream, except
-at the end of display update.
-
-** ERT
-
-+++
-*** New ERT variables 'ert-batch-print-length' and 'ert-batch-print-level'.
-These variables will override 'print-length' and 'print-level' when
-printing Lisp values in ERT batch test results.
-
----
-*** Redefining an ERT test in batch mode now signals an error.
-Executing 'ert-deftest' with the same name as an existing test causes
-the previous definition to be discarded, which was probably not
-intended when this occurs in batch mode. To remedy the error, rename
-tests so that they all have unique names.
-
-+++
-*** ERT can generate JUnit test reports.
-When environment variable 'EMACS_TEST_JUNIT_REPORT' is set, ERT
-generates a JUnit test report under this file name. This is useful
-for Emacs integration into CI/CD test environments.
-
----
-*** Unbound test symbols now signal an 'ert-test-unbound' error.
-This affects the 'ert-select-tests' function and its callers.
-
-** Emoji
-
-+++
-*** Emacs now has several new methods for inserting Emojis.
-The Emoji commands are under the new 'C-x 8 e' prefix.
-
-+++
-*** New command 'emoji-insert' (bound to 'C-x 8 e e' and 'C-x 8 e i').
-This command guides you through various Emoji categories and
-combinations in a graphical menu system.
-
-+++
-*** New command 'emoji-search' (bound to 'C-x 8 e s').
-This command lets you search for Emojis based on names.
-
-+++
-*** New command 'emoji-list' (bound to 'C-x 8 e l').
-This command lists all Emojis (categorized by themes) in a special
-buffer and lets you choose one of them.
-
----
-*** New command 'emoji-recent' (bound to 'C-x 8 e r').
-This command lets you choose among the Emojis you have recently
-inserted.
-
-+++
-*** New command 'emoji-describe' (bound to 'C-x 8 e d').
-This command will tell you the name of the Emoji at point. (This
-command also works for non-Emoji characters.)
-
----
-*** New commands 'emoji-zoom-increase' and 'emoji-zoom-decrease'.
-These are bound to 'C-x 8 e +' and 'C-x 8 e -', respectively. They
-can be used on any character, but are mainly useful for emoji.
-
----
-*** New input method 'emoji'.
-This allows you to enter emoji using short strings, eg ':face_palm:'
-or ':scream:'.
-
-** Help
-
----
-*** Variable values displayed by 'C-h v' in "*Help*" are now font-locked.
-
-+++
-*** New user option 'help-clean-buttons'.
-If non-nil, link buttons in "*Help*" will have any surrounding quotes
-removed.
-
----
-*** 'M-x apropos-variable' output now includes values of variables.
-
-+++
-*** New docstring syntax to indicate that symbols shouldn't be links.
-When displaying docstrings in "*Help*" buffers, strings that are
-"`like-this'" are made into links (if they point to a bound
-function/variable). This can lead to false positives when talking
-about values that are symbols that happen to have the same names as
-functions/variables. To inhibit this buttonification, the new
-"\\+`like-this'" syntax can be used.
-
-+++
-*** New user option 'help-window-keep-selected'.
-If non-nil, commands to show the info manual and the source will reuse
-the same window the "*Help*" buffer is shown in.
-
----
-*** Commands like 'C-h f' have changed how they describe menu bindings.
-For instance, previously a command might be described as having the
-following bindings:
-
- It is bound to <open>, C-x C-f, <menu-bar> <file> <new-file>.
-
-This has been changed to:
-
- It is bound to <open> and C-x C-f.
- It can also be invoked from the menu: File → Visit New File...
-
-+++
-*** The 'C-h .' command now accepts a prefix argument.
-'C-u C-h .' would previously inhibit displaying a warning message if
-there's no local help at point. This has been changed to call
-'button-describe'/'widget-describe' and display button/widget help
-instead.
-
----
-*** New user option 'help-enable-variable-value-editing'.
-If enabled, 'e' on a value in "*Help*" will pop you to a new buffer
-where you can edit the value. This is not enabled by default, because
-it's easy to make an edit that yields an invalid result.
-
----
-*** 'C-h b' uses outlining by default.
-Set 'describe-bindings-outline' to nil to get the old behavior.
-
----
-*** Jumping to function/variable source now saves mark before moving point.
-Jumping to source from "*Help*" buffer moves the point when the source
-buffer is already open. Now, the old point is pushed to mark ring.
-
-+++
-*** New key bindings in "*Help*" buffers: 'n' and 'p'.
-These will take you (respectively) to the next and previous "page".
-
----
-*** 'describe-char' now also outputs the name of emoji combinations.
-
-+++
-*** New key binding in "*Help*" buffer: 'I'.
-This will take you to the Emacs Lisp manual entry for the item
-displayed, if any.
-
----
-*** The 'C-h m' ('describe-mode') "*Help*" buffer has been reformatted.
-It now only includes local minor modes at the start, and the global
-minor modes are listed after the major mode.
-
-+++
-*** The user option 'help-window-select' now affects apropos commands.
-The apropos commands will now select the apropos window if
-'help-window-select' is non-nil.
-
----
-*** 'describe-keymap' now considers the symbol at point.
-If the symbol at point is a keymap, 'describe-keymap' suggests it as
-the default candidate.
-
----
-*** New command 'help-quick' displays an overview of common commands.
-The command pops up a buffer at the bottom of the screen with a few
-helpful commands for various tasks. You can toggle the display using
-'C-h q'.
-
-** Outline Mode
-
-+++
-*** Support for customizing the default visibility state of headings.
-Customize the user option 'outline-default-state' to define what
-headings will be visible after Outline mode is turned on. When equal
-to a number, the user option 'outline-default-rules' determines the
-visibility of the subtree starting at the corresponding level. Values
-are provided to control showing a heading subtree depending on whether
-the heading matches a regexp, or on whether its subtree has long lines
-or is itself too long.
-
-** Outline Minor Mode
-
-+++
-*** New user option 'outline-minor-mode-use-buttons'.
-If non-nil, Outline Minor Mode will use buttons to hide/show outlines
-in addition to the ellipsis. The default is nil, but in 'help-mode'
-it has the value 'insert' that inserts the buttons directly to the
-buffer where you can use 'RET' to cycle outline visibility. When
-the value is 'in-margins', Outline Minor Mode uses the window margins
-to hide/show outlines.
-
-** Windows
-
-+++
-*** New commands 'split-root-window-below' and 'split-root-window-right'.
-These commands split the root window in two, and are bound to 'C-x w 2'
-and 'C-x w 3', respectively. A number of other useful window-related
-commands are now available on the 'C-x w' prefix.
-
-+++
-*** New user option 'display-buffer-avoid-small-windows'.
-If non-nil, this should be a window height, a number. Windows smaller
-than this will be avoided by 'display-buffer', if possible.
-
-+++
-*** New display action 'display-buffer-full-frame'.
-This action removes other windows on the frame when displaying a
-buffer.
-
-+++
-*** 'display-buffer' now can set up the body size of the chosen window.
-For example, a 'display-buffer-alist' entry of
-
- '(window-width . (body-columns . 40))'
-
-will make the body of the chosen window 40 columns wide. For the
-height use 'window-height' in combination with 'body-lines'.
-
----
-*** You can customize which window 'scroll-other-window' operates on.
-This is controlled by the new 'other-window-scroll-default' user option.
-
-** Frames
-
-+++
-*** Deleted frames can now be undeleted.
-The 16 most recently deleted frames can be undeleted with 'C-x 5 u' when
-'undelete-frame-mode' is enabled. Without a prefix argument, undelete
-the most recently deleted frame. With a numerical prefix argument
-between 1 and 16, where 1 is the most recently deleted frame, undelete
-the corresponding deleted frame.
-
-** Tab Bars and Tab Lines
-
----
-*** New user option 'tab-bar-auto-width' to automatically determine tab width.
-This option is non-nil by default, which resizes tab-bar tabs so that
-their width is evenly distributed across the tab bar. A companion
-option 'tab-bar-auto-width-max' controls the maximum width of a tab
-before its name on display is truncated.
-
----
-*** 'C-x t RET' creates a new tab when the provided tab name doesn't exist.
-
----
-*** New keymap 'tab-bar-history-mode-map'.
-By default, it contains 'C-c <left>' and 'C-c <right>' to browse
-the history of tab window configurations back and forward.
-
----
-** Better detection of text suspiciously reordered on display.
-The function 'bidi-find-overridden-directionality' has been extended
-to detect reordering effects produced by embeddings and isolates
-(started by directional formatting control characters such as RLO and
-LRI). The new command 'highlight-confusing-reorderings' finds and
-highlights segments of buffer text whose reordering for display is
-suspicious and could be malicious.
-
-** Emacs server and client changes
-
-+++
-*** New command-line option '-r'/'--reuse-frame' for emacsclient.
-With this command-line option, Emacs reuses an existing graphical client
-frame if one exists; otherwise it creates a new frame.
-
-+++
-*** New command-line option '-w N'/'--timeout=N' for emacsclient.
-With this command-line option, emacsclient will exit if Emacs does not
-respond within N seconds. The default is to wait forever.
-
-+++
-*** 'server-stop-automatically' can be used to automatically stop the server.
-The Emacs server will be automatically stopped when certain conditions
-are met. The conditions are given by the argument, which can be
-'empty', 'delete-frame' or 'kill-terminal'.
-
-** Rcirc
-
-+++
-*** New command 'rcirc-when'.
-
-+++
-*** New user option 'rcirc-cycle-completion-flag'.
-Rcirc will use the default 'completion-at-point' mechanism. The
-conventional IRC behavior of completing by cycling through the
-available options can be restored by enabling this option.
-
-+++
-*** New user option 'rcirc-bridge-bot-alist'.
-If you are in a channel where a bot is responsible for bridging
-between networks, you can use this variable to make these messages
-appear more native. For example you might set the option to:
-
- (setq rcirc-bridge-bot-alist '(("bridge" . "{\\(.+?\\)}[[:space:]]+")))
-
-for messages like
-
- 09:47 <bridge> {john} I am not on IRC
-
-to be reformatted into
-
- 09:47 <john> I am not on IRC
-
----
-*** New formatting commands.
-Most IRC clients (including rcirc) support basic formatting using
-control codes. Under the 'C-c C-f' prefix a few commands have been
-added to insert these automatically. For example, if a region is
-active and 'C-c C-f C-b' is invoked, markup is inserted for the region
-to be highlighted bold.
-
-** Imenu
-
-+++
-*** 'imenu' is now bound to 'M-g i' globally.
-
----
-*** New function 'imenu-flush-cache'.
-Use it if you want Imenu to forget the buffer's index alist and
-recreate it anew next time 'imenu' is invoked.
-
-+++
-** Emacs is now capable of abandoning a window's redisplay that takes too long.
-This is controlled by the new variable 'max-redisplay-ticks'. If that
-variable is set to a non-zero value, display of a window will be
-aborted after that many low-level redisplay operations, thus
-preventing Emacs from becoming wedged when visiting files with very
-long lines.
-
-* Editing Changes in Emacs 29.1
-
-+++
-** 'M-SPC' is now bound to 'cycle-spacing'.
-Formerly it invoked 'just-one-space'. The actions performed by
-'cycle-spacing' and their order can now be customized via the user
-option 'cycle-spacing-actions'.
-
----
-** 'zap-to-char' and 'zap-up-to-char' are case-sensitive for upper-case chars.
-These commands now behave as case-sensitive for interactive calls when
-they are invoked with an uppercase character, regardless of the
-'case-fold-search' value.
-
----
-** 'scroll-other-window' and 'scroll-other-window-down' now respect remapping.
-These commands (bound to 'C-M-v' and 'C-M-V') used to scroll the other
-windows without looking a customizations in that other window. These
-functions now check whether they have been rebound in the buffer in
-that other window, and then call the remapped function instead. In
-addition, these commands now also respect the
-'scroll-error-top-bottom' user option.
-
----
-** Indentation of 'cl-flet' and 'cl-labels' has changed.
-These forms now indent like this:
-
- (cl-flet ((bla (x)
- (* x x)))
- (bla 42))
-
-This change also affects 'cl-macrolet', 'cl-flet*' and
-'cl-symbol-macrolet'.
-
-+++
-** New user option 'translate-upper-case-key-bindings'.
-Set this option to nil to inhibit translating upper case keys to lower
-case keys.
-
-+++
-** New command 'ensure-empty-lines'.
-This command increases (or decreases) the number of empty lines before
-point.
-
----
-** Improved mouse behavior with auto-scrolling modes.
-When clicking inside the 'scroll-margin' or 'hscroll-margin' region,
-point is now moved only when releasing the mouse button. This no
-longer results in a bogus selection, unless the mouse has been
-effectively dragged.
-
-+++
-** 'kill-ring-max' now defaults to 120.
-
----
-** New user option 'yank-menu-max-items'.
-Customize this option to limit the number of entries in the menu
-"Edit->Paste from Kill Menu". The default is 60.
-
-+++
-** Performing a pinch gesture on a touchpad now increases the text scale.
-
-** show-paren-mode
-
-+++
-*** New user option 'show-paren-context-when-offscreen'.
-When non-nil, if the point is in a closing delimiter and the opening
-delimiter is offscreen, shows some context around the opening
-delimiter in the echo area. The default is nil.
-
-May also be set to the symbols 'overlay' or 'child-frame', in which
-case the context is shown in an overlay or child-frame at the top-left
-of the current window. The latter option requires a graphical frame.
-On non-graphical frames, the context is shown in the echo area.
-
-** Comint
-
-+++
-*** 'comint-term-environment' is now aware of connection-local variables.
-The user option 'comint-terminfo-terminal' and the variable
-'system-uses-terminfo' can now be set as connection-local variables to
-change the terminal used on a remote host.
-
----
-*** New user option 'comint-delete-old-input'.
-When nil, this prevents comint from deleting the current input when
-inserting previous input using '<mouse-2>'. The default is t, to
-preserve past behavior.
-
----
-*** New minor mode 'comint-fontify-input-mode'.
-This minor mode is enabled by default in "*shell*" and "*ielm*"
-buffers. It fontifies input text according to 'shell-mode' or
-'emacs-lisp-mode' font-lock rules. Customize the user options
-'shell-fontify-input-enable' and 'ielm-fontify-input-enable' to nil if
-you don't want to enable input fontification by default.
-
-** Mwheel
-
----
-*** New user options for alternate wheel events.
-The options 'mouse-wheel-down-alternate-event',
-'mouse-wheel-up-alternate-event', 'mouse-wheel-left-alternate-event',
-and 'mouse-wheel-right-alternate-event' have been added to better
-support systems where two kinds of wheel events can be received.
