+
** The delete key now deletes forward by default.
This is regulated by the variable `delete-key-deletes-forward', which
Delete key to delete backwards, despite the presence (according to
Xlib) of a BackSpace key on the keyboard.
+** Shifted motion keys now select text by default.
+
+You can turn this off by setting `shifted-motion-keys-select-region'
+to nil. This works based off of particular keys, not particular
+commands: Thus, the arrow keys will normally trigger selection when
+the Shift key is held down regardless of their bindings, and non-arrow
+keys with the same bindings (e.g. C-f) will not work this way. You
+can control which keys trigger shifted motion using
+`motion-keys-for-shifted-motion'. See also
+`unshifted-motion-keys-deselect-region'.
+
** You can now build XEmacs with support for GTK+ widget set.
XEmacs built that way uses GTK+ to draw menubars, scrollbars, and
system.) Gnome widgets and functionality are supported where
available, and can be turned off.
-** Shifted motion keys now select text by default.
+** ~/.xemacs/init.el is now the preferred location for the init file.
-You can turn this off by setting `shifted-motion-keys-select-region'
-to nil. This works based off of particular keys, not particular
-commands: Thus, the arrow keys will normally trigger selection when

-can control which keys trigger shifted motion using
-`motion-keys-for-shifted-motion'. See also
-`unshifted-motion-keys-deselect-region'.
+*** XEmacs now supports a `~/.xemacs/init.el' startup file.
+If it exists, XEmacs will prefer it over `.emacs' and `.emacs.el'.
+The file may be byte-compiled as `~/.xemacs/init.elc'.
+
+If present, the `~/.xemacs/' directory may contain startup files for
+XEmacs packages that support it.
+
+The first time you start up XEmacs, it will ask you if you would like
+to migrate your `.emacs' to the new location. (Your custom settings
+will also be moved, to `~/.xemacs/custom.el' -- see below.) If so, you
+will also be asked whether you would like to create a compatibility
+`.emacs' for backward compatibility with previous versions of XEmacs
+and with GNU Emacs. (This compatibility `.emacs' simply loads the new
+init and custom files.) Doing this is generally a good idea -- new
+versions of XEmacs will prefer `~/.xemacs/init.el' over `~/.emacs' in
+any case.
+
+You can manually migrate at any time with `migrate-user-init-file',
+and undo any migration with `unmigrate-user-init-file'. The function
+`create-compatibility-dot-emacs' also lets you manually create a
+compatibility `.emacs'.
+
+NOTE: Under MS Windows, your home directory (i.e. the directory named
+`~') is specified by the HOME environment variable, and defaults to
+C:\. To set this variable, modify AUTOEXEC.BAT under Windows 95/98,
+or select Control Panel->System->Advanced->Environment Variables...
+under Windows NT/2000.
+
+*** Custom file will move to ~/.xemacs/custom.el.
+
+Whereas customize settings were formerly stored in the regular init
+file, XEmacs now prefers them to be in a separate file
+`~/.xemacs/custom.el', completely under automatic control. This
+change goes with the migration of the init file, and XEmacs offers
+automatic migration upon startup.
+
+** Much-improved sample init.el, showing how to use many useful features.
+
+The sample init file, located in the `etc/' directory of the XEmacs
+installation, has been renamed from `sample.emacs' to `sample.init.el',
+and pretty much rewritten from scratch. (You can view it by selecting
+the menu item Help->Samples->Sample init.el.) Many of the most-useful
+optional features in XEmacs have been enabled, and other features that
+are useful but may be annoying to some are present but commented out.
+There is also extensive documentation on how to add your own
+improvements to the init file and where to find more documentation
+elsewhere in XEmacs. The file has been specifically designed so that
+most people can simply make it their own init file by copying it to
+~/.xemacs/init.el, and they will be satisfied with the results.
** XEmacs support for menu accelerators has been much improved.
** Default menubar improvements.
-*** The default menubar has been extensively reorganized. Many more

+*** The old clunky file dialog box is improved.
+The in-buffer file dialog box (visible on non-MS-Windows, non-GTK
systems) is still clunky but has had many improvements to make it work
significantly better.
*** Keyboard traversal now works correctly in MS Windows dialog boxes.
-*** There is a Search dialog box available from Edit->Find..., but it
-is very experimental and needs a lot of work.

