I'm confident that my changes don't break compatibility with these Python versions, though I haven't tested them to 
be sure.

I have access to the upstream repo and the testing.pypi.org entry and can make changes there.
Bernhard would you mind to upload the prerelease version that is on the testing registry? This would simplify the 
work of John to document the installation process of gpg until a new version of the bindings are tagged.
If a new version is tagged I will build and upload it to the testing registry.