-
-** Internationalization changes
-
-*** The <Delete> function key now allows deleting the entire composed sequence.
-For the details, see the item about the 'delete-forward-char' command
-above.
-
-*** New user option 'composition-break-at-point'.
-Setting it to a non-nil value temporarily disables automatic
-composition of character sequences at point, and thus makes it easier
-to edit such sequences by allowing point to "enter" the sequence.
-
----
-*** Support for many old scripts and writing systems.
-Emacs now supports and has language-environments and input methods for
-several dozens of old scripts that were used in the past for various
-languages. For each such script Emacs now has font-selection and
-character composition rules, a language environment, and an input
-method. The newly-added scripts and the corresponding language
-environments are:
-

-Coptic script and language environment
-
----
-*** The "Oriya" language environment was renamed to "Odia".
-This is to follow the change in the official name of the script. The
-'oriya' input method was also renamed to 'odia'. However, the old
-name of the language environment and the input method are still
-supported.
-
----
-*** New Greek translation of the Emacs tutorial.
-Type 'C-u C-h t' to select it in case your language setup does not do
-so automatically.
-
----
-*** New Ukrainian translation of the Emacs Tutorial.
-
----
-*** New default phonetic input method for the Tamil language environment.
-The default input method for the Tamil language environment is now
-"tamil-phonetic" which is a customizable phonetic input method. To
-change the input method's translation rules, customize the user option
-'tamil-translation-rules'.
-
----
-*** New tamil99 input method for the Tamil language.
-This supports the keyboard layout specifically designed for the Tamil
-language.
-
----
-*** New input method 'slovak-qwerty'.
-This is a variant of the 'slovak' input method, which corresponds to
-the QWERTY Slovak keyboards.

----
-*** New user option 'ecomplete-filter-regexp'.
-If non-nil, this user option describes what entries not to add to the
-database stored on disk.
-
-** Auth-Source
-
-+++
-*** New user option 'auth-source-pass-extra-query-keywords'.
-Whether to recognize additional keyword params, like ':max' and
-':require', as well as accept lists of query terms paired with
-applicable keywords. This disables most known behavioral quirks
-unique to auth-source-pass, such as wildcard subdomain matching.
-
-** Dired
-
-+++
-*** 'dired-guess-shell-command' moved from dired-x to dired.
-This means that 'dired-do-shell-command' will now provide smarter
-defaults without first having to require 'dired-x'. See the node
-"(emacs) Shell Command Guessing" in the Emacs manual for more details.
-
----
-*** 'dired-clean-up-buffers-too' moved from dired-x to dired.
-This means that Dired now offers to kill buffers visiting files and
-dirs when they are deleted in Dired. Before, you had to require
-'dired-x' to enable this behavior. To disable this behavior,
-customize the user option 'dired-clean-up-buffers-too' to nil. The
-related user option 'dired-clean-confirm-killing-deleted-buffers'
-(which see) has also been moved to 'dired'.
-
-+++
-*** 'dired-do-relsymlink' moved from dired-x to dired.
-The corresponding key 'Y' is now bound by default in Dired.
-
-+++
-*** 'dired-do-relsymlink-regexp' moved from dired-x to dired.
-The corresponding key '% Y' is now bound by default in Dired.
-
----
-*** 'M-G' is now bound to 'dired-goto-subdir'.
-Before, that binding was only available if the dired-x package was
-loaded.
-
-+++
-*** 'dired-info' and 'dired-man' moved from dired-x to dired.
-The 'dired-info' and 'dired-man' commands have been moved from the
-dired-x package to dired. They have also been renamed to
-'dired-do-info' and 'dired-do-man'; the old command names are obsolete
-aliases.
-
-The keys 'I' ('dired-do-info') and 'N' ('dired-do-man') are now bound
-in Dired mode by default. The user options 'dired-bind-man' and
-'dired-bind-info' no longer have any effect and are obsolete.
-
-To get the old behavior back and unbind these keys in Dired mode, add
-the following to your Init file:
-
- (with-eval-after-load 'dired
- (keymap-set dired-mode-map "N" nil)
- (keymap-set dired-mode-map "I" nil))
-

-byte-compile the visited file and the current buffer, respectively.
-
-** Games
-
----
-*** New user option 'tetris-allow-repetitions'.
-This controls how randomness is implemented (whether to use pure
-randomness as before or whether to use a bag).
-
-** Battery
-
-+++
-*** New user option 'battery-update-functions'.
-This can be used to trigger actions based on the battery status.
-
-** Enriched Mode
-
-+++
-*** New command 'enriched-toggle-markup'.
-This allows you to see the markup in 'enriched-mode' buffers (e.g.,
-the "HELLO" file).
-
-** Shell Script Mode
-
----
-*** New user option 'sh-indent-statement-after-and'.
-This controls how statements like the following are indented:
-
- foo &&
- bar
-
-*** New Flymake backend using the ShellCheck program.
-It is enabled by default, but requires that the external "shellcheck"
-command is installed.
-
-** CC Mode
-
----
-*** C++ Mode now supports most of the new features in the C++20 standard.
-
-** Cperl Mode
-

-the run/continue command.
-
----

-all optional features of the Perl version in use. 'perldb' now uses
-this invocation as its default.
-
-** Customize
-
----
-*** New command 'custom-toggle-hide-all-widgets'.
-This is bound to 'H' and toggles whether to hide or show the widget
-contents.
-
-** Diff mode
-
----
-*** New user option 'diff-whitespace-style'.
-Sets the value of the buffer-local variable 'whitespace-style' in
-'diff-mode' buffers. By default, this variable is '(face trailing)',
-which preserves behavior from previous Emacs versions.
-
-+++
-*** New user option 'diff-add-log-use-relative-names'.
-If non-nil insert file names in ChangeLog skeletons relative to the
-VC root directory.
-
-** Ispell
-
----
-*** 'ispell-region' and 'ispell-buffer' now push the mark.
-These commands push onto the mark ring the location of the last
-misspelled word where corrections were offered, so that you can then
-skip back to that location with 'C-x C-x'.
-
-** Dabbrev
-
----
-*** New function 'dabbrev-capf' for use on 'completion-at-point-functions'.
-
-+++
-*** New user option 'dabbrev-ignored-buffer-modes'.
-Buffers with major modes in this list will be ignored. By default,
-this includes "binary" buffers like 'archive-mode' and 'image-mode'.
-
-** Package
-
-+++
-*** New command 'package-update'.
-This command allows you to upgrade packages without using 'M-x
-list-packages'.
-
-+++
-*** New command 'package-update-all'.
-This command allows updating all packages without any queries.
-
-+++
-*** New commands 'package-recompile' and 'package-recompile-all'.
-These commands can be useful if the ".elc" files are out of date
-(invalid byte code and macros).
-
-+++
-*** New DWIM action on 'x' in "*Packages*" buffer.
-If no packages are marked, 'x' will install the package under point if
-it isn't already, and remove it if it is installed.
-
-+++
-*** New command 'package-vc-install'.
-Packages can now be installed directly from source by cloning from a
-repository.
-
-+++
-*** New command 'package-vc-install-from-checkout'.
-An existing checkout can now be loaded via package.el, by creating a
-symbolic link from the usual package directory to the checkout.
-
-+++
-*** New command 'package-vc-checkout'.
-Used to fetch the source of a package by cloning a repository without
-activating the package.
-
-+++
-*** New command 'package-vc-prepare-patch'.
-This command allows you to send patches to package maintainers, for
-packages checked out using 'package-vc-install'.
-
-+++
-*** New command 'package-report-bug'.
-This command helps you compose an email for sending bug reports to
-package maintainers.
-
-+++
-*** New user option 'package-vc-selected-packages'.
-By customizing this user option you can specify specific packages to
-install.
-
-** Emacs Sessions (Desktop)
-
-+++
-*** New user option to load a locked desktop if locking Emacs is not running.
-The option 'desktop-load-locked-desktop' can now be set to the value
-'check-pid', which means to allow loading a locked ".emacs.desktop"
-file if the Emacs process which locked it is no longer running on the
-local machine. This allows avoiding questions about locked desktop
-files when the Emacs session which locked it crashes, or was otherwise
-interrupted, and didn't exit gracefully. See the "(emacs) Saving
-Emacs Sessions" node in the Emacs manual for more details.
-
-** Miscellaneous
-
-+++
-*** New command 'scratch-buffer'.
-This command switches to the "*scratch*" buffer. If "*scratch*" doesn't
-exist, the command creates it first. You can use this command if you
-inadvertently delete the "*scratch*" buffer.
-
-** Debugging
-
----
-*** 'q' in a "*Backtrace*" buffer no longer clears the buffer.
-Instead it just buries the buffer and switches the mode from
-'debugger-mode' to 'backtrace-mode', since commands like 'e' are no
-longer available after exiting the recursive edit.
-
-+++
-*** New user option 'debug-allow-recursive-debug'.
-This user option controls whether the 'e' (in a "*Backtrace*"
-buffer or while edebugging) and 'C-x C-e' (while edebugging) commands
-lead to a (further) backtrace. By default, this variable is nil,
-which is a change in behavior from previous Emacs versions.
-
-+++
-*** 'e' in edebug can now take a prefix arg to pretty-print the results.
-When invoked with a prefix argument, as in 'C-u e', this command will
-pop up a new buffer and show the full pretty-printed value there.
-
-+++
-*** 'C-x C-e' now interprets a non-zero prefix arg to pretty-print the results.
-When invoked with a non-zero prefix argument, as in 'C-u C-x C-e',
-this command will pop up a new buffer and show the full pretty-printed
-value there.
-
-+++
-*** You can now generate a backtrace from Lisp errors in redisplay.
-To do this, set the new variable 'backtrace-on-redisplay-error' to a
-non-nil value. The backtrace will be written to a special buffer
-named "*Redisplay-trace*". This buffer will not be automatically
-displayed in a window.
-
-** Compile
-
-+++
-*** New user option 'compilation-hidden-output'.
-This can be used to make specific parts of compilation output
-invisible.
-
-+++
-*** The 'compilation-auto-jump-to-first-error' user option has been extended.
-It can now have the additional values 'if-location-known' (which will
-only jump if the location of the first error is known), and
-'first-known' (which will jump to the first known error location).
-
-+++
-*** New user option 'compilation-max-output-line-length'.
-Lines longer than this will have the ends hidden, with a button to
-reveal the hidden text. This speeds up operations like grepping on
-files that have few newlines.
-
-** Flymake
-
-+++
-*** New user option 'flymake-mode-line-lighter'.
-
-+++
-** New minor mode 'word-wrap-whitespace-mode' for extending 'word-wrap'.
-This mode switches 'word-wrap' on, and breaks on all the whitespace
-characters instead of just 'SPC' and 'TAB'.
-
----
-** New mode, 'emacs-news-mode', for editing the NEWS file.
-This mode adds some highlighting, fixes the 'M-q' command, and has
-commands for doing maintenance of the Emacs NEWS files. In addition,
-this mode turns on 'outline-minor-mode', and thus displays
-customizable icons (see 'icon-preference') in the margins. To
-disable these icons, set 'outline-minor-mode-use-buttons' to a
-nil value.
-
----
-** Kmacro
-Kmacros are now OClosures and have a new constructor 'kmacro' which
-uses the 'key-parse' syntax. It replaces the old 'kmacro-lambda-form'
-(which is now declared obsolete).
-
----
-** savehist.el can now truncate variables that are too long.
-An element of 'savehist-additional-variables' can now be of the form
-'(VARIABLE . MAX-ELTS)', which means to truncate the VARIABLE's value to
-at most MAX-ELTS elements (if the value is a list) before saving the
-value.
-
-** Minibuffer and Completions
-
-+++
-*** New commands for navigating completions from the minibuffer.
-When the minibuffer is the current buffer, typing 'M-<up>' or
-'M-<down>' selects a previous/next completion candidate from the
-"*Completions*" buffer and inserts it to the minibuffer.
-When the user option 'minibuffer-completion-auto-choose' is nil,
-'M-<up>' and 'M-<down>' do the same, but without inserting
-a completion candidate to the minibuffer, then 'M-RET' can be used
-to choose the currently active candidate from the "*Completions*"
-buffer and exit the minibuffer. With a prefix argument, 'C-u M-RET'
-inserts the currently active candidate to the minibuffer, but doesn't
-exit the minibuffer. These keys are also available for in-buffer
-completion, but they don't insert candidates automatically, you need
-to type 'M-RET' to insert the selected candidate to the buffer.
-
-+++
-*** The "*Completions*" buffer can now be automatically selected.
-To enable this behavior, customize the user option
-'completion-auto-select' to t, then pressing 'TAB' will switch to the
-"*Completions*" buffer when it pops up that buffer. If the value is
-'second-tab', then the first 'TAB' will display "*Completions*", and
-the second one will switch to the "*Completions*" buffer.
-
----
-*** New user option 'completion-auto-wrap'.
-When non-nil, the commands 'next-completion', 'previous-completion',
-'next-line-completion' and 'previous-line-completion' automatically
-wrap around on reaching the beginning or the end of the "*Completions*"
-buffer.
-
-+++
-*** New values for the 'completion-auto-help' user option.
-There are two new values to control the way the "*Completions*" buffer
-behaves after pressing a 'TAB' if completion is not unique. The value
-'always' updates or shows the "*Completions*" buffer after any attempt
-to complete. The value 'visual' is like 'always', but only updates
-the completions if they are already visible. The default value t
-always hides the completion buffer after some completion is made.
-
-*** New commands to complete the minibuffer history.
-'minibuffer-complete-history' ('C-x <up>') is like 'minibuffer-complete'
-but completes on the history items instead of the default completion
-table. 'minibuffer-complete-defaults' ('C-x <down>') completes
-on the list of default items.
-
-+++
-*** User option 'minibuffer-eldef-shorten-default' is now obsolete.
-Customize the user option 'minibuffer-default-prompt-format' instead.
-
-+++
-*** New user option 'completions-sort'.
-This option controls the sorting of the completion candidates in
-the "*Completions*" buffer. Available styles are no sorting,
-alphabetical (the default), or a custom sort function.
-
-+++
-*** New user option 'completions-max-height'.
-This option limits the height of the "*Completions*" buffer.
-
-+++
-*** New user option 'completions-header-format'.
-This is a string to control the heading line to show in the
-"*Completions*" buffer before the list of completions.
-If it contains "%s", that is replaced with the number of completions.
-If nil, the heading line is not shown.
-
-+++
-*** New user option 'completions-highlight-face'.
-When this user option names a face, the current
-candidate in the "*Completions*" buffer is highlighted with that face.
-The nil value disables this highlighting.
-
-+++
-*** Choosing a completion with a prefix argument doesn't exit the minibuffer.
