On February 17, 2014, Microsoft released SQL Server 2008 R2 SP2 CU11, which is Build 10.50.4302. This cumulative update has twelve hotfixes in the public fix list.
If you are running SQL Server 2008 R2, the only supported Service Pack level is SP2. Both SP1 and RTM have been retired. This means that if your build number is less than 10.50.4000, you are on an unsupported Service Pack and this cumulative update will not work for you.
I think it is a little ridiculous that we don’t have a SQL Server 2008 SP3 yet. Based on the recent public hints from Microsoft, there might not be a SQL Server 2008 R2 SP3, before this version of the product goes out on Mainstream Support on July 8, 2014.
If you have any thoughts about this, I ask you to take a minute and vote for my Connect item about Service Packs, and also leave a comment. Thanks!
