I don't see a wheel for Windows cp313t in the list of release files https://pypi.org/project/pandas/2.2.3/#files.
I see a job is running that should produce the wheel: https://github.com/pandas-dev/pandas/actions/runs/14920899116/job/41915964757
Perhaps the wheel was accidentally omitted in the release process?

Thanks for the issue, but our 3.13t wheels will be released in pandas 3.0. Our nightly wheels have 3.13t wheels though https://anaconda.org/scientific-python-nightly-wheels/pandas/files. Closing as we won't be supporting free threading in pandas 2.2.3

Understood, thanks!
