Please send Emacs bug reports to bug-gnu-emacs@gnu.org.
** Support for GNU/Linux on IA64 machines has been added.
+** Support for LynxOS has been added.
+
** `movemail' defaults to supporting POP. You can turn this off using
the --without-pop configure option, should that be necessary.
regular expression. The mode is then determined as the mode
associated with that interpreter in `interpreter-mode-alist'.
++++
** C-down-mouse-3 is bound differently. Now if the menu bar is not
displayed it pops up a menu containing the items which would be on the
menu bar. If the menu bar is displayed, it pops up the major mode
using that menu.
** New function executable-make-buffer-file-executable-if-script-p is
-suitable as an after-save-hook as an alternative to executable-chmod.
+suitable as an after-save-hook as an alternative to `executable-chmod'.
** The most preferred coding-system is now used to save a buffer if
buffer-file-coding-system is `undecided' and it is safe for the buffer
** Variable `default-korean-keyboard' is initialized properly from the
environment variable `HANGUL_KEYBOARD_TYPE'.
++++
** C-u C-x = provides detailed information about the character at
point in a pop-up window.
** M-; now calls comment-dwim which tries to do something clever based
on the context.
++++
** The function `getenv' is now callable interactively.
** The many obsolete language `setup-...-environment' commands have
been removed -- use `set-language-environment'.
++++
** New user options `display-time-mail-face' and
`display-time-use-mail-icon' control the appearance of mode-line mail
indicator used by the display-time package. On a suitable display the
indicator can be an icon and is mouse-sensitive.
++++
** Emacs' auto-save list files are now by default stored in a
sub-directory `.emacs.d/auto-save-list/' of the user's home directory.
(On MS-DOS, this subdirectory's name is `_emacs.d/auto-save.list/'.)
You can customize `auto-save-list-prefix' to change this location.
++++
** On window-systems, additional space can be put between text lines
on the display using several methods
++++
- By setting frame parameter `line-spacing' to PIXELS. PIXELS must be
a positive integer, and specifies that PIXELS number of pixels should
be put below text lines on the affected frame or frames.
++++
- By setting X resource `lineSpacing', class `LineSpacing'. This is
equivalent ot specifying the frame parameter.
- By setting buffer-local variable `line-spacing'. The meaning is
the same, but applies to the a particular buffer only.
++++
** The new command `clone-indirect-buffer' can be used to create
an indirect buffer that is a twin copy of the current buffer. The
command `clone-indirect-buffer-other-window', bound to C-x 4 c,
does the same but displays the indirect buffer in another window.
++++
** New user options `backup-directory-alist' and
`make-backup-file-name-function' control the placement of backups,
typically in a single directory or in an invisible sub-directory.
compiler. Files compiled with XEmacs can contain byte codes that let
Emacs dump core.
++++
** New X resources recognized
*** The X resource `synchronous', class `Synchronous', specifies
shown, if non-nil a hollow box cursor is shown. This option can
be customized.
++++
** The variable `echo-keystrokes' may now have a floating point value.
++++
** C-x 5 1 runs the new command delete-other-frames which deletes
all frames except the selected one.
** New command M-x check-parens can be used to find unbalanced paren
groups and strings in buffers in Lisp mode (or other modes).
-** You can now easily create new *Info* buffers using either M-x clone-buffer
-or C-u m <entry> RET. M-x clone-buffer can also be used on *Help* and
-several other special buffers.
++++
+** You can now easily create new *Info* buffers using either
+M-x clone-buffer, C-u m <entry> RET or C-u g <entry> RET.
+M-x clone-buffer can also be used on *Help* and several other special
+buffers.

