There were some updates released yesterday for Microsoft OCS 2007 R2.
I haven’t had a chance to look at them in detail, but they all look mostly related to the Group Chat functionality:
- Group Chat Server (KB 2728998): http://support.microsoft.com/kb/2728998
- Group Chat Administration Tool (KB 2728997): http://support.microsoft.com/kb/2728997
- Group Chat Client (KB 2735021): http://support.microsoft.com/kb/2735021
These updates bring the build number up to 3.5.6907.258.
The noteworthy hotfix that is addressed is the delay when adding a member to a Group Chat room.
