Comment 16 for bug 1593828

I got some good review feedback from Gustavo on the mgo PR - I've addressed his comments (I think) and I'll ask him to make another pass, and hopefully merge it into v2-unstable and v2. Once that's merged I can start updating the mgo dependencies for packages in our tree (and also any packages that depend on these packages):

gopkg.in/juju/jujusvg.v1
gopkg.in/juju/charmstore.v5-unstable
gopkg.in/juju/charm.v6-unstable
gopkg.in/juju/charmrepo.v2-unstable
gopkg.in/macaroon-bakery.v1

github.com/juju/idmclient
