On July 15, Microsoft released SQL Server 2008 Service Pack 3 Cumulative Update 12, which is Build 10.0.5844. I count six fixes in the public fix list.
If you are still running SQL Server 2008 (and I know many people are), you should be aware that only Service Pack 3 is still a supported Service Pack. You should also keep in mind that SQL Server 2008 will fall out of Mainstream Support from Microsoft on July 8, 2014, which is not that far away.
I am curious about whether there will be a SQL Server 2008 Service Pack 4 or not? SQL Server 2008 Service Pack 3 was released back on October 6, 2011, which is quite some time ago.
