By For Linux x86-64 Python 2.5,new modifers were added, a couple of composite nodes were added, and a revamp of the old mesh primitives was done.
Features：
FFMPEG is now included in the Windows builds
Sculpt and MultiRes bug fixes and improvements
Subsurface Scattering is a new material option
There have been a large number of python script additions and updates, as well as API improvements
Two new Composite nodes have been added: Gamma and Bright/Contrast
Two new Modifiers: Smooth and Cast
The Action and NLA editors have now better control over visible channels. A new constraint was added, and a "preview range" option was added.
Blender now is 64-bits safe again. That safety is on two different levels.
The Bullet physics engine has had some changes which should give better reproducibility and precision/quality for physics simulations.
The mesh primitives have been revisited, improving their usability and pushing them a little beyond their previous state. This includes the addition of a new Torus primitive!
