Hello:

does anyone happen to know, or have a detailed write-up, on the
differences between so-called "Glance v1" and "Glance v2"?

In particular do we still need Glance Registry in Havana, or
do we not? The best answer so far was to run the registry anyway,
"just in case", which does not feel entirely satisfactory.
Surely someone should know exactly what is going on in the API
and have a good idea what the implications are for the users
of Glance (API, CLI, and Nova (I include Horizon into API)).

Thanks,
-- Pete
