I released d-feet 0.3.1 today. This is an unstable release and the first release based on Gtk+3, gobject-introspection and gdbus. A lot of code changed and I also removed some parts. If you are a dbus user, please test the release and give some feedback. You can find more information about d-feet on https://live.gnome.org/DFeet/.
Many thanks to Martin Pitt and John Palmieri for testing, suggestions and feedback!
