I've just released ArduPlane 2.65
This is what is known in the free software community as a "brown paper bag" release, because the developer (that's me) thinks he should hide his head in a brown paper bag out of sheer embarrassment.
Steven G noticed that my fix for stick mixing in CIRCLE mode in 2.64 broke STABILISE mode. When I test flew 2.64 I tested FBWA, but not STABILISE mode!
So the only change in 2.65 is to fix that. My apologies for the 2.64 release!
