This fixes #163 because on release these files weren't included and I was able to replicate the reporters findings only when using a clean vm to test with.

@kognate can you revert the bump version commit ?

I think the way we do releases is using bumpversion. So we first do all the code changes and then we do bumpversion patch

@german I reverted it.
