uv ships pre-built wheels to [PyPI](https://pypi.org/project/uv/) for its Tier 1 and Tier 2
platforms. However, while Tier 2 platforms are continuously built, they are not continuously tested
or developed against, and so stability may vary in practice.

Beyond the Tier 1 and Tier 2 platforms, uv is known to build on i686 Windows, and known _not_ to
build on aarch64 Windows, but does not consider either platform to be supported at this time. The
minimum supported Windows versions are Windows 10 and Windows Server 2016, following

Did you mean to say "This isn't as well known as ..."?

I'm not sure if we should talk about this here though. It seems out of place? I think it makes more sense in the Python version discussion?

Like maybe in https://docs.astral.sh/uv/concepts/python-versions/ ? I'm not sure where would be best. It feels out of place here to talk about Python package support though.

as x86_64 Python with x86_64 packages can also be used. The minimum supported Windows versions are
Windows 10 and Windows Server 2016, following
