* Changes in Emacs 21.4
+** line-move-ignore-invisible now defaults to t.
+
+** In Outline mode, hide-body no longer hides lines at the top
+of the file that precede the first header line.
+
++++
+** `set-auto-mode' now gives the interpreter magic line (if present)
+precedence over the file name. Likewise an <?xml or <!DOCTYPE declaration
+will give the buffer XML or SGML mode, based on the new var
+`magic-mode-alist'.
+
++++
+** New function `looking-back' checks whether a regular expression matches
+the text before point. Specifying the LIMIT argument bounds how far
+back the match can start; this is a way to keep it from taking too long.
+
++++
+** New functions `make-progress-reporter', `progress-reporter-update',
+`progress-reporter-force-update' and `progress-reporter-done' provide
+a simple and efficient way of printing progress messages to the user.
+
++++
+** In Enriched mode, `set-left-margin' and `set-right-margin' are now
+by default bound to `C-c [' and `C-c ]' instead of the former `C-c C-l'
+and `C-c C-r'.
+
++++
+** In processing a local variables list, Emacs strips the prefix and
+suffix are from every line before processing all the lines.
+
++++
+** `apply-macro-to-region-lines' now operates on all lines that begin
+in the region, rather than on all complete lines in the region.
+
+** global-whitespace-mode is a new alias for whitespace-global-mode.
+
+++
** There are now two new regular expression operators, \_< and \_>,
for matching the beginning and end of a symbol. A symbol is a
rule applies to file buffers. For non-file buffers, the behavior may
be mode dependent.
+If you are sure that the file will only change by growing at the end,
+then you can tail the file more efficiently by using the new minor
+mode Auto Revert Tail mode. The function `auto-revert-tail-mode'
+toggles this mode.
+
** Auto Revert mode is now more careful to avoid excessive reverts and
other potential problems when deciding which non-file buffers to
revert. This matters especially if Global Auto Revert mode is enabled
The new file etc/compilation.txt gives examples of each type of message.
-** M-x grep has been adapted to new compile
+** Compilation mode enhancements:
+
++++
+*** New user option `compilation-environment'.
+This option allows you to specify environment variables for inferior
+compilation processes without affecting the environment that all
+subprocesses inherit.
+
+** Grep has been decoupled from compilation mode setup.
+
+*** There's a new separate package grep.el.
+
+*** M-x grep has been adapted to new compile
Hits are fontified in green, and hits in binary files in orange. Grep buffers
can be saved and automatically revisited with the new Grep mode.
+*** Grep commands now have their own submenu and customization group.
+
+*** The new variables `grep-window-height', `grep-auto-highlight', and
+`grep-scroll-output' can be used to override the corresponding
+compilation mode settings for grep commands.
+
+*** New option `grep-highlight-matches' highlightes matches in *grep*
+buffer. It uses a special feature of some grep programs which accept
+--color option to output markers around matches. When going to the next
+match with `next-error' the exact match is highlighted in the source
+buffer. Otherwise, if `grep-highlight-matches' is nil, the whole
+source line is highlighted.
+
+*** New key bindings in grep output window:
+SPC and DEL scrolls window up and down. C-n and C-p moves to next and
+previous match in the grep window. RET jumps to the source line of
+the current match. `n' and `p' shows next and previous match in
+other window, but does not switch buffer. `{' and `}' jumps to the
+previous or next file in the grep output. TAB also jumps to the next
+file.
+
+** New options `next-error-highlight' and `next-error-highlight-no-select'
+specify the method of highlighting of the corresponding source line
+in new face `next-error'.
+
+** A new minor mode `next-error-follow-minor-mode' can be used in
+compilation-mode, grep-mode, occur-mode, and diff-mode (i.e. all the
+modes that can use `next-error'). In this mode, cursor motion in the
+buffer causes automatic display in another window of the corresponding
+matches, compilation errors, etc. This minor mode can be toggled with
+C-c C-f.
+
** M-x diff uses diff-mode instead of compilation-mode.
** M-x compare-windows now can automatically skip non-matching text to
the stroke directly to a string to insert. This is convenient for
using strokes as an input method.
+** Gnus package
+
+*** Gnus now includes Sieve and PGG
+Sieve is a library for managing Sieve scripts. PGG is a library to handle
+PGP/MIME.
+
+*** There are many news features, bug fixes and improvements.
+See the file GNUS-NEWS or the node "Oort Gnus" in the Gnus manual for details.

** On window systems, lines which are exactly as wide as the window

two lines on the display (with just the newline on the second line).
The new user option 'overflow-newline-into-fringe' may be set to nil to
revert to the old behaviour of continuing such lines.

** The buffer boundaries (i.e. first and last line in the buffer) may
now be marked with angle bitmaps in the fringes. In addition, up and

-For example, (t . right) places the top angle bitmap in left fringe,

+constraints can be marked as "scrolling commands". See the Emacs manual
+for details.
+
+++
** C-w in incremental search now grabs either a character or a word,
making the decision in a heuristic way. This new job is done by the
command `isearch-yank-word-or-char'. To restore the old behavior,
bind C-w to `isearch-yank-word' in `isearch-mode-map'.

** C-M-w deletes and C-M-y grabs a character in isearch mode.
Another method to grab a character is to enter the minibuffer by `M-e'

+** There is a new calendar package, icalendar.el, that can be used to
+convert Emacs diary entries to/from the iCalendar format.

** Diary sexp entries can have custom marking in the calendar.
Diary sexp functions which only apply to certain days (such as
year and day number, and moves to that date. Negative day numbers

+day of that ISO week.
+
+---
+** The functions `holiday-easter-etc' and `holiday-advent' now take
+arguments, and only report on the specified holiday rather than all.
+This makes customization of the variable `christian-holidays' simpler,
+but existing customizations may need to be updated.
+
** The function `simple-diary-display' now by default sets a header line.
This can be controlled through the variables `diary-header-line-flag'
and `diary-header-line-format'.
**** The `::' qualifier triggers C++ parsing in C file.
Previously, only the `template' and `class' keywords had this effect.
