The latest OpenGL 3/4 documentation shows: Fortunately the OpenGL 4.5 Mesa support isn't in total shambles as some of the new GL 4.5 extensions were proposed by Brian Paul and others at VMware, which were part of the original Mesa team before the virtualization company acquired Tungsten Graphics. OpenGL 4.5 was an evolutionary update to the GL spec with the Khronos Group now focusing on developing a new graphics API to take on AMD's Mantle, Apple's Metal, and Microsoft's DirectX 12. Now that OpenGL 4.5 was released yesterday by the Khronos Group, while NVIDIA already has an OpenGL 4.5 driver, it will be a longtime before the open-source Mesa/Gallium3D drivers are able to claim OpenGL 4.5 compliance.
