After far too long, and way more changes than originally intended, PyOpenGL 3.1.0 final is now out. The big changes are:
This release should be largely compatible with anything that worked with 3.0.2 as long as that code didn't poke around in the internals of PyOpenGL too much. The structure of the package has changed significantly in order to allow for loading e.g. GLES or GL without loading the other APIs, and to make the code less GL-arrogant (i.e. to make ES a more-or-less-equal api).
pip install PyOpenGL PyOpenGL_accelerate
