关于这个版本

继续Blender 2.4x系列让我们周期性得发布错误修订版本，新功能请关注Blender 2.50（2.50，不是5），允许开发者来实现根本的改变需要一个很长的开发周期。

一个完整的错误修复列表已经可用了，如果你想阅读所有细节。或者继续阅读一个一个快速的“简短版本”：

• SSS now works with panorama render.
• Removed artifacts with negative lights when using SSS
• Disabled SSS for preview rendering, so it didn't slow down other preview render at all.
• Fixed error in "Transform Constraint" with planar constraints when the plane was perpendicular to the viewport.
• Fixed the vector blur error in "Ztransp" that produce black lines (on edges) appeared, which didn't get blurred away.
• Fixed an error in the Particle System that cause bad results for command line renders, especially when rendering first frame of animation.
• Fixed Verse crashing in 64 bits Linux.
• Math node now has reflective behavior.

• Multires meshes with UV's and vertex colors would crash in many cases.
• Importing 3DS files with lamps failed.
• FBX Exporter updated, includes fixes for better compatibility with other applications and support for exporting animation with armature deformed meshes and objects.
• Collada support updated for better armature support.
• Bundled python modules were not included in 2.44 by accident, making some scripts fail in 2.44 that worked in 2.43 (Windows Only, when Python was not installed)

• Fixed bug in the shadow calculation that cause errors where specularity would ignore shadows.
• Changes to the insert keyframes method for determining when to replace existing keyframes with new ones. Now, it shouldn't create so many keyframes stacked on top of each other.
• Blender would crash if boolean operations were done on objects wich resulted in an empty mesh. This was due to accessing invalid memory.
• Remove the options "make local" in the Outliner. It didnt work properly and produced errors in the linked data.
• Edgesplit crashes are fixed, the problem was that "bridge" vertices (which connect two or more faces that don't share edges) were not being included in the maximum final vertex count calculation (used for memory allocation, hence the crashes).
• Fixed Multires Editmode memory leak. Typo in Multires Editmode integration meant that far too much memory was getting allocated for a pointer array (more than 10 times as much).
