Some new things:
Physics collisions dont work if objects are in a group. Add some boxes to a group from the demo and try to collide with them. Youll walk through them.
When you try to rotate an object with MMB (double click to center around it) and the object is grouped or parented the rotate is off the center.
The update on the right panel is slow, when you add an object or rename the name.
No crashes so far.
