Let us know here if you have any questions.

Pytest 8 is planned to be included in Fedora 41. And this bugzilla is a
heads up before we merge new pytest into rawhide. For more info see a Fedora Change
proposal https://fedoraproject.org/wiki/Changes/Pytest_8

We'd appreciate help from the people who know this package best,
but if you don't want to work on this now, let us know so we can try to work around it on our side.