-This means that typing 'C-u RET' on a completion candidate in the
-"*Completions*" buffer inserts the completion to the minibuffer,
-but doesn't exit the minibuffer.
-
-+++
-*** You can now define abbrevs for the fundamental minibuffer modes.
-'minibuffer-mode-abbrev-table' and
-'minibuffer-inactive-mode-abbrev-table' are now defined.
-
-** Isearch and Replace
-
-+++
-*** Changes in how Isearch responds to 'mouse-yank-at-point'.
-If a user does 'C-s' and then uses '<mouse-2>' ('mouse-yank-primary')
-outside the echo area, Emacs will, by default, end the Isearch and
-yank the text at mouse cursor. But if 'mouse-yank-at-point' is
-non-nil, the text will now be added to the Isearch instead.
-
-+++
-*** Changes for values 'no' and 'no-ding' of 'isearch-wrap-pause'.
-Now with these values the search will wrap around not only on repeating
-with 'C-s C-s', but also after typing a character.
-
-+++
-*** New user option 'char-fold-override'.
-Non-nil means that the default definitions of equivalent characters
-are overridden.
-
-*** New command 'describe-char-fold-equivalences'.
-It displays character equivalences used by 'char-fold-to-regexp'.
-
-+++
-*** New command 'isearch-emoji-by-name'.
-It is bound to 'C-x 8 e RET' during an incremental search. The
-command accepts the Unicode name of an Emoji (for example, "smiling
-face" or "heart with arrow"), like 'C-x 8 e e', with minibuffer
-completion, and adds the Emoji into the search string.
-
-** Glyphless characters
-
-+++
-*** New minor mode 'glyphless-display-mode'.
-This allows an easy way to toggle seeing all glyphless characters in
-the current buffer.
-
----
-*** The extra slot of 'glyphless-char-display' can now have cons values.
-The extra slot of the 'glyphless-char-display' char-table can now have
-values that are cons cells, specifying separate values for text-mode
-and GUI terminals.
-
-+++
-*** "Replacement character" feature for undisplayable characters on TTYs.
-The 'acronym' method of displaying glyphless characters on text-mode
-frames treats single-character acronyms specially: they are displayed
-without the surrounding [..] "box", thus in effect treating such
-"acronyms" as replacement characters.
-
-** Registers
-
-+++
-*** Buffer names can now be stored in registers.
-For instance, to enable jumping to the "*Messages*" buffer with
-'C-x r j m':
-
- (set-register ?m '(buffer . "*Messages*"))
-
-** Pixel-fill
-
-+++
-*** This is a new package that deals with filling variable-pitch text.
-
-+++
-*** New function 'pixel-fill-region'.
-This fills the region to be no wider than a specified pixel width.
-
-** Info
-
-+++
-*** 'M-x info-apropos' now takes a prefix argument to search for regexps.
-
----
-*** New command 'Info-goto-node-web' and key binding 'G'.
-This will take you to the gnu.org web server's version of the current
-info node. This command only works for the Emacs and Emacs Lisp manuals.
-
-** Shortdoc
-
----
-*** New command 'shortdoc-copy-function-as-kill' bound to 'w'.
-It copies the name of the function near point into the kill ring.
-
----
-*** 'N' and 'P' are now bound to 'shortdoc-{next,previous}-section'.
-This is in addition to the old keybindings 'C-c C-n' and 'C-c C-p'.
-
-** VC
-
----
-*** New command 'vc-pull-and-push'.
-This commands first does a "pull" command, and if that is successful,
-do a "push" command afterwards.
-
-+++
-*** 'C-x v b' prefix key is used now for branch commands.
-'vc-print-branch-log' is bound to 'C-x v b l', and new commands are
-'vc-create-branch' ('C-x v b c') and 'vc-switch-branch' ('C-x v b s').
-The VC Directory buffer now uses the prefix 'b' for these branch-related
-commands.
-
-+++
-*** New command '%' ('vc-dir-mark-by-regexp').
-This command marks files based on a regexp. If given a prefix
-argument, unmark instead.
-
-+++
-*** New command 'C-x v !' ('vc-edit-next-command').
-This prefix command requests editing of the next VC shell command
-before execution. For example, in a Git repository, you can produce a
-log of more than one branch by typing 'C-x v ! C-x v b l' and then
-appending additional branch names to the 'git log' command.
-
----
-*** 'C-x v v' in a diffs buffer allows to commit only some of the changes.
-This command is intended to allow you to commit only some of the
-changes you have in your working tree. Begin by creating a buffer
-with the changes against the last commit, e.g. with 'C-x v D'
-('vc-root-diff'). Then edit the diffs to remove the hunks you don't
-want to commit. Finally, type 'C-x v v' in that diff buffer to commit
-only part of your changes, those whose hunks were left in the buffer.
-
----
-*** 'C-x v v' on an unregistered file will now use the most specific backend.
-Previously, if you had an SVN-covered "~/" directory, and a Git-covered
-directory in "~/foo/bar", using 'C-x v v' on a new, unregistered file
-"~/foo/bar/zot" would register it in the SVN repository in "~/" instead of
-in the Git repository in "~/foo/bar". This makes this command
-consistent with 'vc-responsible-backend'.
-
----
-*** Log Edit now font locks long Git commit summary lines.
-Writing shorter summary lines avoids truncation in contexts in which
-Git commands display summary lines. See the two new user options
-'vc-git-log-edit-summary-target-len' and 'vc-git-log-edit-summary-max-len'.
-
----
-*** New 'log-edit-headers-separator' face.
-It is used to style the line that separates the 'log-edit' headers
-from the 'log-edit' summary.
-
----
-*** The function 'vc-read-revision' accepts a new MULTIPLE argument.
-If non-nil, multiple revisions can be queried. This is done using
-'completing-read-multiple'.
-
----
-*** New function 'vc-read-multiple-revisions'.
-This function invokes 'vc-read-revision' with a non-nil value for
-MULTIPLE.
-
-+++
-*** New command 'vc-prepare-patch'.
-Patches for any version control system can be prepared using VC. The
-command will query what commits to send and will compose messages for
-your mail user agent. The behavior of 'vc-prepare-patch' can be
-modified by the user options 'vc-prepare-patches-separately' and
-'vc-default-patch-addressee'.
-
-** Message
-
----
-*** New user option 'mml-attach-file-at-the-end'.
-If non-nil, 'C-c C-a' will put attached files at the end of the message.
-
----
-*** Message Mode now supports image yanking.
-
-+++
-*** New user option 'message-server-alist'.
-This controls automatic insertion of the "X-Message-SMTP-Method"
-header before sending a message.
-
-** HTML Mode
-
----
-*** HTML Mode now supports "text/html" and "image/*" yanking.
-
-** Texinfo Mode
-
----
-*** 'texinfo-mode' now has a specialized 'narrow-to-defun' definition.
-It narrows to the current node.
-
-** EUDC
-
-+++
-*** New user option 'eudc-ignore-options-file' that defaults to nil.
-The 'eudc-ignore-options-file' user option can be configured to ignore
-the 'eudc-options-file' (typically "~/.emacs.d/eudc-options"). Most
-users should configure this to t and put EUDC configuration in the
-main Emacs initialization file ("~/.emacs" or "~/.emacs.d/init.el").
-
-+++
-*** 'eudc-expansion-overwrites-query' to 'eudc-expansion-save-query-as-kill'.
-'eudc-expansion-overwrites-query' is renamed to
-'eudc-expansion-save-query-as-kill' to reflect the actual behavior of
-the user option.
-
-+++
-*** New command 'eudc-expand-try-all'.
-This command can be used in place of 'eudc-expand-inline'. It takes a
-prefix argument that causes 'eudc-expand-try-all' to return matches
-from all servers instead of just the matches from the first server to
-return any. This is useful for example, if one wants to search LDAP
-for a name that happens to match a contact in one's BBDB.
-
-+++
-*** New behavior and default for user option 'eudc-inline-expansion-format'.
-EUDC inline expansion result formatting defaulted to
-
- '("%s %s <%s>" firstname name email)
-
-Since email address specifications need to comply with RFC 5322 in
-order to be useful in messages, there was a risk to produce syntax
-which was standard with RFC 822, but is marked as obsolete syntax by
-its successor RFC 5322. Also, the first and last name part was never
-enclosed in double quotes, potentially producing invalid address
-specifications, which may be rejected by a receiving MTA. Thus, this
-variable can now additionally be set to nil (the new default), or a
-function. In both cases, the formatted result will be in compliance
-with RFC 5322. When set to nil, a default format very similar to the
-old default will be produced. When set to a function, that function
-is called, and the returned values are used to populate the phrase and
-comment parts (see RFC 5322 for definitions). In both cases, the
-phrase part will be automatically quoted if necessary.
-
-+++
-*** New function 'eudc-capf-complete' with 'message-mode' integration.
-EUDC can now contribute email addresses to 'completion-at-point' by
-adding the new function 'eudc-capf-complete' to
-'completion-at-point-functions' in 'message-mode'.
-
-+++
-*** Additional attributes of query and results in eudcb-macos-contacts.el.
-The EUDC back-end for the macOS Contacts app now provides a wider set
-of attributes to use for queries, and delivers more attributes in
-query results.
-
-+++
-*** New back-end for ecomplete.
-A new back-end for ecomplete allows information from that database to
-be queried by EUDC, too. The attributes present in the EUDC query are
-used to select the entry type in the ecomplete database.
-
-+++
-*** New back-end for mailabbrev.
-A new back-end for mailabbrev allows information from that database to
-be queried by EUDC, too. The attributes 'email', 'name', and 'firstname'
-are supported only.
-
-** EWW/SHR
-
-+++
-*** New user option to automatically rename EWW buffers.
-The 'eww-auto-rename-buffer' user option can be configured to rename
-rendered web pages by using their title, URL, or a user-defined
-function which returns a string. For the first two cases, the length
-of the resulting name is controlled by 'eww-buffer-name-length'. By
-default, no automatic renaming is performed.
-
-+++
-*** New user option 'shr-allowed-images'.
-This complements 'shr-blocked-images', but allows specifying just the
-allowed images.
-
-+++
-*** New user option 'shr-use-xwidgets-for-media'.
-If non-nil (and Emacs has been built with support for xwidgets),
-display <video> elements with an xwidget. Note that this is
-experimental; it is known to crash Emacs on some systems, and just
-doesn't work on other systems. Also see etc/PROBLEMS.
-
-+++
-*** New user option 'eww-url-transformers'.
-These are used to alter an URL before using it. By default it removes
-the common "utm_" trackers from URLs.
-
-** Find-Dired
-
----
-*** New command 'find-dired-with-command'.
-This enables users to run 'find-dired' with an arbitrary command,
-enabling running commands previously unsupported and also enabling new
-commands to be built on top.
-
-** Gnus
-
-+++
-*** Tool bar changes in Gnus/Message.
-There were previously two styles of tool bars available in Gnus and
-Message, referred to as 'gnus-summary-tool-bar-retro',
-'gnus-group-tool-bar-retro' and 'message-tool-bar-retro', and
-'gnus-summary-tool-bar-gnome', 'gnus-group-tool-bar-gnome' and
-'message-tool-bar-gnome'. The "retro" tool bars have been removed (as
-well as the icons used), and the "Gnome" tool bars are now the only
-pre-defined toolbars.
-
----
-*** 'gnus-summary-up-thread' and 'gnus-summary-down-thread' bindings removed.
-The 'gnus-summary-down-thread' binding to "M-C-d" was shadowed by
-'gnus-summary-read-document', and these commands are also available on
-"T-u" and "T-d" respectively.
-
----
-*** Gnus now uses a variable-pitch font in the headers by default.
-To get the monospace font back, you can put something like the
-following in your ".gnus" file:
-
- (set-face-attribute 'gnus-header nil :inherit 'unspecified)
-
----
-*** The default value of 'gnus-treat-fold-headers' is now 'head'.
-
----
-*** New face 'gnus-header'.
-All other 'gnus-header-*' faces inherit from this face now.
-
-+++
-*** New user option 'gnus-treat-emojize-symbols'.
-If non-nil, symbols that have an emoji representation will be
-displayed as emojis. The default is nil.
-
-+++
-*** New command 'gnus-article-emojize-symbols'.
-This is bound to 'W D e' and will display symbols that have emoji
-representation as emojis.
-
-+++
-*** New mu backend for gnus-search.
-Configuration is very similar to the notmuch and namazu backends. It
-supports the unified search syntax.
-
----
-*** 'gnus-html-image-cache-ttl' is now a seconds count.
-Formerly it was a pair of numbers '(A B)' that represented 65536*A + B,
-to cater to older Emacs implementations that lacked bignums.
-The older form still works but is undocumented.
-
-** Rmail
-
----
-*** Rmail partial summaries can now be applied one on top of the other.
-You can now narrow the set of messages selected by Rmail summary's
-criteria (recipients, topic, senders, etc.) by making a summary of the
-already summarized messages. For example, invoking
-'rmail-summary-by-senders', followed by 'rmail-summary-by-topic' will
-produce a summary where both the senders and the topic are according
-to your selection. The new user option
-'rmail-summary-progressively-narrow' controls whether the stacking of
-the filters is in effect; customize it to a non-nil value to enable
-this feature.
-
----
-*** New Rmail summary: by thread.
-The new command 'rmail-summary-by-thread' produces a summary of
-messages that belong to a single thread of discussion.
-
-** EIEIO
-
-+++
-*** 'slot-value' can now be used to access slots of 'cl-defstruct' objects.
-
-** Align
-
----
-*** Alignment in 'text-mode' has changed.
-Previously, 'M-x align' didn't do anything, and you had to say 'C-u
-M-x align' for it to work. This has now been changed. The default
-regexp for 'C-u M-x align-regexp' has also been changed to be easier
-for inexperienced users to use.
-
-** Help
-
----
-*** New mode, 'emacs-news-view-mode', for viewing the NEWS file.
-This mode is used by the 'C-h N' command, and adds buttons to manual
-entries and symbol references.
-
----
-*** New user option 'help-link-key-to-documentation'.
-When this option is non-nil (which is the default), key bindings
-displayed in the "*Help*" buffer will be linked to the documentation
-for the command they are bound to. This does not affect listings of
-key bindings and functions (such as 'C-h b').
-
-** Info-look
-
----
-*** info-look specs can now be expanded at run time instead of a load time.
-The new ':doc-spec-function' element can be used to compute the
-':doc-spec' element when the user asks for info on that particular
-mode (instead of at load time).
-
-** Ansi-color
-
----
-*** Support for ANSI 256-color and 24-bit colors.
-256-color and 24-bit color codes are now handled by ANSI color
-filters and displayed with the specified color.
