Thanks Roger, can we get this to the list please and make sure/test that
the message that the client gets back is very clear and perhaps even points
the user to the documentation to the min-juju-version feature so that it's
clear.

Nate, do we have notes on the feature in the devel docs or have the planned
location/path for those?

Thanks
