Full Changelog: 1.1.5...v1.1.6

What's Changed

Python

• Upgraded cmdstan version to 2.33.1, enabling Apple M2 support. @lucentcosmos @tcuongd
• Added a binary distribution for the macOS arm64 architecture (M1, M2 chips). @tcuongd
• Added argument scaling to the Prophet() instantiation. Allows minmax scaling on y instead of
  absmax scaling (dividing by the maximum value). scaling='absmax' by default, preserving the
  behaviour of previous versions. @yoziru
• Added argument holidays_mode to the Prophet() instantiation. Allows holidays regressors to have
  a different mode than seasonality regressors. holidays_mode takes the same value as seasonality_mode
  if not specified, preserving the behaviour of previous versions. @CoreyBryant-everi
• Added two methods to the Prophet object: preprocess() and calculate_initial_params(). These
  do not need to be called and will not change the model fitting process. Their purpose is to provide
  clarity on the pre-processing steps taken (y scaling, creating fourier series, regressor scaling,
  setting changepoints, etc.) before the data is passed to the stan model. @tcuongd
• Added argument extra_output_columns to cross_validation(). The user can specify additional columns
  from predict() to include in the final output alongside ds and yhat, for example extra_output_columns=['trend']. @dchiang00
• prophet's custom hdays module was deprecated last version and is now removed.

R

• Updated holidays data based on holidays v0.34

Full Changelog: v1.1.4...1.1.5

What's Changed

Python

• We now rely solely on the holidays package for country holidays. Credits to @arkid15r in #2379
  • This allows us to take full advantage of improvements to the holidays package, and removes reliance on unmaintained manual holidays entries in hdays.py. Importing from the prophet.hdays module has been deprecated and the module will be removed in the next release.
  • holidays v0.20 and beyond contains most / all previously missing holidays, so there should be very little differences in fitted models and predictions that currently make use of inbuilt country holidays.
  • Note that for countries like India and Pakistan, some Christian holidays are currently not included in the holidays package so will not be added automatically with .add_country_holidays(). These can be added manually instead, see examples here.
• Upgraded underlying cmdstan to v2.31.0, which fixes installation issues on Apple M1. Credits to @WardBrian in #2428
• Fixed a bug with Windows wheel builds caused by long path names. Credits to @WardBrian

R

• Updated holidays data based on holidays v0.25.

What's Changed

• Ensure compatibility with holidays 0.25.0 (#2431). Credits to @arkid15r
