Release Notes

pyo3/pyo3 (pyo3)

### [`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 [@​minrk](https://redirect.github.com/minrk) for the report and [@​davidhewitt](https://redirect.github.com/davidhewitt) for the fix!
