Version 1.3.0

In Development

Legend for changelogs

  • Major Feature : something big that you couldn’t do before.

  • Feature : something that you couldn’t do before.

  • Efficiency : an existing feature now may not require as much computation or memory.

  • Enhancement : a miscellaneous minor improvement.

  • Fix : something that previously didn’t work as documentated – or according to reasonable expectations – should now work.

  • API Change : you will need to change your code to have the same effect in the future; or a feature will be removed in the future.

Changed models

The following estimators and functions, when fit with the same data and parameters, may produce different models from the previous version. This often occurs due to changes in the modelling logic (bug fixes or enhancements), or in random sampling procedures.
