LetterRip writes "Googles Summer of Code has born fruit with the Blender 2.40 release. Thanks to their support and the hard work of the coders they supported Blender has fluid dynamics simulation done by Nils Thuerey, a powerful inverse kinematics system done by Brecht Van Lommel, and much improved boolean tools done by Marc Freixas. Of course Blender has had a huge number of improvements aside from the work supported by Google. The animation system got a complete rewrite by Ton Roosendaal, as well as other major improvements like flive UV unwrapping LSCM, and a Modifier stack system. It also has seen greatly improved ease of use since the last Slashdot announcement addressing all of the complaints raised- things like 3d manipulators, full undo system, etc. There is also a quick start guide for new users, and nice video and written tutorials on new features and a fairly up to date manual."