+However, it's very experimental and needs a lot of work.
** New buffer tabs.
-You can now use the buffer tabs to switch between buffers.
+You can now use buffer tabs to switch between buffers.
The tabs are located between the toolbar and the uppermost window, in
-a location called "gutter". If you dislike the buffer tabs, you can
-disable them by customizing `gutter-buffers-tab-visible-p', or by
-placing this in your .emacs:
+a location called the "gutter". If you dislike the buffer tabs, you can
+disable them using the menu item `Options->Display->Buffers Tab Visible'
+by customizing `gutter-buffers-tab-visible-p', or by placing this in
+your .xemacs/init.el:
- (set-gutter-element-visible-p default-gutter-visible-p 'buffers-tab nil)
+ (custom-set-variables '(gutter-buffers-tab-visible-p nil))
-You can change the location of the gutter with
-`set-default-gutter-position', however currently only MS Windows
-supports tab widgets with orientations other than vertical.
+You can change the location of the gutter using the menu item
+`Options->Display->Default Gutter Location' or with (e.g.)
-There are menu items on the Options menu to conveniently change these
-settings.
+ (custom-set-variables '(default-gutter-position 'left))
+
+However, currently only MS Windows supports tab widgets with
+orientations other than vertical, and it doesn't currently support
+gutters on the bottom of the frame.
** There is a new MS Windows installer, netinstall, ported from Cygwin.
Nearly complete automation of the XEmacs install process from
ftp.xemacs.org. Includes selection of Lisp packages to install, etc.
-** The subprocess quote-handling mechanism under MS Windows is much improved.
+** The subprocess quote-handling mechanism under Windows is much improved.
Specifically, the quote-handling mechanism has been completely rewritten,
and you should now be able to use single or double quotes to quote arguments
** Selection improvements.
-*** Kill and yank now interact with the clipboard by default under
-Windows. This was done by changing the default value of
-`interprogram-cut-function' and `interprogram-paste-function'. You
-can get the old behavior by setting these to nil, and there is an
-option on the options menu to do this.

as this would break the MS Windows model. If you want this behavior
then set `selection-sets-clipboard' to t.
-*** Motif selection support is now more correct (but slower) in its
-behaviour. Changes have been made to allow correct operation of
-cut/copy/paste operations between native widgets and XEmacs buffers.
-However, this can lead to a lot of X traffic which slows down the
-performance of `C-k'. If you want the old behaviour then set

`x-selection-strict-motif-ownership' to nil.
** Mail spool locking now works correctly.
** International support changes.
-*** The "coding system" feature now works even in an XEmacs compiled
-without international (Mule) support. This means that for example
-XEmacs can recognize the newline convention used by the file you are
-editing.
-
-*** The default coding-priority-list is now safer. This means that if
-you have no language environment set, Mule no longer automatically
-recognizes ISO 2022 escapes in your files. This makes editing binary
-files safe.
-
-*** International keysyms are now supported under X. This means that
-XEmacs running under Mule will automatically recognize the keysym
-`scaron' to be the lower-case `s' with caron in the Latin 2 character
-set. (Specifically, it will bind the keysym to `self-insert' and
-augment its `ascii-character' property.) This is very useful with
-XFree under European locales as shipped by recent Linux distributions.
-If XEmacs is compiled without Mule support, the feature still works,
-but it is unaware of different character sets -- it unconditionally
-sets the `ascii-character' property to values in the [160, 256) range.
-
-*** MS Windows 1251 code page is now supported as coding system
-`windows-1251'.
-
-*** Czech, Thai, Cyrillic-KOI8, Vietnamese, Ethiopic support now
-available.
+*** The default coding-priority-list is now safer.

