Rotation Modes Bugfix:

Browse Source 
Animating rotations using different rotation modes should now work more often than before. 

Previously, quaternion and axis-angle values were stored in the same variable in DNA, but that was causing problems with other animation curves overwriting the values and causing the rotations to not work as expected. 

There are still some issues, but I'll track those down later tonight
