* Installation Changes in Emacs 24.3
----
-** The default toolkit has been changed to Gtk+ version 3.
-If you don't pass --with-x-toolkit to configure or if you pass

+** The default X toolkit is now Gtk+ version 3.

+`--with-x-toolkit=gtk' or `--with-x-toolkit=yes', configure will try

You can explicitly require a specific version by passing
---with-x-toolkit=gtk2 or --with-x-toolkit=gtk3 to configure.

+** New configure option `--enable-link-time-optimization', to utilize
an appropriate feature provided by GCC since version 4.5.0.
----
-** New configure option '--enable-gcc-warnings', intended for developers.
-If building with GCC, this enables compile-time checks that warn about
-possibly-questionable C code. On a recent GNU system there should be
-no warnings; on older and on non-GNU systems the generated warnings

+** New configure option `--without-all' to disable most of the optional
+features (image support, etc.) that are normally enabled by default.

+** New configure option `--enable-gcc-warnings' (for developing/debugging
+Emacs). If building with GCC, this enables compile-time checks that
+warn/give errors about possibly-questionable C code. On a recent GNU
+system there should be no warnings; on older and on non-GNU systems
+the results may be useful to developers.

+** The configure option `--enable-use-lisp-union-type' has been
+renamed to `--enable-check-lisp-object-type', as the resulting
Lisp_Object type no longer uses a union to implement the compile time
check that this option enables.
----
-** The configure option '--disable-maintainer-mode' has been removed,
+** The configure option `--disable-maintainer-mode' has been removed,
as it was confusingly-named and rarely useful.
----
+** The configure options `--program-prefix', `--program-suffix', and
+`--program-transform-name' apply to more than just the installed
+binaries. Now they also affect the man pages, icons, and the
+etc/emacs.desktop file; but not the info pages, since this would break
+links between the various manuals.
+
** You can use `NO_BIN_LINK=t make install' to prevent the installation
overwriting "emacs" in the installation bin/ directory with a link
-to emacs-VERSION.
+to "emacs-VERSION".
----
** Emacs uses libtinfo in preference to libncurses, if available.
----
** On FreeBSD and NetBSD, configure no longer adds /usr/local/lib and
/usr/pkg/lib to the linker search path. You must add them yourself if
you want them.
----
-** On Mac OS X, configure no longer automatically adds the Fink /sw
-directories to the search path. You must add them yourself if you want them.
-
----
-** The standalone scripts rcs-checkin and vcdiff have been removed
+** The standalone scripts `rcs-checkin' and `vcdiff' have been removed
(from the bin and libexec directories, respectively). The former is
no longer relevant, the latter is replaced by lisp (in vc-sccs.el).
----
-** The native Windows user interface is available for Cygwin. Passing
---with-w32 will configure a Cygwin emacs to use the Windows user
-interface instead of the default, X11.

automatically loaded, so that the documentation can be shown
correctly. To disable this, set `help-enable-auto-load' to nil.
----
*** `C-h f' now reports previously-autoloaded functions as "autoloaded",
even after their associated libraries have been loaded (and the

ImageMagick types are treated as images. The function
`imagemagick-filter-types' returns the list of types that will be
treated as images.

-+++
-** `C-x C-q' is now bound to the new minor mode `read-only-mode'.
-This minor mode replaces `toggle-read-only', which is now obsolete.
+*** New option `server-auth-key' specifies a shared server key.

that support backtraces.
----

-+++
-** New variable `create-lockfiles' specifies usage of lockfiles.

+** In the buffer made by `M-x report-emacs-bug', the `C-c m' binding
+has been changed to `C-c M-i' (`report-emacs-bug-insert-to-mailer').
+The previous binding, introduced in Emacs 24.1, was a mistake, because
+`C-c LETTER' bindings are reserved for user customizations.

-+++
*** Non-regexp Isearch now performs "lax" space matching.
Each sequence of spaces in the supplied search string may match any

+*** New binding `M-g TAB' for `move-to-column'.
+
+*** `M-g TAB' (`move-to-column') prompts for a column number if called
+interactively with no prefix arg. Previously, it moved to column 1.

M-x delete-trailing-whitespace should delete trailing lines at the end
of the buffer. It defaults to t.

+* Changes in Specialized Modes and Packages in Emacs 24.3
-** CL
+** Common Lisp emulation (CL)
*** CL's main entry is now (require 'cl-lib).
-`cl-lib' is like the old `cl' except that it uses the namespace cleanly,
-i.e. all its definitions have the "cl-" prefix (and internal definitions use
-the "cl--" prefix).

-If `cl' provided a feature under the name `foo', then `cl-lib' provides it
-under the name `cl-foo' instead, with the exceptions of the few definitions
-that had to use `foo*' to avoid conflicts with pre-existing Elisp entities,
-which have not been renamed to `cl-foo*' but just `cl-foo'.

-The old `cl' is now deprecated and is just a bunch of aliases that

+The old `cl' is now deprecated and is mainly just a bunch of aliases that
+provide the old, non-prefixed names. Some exceptions are listed below:
*** `cl-flet' is not like `flet' (which is deprecated).
Instead it obeys the behavior of Common-Lisp's `flet'.
+In particular, in cl-flet function definitions are lexically scoped,
+whereas in flet the scoping is dynamic.
*** `cl-labels' is slightly different from `labels'.
-The difference is that it relies on the `lexical-binding' machinery (as opposed
-to the `lexical-let' machinery used previously) to capture definitions in
-closures, so such closures will only work if `lexical-binding' is in use.

+
+*** `cl-letf' is not exactly like `letf'.
+The only difference is in details that relate to some deprecated usage
+of `symbol-function' in place forms.
*** `progv' was rewritten to use the `let' machinery.
-A side effect is that vars without corresponding value are bound to nil
-rather than making them unbound.

+changes in context diffs.
-*** Non-option variables are never matched in `customize-apropos' and

+* Lisp Changes in Emacs 24.3
** 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.
+
+** 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.
** `defun' also accepts a (declare DECLS) form, like `defmacro'.
The interpretation of the DECLS is determined by `defun-declarations-alist'.
+** New macros `setq-local' and `defvar-local'.

+compatibility with existing code, if the class is omitted only a
+warning is issued.
+
+**** New specialized reader for pulling in classes and signaling errors
+without evaluation of suspicious code.

+**** All slots that contain objects must have a :type. Slots with lists
+of objects must use a new type predicate for a list of an object type.
