@jarednorman what's your oppinion on churnbuster?

I agree that the ChurnBuster integration should probably be removed.

I agree that the ChurnBuster integration should probably be removed.

Ok, we have a minor bumb to release now (and could put some notes about deprecated stuff in there and remove in the next round) and after we fixed the other stuff we can go for a major and remove / fix the remaining things.
