Looks good to me, but tests are currently failing. I've pointed out where I think the problem is.

This may be the main cause of test errors. The local variable beta_factor is deleted here, but I don't see self.beta_factor used anywhere.

Thank you! I think this is ready to be merged. Can you just update the releasehistory.rst in docs/ before?
