python-igraph 0.9.5

Fixed

• plot(g, ..., mark_groups=True) now works with the Matplotlib plotting backend.

• set_random_number_generator(None) now correctly switches back to igraph's own random number generator instead of the default one that hooks into the random module of Python.

• Improved performance in cases when igraph has to call back to Python's random module to generate random numbers. One example is Graph.Degree_Sequence(method="vl"), whose performance suffered a more than 30x slowdown on 32-bit platforms before, compared to the native C implementation. Now the gap is smaller. Note that if you need performance and do not care about seeding the random number generator from Python, you can now use set_random_number_generator(None) to switch back to igraph's own RNG that does not need a roundtrip to Python.
