Microsoft Releases SQL Server 2008 SP2
From the download page:
Microsoft SQL Server 2008 Service Pack 2 (SP2) is now available for download. These packages may be used to upgrade any edition of SQL Server 2008. We remain committed to providing our customers with essential changes via Service packs. Service Pack 2 contains updates for SQL Server Utility, Data-Tier Application (DAC), as well as integration capability for Microsoft Reporting Services with the Microsoft SharePoint 2010 Technologies. Service Pack 2 introduces support for a maximum of 15,000 partitions in a database, and includes SQL Server 2008 SP1 Cumulative Update 1 to 8. While keeping product changes contained, we have made significant investments to ease deployment and management of Service Packs. Microsoft SQL Server 2008 Service Pack 1 is not a prerequisite for installing SQL Server 2008 Service Pack 2.
As a side note, if you are still on SQL Server 2005 SP2, Service Pack Support for SQL Server 2005 SP2 has ended as of January 12, 2010. More info here: http://blogs.msdn.com/b/sqlreleaseservices/archive/2009/10/08/end-of-service-pack-support-for-sql-server-2005-sp2-and-sql-server-2008-rtm.aspx
