Time sure seems to fly by: OpenGL 4.0 turned five years old today. The sad part is that Mesa still doesn’t fully implement the GL 4.0 specification.
It was on this day back in 2010 that the Khronos Group released OpenGL 4.0 along with OpenGL 3.3. While Mesa ended up supporting GL 3.3 fairly quickly by the key drivers, OpenGL 4.0 remains to be supported.