under XFree86. To enable this, simply put (mwheel-install) in your
.emacs file.
abbreviated file names. Abbreviations can be customized by changing
`directory-abbrev-alist'.
-** Reading from the mini-buffer now reads from standard input if Emacs
-is running in batch mode. For example,
-
- (message "%s" (read t))
-
-will read a Lisp expression from standard input and print the result
-to standard output.
-
** Faces and frame parameters.
There are four new faces `scroll-bar', `border', `cursor' and `mouse'.
Setting the font of LessTif/Motif menus is currently not supported;
attempts to set the font are ignored in this case.
++++
** New frame parameter `screen-gamma' for gamma correction.
The new frame parameter `screen-gamma' specifies gamma-correction for
** New default font is Courier 12pt.
-** When using a windowing terminal, Emacs window now has a cursor of
-its own. When the window is selected, the cursor is solid; otherwise,
-it is hollow.
++++
+** When using a windowing terminal, each Emacs window now has a cursor
+of its own. When the window is selected, the cursor is solid;
+otherwise, it is hollow.
** Bitmap areas to the left and right of windows are used to display
truncation marks, continuation marks, overlay arrows and alike. The

widgets for radio and toggle buttons in menus. When configured for
Lucid, Emacs draws radio buttons and toggle buttons similar to Motif.
++++
** Highlighting of trailing whitespace.
When `show-trailing-whitespace' is non-nil, Emacs displays trailing
Emacs can optionally display a busy-cursor under X. You can turn the
display on or off by customizing group `cursor'.
++++
** Blinking cursor
M-x blink-cursor-mode toggles a blinking cursor under X and on
** Enhancements of the Lucid menu bar
++++
*** The Lucid menu bar now supports the resource "margin".
emacs.pane.menubar.margin: 5
Emacs supports a tool bar at the top of a frame under X. For details
how to define a tool bar, see the page describing Lisp-level changes.
++++
** Mouse-sensitive mode line.
Different parts of the mode line under X have been made
- Mouse-3 on the buffer-name displays a buffer menu.
-- Mouse-2 on the read-only status in the mode line (`%' or `*')
-toggles the read-only status.
+- Mouse-2 on the read-only or modified status in the mode line (`%' or
+`*') toggles the status.
- Mouse-3 on the mode name display a minor-mode menu.
driver and native BSD driver, a.k.a. Luigi's driver). Currently
supported file formats are RIFF-WAVE (*.wav) and Sun Audio (*.au).
++++
** A new variable, backup-by-copying-when-privileged-mismatch, gives
the highest file uid for which backup-by-copying-when-mismatch will be
forced on. The assumption is that uids less than or equal to this
All these functions have been rewritten to avoid inserting unwanted
spaces, and an optional prefix now allows them to behave the old way.
++++
There is a new command M-x replace-rectangle.
** The new command M-x query-replace-regexp-eval acts like
** M-x query-replace recognizes a new command `e' (or `E') that lets
you edit the replacement string.
-** The new command mail-abbrev-complete-alias, bound to `M-TAB', let's
+** The new command mail-abbrev-complete-alias, bound to `M-TAB', lets
you complete mail aliases in the text, analogous to
lisp-complete-symbol.
** Changes to Change Log mode and Add-Log functions
++++
If you invoke `add-change-log-entry' from a backup file, it makes an
entry appropriate for the file's parent. This is useful for making
log entries by comparing a version with deleted functions.
++++
New command M-x change-log-merge merges another log into the current
-buffer, fixing old-style date formats if necessary.

