This is a development release leading toward 2.22.


 * GTK+ 2.22 is planned to be the last stable GTK+ 2.x release,
   to be released in parallel with GTK+ 3. It will not receive
   major feature work beyond API additions that are required
   to facilitate porting to GTK+ 3.

 * Installing this version will overwrite your existing
   copy of GTK+ 2.20. If you have problems, you'll need
   to reinstall GTK+ 2.20.

 * GTK+ 2.22 will be source and binary compatible with
   the GTK+ 2.20 series; however, the new API additions
   are not yet finalized, so there may be incompatibilities
   between this release and the final 2.22 release.

 * Bugs should be reported to

What is GTK+

GTK+ is a multi-platform toolkit for creating graphical user
interfaces. Offering a complete set of widgets, GTK+ is suitable for
projects ranging from small one-off tools to complete application

GTK+ has been designed from the ground up to support a range of
languages, not only C/C++. Using GTK+ from languages such as Perl and
Python (especially in combination with the Glade GUI builder) provides
an effective method of rapid application development.

GTK+ is free software and part of the GNU Project. However, the
licensing terms for GTK+, the GNU LGPL, allow it to be used by all
developers, including those developing proprietary software, without
any license fees or royalties.
