GLSL Hacker 0.5.0 (Windows / Mac OS X / Linux)
Recently at SIGGRAPH 2009, Khronos and the ARB announced OpenGL 3.2 and GLSL 1.50. We have continued to increment 3D graphics capability on a 6 month schedule. OpenGL 3.2 adds a few larger pieces of functionality along with many smaller tweaks, while still being compatible with most modern installed GPUs. If you have a 1 or 2 year old GPU, chances are a driver update will bring you OpenGL 3.2.
