###
[`v0.22.6`](https://redirect.github.com/PyO3/pyo3/releases/tag/v0.22.6):
PyO3 0.22.6

[Compare
Source](https://redirect.github.com/pyo3/pyo3/compare/v0.22.5...v0.22.6)

This release corrects the check for free-threaded Python introduced in
PyO3 0.22.2 to prevent users accidentally installing PyO3 packages on
Python 3.13t; PyO3 0.22 does not support free-threaded Python. (Stay
tuned for the 0.23 release coming very soon!)

Thanks [@&#8203;minrk](https://redirect.github.com/minrk) for the report
and [@&#8203;davidhewitt](https://redirect.github.com/davidhewitt) for
the fix!
