@kddejong will you release the fix to PyPI anytime soon? :) The reason is there are several GitHub-actions (e.g. https://github.com/ScottBrenner/cfn-lint-action) which pull cfn-python-lint from the PyPI, and they seem to be broken at the moment.

P.S. the policies.js file has been changed again to the latest revision, but I guess this is covered now, so just for your information.

Yea let me get the release out today.
