----------------------------------------------------------------
Eli, currently the functionality is almost complete (renames have been pain).
We are doing reviews of areas that need more unit tests and doing long running
tests and testing at scale on a cluster. First goal is to get this to trunk and
we hope we can get this done by the end of this month. Hopefully by that time
we are done with our tests and can get it into 2.0.5 beta.
