FYI if you use Data Protection Manager (DPM), the predictably regular rollup for June is up, http://support.microsoft.com/kb/970867. This gets you to 2.0.8844. The bits are available without a call to PSS if you haven’t got Premier portal access as well.
Conveniently this one doesn’t seem to require a restart of every protected host following the agent update. The console and the KB concur on this fact too. One quirk I did observe is that it would appear that DPM doesn’t attempt to suspend backups while rolling out agent updates because 2 of my 27 storage groups failed with some random HRESULT and a complaint about the state of the DPM agent.
