Comment 11 for bug 1384555

Due to this bug Neutron will only work with version <= 5.5 of mysql/mariadb, e.g. older versions. Downgrading to 5.5 isn't a solution, it's a workaround! It also means there is no database upgrade path for OpenStack, and this version limitation isn't mentioned anywhere in the documentation.

I'd say that's a pretty big deal that somebody should look at! If not a Neutron core developer, then somebody that works on SQLAlchemy. If nobody is willing to address the actual technical issue then at least the version limitation should be added to the documentation.

Can't force you to work on this, just saying that I think ignoring this would be a mistake.
