Microsoft made a Community Technology Preview (CTP) of the SQL Server 2008 SP1 available to the testers yesterday. There is not much to say about it, expect that it has been made available for general testing purposes only, so not deploy the CTP software in a production environment.

The final release of the Service Pack 1 is expected to be in early April 2009.

The final version of the Service Pack 1 for SQL Server 2008 has been released on the 7th April 2009. Please read this post for more information and download links.
