We just released Irrlicht 1.4. It includes all features from the beta version such as

• A rewritten unified skeletal animation system with some more sophisticated long awaited features such as manual joint animation.
• Irrlicht’s own file format: .irrmesh, for static meshes.
• Mesh writing support: Write collada, .stl and .irrmesh files. Irrlicht now can also read .stl files and be used to convert any file it can read into these file formats.
• Enhanced Particle System reintegrated from the irrSpintz fork
• Improved GUI: Keyboard control support (tab, shift etc), SpinBox,
• PointSprite support
• Improved collada, .obj, .my3d and loaders
• Tons of bug fixes and other feature enhancements

Happy downloading!
