Vulkan, the next generation OpenGL to compete with Apple’s Metal

While Vulkan 1.0 is out for high performance graphics, OpenGL isn't being abandoned by the Khronos Group but the working group will remain and evolve. Vulkan won't be needed by all game/application developers depending upon how much you care about performance, if you need legacy driver / graphics card support, are looking for an API that's easier to target, your workload can't be parallelized, etc.

There's also been talk of adding SPIR-V support to OpenGL and making other improvements on that front. The Khronos Group isn't announcing any new OpenGL specifications/updates officially today, but stay tuned for later this year.
