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
-disable them by specifying:
+disable them by customizing `gutter-buffers-tab-visible-p', or by
+placing this in your .emacs:
- (set-specifier default-gutter-visible-p nil)
+ (set-gutter-element-visible-p default-gutter-visible-p 'buffers-tab nil)
-in your `.emacs'. You can change the location of the gutter with

+
+** 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.
is now equivalent to
-user-init-file ~<user>/.emacs -user-init-directory ~<user>/.xemacs.
+** Init file may be called .emacs.el.
+
+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 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
+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.
-** Pixel-based scrolling has been implemented.
+** Pixel-based scrolling has been implemented.
By default this will attempt to scroll in increments equal to the
-height of the default face. Set `window-pixel-scroll-increment' to
+height of the default face. Set `window-pixel-scroll-increment' to
modify this behaviour.
+** Operation progress can be displayed using graphical widgets.
+See `lprogress-display' for details. This support has been switched
+on by default for font-lock and some web browsing functions. If you
+do not like this behaviour set `progress-display-use-echo-area'.
+
** Etags changes.
+** The PostgreSQL Relational Database Management System is now supported.
+It is now possible to build XEmacs so that the programming interface
+to the PostgreSQL RDBMS (libpq) is available in XEmacs Lisp.
+Supported versions of PostgreSQL are 6.5.3 (earlier versions may work,
+but have not been tested) and 7.0-beta1.
+
*** 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
between `temacs' and `xemacs'.
This is all very experimental, though. Configure with `--pdump' to
-try testing it. NOTE: it is expected that `make' will fail after
-dumping `xemacs.dmp'. This is because Makefiles have not yet been
-modified to not expect `temacs' producing an `xemacs' executable. You
-can try it out by simply running `src/temacs'. If it starts without
-failure, the portable dumping worked.

-it. Nag, nag.

** Much effort has been invested to make XEmacs Lisp faster:
buffer. As a side effect subwindow support now works once again.
All of this is still fairly experimental and there is no

global obarray. `keywordp' used to wrongly return t in both cases
above.
+** New variables `this-command-properties' and
+`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.