-
-** Term-mode
-
----
-*** New user option 'term-bind-function-keys'.
-If non-nil, 'term-mode' will pass the function keys on to the
-underlying shell instead of using the normal Emacs bindings.
-
----
-*** Support for ANSI 256-color and 24-bit colors, italic and other fonts.
-'term-mode' can now display 256-color and 24-bit color codes. It can
-also handle ANSI codes for faint, italic and blinking text, displaying
-it with new 'term-{faint,italic,slow-blink,fast-blink}' faces.
-
-** Xref
-
-+++
-*** 'project-find-file' and 'project-or-external-find-file' now accept
-a prefix argument which is interpreted to mean "include all files".
-
-+++
-*** New command 'project-list-buffers' bound to 'C-x p C-b'.
-This command displays a list of buffers from the current project.
-
-+++
-*** 'project-kill-buffers' can display the list of buffers to kill.
-Customize the user option 'project-kill-buffers-display-buffer-list'
-to enable the display of the buffer list.
-
-+++
-*** New command 'xref-go-forward'.
-It is bound to 'C-M-,' and jumps to the location where 'xref-go-back'
-('M-,', also known as 'xref-pop-marker-stack') was invoked previously.
-
-+++
-*** 'xref-query-replace-in-results' prompting change.
-This command no longer prompts for FROM when called without prefix
-argument. This makes the most common case faster: replacing entire
-matches.
-
-+++
-*** New command 'xref-find-references-and-replace' to rename one identifier.
-
----
-*** New variable 'xref-current-item' (renamed from a private version).
-
----
-*** New function 'xref-show-xrefs'.
-
-** File notifications
-
-+++
-*** The new command 'file-notify-rm-all-watches' removes all file
notifications.
-
-** Sql
-
----
-*** Sql now supports sending of passwords in-process.
-To improve security, if an sql product has ':password-in-comint' set
-to t, a password supplied via the minibuffer will be sent in-process,
-as opposed to via the command-line.
-
-** Image Mode
-
-+++
-*** New command 'image-transform-fit-to-window'.
-This command fits the image to the current window by scaling down or
-up as necessary. Unlike 'image-transform-fit-both', this does not
-only scale the image down, but up as well. It is bound to 's w' in
-Image Mode by default.
-
----
-*** New command 'image-mode-wallpaper-set'.
-This command sets the desktop background to the current image. It is
-bound to 'W' by default.
-
-+++
-*** 'image-transform-fit-to-{height,width}' are now obsolete.
-Use the new command 'image-transform-fit-to-window' instead.
-The keybinding for 'image-transform-fit-to-width' is now 's i'.
-
----
-*** User option 'image-auto-resize' can now be set to 'fit-window'.
-This works like 'image-transform-fit-to-window'.
-
----
-*** New user option 'image-auto-resize-max-scale-percent'.
-The new 'fit-window' option will never scale an image more than this
-much (in percent). It is nil by default, which means no limit.
-
----
-*** New user option 'image-text-based-formats'.
-This controls whether or not to show a message when opening certain
-image formats saying how to edit it as text. The default is to show
-this message for SVG and XPM.
-
-+++
-*** New commands: 'image-flip-horizontally' and 'image-flip-vertically'.
-These commands horizontally and vertically flip the image under point,
-and are bound to 'i h' and 'i v', respectively.
-
-+++

-It allows setting the image size to a percentage of its original size,
-and is bound to 's p' in Image mode.
-
-+++
-*** 'image-transform-original' renamed to 'image-transform-reset-to-original'.
-The old name was confusing, and is now an obsolete function alias.
-
-+++
-*** 'image-transform-reset' renamed to 'image-transform-reset-to-initial'.
-The old name was confusing, and is now an obsolete function alias.
-
-** Images
-
-+++
-*** Users can now add special image conversion functions.
-This is done via 'image-converter-add-handler'.
-
-** Image-Dired
-
-+++
-*** 'image-dired-image-mode' is now based on 'image-mode'.
-This avoids converting images in the background, and makes Image-Dired
-noticeably faster. New keybindings from 'image-mode' are now
-available in the "*image-dired-display-image*" buffer; press '?' or
-'h' in that buffer to see the full list.
-
----
-*** Navigation and marking commands now work in image display buffer.
-The following new bindings have been added:
-- 'n', 'SPC' => 'image-dired-display-next'
-- 'p', 'DEL' => 'image-dired-display-previous'
-- 'm' => 'image-dired-mark-thumb-original-file'
-- 'd' => 'image-dired-flag-thumb-original-file'
-- 'u' => 'image-dired-unmark-thumb-original-file'
-
----
-*** New command 'image-dired-unmark-all-marks'.
-It removes all marks from all files in the thumbnail and the
-associated Dired buffer, and is bound to 'U' in the thumbnail and
-display buffer.
-
----
-*** New command 'image-dired-do-flagged-delete'.
-It deletes all flagged files, and is bound to 'x' in the thumbnail
-buffer. It replaces the command 'image-dired-delete-marked', which is
-now an obsolete alias.
-
----
-*** New command 'image-dired-copy-filename-as-kill'.
-It copies the name of the marked or current image to the kill ring,
-and is bound to 'w' in the thumbnail buffer.
-
----
-*** New command 'image-dired-wallpaper-set'.
-This command sets the desktop background to the image at point in the
-thumbnail buffer. It is bound to 'W' by default.
-
----
-*** 'image-dired-slideshow-start' is now bound to 'S'.
-It is bound in both the thumbnail and display buffer, and no longer
-prompts for a timeout; use a numerical prefix (e.g. 'C-u 8 S') to set
-the timeout.
-
----
-*** New user option 'image-dired-marking-shows-next'.
-If this option is non-nil (the default), marking, unmarking or
-flagging an image in either the thumbnail or display buffer shows the
-next image.
-
----
-*** New face 'image-dired-thumb-flagged'.
-If 'image-dired-thumb-mark' is non-nil (the default), this face is
-used for images that are flagged for deletion in the Dired buffer
-associated with Image-Dired.
-
----
-*** Image information is now shown in the header line of the thumbnail buffer.
-This replaces the message that most navigation commands in the
-thumbnail buffer used to show at the bottom of the screen.
-
----
-*** New specifiers for 'image-dired-display-properties-format'.
-This is used to format the new header line. The new specifiers are:
-"%d" for the name of the directory that the file is in, "%n" for
-file's number in the thumbnail buffer, and "%s" for the file size.
-
-The default format has been updated to use this. If you prefer the
-old format, add this to your Init file:
-
- (setopt image-dired-display-properties-format "%b: %f (%t): %c")
-
----
-*** New faces for the header line of the thumbnail buffer.
-These faces correspond to different parts of the header line, as
-specified in 'image-dired-display-properties-format':
-- 'image-dired-thumb-header-directory-name'
-- 'image-dired-thumb-header-file-name'
-- 'image-dired-thumb-header-file-size'
-- 'image-dired-thumb-header-image-count'
-
----
-*** PDF support.
-Image-Dired now displays thumbnails for PDF files. Type 'RET' on a
-PDF file in the thumbnail buffer to visit the corresponding PDF.
-
----
-*** Support GraphicsMagick command line tools.
-Support for the GraphicsMagick command line tool ("gm") has been
-added, and is used instead of ImageMagick when it is available.
-
----
-*** Support Thumbnail Managing Standard v0.9.0 (Dec 2020).
-This standard allows sharing generated thumbnails across different
-programs. Version 0.9.0 adds two larger thumbnail sizes: 512x512 and
-1024x1024 pixels. See the user option 'image-dired-thumbnail-storage'
-to use it; it is not enabled by default.
-
----
-*** Reduce dependency on external "exiftool" command.
-The 'image-dired-copy-with-exif-file-name' no longer requires an
-external "exiftool" command to be available. The user options
-'image-dired-cmd-read-exif-data-program' and
-'image-dired-cmd-read-exif-data-options' are now obsolete.
-
----
-*** Support for bookmark.el.
-The command 'bookmark-set' (bound to 'C-x r m') is now supported in
-the thumbnail view, and will create a bookmark that opens the current
-directory in Image-Dired.
-
----
-*** The 'image-dired-slideshow-start' command no longer prompts.
-It no longer inconveniently prompts for a number of images and a
-delay: it runs indefinitely, but stops automatically on any command.
-You can set the delay with a prefix argument, or a negative prefix
-argument to prompt for a delay. Customize the user option
-'image-dired-slideshow-delay' to change the default from 5 seconds.
-
-+++
-*** 'image-dired-show-all-from-dir-max-files' increased to 1000.
-This user option controls asking for confirmation when starting
-Image-Dired in a directory with many files. Since Image-Dired creates
-thumbnails in the background in recent versions, this is not as
-important as it used to be. You can now also customize this option to
-nil to disable this confirmation completely.
-
----
-*** 'image-dired-thumb-size' increased to 128.
-
-+++
-*** 'image-dired-db-file' renamed to 'image-dired-tags-db-file'.
-
----
-*** 'image-dired-display-image-mode' renamed to 'image-dired-image-mode'.
-The corresponding keymap is now named 'image-dired-image-mode-map'.
-
-+++
-*** Some commands have been renamed to be shorter.
-- 'image-dired-display-thumbnail-original-image' has been renamed to
- 'image-dired-display-this'.
-- 'image-dired-display-next-thumbnail-original' has been renamed to
- 'image-dired-display-next'.
-- 'image-dired-display-previous-thumbnail-original' has been renamed
- to 'image-dired-display-previous'.
-The old names are now obsolete aliases.
-
----
-*** 'image-dired-thumb-{height,width}' are now obsolete.
-Customize 'image-dired-thumb-size' instead, which will set both the
-height and width.
-
----
-*** HTML image gallery generation is now obsolete.
-The 'image-dired-gallery-generate' command and these user options are
-now obsolete: 'image-dired-gallery-thumb-image-root-url',
-'image-dired-gallery-hidden-tags', 'image-dired-gallery-dir',
-'image-dired-gallery-image-root-url'.
-
----
-*** 'image-dired-rotate-thumbnail-{left,right}' are now obsolete.
-Instead, use commands 'image-dired-refresh-thumb' to generate a new
-thumbnail, or 'image-rotate' to rotate the thumbnail without updating
-the thumbnail file.
-
-+++
-*** Some commands and user options are now obsolete.
-Since 'image-dired-display-image-mode' is now based on 'image-mode',
-some commands and user options are no longer needed and are now obsolete:
-'image-dired-cmd-create-temp-image-options',
-'image-dired-cmd-create-temp-image-program',
-'image-dired-display-current-image-full',
-'image-dired-display-current-image-sized',
-'image-dired-display-window-height-correction',
-'image-dired-display-window-width-correction',
-'image-dired-temp-image-file'.
-
-** Dired
-
----
-*** New user option 'dired-omit-lines'.
-This is used by 'dired-omit-mode', and now allows you to hide based on
-other things than just the file names.
-
-+++
-*** New user option 'dired-mouse-drag-files'.
-If non-nil, dragging file names with the mouse in a Dired buffer will
-initiate a drag-and-drop session allowing them to be opened in other
-programs.
-
-+++
-*** New user option 'dired-free-space'.
-Dired will now, by default, include the free space in the first line
-instead of having it on a separate line. To get the previous behavior
-back, say:
-
- (setq dired-free-space 'separate)
-
----
-*** New user option 'dired-make-directory-clickable'.
-If non-nil (which is the default), hitting 'RET' or 'mouse-1' on
-the directory components at the directory displayed at the start of
-the buffer will take you to that directory.
-
----
-*** Search and replace in Dired/Wdired supports more regexps.
-For example, the regexp ".*" will match only characters that are part
-of the file name. Also "^.*$" can be used to match at the beginning
-of the file name and at the end of the file name. This is used only
-when searching on file names. In Wdired this can be used when the new
-user option 'wdired-search-replace-filenames' is non-nil (which is the
-default).
-
-** Bookmarks
-
----
-*** 'list-bookmarks' now includes a type column.
-Types are registered via a 'bookmark-handler-type' symbol property on
-the jumping function.
-
-+++
-*** 'bookmark-sort-flag' can now be set to 'last-modified'.
-This will display bookmark list from most recently set to least
-recently set.
-
----
-*** When editing a bookmark annotation, 'C-c C-k' will now cancel.
-It is bound to the new command 'bookmark-edit-annotation-cancel'.
-
----
-*** New user option 'bookmark-fringe-mark'.
-This option controls the bitmap used to indicate bookmarks in the
-fringe (or nil to disable showing this marker).
-
-** Exif
-
----
-*** New function 'exif-field'.
-This is a convenience function to extract the field data from
-'exif-parse-file' and 'exif-parse-buffer'.
-
-** Xwidgets
-
----
-*** New user option 'xwidget-webkit-buffer-name-format'.
-This option controls how xwidget-webkit buffers are named.
-
----
-*** New user option 'xwidget-webkit-cookie-file'.
-This option controls whether the xwidget-webkit buffers save cookies
-set by web pages, and if so, in which file to save them.
-
-+++
-*** New minor mode 'xwidget-webkit-edit-mode'.
-When this mode is enabled, self-inserting characters and other common
-web browser shortcut keys are redefined to send themselves to the
-WebKit widget.
-
-+++
-*** New minor mode 'xwidget-webkit-isearch-mode'.
-This mode acts similarly to incremental search, and allows searching
-the contents of a WebKit widget. In xwidget-webkit mode, it is bound
-to 'C-s' and 'C-r'.
-
-+++
-*** New command 'xwidget-webkit-browse-history'.
-This command displays a buffer containing the page load history of
-the current WebKit widget, and allows you to navigate it.
-
----
-*** On X, the WebKit inspector is now available inside xwidgets.
-To access the inspector, right click on the widget and select "Inspect
-Element".
-
----
-*** "Open in New Window" in a WebKit widget's context menu now works.
-The newly created buffer will be displayed via 'display-buffer', which
-can be customized through the usual mechanism of 'display-buffer-alist'
-and friends.
-
-** Tramp
-
-+++
-*** New connection methods "docker", "podman" and "kubernetes".
-They allow accessing environments provided by Docker and similar
-programs.
-
----
-*** Tramp supports abbreviating remote home directories now.
-When calling 'abbreviate-file-name' on a Tramp file name, the result
-will abbreviate the user's home directory, for example by abbreviating
-"/ssh:user@host:/home/user" to "/ssh:user@host:~".
-
-+++
-*** New user option 'tramp-use-scp-direct-remote-copying'.
-When set to non-nil, Tramp does not copy files between two remote
-hosts via a local copy in its temporary directory, but lets the 'scp'
-command do this job.
-
-+++
-*** Proper password prompts for methods "doas", "sudo" and "sudoedit".
