============== Release 0.14.3

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.

The Highlights

This release if a packaging and modernization release. It solves two key issues:

1. Corrects the build procedure for MacOS on both x86_64 and arm64
2. Improves compatibility with recent pandas releases

This release is NumPy 2.0 compatible. NumPy 2.0 is only available for Python 3.9+. This means that the minimum Python has been increased to 3.9 to match. NumPy 2 is only required to build statsmodels, and statsmodels will continue to run on NumPy 1.22.3+.

Note that when running using NumPy 2, all dependencies that use build against NumPy (e.g., Scipy and pandas) must be NumPy 2 compatible. You can continue to run against NumPy 1.22 - 1.26 along with other components of the scientific Python stack until all required dependencies have been updated.
