The new specification has been three years in the making – work actually started before the release of our last major release, OpenGL ES 1.1.

OpenGL ES 2.0 brings shader-based rendering to cell phones, set-top boxes, and other embedded platforms. It’s here at last! At the Game Developers Conference in March, the OpenGL ES Working Group announced the release of OpenGL ES 2.0, the newest version of OpenGL for mobile devices.
