What's Changed

Python

• Minimum required version of Python is now 3.7
• Removed dependency on pystan==2.19.1.1, which is no longer maintained. cmdstanpy is now the sole stan backend. Credits to @WardBrian @akosfurton @malmashhadani-88
• Python binaries built for MacOS, Linux, and Windows for Python 3.7-3.10, so end users no longer need to compile the Prophet model from source on their machine.
  • Binaries are built using Github Actions. Credits to @abitrolly for simplifying the workflow.

Other improvements

• Use normal-id-glm distribution for Stan model to improve MCMC sampling speed (the model itself is still identical). Credits to @andrjohns
• Improved execution time of rolling_mean_by_h function used to calculate cross validation performance metrics. Credits to @RaymondMcT
• Update holidays data based on holidays package version 0.13.
