New users wishing to develop Python applications using GTK+ are recommended to use the GObject-Introspection features available in PyGObject.
Existing authors of PyGTK applications are also recommended to port their applications to PyGObject to take advantage of new features appearing in GTK-3 and beyond. More information on PyGObject and GObject-Introspection can be found at http://live.gnome.org/PyGObject.
PyGTK-2.24 will be the final major release of PyGTK. Additional bug-fix releases may appear when necessary to maintain compatibility and stability with the GTK-2.24 series.
As usual, sources can be fetched from here. Check out the release announcement and full list of changes.

意思大概就是 PyGTK-2.24是最后一个主要的更新版本。大家如果想继续使用Python开发GTK＋程序，就建议使用PyGObject库，使用PyGObject库可利用GTK＋3的一些新特性。
不知道深度有没有打算从PyGTK移植到PyGObject，不过，这些过时的库肯定会成为软件发展的瓶颈。
