Hello Everyone, Hacking 6.0.0 is available to use now which includes flake8 5.0 changes. There are no other changes than bumping flake8 version to 5.0.1, you can refer to the changes done in flake8 5.0.0 (or 5.0.1) directly in flake8 release notes - https://flake8.pycqa.org/en/latest/release-notes/5.0.0.html Note: hacking is pinned in test-requirements.txt (for almost all the repo), do not forget to bump the version there while moving your code to new hacking. -gmann
