I'm pleased to announce the release of the first Service Pack of SQL Server 2008 is now available. Service Pack 1 (SP1) focuses on essential updates only, primarily roll-ups of cumulative updates 1 to 3 and fixes to issues reported through the SQL Server community. SP1 eases deployment and management of Service Packs by introducing Slipstream, Service Pack Uninstall, and Report Builder 2.0 Click Once capability.
You can download SQL Server 2008 SP1 from the Microsoft Download Center.
