Blender 2.47

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.
Modeling
• A range of 3D object types including polygon meshes, NURBS surfaces, bezier and B-spline curves, metaballs, vector fonts (TrueType, PostScript, OpenType)
• Smooth proxy style catmull-clark subdivision surfaces
• Boolean mesh functions
• Editing functions such as extrude, bevel, cut, spin, screw, warp, subdivide, noise, smooth Soft selection editing tools for organic modeling
• Python scripting access for custom tools
Animation
• Armature (skeleton) deformation with forward/inverse kinematics, auto skinning and interactive 3D paint for vertex weighting
• Non-linear animation mixer with automated walkcycles along paths
• Constraint system
• Vertex key framing for morphing, with controlling sliders
• Character animation pose editor
• Animatable lattice deformation
Realtime 3D/game creation
• Graphical editor for defining interactive behavior without programming
• Collision detection and dynamics simulation
Rendering
• Very fast inbuilt raytracer
• Integral support for the famous Yafray render engine
• Oversampling, motion blur, post-production effects, fields, non-square pixels
• Environment maps, halos, lens flares, fog
• Various surface shaders such as Lambert, Phong, Oren-nayar, Blinn, Toon
• Edge rendering for toon shading
• Export scripts available for external renderers such as Renderman (RIB), Povray, Virtualight
• UV texture editor with various mesh unwrap modes
Interface
• Flexible user configurable window layout
• Powerful object-oriented data system
Files
• Save all scene data in a single .blend file
