Release Notes: This release contains a lot of additions and fixes. It includes a 120 page introductory tutorial, CG/GLSL support, much improved texture support (NPOT, 16 images/8 coords, SGIS_generate_mipmap, compression, and DDS files), user controllable material sorting, more robust binary file format, volume rendering, NURBS, general rendering optimizations, and much more.
Release Notes: The main focus of this release is restyling, restructuring, and documentation. A lot of the latter has been added, and the formerly separate starter guide is included. The main new feature is support for the ARB_vertex_program and ARB_fragment_program extensions.
Release Notes: The main additions are lots of ports (MS Visual Studio .NET, MS Visual Studio 6/Intel 6, gcc 3.x, HP-UX, and Mac OS X (partial)) and support for clusters. Other changes include support for multi-/cube- and volume textures, as well as particles and some stereo features.
