As of today Mesa now has full OpenGL 4.4 support (with 4.5 already done) for both AMD radeonsi and Intel (i965/gen8+). Mesa won't actually expose any higher than OpenGL 4.3 until Mesa (well, someone) pays up for the Conformance Tests.OpenGL 4.5 was also recently finished for AMD radeonsi, but it also needs the official Conformance Tests from Khronos.Going by this page on the official Khronos website it will cost quite a bit of money to get both done.Thanks for pointing it out in our IRC Lightkey!Once again, absolutely amazing progress.As always, you can track the progress on the MesaMatrix website. If you look at the bottom, Mesa is still missing a fair amount of extensions not related to any particular version of OpenGL, so still plenty of work to be done.
