Continuing Blender 2.4x series, Blender 2.47 is a bugfix release to stabilize the "Bunny Release", serious effort has been put in tracking bugs and fixing them.
A complete list of bugfixes is available if you want to read all the nasty details. Or keep on reading for a quick "short" version:
- New tools and improvement have been made to the Snapping tools.
- Better Game Engine logic.
- Revised alpha blending in the Game Engine.
- PyConstraints and PyDrivers are not executed unless scriptlinks are enabled (for improved security)
- Fixed an incorrect transformation for particle group visualization.
- Fixed negative value in the Gamma node with negative input.
- Tangent shading (which only affects specular) made bump mapping not work for diffuse.
- Fixed Mesh Deform Modifier not working on extruded curves.
- Fixed crash converting old particle system from a linked file.
- Object instancing didn't restore matrices correct for Environment Map, this could give object rendering in the wrong position.
- Compositor nodes with use nodes disabled didn't properly redraw the node window on changes.
