* Installation Changes in Emacs 24.3
-** The default toolkit has been changed to Gtk+ version 3.
+** The default X toolkit is now Gtk+ version 3.
If you don't pass `--with-x-toolkit' to configure, or if you use
`--with-x-toolkit=gtk' or `--with-x-toolkit=yes', configure will try
to build with Gtk+ version 3, and if that fails, try Gtk+ version 2.
You can explicitly require a specific version by passing
`--with-x-toolkit=gtk2' or `--with-x-toolkit=gtk3' to configure.
-** New configure option `--without-all' to disable additional features.

-depends on the graphical library.
-
** If the NEWTEXT arg to `replace-match' contains a substring "\?",
that substring is inserted literally even if the LITERAL arg is
non-nil, instead of causing an error to be signaled.
** `select-window' now always makes the window's buffer current.
It does so even if the window was selected before.
-** Docstrings starting with `*' no longer indicate user options.
-Only variables defined using `defcustom' are considered user options.
-The function `user-variable-p' is now an obsolete alias for
-`custom-variable-p'.
-
-** The return values of `defalias', `defun' and `defmacro' have changed,
-and are now undefined. For backwards compatibility, `defun' and
-`defmacro' currently return the name of the newly defined
-function/macro, but this should not be relied upon.
+** The function `x-select-font' can return a font spec, instead of a
+font name as a string. Whether it returns a font spec or a font name
+depends on the graphical library.
** `face-spec-set' no longer sets frame-specific attributes when the
third argument is a frame (that usage was obsolete since Emacs 22.2).
-** The arguments of `dbus-register-signal' are no longer just strings,
-but keywords or keyword-string pairs. The old argument list will
-still be supported for Emacs 24.x.
+** `set-buffer-multibyte' now signals an error in narrowed buffers.
** The CL package's `get-setf-method' function no longer exists.
Generalized variables are now part of core Emacs Lisp, and implemented
define a compatible replacement for `get-setf-method'. See the file
gv.el for internal details of the new implementation.
-** Spelling changes.
+** The arguments of `dbus-register-signal' are no longer just strings,
+but keywords or keyword-string pairs. The old argument list will
+still be supported for Emacs 24.x.
+
+** Miscellaneous name changes
Some Lisp symbols have been renamed to correct their spelling,
or to be more consistent with standard Emacs terminology.
**** robin-inactivate-hook -> robin-deactivate-hook
**** quail-inactivate-hook -> quail-deactivate-hook
-*** Renamed Lisp variables
+*** Renamed variables
**** follow-deactive-menu -> follow-inactive-menu

* Lisp changes in Emacs 24.3
-** New sampling-based Elisp profiler.
-Try M-x profiler-start, do some work, and then call M-x profiler-report.
-When finished, use M-x profiler-stop. The sampling rate can be based on
-CPU time or memory allocations.
-
** CL-style generalized variables are now in core Elisp.
`setf' is autoloaded; `push' and `pop' accept generalized variables.
You can define your own generalized variables using `gv-define-simple-setter',
`gv-define-setter', etc.
+** Emacs tries to macroexpand interpreted (non-compiled) files during load.
+This can significantly speed up execution of non-byte-compiled code,
+but can also bump into previously unnoticed cyclic dependencies.
+These are generally harmless: they will simply cause the macro calls
+to be left for later expansion (as before), but will result in a
+warning ("Eager macro-expansion skipped due to cycle") describing the cycle.
+You may wish to restructure your code so this does not happen.

+
** `defun' also accepts a (declare DECLS) form, like `defmacro'.
The interpretation of the DECLS is determined by `defun-declarations-alist'.
-** Minibuffer
+** New macros `setq-local' and `defvar-local'.
-*** `read-regexp' has a new argument HISTORY; the first argument PROMPT
+** Face underlining can now use a wave.
+
+** `read-regexp' has a new argument HISTORY; the first argument PROMPT
of `read-regexp' accepts a string ending with a colon and space, and its
second argument DEFAULTS can be a list of strings accessible via `M-n'
in the minibuffer ahead of other hard-coded useful regexp-related values.
*** New function `completion-table-subvert' to use an existing completion
table, but with a different prefix.
-** Debugger changes
+** Debugger
*** New error type and new function `user-error'.
These do not trigger the debugger.
*** New var `inhibit-debugger', automatically set to prevent accidental
recursive invocations.
-** Window changes
+** Window handling
-*** The functions `get-lru-window', `get-mru-window' and `get-largest-window'
-now accept a third argument to avoid choosing the selected window.
+*** New command `fit-frame-to-buffer' adjusts the frame height to
+fit the contents.
-*** Additional values recognized for option `window-combination-limit'.
+*** The command `fit-window-to-buffer' can adjust the frame height
+if the new option `fit-frame-to-buffer' is non-nil.
*** New macro `with-temp-buffer-window', similar to
`with-output-to-temp-buffer'.
*** `temp-buffer-resize-mode' no longer resizes windows that have been
reused.
-*** New command `fit-frame-to-buffer' adjusts the frame height to
-fit the contents.
-
-*** The command `fit-window-to-buffer' can adjust the frame height
-if the new option `fit-frame-to-buffer' is non-nil.
-
*** New option `switch-to-buffer-preserve-window-point' to restore a
window's point when switching buffers.
-*** New display action functions `display-buffer-below-selected',
-and `display-buffer-in-previous-window'.
+*** New display action alist entries `window-height' and `window-width'
+specify the size of new windows created by `display-buffer'.
+
+*** New display action alist entry `pop-up-frame-parameters', if
+non-nil, specifies frame parameters to give any newly-created frame.
*** New display action alist entry `inhibit-switch-frame', if non-nil,
tells display action functions to avoid changing which frame is
selected.
-*** New display action alist entry `pop-up-frame-parameters', if
-non-nil, specifies frame parameters to give any newly-created frame.
-
*** New display action alist entry `previous-window', if non-nil,
specifies window to reuse in `display-buffer-in-previous-window'.
-*** New display action alist entries `window-height' and `window-width'
-specify the size of new windows created by `display-buffer'.
+*** New display action functions `display-buffer-below-selected',
+and `display-buffer-in-previous-window'.
+
+*** The functions `get-lru-window', `get-mru-window' and `get-largest-window'
+now accept a third argument to avoid choosing the selected window.
+
+*** Additional values recognized for option `window-combination-limit'.
*** The following variables are obsolete, as they can be replaced by
appropriate entries in the `display-buffer-alist' function introduced
on others. The affected functions are acos, asin, tan, exp, expt,
log, log10, sqrt, and mod.

+** New fringe bitmap `exclamation-mark'.
-** Miscellaneous new functions:
+** Miscellaneous changes to special forms and macros
+
+*** `defun' and `defmacro' are now macros rather than special forms.
+
+*** `kbd' is now a function rather than a macro.
+
+** Miscellaneous new functions
+
+*** `set-temporary-overlay-map' sets up a temporary keymap that
+takes precedence over most other maps for a short while (normally one key).
*** `autoloadp' tests if its argument is an autoloaded object.
*** `posnp' tests if an object is a `posn'.
-*** `set-temporary-overlay-map' sets up a temporary keymap that
-takes precedence over most other maps for a short while (normally one key).
-
*** `system-users' returns the user names on the system.
