** 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:
+% defaults write org.gnu.Emacs FontBackend ns

* 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.
+++
** `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
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.
+
\f
* 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.
-** More packages look for ~/.emacs.d/<foo> additionally to ~/.<foo>.
+* More packages look for ~/.emacs.d/<foo> additionally to ~/.<foo>.
Affected files:
~/.emacs.d/timelog replaces ~/.timelog
~/.emacs.d/vip replaces ~/.vip
*** In VC directory mode, `L' lists the change log for the current VC
controlled tree in a window.
+*** In VC directory mode, `I' shows a log of changes that will be
+received with a pull operation.
+
*** `C-x v G' (globally) and `G' (in VC directory mode) ignores a file
under current version control system. When called with a prefix
argument, you can remove a file from the ignored file list.
+*** `cvs-append-to-ignore' has been renamed to `vc-cvs-append-to-ignore'
+because it is moved to vc-cvs.el.
+
** cl-lib
*** New macro cl-tagbody.
Tramp-using variants can still be used by enabling the eshell-tramp
module.
+** Package
+
+*** 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:
\f
* Lisp Changes in Emacs 24.4
++++
+** Functions that pop up menus and dialogs now work on all terminal types,
+including TTYs.
+This includes `x-popup-menu', `x-popup-dialog', `message-box',
+`yes-or-no-p', etc.
+
+The function `display-popup-menus-p' will now return non-nil for a
+display or frame whenever a mouse is supported on that display or
+frame.
+
+** New bool-vector set operation functions:
+*** `bool-vector-exclusive-or'
+*** `bool-vector-union'
+*** `bool-vector-intersection'
+*** `bool-vector-set-difference'
+*** `bool-vector-not'
+*** `bool-vector-subsetp'
+*** `bool-vector-count-matches'
+*** `bool-vector-count-matches-at'
+
** Comparison functions =, <, >, <=, >= now take many arguments.
** The second argument of `eval' can now be a lexical-environment.
