Great to see that there is attention on the FIM 2010 product. A small hotfix has been released a few days ago. However small it may be, it definitely has some good things, namely the support for password history (see KB2443871) and of course a few other bugfixes.
I haven't had time to check out whether the bug with regards to casing in flows have been fixed and is included. There is nothing in the release notes stating this, but one could hope. I'm keeping my fingers crossed for this for my testing with the next days.
You can find the hotfix here.
