@sliverc OK if I create the release (for practice;-)? I need to push a v2.8.0 tag against 88f7371 and then create a new release? And then something else to push to pypi.... Hmm, maybe you should do it.

@n2ygk
I usually create the release tag on github so I can link the changelog entry in the release notes and then upload it. On PyPi I don't have the permission to manage the project but only upload and so far I don't see you having upload rights. But I am happy to do the release.

I have released it now.
