Unfortunately, no there isn't really - nothing that is specific to
individual APIs. I've mainly been focussing on getting a V3 specification
documentation up first (which I think is more important), but I do agree
that a transition document would be very useful as well.

This is a broad description of what was done:

https://etherpad.openstack.org/p/NovaV3APIHavana

which lists the types of changes which were made - eg CamelCase changes,
removal of proxying of services like glance through Nova etc. But I agree
we could do with something much better so its something we will do, I just
can't make any guarantees of when it will be available yet.
