GTK+-2.1.0 released [unstable]

GTK+-2.1.0 is now available for download at:

This is the first development release loading up to GTK+-2.2. The
major change as compared to the stable GTK+-2.0.6 is support for
multiple displays and multiple screens in GDK, although there are
numerous minor changes as well.


 * This is unstable development release. While it has had
   fairly extensive testing, there are certainly plenty of bugs
   remaining to be found. This release should not be used
   in production.

 * Installing this version will overwrite your existing
   copy of GTK+-2.0. If you have problems, you'll need
   to reinstall GTK+-2.0.6.

 * GTK+-2.2 will be source and binary compatible with
   the GTK+-2.0.x series; however, the new API additions
   in GTK+-2.1.0 are not yet finalized, so there may
   be incompatibities between this release and the final
   2.2 release.

 * Remaining API issues for GTK+-2.2 can be found with following
   bugzilla query: 

 * This release exposes a bug in libgnomeui where libgnomeui
   was creating a widget of type GtkWidget instead of a derived
   class; to fix this, upgrade to libgnomeui-2.1.0.

 * GTK+ looks for theme engines in a version dependent directory, 
   so you'll need to reinstall any theme engines you want to use.

 * 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
pdevelopers, including those developing proprietary software, without
any license fees or royalties.
