Today the Exchange Team announced postponing the release of Exchange 2013 Cumulative Update 1 for a few more days. Originally, CU1 was scheduled for Q1 2013, but the date has been set now at April 2nd, 2013.
While it may sound disappointing when you’re waiting for Exchange 2013 RTM CU1, it makes sense to postpone it a bit. As the team indicated,the time is used to add functionality required for coexistence scenarios with Exchange Server 2010 which otherwise had to be put in an update for Exchange 2010 Client Access servers. I expect people to be less happy as Exchange 2010 Service Pack 3 was heralded as the Exchange 2010 product level for coexistence support with Exchange 2013 (running CU1).
Also, looking at time frames involved with testing and accepting updates in production environments, I personally applaud this decision as putting that code in Exchange 2013 at the cost of a few days may in the end be faster than adding that code to Exchange Server 2010, requiring customers to initiate test an acceptance tracks for production updates.
So, until further notice we’ll have to wait just a few more additional days to see what Cumulative Update 1 will bring us.
Is there a list of changes anywhere for 2013, or is it purely for co-existence?
In time, all will be revealed. I suggest monitoring the various blogs, feeds, Twitter, etc.
