[Carsten Dominik]

Hi,

I have released version 4.62 of org-mode.  Get it at

http://www.astro.uva.nl/~dominik/Tools/org/

This release contains incompatible changes to the table editor
spreadsheet.  If you are currently using the spreadsheet,
make sure to read the notes below carefully.

Enjoy

Changes in version 4.62
=======================

- Many changes to the spreadsheet functions in the table editor.
  This includes some incompatible changes.
  For deatils, please see the notes near the end of this message,
  and re-read section 3.4 in the manual.

    Triggered in part by requests from Eddward, Michael, Xiao-Yong.

- Selected text becomes the default description for C-c C-l links

    This excellent (and obviouos?) proposal comes from Scott Otterson

- The date format in the agenda/timeline views is now customizable.
  See the new option `org-agenda-date-format'.

    requested by Victor

- Link abbreviations no longer need a double colon, single colon is 
fine.

- The menu entry for org-archive advertizes the correct key, while the
  old key is still in place.

    thanks to Kai Grossjohann for pointing out how to do this.

- More bug fixes.


Details about the changes to the spreadsheet
============================================

   - It is now much easier to assign formulas to individual fields.
     In particular, the field does not have to be a named field
     anymore. Just type an equation preceeded by "=:" and it will be
     defined for the current field only.

   - A formula can reference any field or rectangular range in the
     table.  A field reference looks like @2$3 for the field in
     line 2 column 3 of the table.  Ranges look like @address@hidden
     and return vectors.

   - INCOMPATIBLE CHANGE:  The vector returned by a range no longer
     contains the empty fields in the range, so that vmean($2..$7)
     returns the true average of the numbers in the region, and not
     something smaller because empty fields are assumed to be 0.  You
     may use the "E" mode switch to get the old behavior, but the
     default has changed.

   - INCOMPATIBLE CHANGE: The "&..." format for referencing fields
     and ranges in the current column is no longer supported.  You
     need to modify formulas that use this to the new "@..." ranges.
     I decided to provide no backward compatibility for this, because
     the "&..." stuff was logically a mess.

   - Ranges can also be used in Lisp formulas.

   - INCOMPATIBLE CHANGE:  Insertion of fields into Lisp formulas has
     changed, values are inserted as strings by default.  If you use
     Lisp formulas to do computations, add the ;N mode flag to the
     formula, like $4 = '(+ $1 $2 $3);N

   - Field coordinates can also be defined relative to the current
     row/column, for example @+2$-1.

   - Rows can be specified relative to horizontal separator lines,
     for example @address@hidden are the fields between the second and
     third such lines in the table.

   - Absolut references are automatically modified if you use
     Org-mode commands to insert/delete/swap columns *and* rows.
     This is cool, new, and needs testing!  So check before you
     blindly believe, and report any bugs.

   - Org-mode shows referenced fields by highlighting them in
     different colors.  While editing a formula inside a table field
     you need to press `C-c ?' to get the reference at point
     highlighted.  From the formula editor (accessible with C-c ')
     this even happens automatically.