-The password prompts for these methods reflect now the credentials of
-the user requesting such a connection, and not of the user who is the
-target. This has always been needed, just the password prompt and the
-related 'auth-sources' entry were wrong.
-
-+++
-*** New user option 'tramp-completion-use-cache'.
-During user and host name completion in the minibuffer, results from
-Tramp's connection cache are taken into account. This can be disabled
-by setting the user option 'tramp-completion-use-cache' to nil.
-
-** Browse URL
-
----
-*** New user option 'browse-url-default-scheme'.
-This user option decides which URL scheme that 'browse-url' and
-related functions will use by default. For example, you could
-customize this to "https" to always prefer HTTPS URLs.
-
----
-*** New user option 'browse-url-irc-function'.
-This option specifies a function for opening "irc://" links. It
-defaults to the new function 'browse-url-irc'.
-
----
-*** New function 'browse-url-irc'.
-This multipurpose autoloaded function can be used for opening "irc://"
-and "ircs://" URLS by any caller that passes a URL string as an initial
-arg.
-
----
-*** Support for the Netscape web browser has been removed.
-This support has been obsolete since Emacs 25.1. The final version of
-the Netscape web browser was released in February, 2008.
-
----
-*** Support for the Galeon web browser has been removed.
-This support has been obsolete since Emacs 25.1. The final version of
-the Galeon web browser was released in September, 2008.
-
----
-*** Support for the Mozilla web browser is now obsolete.
-Note that this historical web browser is different from Mozilla
-Firefox; it is its predecessor.
-
-** Python Mode
-
-+++
-*** Project shells and a new user option 'python-shell-dedicated'.
-When called with a prefix argument, 'run-python' now offers the choice
-of creating a shell dedicated to the current project. This shell runs
-in the project root directory and is shared among all project buffers.
-
-Without a prefix argument, the kind of shell (buffer-dedicated,
-project-dedicated or global) is specified by the new
-'python-shell-dedicated' user option.
-
-** Ruby Mode
-
----
-*** New user option 'ruby-toggle-block-space-before-parameters'.
-
-** Eshell
-
-+++
-*** New feature to easily bypass Eshell's own pipelining.
-Prefixing '|', '<' or '>' with an asterisk, i.e. '*|', '*<' or '*>',
-will cause the whole command to be passed to the operating system
-shell. This is particularly useful to bypass Eshell's own pipelining
-support for pipelines which will move a lot of data. See section
-"Running Shell Pipelines Natively" in the Eshell manual, node
-"(eshell) Input/Output".
-
-+++
-*** New module to help supplying absolute file names to remote commands.
-After enabling the new 'eshell-elecslash' module, typing a forward
-slash as the first character of a command line argument will
-automatically insert the Tramp prefix. The automatic insertion
-applies only when 'default-directory' is remote and the command is a
-Lisp function. This frees you from having to keep track of whether
-commands are Lisp function or external when supplying absolute file
-name arguments. See the "(eshell) Electric forward slash" node in the
-Eshell manual for details.
-
-+++
-*** Improved support for redirection operators in Eshell.
-Eshell now supports a wider variety of redirection operators. For
-example, you can now redirect both stdout and stderr via '&>' or
-duplicate one output handle to another via 'NEW-FD>&OLD-FD'. For more
-information, see the "(eshell) Redirection" node in the Eshell manual.
-
-+++
-*** New eshell built-in command 'doas'.
-The privilege-escalation program 'doas' has been added to the existing
-'su' and 'sudo' commands from the 'eshell-tramp' module. The external
-command may still be accessed by using '*doas'.
-
-+++
-*** Double-quoting an Eshell expansion now treats the result as a single
string.
-If an Eshell expansion like '$FOO' is surrounded by double quotes, the
-result will always be a single string, no matter the type that would
-otherwise be returned.
-
-+++
-*** Concatenating Eshell expansions now works more similarly to other shells.
-When concatenating an Eshell expansion that returns a list, "adjacent"
-elements of each operand are now concatenated together,
-e.g. '$(list "a" "b")c' returns '("a" "bc")'. See the "(eshell)
-Expansion" node in the Eshell manual for more details.
-
-+++
-*** Eshell subcommands with multiline numeric output return lists of numbers.
-If every line of the output of an Eshell subcommand like '${COMMAND}'
-is numeric, the result will be a list of numbers (or a single number
-if only one line of output). Previously, this only converted numbers
-when there was a single line of output.
-
----
-*** Built-in Eshell commands now follow POSIX/GNU argument syntax conventions.
-Built-in commands in Eshell now accept command-line options with
-values passed as a single token, such as '-oVALUE' or
-'--option=VALUE'. New commands can take advantage of this with the
-'eshell-eval-using-options' macro. See "Defining new built-in
-commands" in the "(eshell) Built-ins" node of the Eshell manual.
-
----
-*** Eshell globs ending with '/' now match only directories.
-Additionally, globs ending with '**/' or '***/' no longer raise an
-error, and now expand to all directories recursively (following
-symlinks in the latter case).
-
-+++
-*** Lisp forms in Eshell now treat a nil result as a failed exit status.
-When executing a command that looks like '(lisp form)' and returns
-nil, Eshell will set the exit status (available in the '$?'
-variable) to 2. This allows commands like that to be used in
-conditionals. To change this behavior, customize the new
-'eshell-lisp-form-nil-is-failure' user option.
-
-** Shell
-
----
-*** New user option 'shell-kill-buffer-on-exit'.
-Enabling this will automatically kill a "*shell*" buffer as soon as
-the shell session terminates.
-
----
-*** New minor mode 'shell-highlight-undef-mode'.
-Customize 'shell-highlight-undef-enable' to t if you want to enable
-this minor mode in "*shell*" buffers. It will highlight undefined
-commands with a warning face as you type.
-
-** Calc
-
-+++
-*** New user option 'calc-kill-line-numbering'.
-Set it to nil to exclude line numbering from kills and copies.
-
-** Hierarchy
-
-+++
-*** Tree Display can delay computation of children.
-'hierarchy-add-tree' and 'hierarchy-add-trees' have an optional
-argument which allows tree-widget display to be activated and computed
-only when the user expands the node.
-
-** Miscellaneous
-
----
-*** New user option 'webjump-use-internal-browser'.
-When non-nil, WebJump will use an internal browser to open web pages,
-instead of the default external browser.
-
-+++
-*** New user option 'font-lock-ignore'.
-This option provides a mechanism to selectively disable font-lock
-keyword-driven fontifications.
-
----
-*** New user option 'auto-save-visited-predicate'.
-This user option is a predicate function which is called by
-'auto-save-visited-mode' to decide whether or not to save a buffer.
-You can use it to automatically save only specific buffers, for
-example buffers using a particular mode or in some directory.
-
----
-*** New user option 'remote-file-name-inhibit-auto-save-visited'.
-If this user option is non-nil, 'auto-save-visited-mode' will not
-auto-save remote buffers. The default is nil.
-
-+++
-*** New package vtable.el for formatting tabular data.
-This package allows formatting data using variable-pitch fonts.
-The resulting tables can display text in variable pitch fonts, text
-using fonts of different sizes, and images. See the "(vtable) Top"
-manual for more details.
-
----
-*** New minor mode 'elide-head-mode'.
-Enabling this minor mode turns on hiding header material, like
-'elide-head' does; disabling it shows the header. The commands
-'elide-head' and 'elide-head-show' are now obsolete.
-
-*** New package ansi-osc.el.
-Support for OSC ("Operating System Command") escape sequences has been
-extracted from comint.el in order to provide interpretation of OSC
-sequences in compilation buffers.
-
-Adding the new function 'ansi-osc-compilation-filter' to
-'compilation-filter-hook' enables interpretation of OSC escape
-sequences in compilation buffers. By default, all sequences are
-filtered out.
-
-The list of handlers (already covering OSC 7 and 8) has been extended
-with a handler for OSC 2, the command to set a window title.
-
-+++
-*** New user option 'project-vc-include-untracked'.
-If non-nil, files untracked by a VCS are considered to be part of
-the project by a VC project based on that VCS.
-
----
-*** 'recentf-mode' now uses abbreviated file names by default.
-This means that e.g. "/home/foo/bar" is now displayed as "~/bar".
-Customize the user option 'recentf-filename-handlers' to nil to get
-back the old behavior.
-
----
-*** New command 'recentf-open'.
-This command prompts for a recently opened file in the minibuffer, and
-visits it.
-
----
-*** 'ffap-machine-at-point' no longer pings hosts by default.
-It will now simply look at a hostname to determine if it is valid,
-instead of also trying to ping it. Customize the user option
-'ffap-machine-p-known' to 'ping' to get the old behavior back.
-
----
-*** The 'run-dig' command is now obsolete; use 'dig' instead.
-
----
-*** Some 'bib-mode' commands and variables have been renamed.
-To respect Emacs naming conventions, the variable 'unread-bib-file'
-has been renamed to 'bib-unread-file'. The following commands have
-also been renamed:
- 'addbib' to 'bib-add'
- 'return-key-bib' to 'bib-return-key'
- 'mark-bib' to 'bib-mark'
- 'unread-bib' to 'bib-unread'
-
----
-*** proced.el shows system processes of remote hosts.
-When 'default-directory' is remote, and 'proced' is invoked with a
-negative argument like 'C-u - proced', the system processes of that
-remote host are shown. Alternatively, the user option
-'proced-show-remote-processes' can be set to non-nil.
-'proced-signal-function' has been marked obsolete.
-
----
-*** 'outlineify-sticky' command is renamed to 'allout-outlinify-sticky'.
-The old name is still available as an obsolete function alias.
-
----
-*** The url-irc library now understands "ircs://" links.
-
----
-*** New command 'world-clock-copy-time-as-kill' for 'M-x world-clock'.
-It copies the current line into the kill ring.
-
----
-*** 'edit-abbrevs' now uses font-locking.
-The new face 'abbrev-table-name' is used to display the abbrev table
-name.
-
----
-*** New key binding 'O' in 'M-x list-buffer'.
-This key is now bound to 'Buffer-menu-view-other-window', which will
-view this line's buffer in View mode in another window.
-
-
-* New Modes and Packages in Emacs 29.1
-
-+++
-** Eglot: Emacs Client for the Language Server Protocol.
-Emacs now comes with the Eglot package, which enhances various Emacs
-features, such as completion, documentation, error detection, etc.,
-based on data provided by language servers using the Language Server
-Protocol (LSP).
-
-+++
-** New commands 'image-crop' and 'image-cut.
-These commands allow interactively cropping/cutting the image at
-point. The commands are bound to keys 'i c' and 'i x' (respectively)
-in the local keymap over images. They rely on external programs, by
-default "convert" from ImageMagick, to do the actual cropping/eliding
-of the image file.
-
----
-** New package 'wallpaper'.
-This package provides the command 'wallpaper-set', which sets the
-desktop background image. Depending on the system and the desktop,
-this may require an external program (such as "swaybg", "gm",
-"display" or "xloadimage"). If so, a suitable command should be
-detected automatically in most cases. It can also be customized
-manually if needed, using the new user options 'wallpaper-command' and
-'wallpaper-command-args'.
-
-+++
-** New package 'oclosure'.
-Allows the creation of "functions with slots" or "function objects"
-via the macros 'oclosure-define' and 'oclosure-lambda'.
-
-+++
-*** New generic function 'oclosure-interactive-form'.
-Used by 'interactive-form' when called on an OClosure.
-This allows specific OClosure types to compute their interactive specs
-on demand rather than precompute them when created.
-
----
-** New theme 'leuven-dark'.
-This is a dark version of the 'leuven' theme.
-
-+++
-** New mode 'erts-mode'.
-This mode is used to edit files geared towards testing actions in
-Emacs buffers, like indentation and the like. The new ert function
-'ert-test-erts-file' is used to parse these files.
-
----
-** New mode 'js-json-mode'.
-This is a lightweight variant of 'js-mode' that is used by default
-when visiting JSON files.
-
-** New mode 'typescript-ts-mode'.
-A major mode based on the tree-sitter library for editing programs
-in the TypeScript language. It includes support for font-locking,
-indentation, and navigation.
-
-** New mode 'c-ts-mode'.
-A major mode based on the tree-sitter library for editing programs
-in the C language. It includes support for font-locking,
-indentation, Imenu, which-func, and navigation.
-
-** New mode 'c++-ts-mode'.
-A major mode based on the tree-sitter library for editing programs
-in the C++ language. It includes support for font-locking,
-indentation, Imenu, which-func, and navigation.
-
-** New mode 'java-ts-mode'.
-A major mode based on the tree-sitter library for editing programs
-in the Java language. It includes support for font-locking,
-indentation, Imenu, which-func, and navigation.
-
-** New mode 'css-ts-mode'.
-A major mode based on the tree-sitter library for editing programs
-in the CSS language. It includes support for font-locking,
-indentation, Imenu, which-func, and navigation.
-
-** New mode 'json-ts-mode'.
-A major mode based on the tree-sitter library for editing programs
-in the JSON language. It includes support for font-locking,
-indentation, Imenu, which-func, and navigation.
-
-** New mode 'csharp-ts-mode'.
-A major mode based on the tree-sitter library for editing programs
-in the C# language. It includes support for font-locking,
-indentation, Imenu, which-func, and navigation.
-
-** New mode 'csharp-mode'.
-A major mode based on CC Mode for editing programs in the C# language.
-
-
-* Incompatible Lisp Changes in Emacs 29.1
-
-+++
-** 'format-prompt' now uses 'substitute-command-keys'.
-This means that both the prompt and 'minibuffer-default-prompt-format'
-will have key definitions and single quotes handled specially.
-
----
-** 'find-image' now uses 'create-image'.
-This means that images found through 'find-image' also have
-auto-scaling applied. (This only makes a difference on HiDPI
-displays.)
-
-+++
-** Changes to "raw" in-memory xbm images are specified.
-Some years back Emacs gained the ability to scale images, and you
-could then specify ':width' and ':height' when using 'create-image' on all
-image types -- except xbm images, because this format already used the
-':width' and ':height' arguments to specify the width/height of the "raw"
-in-memory format. This meant that if you used these specifications
-on, for instance, xbm files, Emacs would refuse to display them. This
-has been changed, and ':width'/':height' now works as with all other image
-formats, and the way to specify the width/height of the "raw"
-in-memory format is now by using ':data-width' and ':data-height'.
-
-+++
-** "loaddefs.el" generation has been reimplemented.
-The various "loaddefs.el" files in the Emacs tree (which contain
-information about autoloads, built-in packages and package prefixes)
-used to be generated by functions in autoloads.el. These are now
-generated by loaddefs-gen.el instead. This leads to functionally
-equivalent "loaddef.el" files, but they do not use exactly the same
-syntax, so using 'M-x update-file-autoloads' no longer works. (This
-didn't work well in most files in the past, either, but it will now
-signal an error in any file.)
