The Blender 2.75a bug fix release addresses some urgent issues that popped in in the recently released Blender 2.75.
A couple of bug fixes were important enough to not leave in the 2.75 release, even though the next release is already expected in 5 weeks.
If you don't like boring bug fix logs, this is good to know at least:
- Game Engine would crash for Objects using velocity clamping
- Browsing render passes in Blender crashed.
For the rest, the full list.
