While illustrating how Fedora integrated its multiple Python versions into its recommended dependency for tox, I noticed that python3.11 didn't get added after the system Python package was bumped up to Python 3.12: $ sudo dnf repoquery --recommends tox 2>/dev/null pypy2-devel pypy3-devel python2-devel python2.7 python3-devel python3.10 python3.6 python3.7 python3.8 python3.9 Reproducible: Always Steps to Reproduce: Query the recommended requirements for the tox package Actual Results: python3.11 is not listed Expected Results: python3.11 should be listed Adding the extra recommends to the tox package for the previous major version should be noted as a task in the Python major feature bump proposals like https://fedoraproject.org/wiki/Changes/Python3.12 This missing recommendation hasn't been noticeable on system upgrades (presumably due to the requires/recommends cycle between python3.x and python3.x-libs keeping the former major version installed if it was previously installed)
Never mind, the problem was in my queries, not the RPM metadata; I didn't check the reverse supplements declarations (as per https://lists.fedoraproject.org/archives/list/python-devel@lists.fedoraproject.org/thread/NVVUXSVSPFQOWIGBE2JNI67HEO7R63ZQ/) Sorry for the noise.
> While illustrating how Fedora integrated its multiple Python versions into its recommended dependency for tox, I noticed that python3.11 didn't get added after the system Python package was bumped up to Python 3.12. This is still a problem. But it isn't caused by missing Recommends, but generally by the way weak dependencies are handled by dnf :(
