Released: Exchange Server 2013 RTM Cumulative Update 1

If you have the RTM version of Exchange 2013 and you are upgrading to CU1 you may run into an issue with the UCMA 4.0 not being the correct version.  Originally the UCMA 4.0 version was a 'Preview' version (5.0.8132.0) which was downloaded from http://download.microsoft.com/download/8/5/4/8540E09D-3435-4182-B855-C8BB85E1EEE0/UcmaRuntimeSetup.exe.  Now the CU1 requirements looks like it has the same UCMA 4.0 component listed as a requirement, but the download is located at http://download.microsoft.com/download/2/C/4/2C47A5C1-A1F3-4843-B9FE-84C0032C61EC/UcmaRuntimeSetup.exe.  The version of this UCMA is now 5.0.8308.0.  It would be nice if there was some reference on this post or the Release Notes that this is something to be aware of.  Thanks.
