 <sup>¹ PyPy is only supported for manylinux wheels.</sup><br>
 <sup>² Windows arm64 support is experimental.</sup><br>
 <sup>³ Alpine 3.14 and very briefly 3.15's default python3 [was not able to load](https://github.com/pypa/cibuildwheel/issues/934) musllinux wheels. This has been fixed; please upgrade the python package if using Alpine from before the fix.</sup><br>
+<sup>⁴ CPython 3.11 is available using the [CIBW_PRERELEASE_PYTHONS](https://cibuildwheel.readthedocs.io/en/stable/options/#prerelease-pythons) option.</sup><br>
 
 - Builds manylinux, musllinux, macOS 10.9+, and Windows wheels for CPython and PyPy
 - Works on GitHub Actions, Azure Pipelines, Travis CI, AppVeyor, CircleCI, and GitLab CI
