Thanks to a lot of hard work by Mike assisted by Dave Airlie and Adam Jackson, both of RedHat, Zink is now able to expose the OpenGL 4.6 (Core Profile) feature set, given enough Vulkan features! Similar to the OpenGL 4.6 support, we're now able to expose the OpenGL ES 3.1 feature set. But we have patches in the works to bring this up to OpenGL 4.5, and OpenGL 4.6 probably won't be far off when that lands.
