At Siggraph 2014, the Khronos Group has announced both OpenGL 4.5 and, more excitingly, the Next Generation OpenGL Initiative. OpenGL 4.5, except for some new Direct3D 11 emulation features for easier porting, is your fairly standard annual OpenGL update. Next Generation OpenGL (OpenGL NG), however, is a complete rebuild of the OpenGL API. The idea, much like AMD's Mantle and DirectX 12, is to build an entirely new version of OpenGL that removes a lot of the abstraction, significantly reducing the overhead and inefficiencies when working at a low level with the bare metal GPU hardware.