-
-In addition, files are scanned in a slightly different way.
-Previously, ';;;###' specs inside a top-level form (i.e., something
-like '(when ... ;;;### ...)' would be ignored. They are now parsed as
-normal.
-
----
-** Themes have special autoload cookies.
-All built-in themes are scraped for ';;;###theme-autoload' cookies
-that are loaded along with the regular auto-loaded code.
-
-+++
-** 'buffer-modified-p' has been extended.
-This function was previously documented to return only nil or t. This
-has been changed to nil/'autosaved'/non-nil. The new 'autosaved'
-value means that the buffer is modified, but that it hasn't been
-modified since the time of last auto-save.
-
----
-** 'with-silent-modifications' also restores buffer autosave status.
-'with-silent-modifications' is a macro meant to be used by the font
-locking machinery to allow applying text properties without changing
-the modification status of the buffer. However, it didn't restore the
-buffer autosave status, so applying font locking to a modified buffer
-that had already been auto-saved would trigger another auto-saving.
-This is no longer the case.
-
----
-** 'prin1' doesn't always escape "." and "?" in symbols any more.
-Previously, symbols like 'foo.bar' would be printed by 'prin1' as
-"foo\.bar". This now prints as "foo.bar" instead. The Emacs Lisp
-reader interprets these strings as referring to the same symbol, so
-this is virtually always backwards-compatible, but there may
-theoretically be code out there that expects a specific printed
-representation.
-
-The same is the case with the "?" character: The 'foo?' symbol is now
-printed as "foo?" instead of "foo\?".
-
-If the "." and "?" characters are the first character in the symbol,
-they will still be escaped, so the '.foo' symbol is still printed as
-"\.foo" and the '?bar' symbol is still printed as "\?bar".
-
-+++
-** Remapping 'mode-line' no longer works as expected.
-'mode-line' is now the parent face of the new 'mode-line-active' face,
-and remapping parent of basic faces does not work reliably.
-Instead of remapping 'mode-line', you have to remap 'mode-line-active'.
-
-+++
-** 'make-process' has been extended to support ptys when ':stderr' is set.
-Previously, setting ':stderr' to a non-nil value would force the
-process's connection to use pipes. Now, Emacs will use a pty for
-stdin and stdout if requested no matter the value of ':stderr'.
-
----
-** User option 'mail-source-ignore-errors' is now obsolete.
-The whole mechanism for prompting users to continue in case of
-mail-source errors has been removed, so this option is no longer
-needed.
-
-** Fonts
-
----
-*** Emacs now supports 'medium' fonts.
-Emacs previously didn't distinguish between the 'regular'/'normal'
-weight and the 'medium' weight, but it now also supports the (heavier)
-'medium' weight. However, this means that if you previously specified
-a weight of 'normal' and the font doesn't have this weight, Emacs
-won't find the font spec. In these cases, replacing ":weight 'normal"
-with ":weight 'medium" should fix the issue.
-
----
-** Keymap descriptions have changed.
-'help--describe-command', 'C-h b' and associated functions that output
-keymap descriptions have changed. In particular, prefix commands are
-not output at all, and instead of "??" for closures/functions,
-"[closure]"/"[lambda]" is output.
-
----
-** 'downcase' details have changed slightly.
-In certain locales, changing the case of an ASCII-range character may
-turn it into a multibyte character, most notably with "I" in Turkish
-(the lowercase is "ı", 0x0131). Previously, 'downcase' on a unibyte
-string was buggy, and would mistakenly just return the lower byte of
-this, 0x31 (the digit "1"). 'downcase' on a unibyte string has now
-been changed to downcase such characters as if they were ASCII. To
-get proper locale-dependent downcasing, the string has to be converted
-to multibyte first. (This goes for the other case-changing functions,
-too.)
-
----
-** Functions in 'tramp-foreign-file-name-handler-alist' have changed.
-Functions to determine which Tramp file name handler to use are now
-passed a file name in dissected form (via 'tramp-dissect-file-name')
-instead of in string form.
-
----
-** 'def' indentation changes.
-In 'emacs-lisp-mode', forms with a symbol with a name that start with
-"def" have been automatically indented as if they were 'defun'-like
-forms, for instance:
-
- (defzot 1
- 2 3)
-
-This heuristic has now been removed, and all functions/macros that
-want to be indented this way have to be marked with
-
- (declare (indent defun))
-
-or the like. If the function/macro definition itself can't be
-changed, the indentation can also be adjusted by saying something
-like:
-
- (put 'defzot 'lisp-indent-function 'defun)
-
----
-** The 'inhibit-changing-match-data' variable is now obsolete.
-Instead, functions like 'string-match' and 'looking-at' now take an
-optional INHIBIT-MODIFY argument.
-
----
-** 'gnus-define-keys' is now obsolete.
-Use 'define-keymap' instead.
-
----
-** MozRepl has been removed from js.el.
-MozRepl was removed from Firefox in 2017, so this code doesn't work
-with recent versions of Firefox.
-
----
-** The function 'image-dired-get-exif-data' is now obsolete.
-Use 'exif-parse-file' and 'exif-field' instead.
-
----
-** 'insert-directory' alternatives should not change the free disk space line.
-This change is now applied in 'dired-insert-directory'.
-
----
-** 'compilation-last-buffer' is (finally) declared obsolete.
-It's been obsolete since Emacs-22.1, actually.
-
----
-** Calling 'lsh' now elicits a byte-compiler warning.
-'lsh' behaves in somewhat surprising and platform-dependent ways for
-negative arguments, and is generally slower than 'ash', which should be
-used instead. This warning can be suppressed by surrounding calls to
-'lsh' with the construct '(with-suppressed-warnings ((suspicious lsh)) ...)',
-but switching to 'ash' is generally much preferable.
-
----
-** Some functions and variables obsolete since Emacs 24 have been removed:

-** Some functions and variables obsolete since Emacs 23 have been removed:
-'find-emacs-lisp-shadows', 'newsticker-cache-filename',
-'process-filter-multibyte-p', 'redisplay-end-trigger-functions',
-'set-process-filter-multibyte', 'set-window-redisplay-end-trigger',
-'unify-8859-on-decoding-mode', 'unify-8859-on-encoding-mode',
-'vc-arch-command', 'window-redisplay-end-trigger', 'x-selection'.
-
----
-** Some functions and variables obsolete since Emacs 21 or 22 have been
removed:
-'c-toggle-auto-state', 'find-file-not-found-hooks',
-'ls-lisp-dired-ignore-case', 'query-replace-regexp-eval'.
-
-+++
-** New generic function 'function-documentation'.
-Can dynamically generate a raw docstring depending on the type of
-a function.
-Used mainly for docstrings of OClosures.
-
-+++
-** Base64 encoding no longer tolerates latin-1 input.
-The functions 'base64-encode-string', 'base64url-encode-string',
-'base64-encode-region' and 'base64url-encode-region' no longer accept
-characters in the range U+0080..U+00FF as substitutes for single bytes
-in the range 128..255, but signal an error for all multibyte characters.
-The input must be encoded text.
-
-+++
-** The 'clone-indirect-buffer-hook' is now run by 'make-indirect-buffer'.
-It was previously only run by 'clone-indirect-buffer' and
-'clone-indirect-buffer-other-window'. Since 'make-indirect-buffer' is
-called by both of these, the hook is now run by all 3 of these
-functions.
-
----
-** '?\' at the end of a line now signals an error.
-Previously, it produced a nonsense value, -1, that was never intended.
-
----
-** Some libraries obsolete since Emacs 24.1 and 24.3 have been removed:
-abbrevlist.el, assoc.el, complete.el, cust-print.el,
-erc-hecomplete.el, mailpost.el, mouse-sel.el, old-emacs-lock.el,
-patcomp.el, pc-mode.el, pc-select.el, s-region.el, and sregex.el.
-
-+++
-** Many seldom-used generalized variables have been made obsolete.
-Emacs has a number of rather obscure generalized variables defined,
-that, for instance, allowed you to say things like:
-
- (setf (point-min) 4)
-
-These never caught on and have been made obsolete. The form above,
-for instance, is the same as saying
-
- (narrow-to-region 4 (point-max))
-
-The following generalized variables have been made obsolete:
-'buffer-file-name', 'buffer-local-value', 'buffer-modified-p',
-'buffer-name', 'buffer-string', 'buffer-substring', 'current-buffer',
-'current-column', 'current-global-map', 'current-input-mode',
-'current-local-map', 'current-window-configuration',
-'default-file-modes', 'documentation-property', 'eq', 'frame-height',
-'frame-width', 'frame-visible-p', 'global-key-binding',
-'local-key-binding', 'mark', 'mark-marker', 'marker-position',
-'mouse-position', 'point', 'point-marker', 'point-max', 'point-min',
-'read-mouse-position', 'screen-height', 'screen-width',
-'selected-frame', 'selected-screen', 'selected-window',
-'standard-case-table', 'syntax-table', 'visited-file-modtime',
-'window-height', 'window-width', and 'x-get-secondary-selection'.
-
-
-* Lisp Changes in Emacs 29.1
-
-+++
-** Interpreted closures are "safe for space".
-As was already the case for byte-compiled closures, instead of capturing
-the whole current lexical environment, interpreted closures now only
-capture the part of the environment that they need.
-The previous behavior could occasionally lead to memory leaks or
-to problems where a printed closure would not be 'read'able because
-of an un'read'able value in an unrelated lexical variable.
-
-+++
-** New accessor function 'file-attribute-file-identifier'.
-It returns the list of the inode number and device identifier
-retrieved by 'file-attributes'. This value can be used to identify a
-file uniquely. The device identifier can be a single number or (for
-remote files) a cons of 2 numbers.
-
-+++
-** New macro 'while-let'.
-This is like 'when-let', but repeats until a binding form is nil.
-
-+++
-** New function 'make-obsolete-generalized-variable'.
-This can be used to mark setters used by 'setf' as obsolete, and the
-byte-compiler will then warn about using them.
-
-+++
-** New functions 'pos-eol' and 'pos-bol'.
-These are like 'line-end-position' and 'line-beginning-position'
-(respectively), but ignore fields (and are more efficient).
-
-+++
-** New function 'compiled-function-p'.
-This returns non-nil if its argument is either a built-in, or a
-byte-compiled, or a natively-compiled function object, or a function
-loaded from a dynamic module.
-
----
-** 'deactivate-mark' can have new value 'dont-save'.
-This value means that Emacs should deactivate the mark as usual, but
-without setting the primary selection, if 'select-active-regions' is
-enabled.
-
-+++
-** New 'declare' form 'interactive-args'.
-This can be used to specify what forms to put into 'command-history'
-when executing commands interactively.
-
-+++
-** The FORM arg of 'time-convert' is mandatory.
-'time-convert' can still be called without it, as before, but the
-compiler now emits a warning about this deprecated usage.
-
-+++
-** Emacs now supports user-customizable and themable icons.
-These can be used for buttons in buffers and the like. See the
-"(elisp) Icons" and "(emacs) Icons" nodes in the manuals for details.
-
-+++
-** New arguments MESSAGE and TIMEOUT of 'set-transient-map'.
-MESSAGE specifies a message to display after activating the transient
-map, including a special formatting spec to list available keys.
-TIMEOUT is the idle time after which to deactivate the transient map.
-The default timeout value can be defined by the new variable
-'set-transient-map-timeout'.
-
-** Connection-local variables
-
-+++
-*** Some connection-local variables are now user options.
-The variables 'connection-local-profile-alist' and
-'connection-local-criteria-alist' are now user options, in order to
-make it more convenient to inspect and modify them.
-
-+++
-*** New function 'connection-local-update-profile-variables'.
-This function allows to modify the settings of an existing
-connection-local profile.
-
-+++
-*** New macro 'with-connection-local-application-variables'.
-This macro works like 'with-connection-local-variables', but it allows
-to use another application but 'tramp'. This is useful when running
-code in a buffer where Tramp has already set some connection-local
-variables.
-
-+++
-*** New macro 'setq-connection-local'.
-This allows dynamically setting variable values for a particular
-connection within the body of 'with-connection-local-{application-}variables'.
-See the "(elisp) Connection Local Variables" node in the Lisp
-Reference manual for more information.
-
-+++
-** 'plist-get', 'plist-put' and 'plist-member' are no longer limited to 'eq'.
-These function now take an optional comparison predicate argument.
-
-+++
-** 'read-multiple-choice' can now use long-form answers.
-
-+++
-** 'M-c' in 'read-regexp' now toggles case folding.
-
-+++
-** 'completing-read' now allows a function as its REQUIRE-MATCH argument.
-This function is called to see whether what the user has typed in is a
-match. This is also available from functions that call
-'completing-read', like 'read-file-name'.
-
-+++
-** 'posn-col-row' can now give position data based on windows.
-Previously, it reported data only based on the frame.
-
-+++
-** 'file-expand-wildcards' can now also take a regexp as PATTERN argument.
-
----
-** vc-mtn (the backend for Monotone) has been made obsolete.
-
-+++
-** 'gui-set-selection' can now specify different values for different data
types.
-If DATA is a string, then its text properties are searched for values
-for each specific data type while the selection is being converted.
-
----
-** New eldoc function 'elisp-eldoc-var-docstring-with-value'.
-This function includes the current value of the variable in eldoc display
-and can be used as a more detailed alternative to 'elisp-eldoc-var-docstring'.
-
-+++
-** 'save-some-buffers' can now be extended to save other things.
-Traditionally, 'save-some-buffers' saved buffers, and also saved
-abbrevs. This has been generalized via the
-'save-some-buffers-functions' variable, and packages can now register
-things to be saved.
-
-+++
-** New function 'string-equal-ignore-case'.
-This compares strings ignoring case differences.
-
-** 'symbol-file' can now report natively-compiled ".eln" files.
-If Emacs was built with native-compilation enabled, Lisp programs can
-now call 'symbol-file' with the new optional 3rd argument non-nil to
-request the name of the ".eln" file which defined a given symbol.
-
-+++
-** New macro 'with-memoization' provides a very primitive form of memoization.
-
-+++
-** 'max-char' can now report the maximum codepoint according to Unicode.
-When called with a new optional argument UNICODE non-nil, 'max-char'
-will now report the maximum valid codepoint defined by the Unicode
-Standard.
-
-** seq
-
-+++
-** New function 'seq-split'.
-This returns a list of sub-sequences of the specified sequence.
-
-+++
-** New function 'seq-remove-at-position'.
