+** Shifted motion keys now select text by default.
+
+You can turn this off by setting `shifted-motion-keys-select-region'

-** Shifted motion keys now select text by default.  You can turn this
-off by setting `shifted-motion-keys-select-region' to nil.
+** ~/.xemacs/init.el is now the preferred location for the init file.

 
 

-** 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'.
+*** 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'.

 
 

-** The variable `kill-whole-line' now only takes effect when kill-line
-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.
+If present, the `~/.xemacs/' directory may contain startup files for
+XEmacs packages that support it.

 
 

-** The help buffers created by the plethora of C-h commands now
-contain hyperlinks.
+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.

 
 

-** 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
-of `modeline-scrolling-method' for more information.
+*** Custom file will move to ~/.xemacs/custom.el.

 
 

-** XEmacs menus now have accelerators by default.  If a menu item does
-not have an accelerator specified, one is created dynamically, using
-numbers 1-9 and letters.
+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.

 
 

-** Interactive searching and matching case improvements.
+** Much-improved sample init.el, showing how to use many useful features.

 
 

-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
-uppercase characters, the searching is forced to be case-sensitive,
-`case-fold-search'.
+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.

 
 

-The new behavior affects all functions performing interactive
-searches, like `zap-to-char', `list-matching-lines', `tags-search'
-etc.  The incremental search facility has always behaved that way.
+** XEmacs support for menu accelerators has been much improved.

 
 

-** Incremental search will now highlight all visible matches, making
-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.
+It now works properly under MS Windows, for example.  To enable
+accelerators, set `menu-accelerator-enabled' to `menu-force'.  Menus
+now have accelerators by default, currently on the first letter of the
+menu item unless another letter was indicated as the accelerator using
+%_ in the menu string.  These %_ specifications are automatically
+removed when displaying the menu item, and are handled correctly in
+functions such as `normalize-menu-item-name'.  Some auto-generated
+menus will have accelerators added dynamically, using numbers 1-9 and
+letters; to add this feature yourself, use the Lisp command
+`submenu-generate-accelerator-spec' in a menu filter.  The feature
+`menu-accelerator-support' has been added so that packages can check
+whether this support exists.

 
 

-** The "coding systems" feature now works even in an XEmacs compiled
-without international (Mule) support.  This means that for example
-XEmacs can recognize newline convention used by the file you are
-editing.
+** Default menubar improvements.

 
 

-** You can now use the 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:
+*** Default menubar has many new commands and better organization.

 
 

-   (set-gutter-element-visible-p default-gutter-visible-p 'buffers-tab nil)
+The default menubar has been extensively reorganized.  Many more
+commands are available, and they are more logically organized.  The
+Options menu, in particular, has been significantly expanded, and almost
+everything on the new Cmds menu is new. (Much of the useful
+functionality from the `big-menubar' package has been imported.)

 
 

-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.
+*** The font-menu is now available under MS Windows.

 
 

-** 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.
+** Dialog box improvements, including a real file dialog box.

 
 

-** 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.
+*** XEmacs now has a proper file dialog box under MS Windows (and GTK)!
+This will appear whenever you select a menu item that requires a file
+as an argument.

 
 

-** 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.
-
-** 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
-rectangle, and `clear-rectangle', which filled even empty lines up to
-the left side.  All functions have been rewritten to avoid inserting
-unwanted spaces, and an optional prefix now allows them to behave the
-old way.
+*** 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.

 
 

-Also, the behavior of `string-rectangle' is now compliant with
-`pending-delete-mode': if this mode is active, then the string
-replaces the region rectangle.  Otherwise, the command does not delete
-or overwrite any existing text.  For those who want that feature but do
-not use pending-delete-mode, a new function, `replace-rectangle', is
-available.
+*** Keyboard traversal now works correctly in MS Windows dialog boxes.

 
 

-As a side effect, the FORCE argument to `move-to-column' now
-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 Search dialog box available from Edit->Find...
+However, it's very experimental and needs a lot of work.

 
 

-** 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.
+** New buffer tabs.

 
 

-** XEmacs now locates the early package hierarchies at
-~/.xemacs/mule-packages/ and ~/.xemacs/xemacs-packages/.  Previously,
-the early packages were located in ~/.xemacs/.
+You can now use buffer tabs to switch between buffers.

 
 

-** 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.
+The tabs are located between the toolbar and the uppermost window, in
+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:

 
 

-Use (make-indirect-buffer BASE-BUFFER NAME) to make an indirect buffer
-named NAME whose base is BASE-BUFFER.  If BASE-BUFFER is itself an
-indirect buffer, its base buffer is used as the base for the new
-buffer.
+   (custom-set-variables '(gutter-buffers-tab-visible-p nil))

 
 

-You can make an indirect buffer current, or switch to it in a window,
-just as you would a non-indirect buffer.
+You can change the location of the gutter using the menu item
+`Options->Display->Default Gutter Location' or with (e.g.)

