Could you please be more specific? I'm unable to find such file in the git repo.

Oh, apparently we forgot to add it. That plugin you're removing requires this file and a .gitattributes change. Now, setuptools-scm implements this feature itself. So the same is necessary. Their readme has instructions. Also, I think there's a proper example in Cheroot.

I'll leave this to somebody else then...
