Release Notes: The focus of this release is the Game Engine, which has added a number of nice new features such as GLSL shaders, the capability of using multiple materials and UV maps, and multiple viewports, as well as a number of important fixes such as the return of the armature system. The core tools also have been improved, with subsurf-aware UV mapping, the addition of a live sculpting tool, set chaining, a number of Python script additions and improvements, and the addition of the Python Pose module, along with other Python improvements and fixes.
Release Notes: This release includes FreeStyle for NPR rendering. The paint system has been improved. Subsurface scattering support for the cycles rendering engine was added. Motion tracking speed and accuracy was improved. The compositor can now preview smaller regions of the image. Python defined node support has been added. An improved modelling tool, better Unicode support in the text editor and console, and a 3D printing toolset are now included. Over 260 bugs were fixed.
Release Notes: Fixes for over 80 bugs since 2.66 relating to sculpting, rigid-body physics, user interface, and the game engine.
Release Notes: This release contains long-awaited features like rigid body physics simulation, dynamic topology sculpting, and matcap display. Other new features include Cycles hair rendering, support for high pixel density displays, much better handling of premultiplied and straight alpha transparency, a vertex bevel tool, a mesh cache modifier, and a new SPH particle fluid. This release also includes over 250 bugfixes since the last release.
Release Notes: Over 40 bugs have been fixed since 2.65.
Release Notes: Cycles ray-tracer now does motion-blur. Support has been added for Open Shading Language. A rewritten bevel tool with curved edge support; the decimate modifier now supports UVs and Vertex Colors. This release includes many small improvements and over 200 bugfixes.
