• Added general QCD running coupling up to 4 loops.
• Sped up and stabilized fitter, especially when there are nontrivial covariances.
• Added Legacy module holding deprecated code.
• Sped up jackknife; added remove-1 jackknife; deprecated old version.
• Added wrapper for Scipy IVPs.
• Added Pearson correlation coefficient.
• Added statistical physics simulation framework. Tested for 2d Ising model, which is added as an example.
• Found bug in dense observable code. Still trying to fix this, but for now, it has been removed from tests, and a warning is flashed not to use it.
• Added statistical physics reweighting.
• Added several information criteria to fitter.
• Added model averaging code using Bayesian Akaike information criterion.
• Added empirical CDF and Kolmogorov-Smirnov test wrappers.
• Added confidence ellipse method.
• Various other bug fixes and improvements.
