[pygtk] ANNOUNCE: PyGTK 2.12.1

[Johan Dahlin <jdahlin async com br>]

I am pleased to announce version 2.12.1 of the Python bindings for GTK;
This release includes various bug fixes, plugged memory leaks and a few new 
features.
Most prominently if built against python trunk it will no longer wakeup when
it is not necessary since we can avoid the timeout thanks to a newly added
API in Python. Thanks Guido!

The new release is available from ftp.gnome.org and its mirrors
as soon as its synced correctly:

Blurb:

GTK is a toolkit for developing graphical applications that run on
systems such as Linux, Windows and MacOS X. It provides a comprehensive set
of GUI widgets, can display Unicode bidi text.  It links into the Gnome
Accessibility Framework through the ATK library.

PyGTK provides a convenient wrapper for the GTK+ library for use in
Python programs, and takes care of many of the boring details such as
managing memory and type casting.  When combined with PyORBit and
gnome-python, it can be used to write full featured Gnome applications.

Like the GTK+ library itself PyGTK is licensed under the GNU LGPL, so is
suitable for use in both free software and proprietary applications.  It
is already in use in many applications ranging from small single purpose
scripts up to large full features applications.

This is a stable release and requires either GTK+ 2.8.x, 2.10.x or >= 2.12.0.

Bug reports, as always, should go to Bugzilla; check out
