It seems that this tag never got published to PyPI due to a failure in the integration tests.

The brotli package fails to build with the error:

I suspect there might be an outdated *.egg-info/entrypoints.txt or *.dist-info/entrypoints.txt somewhere in sys.path of the CI worker?

In my local test I can see that there is a /tmp/pytest-of-abravalheri/pytest-155/test_install_sdist_brotli_v_LA0/.venv/lib/python3.11/site-packages/setuptools-70.3.0.dist-info file in the generated virtual environment for some reason. Isn't the -I option in pip install supposed to prevent this from happening?

Other information relevant is that Brotli also uses the removed test_suite option.