-This function returns a copy of the specified sequence where the
-element at a given (zero-based) index got removed.
-
-+++
-** New function 'seq-positions'.
-This returns a list of the (zero-based) indices of elements matching a
-given predicate in the specified sequence.
-
-+++
-** New function 'seq-keep'.
-This is like 'seq-map', but removes all nil results from the returned
-list.
-
-** Themes
-
----
-*** New hooks 'enable-theme-functions' and 'disable-theme-functions'.
-These are run after enabling and disabling a theme, respectively.
-
----
-*** Themes can now be made obsolete.
-Using 'make-obsolete' on a theme is now supported. This will make
-'load-theme' issue a warning when loading the theme.
-
-+++
-** New hook 'display-monitors-changed-functions'.
-It is called whenever the configuration of different monitors on a
-display changes.
-
-+++
-** 'prin1' and 'prin1-to-string' now take an optional OVERRIDES parameter.
-This parameter can be used to override values of print-related settings.
-
-+++
-** New minor mode 'header-line-indent-mode'.
-This is meant to be used in modes that have a header line that should
-be kept aligned with the buffer contents when the user switches
-'display-line-numbers-mode' on or off.
-
-+++
-** New minor mode 'lost-selection-mode'.
-This minor mode makes Emacs deactivate the mark in all buffers when
-the primary selection is obtained by another program.
-
----
-** On X, Emacs will try to preserve selection ownership when a frame is
deleted.
-This means that if you make Emacs the owner of a selection, such as by
-selecting some text into the clipboard or primary selection, and then
-delete the current frame, you will still be able to insert the
-contents of that selection into other programs as long as another
-frame is open on the same display. This behavior can be disabled by
-setting the user option 'x-auto-preserve-selections' to nil.
-
-+++
-** New predicate 'char-uppercase-p'.
-This returns non-nil if its argument its an uppercase character.
-
-** Byte compilation
-
----
-*** Byte compilation will now warn about some quoting mistakes in docstrings.
-When writing code snippets that contains the "'" character (APOSTROPHE),
-that quote character has to be escaped to avoid Emacs displaying it as
-"’" (LEFT SINGLE QUOTATION MARK), which would make code examples like
-
- (setq foo '(1 2 3))
-
-invalid. Emacs will now warn during byte compilation if it seems
-something like that, and also warn about when using RIGHT/LEFT SINGLE
-QUOTATION MARK directly. In both these cases, if these characters
-should really be present in the docstring, they should be quoted with
-"\=".
-
----
-*** Byte compilation will now warn about some malformed 'defcustom' types.
-It's very common to write 'defcustom' types on the form:
-
- :type '(choice (const :tag "foo" 'bar))
-
-I.e., double-quoting the 'bar', which is almost never the correct
-value. The byte compiler will now issue a warning if it encounters
-these forms.
-
-+++
-** 'restore-buffer-modified-p' can now alter buffer auto-save state.
-With a FLAG value of 'autosaved', it will mark the buffer as having
-been auto-saved since the time of last modification.
-
----
-** New minor mode 'isearch-fold-quotes-mode'.
-This sets up 'search-default-mode' so that quote characters are
-char-folded into each other. It is used, by default, in "*Help*" and
-"*info*" buffers.
-
-+++
-** New macro 'buffer-local-set-state'.
-This is a helper macro to be used by minor modes that wish to restore
-buffer-local variables back to their original states when the mode is
-switched off.
-
----
-** New macro 'with-buffer-unmodified-if-unchanged'.
-If the buffer is marked as unmodified, and code does modifications
-that, in total, means that the buffer is identical to the buffer
-before, mark the buffer as unmodified again.
-
----
-** New function 'malloc-trim'.
-This function allows returning unused memory back to the operating
-system, and is mainly meant as a debugging tool. It is currently
-available only when Emacs was built with glibc as the C library.
-
----
-** 'x-show-tip' no longer hard-codes a timeout default.
-The new 'x-show-tooltip-timeout' variable allows the user to alter
-this for packages that don't use 'tooltip-show', but instead call the
-lower level function directly.
-
----
-** New function 'current-cpu-time'.
-It gives access to the CPU time used by the Emacs process, for
-example for benchmarking purposes.
-
----
-** New function 'string-edit'.
-This is meant to be used when the user has to edit a (potentially)
-long string. It pops you to a new buffer where you can edit the
-string, and a callback is called when the user types 'C-c C-c'.
-
-+++
-** New function 'read-string-from-buffer'.
-This is a modal version of 'string-edit', and can be used as an
-alternative to 'read-string'.
-
-+++
-** The return value of 'clear-message-function' is not ignored anymore.
-If the function returns 'dont-clear-message', then the message is not
-cleared, with the assumption that the function cleared it itself.
-
-+++
-** The local variable section now supports defining fallback modes.
-This was previously only available when using a property line (i.e.,
-putting the modes on the first line of a file).
-
-+++
-** New function 'flush-standard-output'.
-This enables you to display incomplete lines from batch-based Emacs
-scripts.
-
-+++
-** New convenience function 'buttonize-region'.
-This works like 'buttonize', but for a region instead of a string.
-
-+++
-** 'macroexp-let2*' can omit TEST arg and use single-var bindings.
-
-+++
-** New macro-writing macros, 'cl-with-gensyms' and 'cl-once-only'.
-See the "(cl) Macro-Writing Macros" manual section for descriptions.
-
-+++
-** New variable 'last-event-device' and new function 'device-class'.
-On X Windows, 'last-event-device' specifies the input extension device
-from which the last input event originated, and 'device-class' can be
-used to determine the type of an input device.
-
-+++
-** 'track-mouse' can be a new value 'drag-source'.
-This means the same as 'dropping', but modifies the mouse position
-list in reported motion events if there is no frame underneath the
-mouse pointer.
-
-+++
-** New functions for dragging items from Emacs to other programs.
-The new functions 'x-begin-drag', 'dnd-begin-file-drag',
-'dnd-begin-drag-files', and 'dnd-direct-save' allow dragging contents
-(such as files and text) from Emacs to other programs.
-
----
-** New function 'ietf-drums-parse-date-string'.
-This function parses RFC5322 (and RFC822) date strings, and should be
-used instead of 'parse-time-string' when parsing data that's standards
-compliant.
-
-+++
-** New macro 'setopt'.
-This is like 'setq', but is meant to be used for user options instead
-of plain variables, and
-uses 'custom-set'/'set-default' to set them.
-
-+++
-** New utility predicate 'mode-line-window-selected-p'.
-This is meant to be used from ':eval' mode line constructs to create
-different mode line looks for selected and unselected windows.
-
-+++
-** New variable 'messages-buffer-name'.
-This variable (defaulting to "*Messages*") allows packages to override
-where messages are logged.
-
-+++
-** New function 'readablep'.
-This function says whether an object can be written out and then
-read back by the Emacs Lisp reader.
-
-+++
-** New variable 'print-unreadable-function'.
-This variable allows changing how Emacs prints unreadable objects.
-
----
-** The user option 'polling-period' now accepts floating point values.
-This means Emacs can now poll for input during Lisp execution more
-frequently than once in a second.
-
----
-** New function 'bidi-string-strip-control-characters'.
-This utility function is meant for displaying strings when it's
-essential that there's no bidirectional context.
-
----
-** The Gnus range functions have been moved to a new library, range.el.
-All the old names have been made obsolete.
-
-+++
-** New function 'function-alias-p'.
-This predicate says whether an object is a function alias, and if it
-is, the alias chain is returned.
-
-+++
-** New variable 'lisp-directory' holds the directory of Emacs's own Lisp files.
-
-+++
-** New facility for handling session state: 'multisession-value'.
-This can be used as a convenient way to store (simple) application
-state, and the command 'list-multisession-values' allows users to list
-(and edit) this data.
-
-+++
-** New function 'get-display-property'.
-This is like 'get-text-property', but works on the 'display' text
-property.
-
-+++
-** New function 'add-display-text-property'.
-This is like 'put-text-property', but works on the 'display' text
-property.
-
-+++
-** New 'min-width' 'display' property.
-This allows setting a minimum display width for a region of text.
-
-+++
-** New 'cursor-face' text property.
-This uses 'cursor-face' instead of the default face when cursor is on or
-near the character and 'cursor-face-highlight-mode' is enabled. The
-user option 'cursor-face-highlight-nonselected-window' is similar to
-'highlight-nonselected-windows', but for this property.
-
-+++
-** New event type 'touch-end'.
-This event is sent whenever the user's finger moves off the mouse
-wheel on some mice, or when the user's finger moves off the touchpad.
-
-+++
-** New event type 'pinch'.
-This event is sent when a user performs a pinch gesture on a touchpad,
-which is comprised of placing two fingers on the touchpad and moving
-them towards or away from each other.
-
-+++
-** New hook 'x-pre-popup-menu-hook'.
-This hook is run before 'x-popup-menu' is about to display a
-deck-of-cards menu on screen.
-
----
-** New hook 'post-select-region-hook'.
-This hook is run immediately after 'select-active-regions' causes the
-region to be set as the primary selection.
-
-+++
-** New function 'buffer-match-p'.
-Check if a buffer satisfies some condition. Some examples for
-conditions can be regular expressions that match a buffer name, a
-cons-cell like '(major-mode . shell-mode)' that matches any buffer
-where 'major-mode' is 'shell-mode' or a combined with a condition like
-'(and "\\`\\*.+\\*\\'" (major-mode . special-mode))'.
-
-+++
-** New function 'match-buffers'.
-Use 'buffer-match-p' to gather a list of buffers that match a
-condition.
-
----
-** New optional arguments 'text-face' and 'default-face' for 'tooltip-show'.
-They allow changing the faces used for the tooltip text and frame
-colors of the resulting tooltip frame from the default 'tooltip' face.
-
-** Text security and suspiciousness
-
-+++
-*** New library textsec.el.
-This library contains a number of checks for whether a string is
-"suspicious". This usually means that the string contains characters
-that have glyphs that can be confused with other, more commonly used
-glyphs, or contain bidirectional (or other) formatting characters that
-may be used to confuse a user.
-
-+++
-*** New user option 'textsec-check'.
-If non-nil (which is the default), Emacs packages that are vulnerable
-to attackers trying to confuse the users will use the textsec library
-to mark suspicious text. For instance shr/eww will mark suspicious
-URLs and links, Gnus will mark suspicious From addresses, and
-Message mode will query the user if the user is sending mail to a
-suspicious address. If this variable is nil, these checks aren't
-performed.
-
-+++
-*** New function 'textsec-suspicious-p'.
-This is the main function Emacs applications should be using to check
-whether a string is suspicious. It heeds the 'textsec-check' user
-option.
-
-** Keymaps and key definitions
-
-+++
-*** 'where-is-internal' can now filter events marked as non key events.
-If a command maps to a key binding like '[some-event]', and 'some-event'
-has a symbol plist containing a non-nil 'non-key-event' property, then
-that binding is ignored by 'where-is-internal'.
-
-+++
-*** New functions for defining and manipulating keystrokes.
-These all take the syntax defined by 'key-valid-p'. None of the older
-functions have been deprecated or altered, but they are now
-de-emphasized in the documentation.
-
-+++
-*** Use 'keymap-set' instead of 'define-key'.
-
-+++
-*** Use 'keymap-global-set' instead of 'global-set-key'.
-
-+++
-*** Use 'keymap-local-set' instead of 'local-set-key'.
-
-+++
-*** Use 'keymap-global-unset' instead of 'global-unset-key'.
-
-+++
-*** Use 'keymap-local-unset' instead of 'local-unset-key'.
-
-+++
-*** Use 'keymap-substitute' instead of 'substitute-key-definition'.
-
-+++
-*** Use 'keymap-set-after' instead of 'define-key-after'.
-
-+++
-*** Use 'keymap-lookup' instead of 'lookup-keymap' and 'key-binding'.
-
-+++
-*** Use 'keymap-local-lookup' instead of 'local-key-binding'.
-
-+++
-*** Use 'keymap-global-lookup' instead of 'global-key-binding'.
-
-+++
-*** 'define-key' now takes an optional REMOVE argument.
-If non-nil, remove the definition from the keymap. This is subtly
-different from setting a definition to nil (when the keymap has a
-parent).
-
-+++
-*** 'read-multiple-choice' now takes an optional SHOW-HELP argument.
-If non-nil, show the help buffer immediately, before any user input.
-
-+++
-*** New function 'key-valid-p'.
-The 'kbd' function is quite permissive, and will try to return
-something usable even if the syntax of the argument isn't completely
-correct. The 'key-valid-p' predicate does a stricter check of the
-syntax.
-
----
-*** New function 'key-parse'.
-This is like 'kbd', but only returns vectors instead of a mix of
-vectors and strings.
-
-+++
-*** New ':type' for 'defcustom' for keys.
-The new 'key' type can be used for options that should be a valid key
-according to 'key-valid-p'. The type 'key-sequence' is now obsolete.
-
-+++
-** New substitution in docstrings and 'substitute-command-keys'.
-Use \\`KEYSEQ' to insert a literal key sequence "KEYSEQ" (for example
-\\`C-k') in a docstring or when calling 'substitute-command-keys',
-which will use the same face as a command substitution. This should
-be used only when a key sequence has no corresponding command, for
-example when it is read directly with 'read-key-sequence'. It must be
-a valid key sequence according to 'key-valid-p'.
-
-+++
-** New function 'file-name-split'.
-This returns a list of all the components of a file name.
-
-+++
-** New function 'file-name-parent-directory'.
-This returns the parent directory of a file name.
-
-+++
-** New macro 'with-undo-amalgamate'.
-It records a particular sequence of operations as a single undo step.
-
-+++
-** New command 'yank-media'.
-This command supports yanking non-plain-text media like images and
-HTML from other applications into Emacs. It is only supported in
-modes that have registered support for it, and only on capable
-platforms.
-
-+++
-** New command 'yank-media-types'.
-This command lets you examine all data in the current selection and
-the clipboard, and insert it into the buffer.
-
-+++
-** New variable 'yank-transform-functions'.
-This variable allows the user to alter the string to be inserted.
-
----
-** New command 'yank-in-context'.
-This command tries to preserve string/comment syntax when yanking.
-
----
-** New function 'minibuffer-lazy-highlight-setup'.
-This function allows setting up the minibuffer so that lazy
-highlighting of its content is applied in the original window.
-
-+++
-** New text property 'inhibit-isearch'.
-If set, 'isearch' will skip these areas, which can be useful (for
-instance) when covering huge amounts of data (that has no meaningful
-searchable data, like image data) with a 'display' text property.
-
-+++
-** 'insert-image' now takes an INHIBIT-ISEARCH optional parameter.
