@gr2m @nickfloyd The branch protection rules aren't valid for this branch. I feel like it's matching some generic v*.* matcher and including some workflows that haven't been here for a while

@wolfy1339 I've removed the invalid branch protection checks for the *.x branch protection rule. There are some other 1.x through 6.x rules as well, but hopefully those are far enough back in history they won't be relevant for us. Please let me know if you'd like more changes here!
