[IMP-dev] IMP 2.1

It is time to start on the 2.1 release. There are currently two issues open in the tracker attached to that milestone - one regarding isd (#526) - and the MC mover/optimized behavior. I'd like to resolve the latter by adding checks so errors are thrown with most movers if they try to move non-optimized attributes, which should be a relatively quick change that I can do this afternoon.

Otherwise, is there anything else that someone thinks should be cleaned up before the release?
