I have a 100d a2200. I downloaded "a2200-100d-1.1.0-2299-full_ALPHA" yesterday (22 Nov) from the autobuild server. It starts up fine in play mode, but when I switch to shoot mode, the lens comes out and the camera switches off. I extracted the full zip over the old version, so it's not that.
Anyway, I have gone back to the non-autobuild version which works.
