Microsoft has released SQL Server 2008 SP1 Cumulative Update 9 (CU9). The KB Article for the CU is located here. This is Build 2789, and it contains 34 fixes, that are pretty well scattered over the Engine, SSAS, SSRS and Full-Text Search.

Don’t forget, Microsoft has “retired” the RTM branch of SQL Server 2008, which means that there will be no more CUs for that branch, and that they will only provide limited troubleshooting support if you call CSS with an issue when you are still on the RTM branch. You really need to get on the SP1 branch if you have not done so already.
