`--with-file-notification-no'. See below for file-notify features.
FIXME? This feature is not available for the Nextstep port. (?)
+** The configure option `without-compress-info' has been generalized,
+and renamed to `without-compress-install'. It now prevents compression
+of _any_ files during installation.
+
** The configure option --with-crt-dir has been removed.
It is no longer needed, as the crt*.o files are no longer linked
specially.
** Directories passed to configure option `--enable-locallisppath' are
no longer created during installation.
+** Emacs can be compiled with zlib support. If this library is present
+(which it normally is on most systems), the function
+`zlib-decompress-region' becomes available, which can decompress gzip-
+and zlib-format compressed data.

** Emacs for NS (OSX, GNUStep) can be built with ImageMagick support.
pkg-config is required to find ImageMagick libraries.
+** For OSX >= 10.5, the Core text based font backend from the Mac port is used.
+For GNUStep and OSX 10.4 the old backend is used.
+To use the old backend by default, do on the command line:

* Changes in Emacs 24.4
++++
+** Emacs now supports menus on text-mode terminals.
+If the terminal supports a mouse, clicking on the menu bar, or on
+sensitive portions of the mode line or header line, will drop down the
+menu defined at that position. Likewise, clicking C-mouse-2 or
+C-mouse-2 or C-mouse-3 on the text area will pop up the menus defined
+for those locations.
+
+If the text terminal does not support a mouse, you can activate the
+first menu-bar menu by typing F10, which invokes `menu-bar-open'.
+
+If you want the previous behavior, whereby F10 invoked `tmm-menubar',
+customize the option `tty-menu-open-use-tmm' to a non-nil value.
+(Typing M-` will always invoke `tmm-menubar', even if
+`tty-menu-open-use-tmm' is nil.)
+
** Key ? also describes prefix bindings like C-h.
++++
+** `cache-long-line-scans' has been renamed to `cache-long-scans'
+because it affects caching of paragraph scanning results as well.
+
+++
** `apropos-variable' is now `apropos-user-option'
`apropos-user-option' shows all user options while `apropos-variable'
** `initial-buffer-choice' can now specify a function to set up the
initial buffer.
+** The *Messages* buffer is created in a new major mode `messages-buffer-mode',
+and read-only. Code that might create the *Messages* buffer should
+call the function `messages-buffer' to do so and set the mode.
+
** `remember-notes' creates a buffer whose content is saved on kill-emacs.
You may think of it as a *scratch* buffer whose content is preserved.
In fact, it was designed as a replacement for *scratch* buffer and can
Also timers for blinking are stopped when no blinking is done, so Emacs does
not consume CPU cycles.
+** New command `frameset-to-register' is now bound to `C-x r f', replacing
+`frame-configuration-to-register'. It offers similar functionality, plus
+some enhancements, like the ability to restore deleted frames. Command
+`frame-configuration-to-register' is still available, but unbound.
+
+** The command `quail-help' is deleted. Use `C-h C-\'
+(`describe-input-method') instead.
+
+** The default value of `comment-use-global-state' is changed to t,
+and this variable has been marked obsolete.

* Editing Changes in Emacs 24.4
+** C-x TAB enters a transient interactive mode.
+You can then use the left/right cursor keys to move the block of text.
+
+** `tab-stop-list' is now implicitly extended to infinity by repeating
+the last step. Its default value is changed to nil which means a tab
+stop every `tab-width' columns.
+
** `split-window' is no longer a command, just a non-interactive function.
As a command it was a special case of `split-window-below', and as such
superfluous. After being reimplemented in Lisp, its interactive form
left, <right> always moves to the right, disregarding the surrounding
bidirectional context.
+** All register commands can now show help with preview.
+
** New command `kmacro-to-register' to store keyboard macros in registers.
** Shell Script mode
See `remember-data-directory' and `remember-directory-file-name-format'
for new options related to this function.

*** Ido has a manual now.
`f' (`image-next-frame') and `b' (`image-previous-frame') visit the
next or previous frame. `F' (`image-goto-frame') shows a specific frame.

When toggling, it restores the frame's previous window configuration.

- reprioritizing items by inputting a numerical priority;
- extensive customizability of operation and display, including numerous faces.
+The Todo mode user manual describes all commands and most user options.
To support some of these features, a new file format is used, which is
incompatible with the old format; however, you can convert old todo and done
item files to the new format on initializing the first new todo file, or at any

Tramp-using variants can still be used by enabling the eshell-tramp
module.

+*** The format of `archive-contents' files, generated by package
+repositories, has changed to allow a new (fifth) element, containing
+an associative list with extra properties.
+
+*** `describe-package' buffer uses the `:url' extra property to
+display a `Homepage' header, if it's present.
+
** New term.el option `term-suppress-hard-newline'.
** Obsolete packages:
** `visited-file-modtime' now returns -1 for nonexistent files.
Formerly it returned a list (-1 LOW USEC PSEC), but this was ambiguous
in the presence of files with negative time stamps.
+
+** The cars of the elements in `interpreter-mode-alist' are now treated
+as regexps rather than literal strings. Technically this is an
+incompatible change, but unless you are using interpreter-mode-alist
+for something (not just adding elements to it), it ought not to affect you.

+The function `display-popup-menus-p' will now return non-nil for a
