• Previously, GammaGammaFitter would have an infinite mean when its q parameter was less than 1. This was possible for some datasets. In 0.10.1, a new argument is added to GammaGammaFitter to constrain that q is greater than 1. This can be done with q_constraint=True in the call to GammaGammaFitter.fit. See issue #146. Thanks @vruvora
