that's a good idea. Actually, I am missing this information on https://metrics.torproject.org/rs.html
as well - it appears as they still use an outdated location database there, but I don't know which one.

Yes, there is a scheme for the database _format_ (currently set to "1"), in case we need to change that
somewhere in the future. The versioning scheme for the database _contents_ is a simple timestamp, and
the output of "location version" is based on the database on your filesystem (not the most recent one
on the servers):

Yes, that is unfortunately kinda confusing... :-)

Thanks, and best regards,
