Version 4.2 of the OpenGL graphics programming interface is complete, and progress is being made on WebGL and OpenCL. At three "Birds of a Feather" meetings on OpenGL, WebGL and OpenCL, representatives of AMD, NVIDIA, Google and Opera talked about the state of development and future plans. The main changes concern the official release of version 4.2 of the OpenGL graphics programming interface. Now, OpenGL shaders ("programs") can have side effects instead of just generating vertices and colouring pixels.
