Intel's Mesa Driver Now Has OpenGL 4.0 Support

Intel's Mesa driver is now at OpenGL 4.0 compliance with the landing of ARB_gpu_shader_fp64.

The FP64 OpenGL extension was made it to Git over the night and that was the last extension remaining prior to exposing OpenGL 4.0. Currently this OpenGL 4.0 support is just for Intel Broadwell hardware and newer.

Igalia developers had been working on the ARB_gpu_shader_fp64 support the past few months. FP64 support for pre-Broadwell hardware isn't expected until later this year. Igalia developers are also finishing up the related ARB_vertex_attrib_64bit extension, which should be done in the next few days, and that's needed for OpenGL 4.1 compliance. All of the GL 4.2 changes are also done so by the end of the week we should be seeing OpenGL 4.2 support for Broadwell and newer with the Intel driver.
