INTEL --
The latest patches from Igalia have been published for finishing up the ARB_gpu_shader_fp64 implementation within Intel's Mesa driver, which would bring it into supporting OpenGL 4.2 (thanks to the other extensions already being completed) for the latest generations of Intel hardware.

The developers are working to get Intel at OpenGL 4.2 compliance for the next Mesa release due out next month (June). This OpenGL 4.2 compliance and these FP64 patches are just for Broadwell and newer; it wouldn't be until later that pre-Broadwell Intel hardware gets OpenGL 4.x support by the open-source Mesa driver.

These 30 latest patches for review can be found via the Mesa-dev list but are hopefully just a few days away from landing in Mesa Git, which should happen before the 11.3/12.0 branching.