-It marks the image with the 'inhibit-isearch' text property, which
-inhibits 'isearch' matching the STRING parameter.
-
----
-** New variable 'replace-regexp-function'.
-Function to call to convert the entered FROM string to an Emacs
-regexp in 'query-replace' and similar commands. It can be used to
-implement a different regexp syntax for search/replace.
-
----
-** New variables to customize defaults of FROM for 'query-replace*' commands.
-The new variable 'query-replace-read-from-default' can be set to a
-function that returns the default value of FROM when 'query-replace'
-prompts for a string to be replaced. An example of such a function is
-'find-tag-default'.
-
-The new variable 'query-replace-read-from-regexp-default' can be set
-to a function (such as 'find-tag-default-as-regexp') that returns the
-default value of FROM when 'query-replace-regexp' prompts for a regexp
-whose matches are to be replaced. If these variables are nil (which
-is the default), 'query-replace' and 'query-replace-regexp' take the
-default value from the previous FROM-TO pair.
-
----
-** New user option 'pp-use-max-width'.
-If non-nil, 'pp' will attempt to limit the line length when formatting
-long lists and vectors.
-
----
-** New function 'pp-emacs-lisp-code'.
-'pp' formats general Lisp sexps. This function does much the same,
-but applies formatting rules appropriate for Emacs Lisp code.
-
-+++
-** New function 'file-has-changed-p'.
-This convenience function is useful when writing code that parses
-files at run-time, and allows Lisp programs to re-parse files only
-when they have changed.
-
-+++
-** 'abbreviate-file-name' now respects magic file name handlers.
-
----
-** New function 'font-has-char-p'.
-This can be used to check whether a specific font has a glyph for a
-character.
-
-+++
-** 'window-text-pixel-size' now accepts a new argument IGNORE-LINE-AT-END.
-This controls whether or not the last screen line of the text being
-measured will be counted for the purpose of calculating the text
-dimensions.
-
-+++
-** 'window-text-pixel-size' understands a new meaning of FROM.
-Specifying a cons as the FROM argument allows to start measuring text
-from a specified amount of pixels above or below a position.
-
-+++
-** 'window-body-width' and 'window-body-height' can use remapped faces.
-Specifying 'remap' as the PIXELWISE argument now checks if the default
-face was remapped, and if so, uses the remapped face to determine the
-character width/height.
-
-+++
-** 'set-window-vscroll' now accepts a new argument PRESERVE-VSCROLL-P.
-This means the vscroll will not be reset when set on a window that is
-"frozen" due to a mini-window being resized.
-
-** XDG support
-
----
-*** New function 'xdg-state-home'.
-It returns the new 'XDG_STATE_HOME' environment variable. It should
-point to a file name that "contains state data that should persist
-between (application) restarts, but that is not important or portable
-enough to the user that it should be stored in $XDG_DATA_HOME".
-(This variable was introduced in the XDG Base Directory Specification
-version 0.8 released on May 8, 2021.)
-
----
-*** New function 'xdg-current-desktop'.
-It returns a list of strings, corresponding to the colon-separated
-list of names in the 'XDG_CURRENT_DESKTOP' environment variable, which
-identify the current desktop environment.
-(This variable was introduced in XDG Desktop Entry Specification
-version 1.2.)
-
----
-*** New function 'xdg-session-type'.
-It returns the 'XDG_SESSION_TYPE' environment variable. (This is not
-part of any official standard; see the man page pam_systemd(8) for
-more information.)
-
-+++
-** New macro 'with-delayed-message'.
-This macro is like 'progn', but will output the specified message if
-the body takes longer to execute than the specified timeout.
-
----
-** New function 'funcall-with-delayed-message'.
-This function is like 'funcall', but will output the specified message
-if the function takes longer to execute than the specified timeout.
-
-** Locale
-
----
-*** New variable 'current-locale-environment'.
-This holds the value of the previous call to 'set-locale-environment'.
-
----
-*** New macro 'with-locale-environment'.
-This macro can be used to change the locale temporarily while
-executing code.
-
-** table.el
-
----
-*** New user option 'table-latex-environment'.
-This allows switching between "table" and "tabular".
-
-** Tabulated List Mode
-
-+++
-*** A column can now be set to an image descriptor.
-The 'tabulated-list-entries' variable now supports using an image
-descriptor, which means to insert an image in that column instead of
-text. See the documentation string of that variable for details.
-
-+++
-** ':keys' in 'menu-item' can now be a function.
-If so, it is called whenever the menu is computed, and can be used to
-calculate the keys dynamically.
-
-+++
-** New major mode 'clean-mode'.
-This is a new major mode meant for debugging. It kills absolutely all
-local variables and removes overlays and text properties.
-
-+++
-** 'kill-all-local-variables' can now kill all local variables.
-If given the new optional KILL-PERMANENT argument, also kill permanent
-local variables.
-
-+++
-** Third 'mapconcat' argument SEPARATOR is now optional.
-An explicit nil always meant the empty string, now it can be left out.
-
-+++
-** New function 'define-keymap'.
-This function allows defining a number of keystrokes with one form.
-
-+++
-** New macro 'defvar-keymap'.
-This macro allows defining keymap variables more conveniently.
-
-** 'defvar-keymap' can specify 'repeat-mode' behavior for the keymap.
-Use ':repeat t' to have all bindings be repeatable or for more
-advanced usage:
-
- ':repeat (:enter (commands ...) :exit (commands ...))'
-
----
-** 'kbd' can now be used in built-in, preloaded libraries.
-It no longer depends on edmacro.el and cl-lib.el.
-
-+++
-** New function 'image-at-point-p'.
-This function returns t if point is on a valid image, and nil
-otherwise.
-
-+++
-** New function 'buffer-text-pixel-size'.
-This is similar to 'window-text-pixel-size', but can be used when the
-buffer isn't displayed.
-
-+++
-** New function 'string-pixel-width'.
-This returns the width of a string in pixels. This can be useful when
-dealing with variable pitch fonts and glyphs that have widths that
-aren't integer multiples of the default font.
-
-+++
-** New function 'string-glyph-split'.
-This function splits a string into a list of strings representing
-separate glyphs. This takes into account combining characters and
-grapheme clusters.
-
----
-** 'lookup-key' is more permissive when searching for extended menu items.
-In Emacs 28.1, the behavior of 'lookup-key' was changed: when looking
-for a menu item '[menu-bar Foo-Bar]', first try to find an exact
-match, then look for the lowercased '[menu-bar foo-bar]'.
-
-This has been extended, so that when looking for a menu item with a
-symbol containing spaces, as in '[menu-bar Foo\ Bar]', first look for
-an exact match, then the lowercased '[menu-bar foo\ bar]' and finally
-'[menu-bar foo-bar]'. This further improves backwards-compatibility
-when converting menus to use 'easy-menu-define'.
-
-** xwidgets
-
-+++
-*** The function 'make-xwidget' now accepts an optional RELATED argument.
-This argument is used as another widget for the newly created WebKit
-widget to share settings and subprocesses with. It must be another
-WebKit widget.
-
-+++
-*** New function 'xwidget-perform-lispy-event'.
-This function allows you to send events to xwidgets. Usually, some
-equivalent of the event will be sent, but there is no guarantee of
-what the widget will actually receive.
-
-On GTK+, only key and function key events are implemented.
-
-+++
-*** New function 'xwidget-webkit-load-html'.
-This function is used to load HTML text into WebKit xwidgets
-directly, in contrast to creating a temporary file to hold the
-markup, and passing the URI of the file as an argument to
-'xwidget-webkit-goto-uri'.
-
-+++
-*** New functions for performing searches on WebKit xwidgets.
-Some new functions, such as 'xwidget-webkit-search', have been added
-for performing searches on WebKit xwidgets.
-
-+++
-*** New function 'xwidget-webkit-back-forward-list'.
-This function returns the history of page-loads in a WebKit xwidget.
-
-+++
-*** New function 'xwidget-webkit-estimated-load-progress'.
-This function returns the estimated progress of page loading in a
-WebKit xwidget.
-
-+++
-*** New function 'xwidget-webkit-stop-loading'.
-This function terminates all data transfer during page loads in a
-WebKit xwidget.
-
-+++
-*** 'load-changed' xwidget events are now more detailed.
-In particular, they can now have different arguments based on the
-state of the WebKit widget. 'load-finished' is sent when a load has
-completed, 'load-started' when a load first starts, 'load-redirected'
-after a redirect, and 'load-committed' when the WebKit widget first
-commits to the load.
-
-+++
-*** New event type 'xwidget-display-event'.
-These events are sent whenever an xwidget requests that Emacs display
-another xwidget. The only arguments to this event are the xwidget
-that should be displayed, and the xwidget that asked to display it.
-
-+++
-*** New function 'xwidget-webkit-set-cookie-storage-file'.
-This function is used to control where and if an xwidget stores
-cookies set by web pages on disk.
-
----
-** New variable 'help-buffer-under-preparation'.
-This variable is bound to t during the preparation of a "*Help*" buffer.
-
-+++
-** Timestamps like '(1 . 1000)' now work without warnings being generated.
-For example, '(time-add nil '(1 . 1000))' no longer warns that the
-'(1 . 1000)' acts like '(1000 . 1000000)'. This warning, which was a
-temporary transition aid for Emacs 27, has served its purpose.
-
-+++
-** 'encode-time' now also accepts a 6-element list with just time and date.
-'(encode-time (list SECOND MINUTE HOUR DAY MONTH YEAR))' is now short for
-'(encode-time (list SECOND MINUTE HOUR DAY MONTH YEAR nil -1 nil))'.
-
-+++
-** 'date-to-time' now assumes earliest values if its argument lacks
-month, day, or time. For example, (date-to-time "2021-12-04") now
-assumes a time of 00:00 instead of signaling an error.
-
-+++
-** 'format-seconds' now allows suppressing zero-value trailing elements.
-The new "%x" non-printing control character will suppress zero-value
-elements that appear after "%x".
-
-+++
-** New events for taking advantage of touchscreen devices.
-The events 'touchscreen-begin, 'touchscreen-update', and
-'touchscreen-end' have been added to take better advantage of
-touch-capable display panels.
-
-+++
-** New error symbol 'permission-denied'.
-This is a subcategory of 'file-error', and is signaled when some file
-operation fails because the OS doesn't allow Emacs to access a file or
-a directory.
-
-+++
-** The ':underline' face attribute now accepts a new property.
-The property ':position' now specifies the position of the underline
-when used as part of a property list specification for the
-':underline' attribute.
-
-+++
-** 'defalias' records a more precise history of definitions.
-This is recorded in the 'function-history' symbol property.
-
----
-** New hook 'save-place-after-find-file-hook'.
-This is called at the end of 'save-place-find-file-hook'.
-
----
-** 'indian-tml-base-table' no longer translates digits.
-Use 'indian-tml-base-digits-table' if you want digits translation.
-
----
-** 'indian-tml-itrans-v5-hash' no longer translates digits.
-Use 'indian-tml-itrans-digits-v5-hash' if you want digits
-translation.
-
-+++
-** 'shell-quote-argument' has a new optional parameter POSIX.
-This is useful when quoting shell arguments for a remote shell
-invocation. Such shells are POSIX conformant by default.
-
-+++
-** 'make-process' can set connection type independently for input and output.
-When calling 'make-process', communication via pty can be enabled
-selectively for just input or output by passing a cons cell for
-':connection-type', e.g. '(pipe . pty)'. When examining a process
-later, you can determine whether a particular stream for a process
-uses a pty by passing one of 'stdin', 'stdout', or 'stderr' as the
-second argument to 'process-tty-name'.
-
-+++
-** 'signal-process' now consults the list 'signal-process-functions'.
-This is to determine which function has to be called in order to
-deliver the signal. This allows Tramp to send the signal to remote
-asynchronous processes. The hitherto existing implementation has been
-moved to 'internal-default-signal-process'.
-
-+++
-** Some system information functions honor remote systems now.
-'list-system-processes' returns remote process IDs.
-'memory-info' returns memory information of remote systems.
-'process-attributes' expects a remote process ID.
-This happens only when the current buffer's 'default-directory' is
-remote. In order to preserve the old behavior, bind
-'default-directory' to a local directory, like
-
- (let ((default-directory temporary-file-directory))
- (list-system-processes))
-
-+++
-** New functions 'take' and 'ntake'.
-'(take N LIST)' returns the first N elements of LIST; 'ntake' does
-the same but works by modifying LIST destructively.
-
----
-** 'string-split' is now an alias for 'split-string'.
-
-+++
-** 'format-spec' now accepts functions in the replacement.
-The function is called only when used in the format string. This is
-useful to avoid side-effects such as prompting, when the value is not
-actually being used for anything.
-
-+++
-** The variable 'max-specpdl-size' has been made obsolete.
-Now 'max-lisp-eval-depth' alone is used for limiting Lisp recursion
-and stack usage. 'max-specpdl-size' is still present as a plain
-variable for compatibility but its limiting powers have been taken away.
+
+* Lisp Changes in Emacs 30.1
-* Changes in Emacs 29.1 on Non-Free Operating Systems
-
-** MS-Windows
-
----
-*** Emacs now supports double-buffering on MS-Windows to reduce display
flicker.
-(This was supported on Free systems since Emacs 26.1.)
-
-To disable double-buffering (e.g., if it causes display problems), set
-the frame parameter 'inhibit-double-buffering' to a non-nil value.
-You can do that either by adding
-
- '(inhibit-double-buffering . t)
-
-to 'default-frame-alist', or by modifying the frame parameters of the
-selected frame by evaluating
-
- (modify-frame-parameters nil '((inhibit-double-buffering . t)))
-
-+++
-*** Emacs now supports system dark mode.
-On Windows 10 (version 1809 and higher) and Windows 11, Emacs will now
-follow the system's dark mode: GUI frames use the appropriate light or
-dark title bar and scroll bars, based on the user's Windows-wide color
-settings.
-
----
-*** Emacs now uses native image APIs to display some image formats.
-On Windows 2000 and later, Emacs now defaults to using the native
-image APIs for displaying the BMP, GIF, JPEG, PNG, and TIFF images.
-This means Emacs on MS-Windows needs no longer use external image
-support libraries to display those images. Other image types -- XPM,
-SVG, and WEBP -- still need support libraries for Emacs to be able to
-display them.
-
-The use of native image APIs is controlled by the variable
-'w32-use-native-image-API', whose value now defaults to t on systems
-where those APIs are available.
-
-+++
-*** Emacs now supports display of BMP images using native image APIs.
-When 'w32-use-native-image-API' is non-nil, Emacs on MS-Windows now
-has built-in support for displaying BMP images.
-
-** Cygwin
-
----
-*** 'process-attributes' is now implemented.
