Ahoy! If possible, could you please update to the latest upstream, as the new version of qtile needs it. Thanks! John.
Provenpackager Notice Of Intent: As John wants it I'm planning to do this bump in a few days. If it shouldn't be done, speak now or forever hold your peace! (upstream doesn't actually have its changelog updated since 0.6, but I checked the git commit history and I don't see anything ragingly backwards-incompatible. The only other user is python-weasyprint which seems to be actively maintained and doesn't specify a top end on its cairocffi dependency).
