============== Release 0.14.1

Release summary

statsmodels is using github to store the updated documentation. Two version are available:

  • Stable <https://www.statsmodels.org/>_, the latest release
  • Development <https://www.statsmodels.org/devel/>_, the latest build of the main branch

Warning

API stability is not guaranteed for new features, although even in this case changes will be made in a backwards compatible way if possible. The stability of a new feature depends on how much time it was already in statsmodels main and how much usage it has already seen. If there are specific known problems or limitations, then they are mentioned in the docstrings.
