Cumulative Update 5 for the following Lync Products have been released

Microsoft has release CU5 for Lync 2010

Last week Microsoft quietly released CU5 for Lync 2010. The list of the various updates may be found below and the update includes a patch for mobility (if mobility is configured and deployed). I have installed the updates without any issue although the pool servers did require a reboot.

UPDATE: Lync Client and Server patches have been updated March 29th - the links below reflect the most current updates.
