* 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
+--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.
This disables most of the features that are normally enabled by default.
+---
** 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
may be useful.
+---
+** 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,
as it was confusingly-named and rarely useful.
overwriting "emacs" in the installation bin/ directory with a link
to emacs-VERSION.
+---
+** 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.

** Emacs uses libtinfo in preference to libncurses, if available.
(from the bin and libexec directories, respectively). The former is
no longer relevant, the latter is replaced by lisp (in vc-sccs.el).

+interface instead of the default, X11.

* Startup Changes in Emacs 24.3
explicitly to install ImageMagick image types; that function is called
automatically at startup, or when customizing a relevant imagemagick-
option.
-
++++
*** Setting `imagemagick-types-inhibit' to t now disables the use of
ImageMagick to view images. You must call imagemagick-register-types
afterwards if you do not use customize to change this.
-
++++
*** The new variable `imagemagick-enabled-types' also affects which
ImageMagick types are treated as images. The function
`imagemagick-filter-types' returns the list of types that will be
treated as images.
-
+---
*** Images displayed via ImageMagick now support transparency and the
:background image spec property.
of the fatal signal, and a short backtrace on platforms like glibc
that support backtraces.
-** `message-log-max' now defaults to 1000, not 100.
-
---
** If your Emacs was built from a bzr checkout, the new variable
`emacs-bzr-version' contains information about the bzr revision used.
---
*** Fullscreen and frame parameter fullscreen is supported.
---
-*** A file dialog is used when open/saved is done from the menu/toolbar.

-flymake-warning-bitmap.
+See `flymake-fringe-indicator-position', `flymake-error-bitmap' and
+`flymake-warning-bitmap'.
** Follow mode

the FFAP prompt. The default is now '("ftp").
+** Generic-x

* Changes in Emacs 24.3 on non-free operating systems
-** New configure.bat options on MS-Windows:
-
-*** --without-libxml2 omits support for libxml2, even if its presence
-is detected.
++++
+** On MS Windows, you can pass --without-libxml2 to configure.bat to omit
+support for libxml2, even if its presence is detected.
** When invoked with the -nw switch to run on the Windows text-mode terminal,
Emacs now supports mouse highlight, help-echo (in the echo area), and
-mouse-autoselect-window.
+`mouse-autoselect-window'.
+
+** Two new functions are available in Cygwin builds:
+`cygwin-convert-path-from-windows' and `cygwin-convert-path-to-windows'.
+These functions allow Lisp code to access the Cygwin file-name mapping
+machinery to convert between Cygwin and Windows-native file names.
-** On MS-Windows Vista and later Emacs now supports symbolic links.
