The Blender Foundation has released Blender 2.62. Most of features were updated and some new were added, including render layers and passes, multi GPU rendering and selection of GPU device, improved sampling for complex environment maps, border rendering, BVH caching for faster rendering of camera fly-throughs, and new shading nodes for color correction and a checkerboard texture node. UV tools have now an advanced interactive stitch tool, to align and join together UV islands. Version 2.62 updates Blender’s Boolean operations, implementing the faster, more stable Carve library, and adds a new Remesh modifier for converting a mesh to uniform quads. This update also fixes more than 200 bugs.
Some of key features and updates:
Cycles render engine– now with the latter gaining support for render layers and passes, and multi-GPU rendering
Remesh modifier- tool for generating new mesh topology based on an input surface
Collada– a Second Life compatibility option was added for exporting armatures, along with a number of other fixes related to transformations and armatures
Motion Tracking– support for object tracking has been added
"Carve" Booleans- now uses the Carve library, which should give much improved results
