Mesa 17.1 Officially Released with OpenGL 4.2 Support for Intel Ivy Bridge GPUs

Mesa 17.1 is a massive update that introduces numerous improvements for almost all supported open source graphics drivers, including Intel i965, RadeonSI, as well as RADV and ANV Vulkan drivers. Prominent changes include OpenGL 4.2 support for Intel Ivy Bridge GPUs in the Intel i965 OpenGL driver, which is now on par with its Android, macOS, and Windows counterparts, if even not better. The Radeon RADV Vulkan driver received various improvements to pass the Khronos Vulkan CTS (Conformance Test Suite), and shader on-disk cache was implemented to improve the startup and shader compilation times in many games.
