Some great news (I know it's not the latest) for every 3D gamer and developer. Mesa supports OpenGL 2.0.
Mesa is know to be the free cross-platform implementation of OpenGL, partitially lags the latest OpenGL version, now advanced features from OpenGL 1.5 to 2.0. One of these improvements is the OpenGL Shading Language GLSL, which directly executes shader by the GPU.
Last september OpenGL released version 2.1, and the next extension of OpenGL, Longs Peak and Mount Evans, are planned this year. Since Mesa involves some full time programmers, the hope to support new features early improves. At least not to wait again some years; this one needed time since 2003.