+makes editing binary files safe.
+
+*** International keysyms are now supported under X.
-*** The appropriate characters in Latin 3 and Latin 4 character sets
-are correctly defined as words.
+This means that XEmacs running under Mule will automatically recognize
+the keysym `scaron' to be the lower-case `s' with caron in the Latin 2

+
+*** Proper support for words in Latin 3 and Latin 4.
+
+The appropriate characters in Latin 3 and Latin 4 character sets are
+correctly defined as words.
** Help buffers contain hyperlinks, and other changes.
-*** The help buffers created by C-h commands now contain hyperlinks to
-other commands, functions and variables mentioned in the
-documentation. Use button2 to follow a link. Use button3 to bring up
-a context menu that lets you follow the link, find the source for the
-item, do a tag search, etc. The buffers are also syntax-highlighted.

+
+Help functions (e.g. `C-h f') now know how to print macro argument
+lists. If your macro definition included an argument list for the sake
+of help output, you no longer need to do that.

+** The modeline's text is now scrollable.
-** The modeline's text is now scrollable. This is controlled by the
-variable `modeline-scrolling-method', which you need to set to a
-non-nil value. You can also choose scrolling types; see the docstring

** Interactive searching and matching case improvements.

+*** Incremental search will now highlight all visible matches.
+
+This makes it easier to anticipate where consecutive C-s or C-r will
+place the point. If you want to disable the feature, set
`isearch-highlight-all-matches' to nil.
-*** Case sensitiveness in searching operations is normally controlled
+*** Interactive searches always respect uppercase characters.
+
+Case sensitiveness in searching operations is normally controlled
by the variable `case-fold-search' (if non-nil, case is ignored while
searching). This mechanism has now been slightly improved for
interactive searches: if the search string (or regexp) contains
searches, like `zap-to-char', `list-matching-lines', `tags-search'
etc. The incremental search facility has always behaved that way.
-** The rectangle functions have been almost completely rewritten in
+** Rectangle functions rewritten to avoid inserting extra spaces.
+
+The rectangle functions have been almost completely rewritten in
order to avoid inserting undesirable spaces, notably at the end of
lines. Two typical examples of the old behavior were
`string-rectangle', which filled all lines up to the right side of the
understands the special value `coerce', which means that the line
should not be filled if it is too short to reach the desired column.
-** There is a new command `kill-entire-line' that always kills the
-entire line at point, regardless of whether the point is at the
-beginning of line, and regardless of the setting of `kill-whole-line'.
+** New command `kill-entire-line' that always kills the entire line.
+
+This kills the entire line at point, regardless of whether the point
+is at the beginning of line, and regardless of the setting of
+`kill-whole-line'.
-** When you press RET at a minibuffer prompt that provides a default
+** Default values correctly stored in minibuffer histories.
+
+When you press RET at a minibuffer prompt that provides a default
value, the value is stored in history instead of an empty line. Also,
you can now edit the default value by pressing the down arrow,
accessing the logical "future" value. Not all minibuffer prompts have
yet been converted to support this feature.
-** You can now create "indirect buffers", like in GNU Emacs. An
-indirect buffer shares its text with another buffer ("base buffer"),
-but has its own major mode, local variables, extents, and narrowing.
-An indirect buffer has a name of its own, distinct from those of the
-base buffer and all other buffers. An indirect buffer cannot itself
-be visiting a file (though its base buffer can be). The base buffer
-cannot itself be indirect.

do not like this behavior, set `progress-feedback-use-echo-area' to
nil.
-** User names following the tilde character can now be completed at
-file name prompts; e.g. `C-x C-f ~hni<TAB>' will complete to
-`~hniksic/'. To make this operation faster, a cache of user names is
-maintained internally.

