* Since all System Center 2012 products are on the same release cycle the UR number increases with each release whether each product has a release or not.
Latest available Update Rollup for System Center 2012 Products: 6 This Update Rollup 6 was only for System Center Virtual Machine Manager 2012. Operations Manager did not have any patches for UR6 for server/console/agent/gateway. The only OpsMgr UR6 content are MPs and agents (MPBs) for UNIX/Linux.
** The updated agents/MPs for SP1 also work for 2012 (with the exception of Microsoft.Unix.Library)
