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.
+
+** You can now set the variable `kill-whole-line' to `always', which
+makes `kill-line' (C-k) delete the entire line always, not just when
+the cursor is at the beginning of the line. This behavior, as well as
+the existing kill-whole-line behavior, now only take 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.
+
+The new function `historical-kill-line' ignores the `kill-whole-line'
+setting and always gives the historical behavior of only killing to
+the end of the line. This function is bound to Sh-C-k, so that the
+kill to end of line behavior is available, even when `kill-whole-line'
+has been customized.
+
+** 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.
+
** Interactive searching and matching case improvements.
Case sensitiveness in searching operations is normally controlled by
** 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

+
+** 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.
** 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,
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.

** Mail spool locking now works correctly.
XEmacs has always come with a little auxiliary program, movemail,
binary kit, set the `mail-lock-method' variable at startup, or the
EMACSLOCKMETHOD environment variable.
+** Init file will move to ~/.xemacs/init.el.
+
+If `~/.xemacs/init.el' exists, XEmacs will prefer it over `~/.emacs'
+as an init file. The file may be byte-compiled as
+`~/.xemacs/init.elc'.
+
+Future versions of XEmacs will stop supporting `~/.emacs' as an init
+file. XEmacs offers automatic migration upon startup.
+
+** 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.
+
+** Init file may be called .emacs.el.
+
+For the time being, like in GNU Emacs 20.4 and on, you can now name
+the XEmacs init file `.emacs.el'. Formerly the name had to be
+`.emacs'. If you use the name `.emacs.el', you can byte-compile the
+file in the usual way.
+
+If both `.emacs' and `.emacs.el' exist, the latter file is the one
+that is used.
+
** 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.
Moreover, -user <user> (which used to only work in unpredictable ways)
-is now equivalent to
--user-init-file ~<user>/.emacs -user-init-directory ~<user>/.xemacs.

+file comes first.
** New variable `mswindows-meta-activates-menu'.
-If you set this variable to nil then pressing the Alt key under
-MS-Windows will no longer activate the menubar. The default is t.
+If you set this variable to nil then pressing and releasing the Alt

+do not like this behavior set `progress-feedback-use-echo-area'.

+** The PostgreSQL Relational Database Management System is now supported.
+It is now possible to build XEmacs so that the programming interface

+`last-command-properties' are now available for communication between
+consecutive commands. Commands should use these to communicate with
+the pre/post-command hooks, subsequent commands, wrapping commands,
+etc. in preference to looking at and/or setting `this-command'.
+
+** New functions `add-one-shot-hook' and `add-local-one-shot-hook' make
+it possible to add a "one-shot" hook, which is to say a hook that runs
+only once, and automatically removes itself after the first time it
+has run.
+
+** The descriptor that specifies the text of a menu item can now be an
+evaluated expression. This makes this descriptor parallel with
+others, which can also be expressions.
