This builds Emacs with Cairo drawing. As a side effect, it provides
support for built-in printing, when Emacs was built with GTK+.
+** New configure option --with-modules.
+This enables support for loading dynamic modules; see below.

** By default, Emacs no longer works on IRIX. We expect that Emacs
users are not affected by this, as SGI stopped supporting IRIX in
which specifies an alternative printing method which is faster when
few or no entries have changed.
+** Emacs can now load shared/dynamic libraries (modules) that expose a
+C interface. Such modules can provide additional functions or
+otherwise interact with Emacs just like Lisp code. Modules have to
+export a function `emacs_module_init' and conform to the API laid out
+in emacs-module.h. Modules are disabled by default and need to be
+enabled using the --with-modules configure flag. They are
+experimental and subject to change.
