Changelog

Sourced from iminuit's changelog.

2.33.0 (September 16, 2026)

This release collects a large number of bug fixes in the Python API and the C++ bindings, several performance improvements, and new optional dependencies for easy setup.

Note: cost functions now receive plain float values instead of numpy.float64 ([#1136](https://github.com/scikit-hep/iminuit/issues/1136) <https://github.com/scikit-hep/iminuit/pull/1136>_).

New features

- Add optional dependency extras (`[#1189](https://github.com/scikit-hep/iminuit/issues/1189) <https://github.com/scikit-hep/iminuit/pull/1189>`_)
- Add ``llms.txt`` and Markdown page versions to the documentation (`[#1210](https://github.com/scikit-hep/iminuit/issues/1210) <https://github.com/scikit-hep/iminuit/pull/1210>`_)
