(tagging @0mp, who is maintaining the FreeBSD port)

VERSION contains a version string that changes based on the state of the archive.

This means, right after v0.6.5 was released, the file contained:

d2f437a (HEAD -> master, tag: v0.6.5, develop)

later this changed to

d2f437a (tag: v0.6.5).

This results in hashes of artifacts changing, which means package builders relying on those being correct end up not being able to fetch the package - one would think that official artifacts stay the same, but it appears that this might actually not be the case (comparing contents of v0.6.6 and v0.6.5 sources on the release page lead to this assumption).

There a discussion about this here: python-versioneer/python-versioneer#217
