Looks good, but I noticed you haven't addressed CustomPythonBuild in setup.py.

Good catch!

This will generate an incorrect base_version including the git hash

If the purpose of this change is to make plugin version parsing easier, should there be a deprecation cycle to send the __version_info__ instead of __version__ to plugins plugin function?

I guess this is the next step 🙂

We don't require a deprecation period for plugin API changes.

base_version shouldn't include git hash, as KotlinIsland points out. There are also merge conflicts.

While we don't require a deprecation period for plugin API changes, we need to be careful about breaking things here, since allowing plugins to branch on version is what enables us to play fast and loose with breaking plugins.