+e.g. `C-x C-f ~hni<TAB>' will complete to `~hniksic/'. To make this
+operation faster, a cache of user names is maintained internally.
The new primitives available for this purpose are functions named
`user-name-completion' and `user-name-all-completions'.
** Indentation no longer indents comments that begin at column zero.
This makes it easy to deal with commented out regions of code.
-** Init file may be placed in alternative locations, and other changes.
+** Face and variable settings can have comments in Customize.
+Customize now supports adding comments about your face and variable
+settings using a new menu entry. Comments for variables can also be
+assigned by calling `customize-set-(value|variable)' with a prefix
+argument.
-*** XEmacs now supports a `~/.xemacs/init.el' startup file. If
-it exists, XEmacs will prefer it over `.emacs' and `.emacs.el'. The
-file may be byte-compiled as `~/.xemacs/init.elc'.
+** New locations for early package hierarchies.
+XEmacs now locates the early package hierarchies at
+~/.xemacs/mule-packages/ and ~/.xemacs/xemacs-packages/. Previously,
+the early packages were located in ~/.xemacs/.
-If present, the `~/.xemacs/' directory may contain startup files for
-XEmacs packages that support it.
+** The `auto-save' library has been greatly improved.
+(This lets you group all your auto-save files into one directory, and
+is provided standardly with XEmacs. See `etc/sample.init.el',
+available on the Help menu, for more info on how to set it up.)
+Specifically, it now works under MS Windows, and it uses a completely
+reversible encoding (basically quoted-printable), so that all
+filenames (as well as non-filename buffers) are successfully handled
+regardless of any special characters in their names.
-NOTE: Under MS Windows, your home directory (i.e. the directory named
-`~') is specified by the HOME environment variable, and defaults to
-C:\. To set this variable, modify AUTOEXEC.BAT under Windows 95/98,
-or select Control Panel->System->Advanced->Environment Variables...
-under Windows NT/2000.
+** New variable `mswindows-alt-by-itself-activates-menu'.
+If you set this variable to nil then pressing and releasing the Alt
+key under MS Windows will no longer activate the menubar. The default
+is t. This is not to be confused with `menu-accelerator-enabled',
+which enables the use of Alt+<Letter> accelerators to invoke the
+menus.
+
+** The variable `kill-whole-line' now only takes effect interactively.
+
+(This variable controls the behavior of `kill-line'.) Although this
+is a departure from a previous behavior in the case of setting this
+variable `kill-whole-line' to t, it is almost certainly what has
+always been intended, and most likely the old way of doing things
+introduced bugs.
+
+** Other init-file-related changes.
*** Init file in your home directory may be called `.emacs.el'.
If both `.emacs' and `.emacs.el' exist, the latter file is the one
that is used.
-*** Much-improved sample init file.
-
-The sample init file, located in the `etc/' directory of the XEmacs
-installation, has been renamed from `sample.emacs' to `sample.init.el',
-and pretty much rewritten from scratch. (You can view it by selecting
-the menu item Help->Samples->View Sample init.el.) Many of the
-most-useful optional features in XEmacs have been enabled, and other
-features that are useful but may be annoying to some are present but
-commented out. There is also extensive documentation on how to add
-your own improvements to the init file and where to find more
-documentation elsewhere in XEmacs. The file has been specifically
-designed so that most people can simply make it their own init file by
-copying it to ~/.xemacs/init.el, and they will be satisfied with the
-results.
-
*** New command-line switches -user-init-file and -user-init-directory.
These can be used to specify alternate locations for what is normally
`-user-init-file ~<user>/.emacs -user-init-directory ~<user>/.xemacs',
whichever init file comes first.
-*** Custom file will move to ~/.xemacs/custom.el.
-
-Whereas customize settings were formerly stored in the regular init
-file, XEmacs now prefers them to be in a separate file
-`~/.xemacs/custom.el', completely under automatic control. This
-change goes with the migration of the init file, and XEmacs offers
-automatic migration upon startup.
-
-** Customize now supports adding comments about your face and variable
-settings using a new menu entry. Comments for variables can also be
-assigned by calling `customize-set-(value|variable)' with a prefix
-argument.

-is called interactively. Although this is a departure from a previous
-behavior in the case of setting this variable kill-whole-line to t,
-it is almost certainly what has always been intended, and most likely
-the old way of doing things introduced bugs.
-
** Etags changes.
*** In DOS, etags looks for file.cgz if it cannot find file.c.
-*** New option --ignore-case-regex is an alternative to --regex. It is now
-possible to bind a regexp to a language, by prepending the regexp with
-{lang}, where lang is one of the languages that `etags --help' prints
-out. This feature is useful especially for regex files, where each
-line contains a regular expression. The manual contains details.
