-XEmacs is a branch version of Emacs.  It was first called Lucid Emacs,
-and was initially derived from a prerelease version of Emacs 19.  In
-this FAQ, we use the name ``Emacs'' only for the official version.
-
-Emacs and XEmacs each come with Lisp packages that are lacking in the
-other.  The two versions have some significant differences at the Lisp
-programming level.  Their current features are roughly comparable,
-though the support for some operating systems, character sets and
-specific packages might be quite different.
-
-Some XEmacs code has been contributed to Emacs, and we would like to
-use other parts, but the earlier XEmacs maintainers did not always
-keep track of the authors of contributed code, which makes it
-impossible for the FSF to get copyright papers signed for that code.
-(The FSF requires these papers for all the code included in the Emacs
-release, aside from generic C support packages that retain their
-separate identity and are not integrated into the code of Emacs
-proper.)

+XEmacs last released a new version on January 30, 2009, and it lacks
+many important features that exists in Emacs.  In the past, it was not
+uncommon for Emacs packages to include code for compatibility with
+XEmacs.  Nowadays, although some packages still maintain such
+compatibility code, several of the more popular built-in and third
+party packages have either stopped supporting XEmacs or was developed
+exclusively for Emacs.
 
 If you want to talk about these two versions and distinguish them,
 please call them ``Emacs'' and ``XEmacs.''  To contrast ``XEmacs''
