OpenGL 2.1 increases power and flexibility of OpenGL’s programmable graphics pipeline;

The new OpenGL 2.1 specification adds backwards compatible enhancements to OpenGL’s advanced programmable pipeline including: Pixel Buffer Objects for fast texture and pixel copies between frame buffer and buffer objects in GPU memory; texture images specified in standard sRGB color space for enhanced application color management flexibility; and numerous additions to increase the flexibility of shader programming including non-square matrix support, support for arrays as first-class objects, a fragment position query in shaders using Point Sprites and an invariant attribute for variables to enhance shader code reliability.

Also announced, the Graphic Remedy Academic program will offer a free one year license to its gDEBugger OpenGL debugger and profiler tool to OpenGL developers in academia.
