GTK+-2.3.0 released [unstable]

[Owen Taylor <otaylor redhat com>]

GTK+-2.3.0 is now available for download at:

 ftp://ftp.gtk.org/pub/gtk/v2.3/

gtk+-2.3.0.tar.bz2   md5sum: e3336aa41e440755543cb6532bec9938  
gtk+-2.3.0.tar.gz    md5sum: 83a5c6351797da3f2ef33e78408d8e6e  

This is the first development release loading up to GTK+-2.4. 
This release contains a number of major new widgets and capabilities
including: an action based menu system, a replacement for
GtkFileSelector, and a new unified GtkComboBox widget that replaces both
GtkOptionMenu and GtkCombo.

Special thanks on this release go to Marco Pesenti Gritti for testing
out the new widgets and menu system in Epiphany and providing plentiful
feedback. We hope many more people will follow his lead.

Notes:

 * This is unstable development release. 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+-2.4 will be source and binary compatible with
   the GTK+-2.2.x series; however, the new API additions
   in GTK+-2.3.0 are not yet finalized, so there are likely
   incompatibities between this release and the final
   2.2 release.

 * Remaining API issues for GTK+-2.4 can be found with following
   bugzilla query:
   
    http://bugzilla.gnome.org/buglist.cgi?product=gtk%2b&target_milestone=2.4+API+Freeze&bug_status=NEW&bug_status=ASSIGNED&bug_status=REOPENED

 * Bugs should be reported to http://bugzilla.gnome.org.
   
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
suites.

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.
