Released PyGTK 2.4.0, gnome-python 2.6.0 and PyORBit 2.0.1. This marks a major milestone for the Gtk+ and Gnome python bindings.
PyGTK now supports all the beauties of GtkUIManager and GtkFileChooser. So start updating your code!
Over the last few days I've been writing bindings for the "new" nautilus extension API introduced a while ago. It can be checked out from gnome cvs, the module name is nautilus-python. I'd say that its a lot nicer than the old bonobo/corba based one. I also wrote a couple of examples, which can be found here I specially like the "Use as background image" context menu plugin. I wonder if we're going to see a new g-scripts site now..
