Flake8 5.x breaks flake8-logging-format:
plugin code for `flake8-logging-format[logging-format]` does not match ^[A-Z]{1,3}[0-9]{0,3}$
Right now we're working around that by pinning tox.ini to use flake8 4. There's a merged but not-yet-unreleased upstream fix: https://github.com/globality-corp/flake8-logging-format/pull/33.