 
 

-The function `buffer-base-buffer' returns a buffer's base buffer or
-nil, if given an ordinary (non-indirect) buffer.  The function
-`buffer-indirect-children' returns a list of the indirect children of
-a base buffer.
+   (custom-set-variables '(default-gutter-position 'left))

 
 

-** 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.
+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.

 
 

-The new primitives available for this purpose are functions named
-`user-name-completion' and `user-name-all-completions'.
+** There is a new MS Windows installer, netinstall, ported from Cygwin.

 
 

-** XEmacs can now play sound using Enlightenment Sound Daemon (ESD).
-It will try NAS first, then ESD, then playing native sound directly.
+Nearly complete automation of the XEmacs install process from
+ftp.xemacs.org.  Includes selection of Lisp packages to install, etc.

 
 

-** X-Face support is now available under MS-Windows.
-If an X-Face library built under MS-Windows is available then XEmacs
-will use this at build time.
+** 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
+just like under Unix, and expect to get correct results regardless of the
+shell you are using (e.g. CMD.EXE, bash from Cygwin, etc.).  For example,
+the following command:
+
+M-x grep '<<<<<<<' *.c
+
+should work as intended.

 
 

-** The font-menu is now available under MS-Windows.
+** Printing support now available under MS Windows.

 
 

-** MS-Windows support for selection is now much more robust.
+The File->Print... menu item pretty-prints using the standard MS
+Windows printing facilities.  Unfortunately it's still rather
+experimental.  There is a separate `msprinter' device tag for MS
+Windows printers, and so you can control the way that faces appear on
+the printer by using this tag to specify device-specific face
+settings.
+
+** Selection improvements.
+
+*** Kill and yank now interact with the clipboard 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.

-Like in GNU Emacs 20.4 and on, you can now name the XEmacs init file

-be `.emacs'.  If you use the name `.emacs.el', you can byte-compile
-the file in the usual way.
+*** MS Windows 1251 code page now supported.

 
 

-If both `.emacs' and `.emacs.el' exist, the latter file is the one
-that is used.
+It's available as coding system `windows-1251'.

 
 

-*** New command-line switches -user-init-file and -user-init-directory.
-These can be used to specify alternate locations for what is normally
-~/.emacs and ~/.xemacs.
+*** Czech, Thai, Cyrillic-KOI8, Vietnamese, Ethiopic now supported.

 
 

-Moreover, the `-user <user>' command-line option (which used to only
-work in unpredictable ways) is now equivalent to `-user-init-file
-~<user>/.xemacs/init.el -user-init-directory ~<user>/.xemacs', or

+*** Proper support for words in Latin 3 and Latin 4.

 
 

-*** Custom file will move to ~/.xemacs/custom.el.
+The appropriate characters in Latin 3 and Latin 4 character sets are

-Whereas customize settings were formerly stored in the regular init

-menus.

+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.
+
+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 of `modeline-scrolling-method' for more
+information.
+
+** The mouse wheel under MS Windows now functions correctly.
+
+It scrolls the XEmacs window under the pointer, not the selected
+window.
+
+** 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.
+
+*** 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
+uppercase characters, the searching is forced to be case-sensitive,
+`case-fold-search'.
+
+The new behavior affects all functions performing interactive
+searches, like `zap-to-char', `list-matching-lines', `tags-search'
+etc.  The incremental search facility has always behaved that way.
+
+** 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
+rectangle, and `clear-rectangle', which filled even empty lines up to
+the left side.  All functions have been rewritten to avoid inserting
+unwanted spaces, and an optional prefix now allows them to behave the
+old way.
+
+Also, the behavior of `string-rectangle' is now compliant with
+`pending-delete-mode': if this mode is active, then the string
+replaces the region rectangle.  Otherwise, the command does not delete
+or overwrite any existing text.  For those who want that feature but do
+not use pending-delete-mode, a new function, `replace-rectangle', is
+available.
+
+As a side effect, the FORCE argument to `move-to-column' now
+understands the special value `coerce', which means that the line
+should not be filled if it is too short to reach the desired column.
+
+** 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'.
+
+** 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.
+
+Use (make-indirect-buffer BASE-BUFFER NAME) to make an indirect buffer
+named NAME whose base is BASE-BUFFER.  If BASE-BUFFER is itself an
+indirect buffer, its base buffer is used as the base for the new
+buffer.
+
+You can make an indirect buffer current, or switch to it in a window,
+just as you would a non-indirect buffer.
+
+The function `buffer-base-buffer' returns a buffer's base buffer or
+nil, if given an ordinary (non-indirect) buffer.  The function
+`buffer-indirect-children' returns a list of the indirect children of
+a base buffer.

+*** Init file in your home directory may be called `.emacs.el'.
+
+Like in GNU Emacs 20.4 and on, you can now name the XEmacs init file

+be `.emacs'.  If you use the name `.emacs.el', you can byte-compile
