Source distribution filename is incompatible with PEP 625

[martinburchell]

I got this email after running the release_new_version.py script to upload v0.20.6 to PyPI:

This email is notifying you of an upcoming deprecation that we have determined may affect you as a result of your recent upload to 'crate-anon'.

In the future, PyPI will require all newly uploaded source distribution filenames to comply with PEP 625 (https://peps.python.org/pep-0625/). Any source distributions already uploaded will remain in place as-is and do not need to be updated.

Specifically, your recent upload of 'crate-anon-0.20.6.tar.gz' is incompatible with PEP 625 because it does not contain the normalized project name 'crate_anon'.

In most cases, this can be resolved by upgrading the version of your build tooling to a later version that supports PEP 625 and produces compliant filenames.

If you have questions, you can email [email protected] to communicate with the PyPI administrators.
