Exchange 2013 CU1 Released!

Following the release of Exchange 2010 SP3 in February, the Exchange Team have announced the release of Exchange Server 2013 Cumulative Update 1 (CU1). CU1 does include some new features, including *some* access Public Folder content through Outlook Web App but I think it is fair to say that legacy coexistence is the reason everyone has been waiting for CU1. CU1 is the minimum version of Exchange 2013 required for on-premises coexistence with supported legacy Exchange Server versions, but, before you steam ahead and install it I think it is important to understand all the caveats of coexistence so be sure to check out the Planning and Deployment documentation. Scott Schnoll put together a great post about the high availability changes in Exchange 2013 CU1 which is also worth reading.
