PyOpenGL 3.0.1 is pretty much finished AFAICS. The biggest visible change is support for the OpenGL_accelerate module (written in Cython) which provides a noticeable speedup for my applications. However, the fact that the code is C (once generated) means that bugs are going to be introduced (including possible segfaults).
There are also a number of bug-fixes in the code since the 3.0.0 release. So, if you'd like to help out, branch the current head, compile the OpenGL_accelerate module and test (or test without the accelerate module, if you'd like to help with testing that version as well). Particularly need testing by people with weird and exotic platforms, like Win32 or OSX. 32-bit Linux could also use testing.
