Microsoft released new cumulative updates for SQL Server.
SQL Server 2008 R2 Service Pack 1 Cumulative Update # 10
SQL Server 2008 R2 Service Pack 2 Cumulative Update # 4
My usual disclaimer: these updates are NOT for SQL Server 2008. Only apply to systems where @@VERSION returns 10.50.xxxx, where xxxx is >= 2500. If xxxx < 2500, you need to start thinking about getting off the RTM branch.
