* 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 configuration 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.
(from the bin and libexec directories, respectively). The former is
no longer relevant, the latter is replaced by lisp (in vc-sccs.el).
