This list is out of date. Query bugzilla.gnome.org for an up to date list. Things to do for the gtk 2.0 based release - fix up threading to work with GObject/GSignal/GClosure. See the THREADS file for more info on what is required. - Implement a new PyGtkTreeModel GObject type that can be the base for new tree models defined in Python. Need to look at how the GtkTreeIter->tree_node lifetime is handled, as it doesn't look like anything is called to let us know that that data should be unrefed.
