## The problem
Oso 0.22.1 on PyPI had no wheels for Python 3.10 and no source distribution either, so pip install oso failed on the latest stable Python. cibuildwheel supported 3.10, but the release artifacts had not been built for it. The reporter pointed at cibuildwheel 2.1.3 as the tooling that could produce the missing wheels.
## The fix
The maintainer built and uploaded the Python 3.10 wheels to PyPI for oso 0.22.1, so a plain pip install works again. If you hit this on an old pinned version, upgrade to the re-released 0.22.1 (or newer); the reporter confirmed it installs fine after the wheels were published. The maintainer also attached the wheel archive to the issue for anyone who could not wait for the PyPI upload.
