The Blender Foundation has finally released new Blender 2.63. This release was focused on integrating and stabilizing the long awaited BMesh modelling system, which has full support for N-sided polygons and many new modelling tools. New tools include Dissolve, Inset, Bridge, Vertex Slide, Vertex Connect, Bevel, and improved versions of Knife, Subdivide and Rip. This release was mainly focused on stabilizing BMesh, but also includes 150 fixes for bugs that existed in previous releases.
Key updates:
BMesh - the new Blender mesh system with full support for N-sided polygons instead of only triangles and quads
Cycles Render – Among the features added in this release are support for a panoramic camera, mirror ball environment textures, and float precision textures. Also new are render layer mask layers, a shadow render pass, ambient occlusion, and viewport display of background images and render layers.
Sculpt Hiding - Portions of the mesh can now be hidden in sculpt mode to improve performance and sculpt parts of the mesh that would otherwise be difficult to access
Motion tracker – there are a few smaller improvements, mostly related to 2D stabilization and a few smaller tools
