Finally after a long waiting period, Microsoft release SQL Server 2008 Service Pack 4, Same is now available for download at the Microsoft Support site. SQL Server 2008 Service Pack 4 contains all the hotfixes released since the initial release of SQL Server 2008 RTM.
I suggest to test SQL Server 2008 Service Pack 4 in test environment & then move to Production after satisfactory results.
Cumulative Updates for SQL Server 2008 SP4 will not be released.
