Phoronix: Mesa Now Supports Another OpenGL 4.5 Extension
While Mesa is still racing towards OpenGL 4.0 compliance, another OpenGL 4.5 extension can now be crossed off the Mesa TODO list...
Now supported by i965 as well
I expect a jump to 4.2 first, then Intel will finish up compute shaders which will give them 4.3 and GLES 3.1. Then probably full GL4.5 soon after that. By then, hopefully the new GL 5 or whatever they call it will be to the point where Mesa can at least start working towards it.