+
++++
+New command M-x change-log-redate fixes any old-style date entries in
+a log file.
Change Log mode now adds a file's version number to change log entries
if user-option `change-log-version-info-enabled' is non-nil.
-The search for a file's version number is performed based on regular
-expressions from `change-log-version-number-regexp-list' which can be
-cutomized. Version numbers are only found in the first 10 percent of
-a file.
+Unless the file is under version control the search for a file's
+version number is performed based on regular expressions from
+`change-log-version-number-regexp-list' which can be cutomized.
+Version numbers are only found in the first 10 percent of a file.
** Changes in Font Lock
** Partial Completion mode now completes environment variables in
file names.
++++
** Tooltips.
Tooltips are small X windows displaying a help string at the current
the mouse in source buffers. You can customize various aspects of the
tooltip display in the group `tooltip'.
++++
** Customize changes
*** Customize now supports comments about customized items. Use the
** Changes to Ange-ftp
++++
*** Ange-ftp allows you to specify of a port number in remote file
names cleanly. It is appended to the host name, separated by a hash
sign, e.g. `/foo@bar.org#666:mumble'. (This syntax comes from EFS.)
*** Setting tags-apropos-verbose to a non-nil value displays the
names of tags files in the *Tags List* buffer.
++++
** Emacs now attempts to determine the initial language environment
and preferred and locale coding systems systematically from the
LC_ALL, LC_CTYPE, and LANG environment variables during startup.
8859-14 (Celtic) and 8859-15 (updated Latin-1, with the Euro sign).
There is currently no specific input method support for them.
++++
** Fortran mode has a new command `fortran-strip-sequence-nos' to
remove text past column 72. The syntax class of `\' in Fortran is now
appropriate for C-style escape sequences in strings.
** SGML mode's default `sgml-validate-command' is now `nsgmls'.
++++
** A new command `view-emacs-problems' (C-h P) displays the PROBLEMS file.

corresponding file is read.
++++
*** The new package zone.el plays games with Emacs' display when
Emacs is idle.
package which allows different styles of comment-region and should
be more robust while offering the same functionality.
++++
*** The Ebrowse package implements a C++ class browser and tags
facilities tailored for use with C++. It is documented in a
separate Texinfo file.
-*** The PCL-CVS package available by either running M-x cvs-examine
-or by visiting a CVS administrative directory (with a prefix argument)
-provides an alternative interface to VC-dired for CVS.
-It comes with log-view-mode to view RCS and SCCS logs and log-edit-mode

unreadableIdentifiersLikeThis readable. It works as glasses, without
actually modifying content of a buffer.
example, it will align variable names in declaration lists, or the
equal signs of assignments.
++++
*** `paragraph-indent-minor-mode' is a new minor mode supporting
paragraphs in the same style as `paragraph-indent-text-mode'.
++++
*** bs.el is a new package for buffer selection similar to
list-buffers or electric-buffer-list. Use M-x bs-show to display a
buffer menu with this package. You can use M-x bs-customize to
not be confused with "calc" which is a much bigger mathematical tool
which answers different needs.
++++
*** The minor modes cwarn-mode and global-cwarn-mode highlights
suspicious C and C++ constructions. Currently, assignments inside
expressions, semicolon following `if', `for' and `while' (except, of
reference parameters are recognized. The modes require font-lock mode
to be enabled.
++++
*** smerge-mode.el provides `smerge-mode', a simple minor-mode for files
containing diff3-style conflict markers, such as generated by RCS.

++++
*** The package recentf.el maintains a menu for visiting files that
were operated on recently.
*** elide-head.el provides a mechanism for eliding boilerplate header
text.
++++
*** footnote.el provides `footnote-mode', a minor mode supporting use
of footnotes. It is intended for use with Message mode, but isn't
specific to Message mode.
++++
*** diff-mode.el provides `diff-mode', a major mode for
viewing/editing context diffs (patches). It is selected for files
with extension `.diff', `.diffs', `.patch' and `.rej'.
++++
*** EUDC, the Emacs Unified Directory Client, provides a common user
interface to access directory servers using different directory
protocols. It has a separate manual.
*** autoconf.el provides a major mode for editing configure.in files
for Autoconf, selected automatically.

(Display-related features are described in a page of their own below.)
++++
+** Reading from the mini-buffer now reads from standard input if Emacs
+is running in batch mode. For example,
+

frame or window.
** The meaning of the `:weakness WEAK' argument of make-hash-table
has been changed.
++++
** Function `aset' stores any multibyte character in any string
without signaling "Attempt to change char length of a string". It may
convert a unibyte string to multibyte if necessary.
