We are very pleased to announce the first public CTP (Community Technology Preview) of Microsoft SQL Server 2008 R2 for MSDN and TechNet subscribers.  Availability for non-subscribers is planned for August 12th.

This is the first public CTP so it is not feature complete but it sure has enough exciting content for you to explore.
Some of the features that are in this build are:
- Application & Multi-Server Management
- Report Builder 3.0
- Scale Up with support for up to 256 logical processors

The Data Platform Insiders blog has a detailed post with all information regarding this CTP.

Please feel free to download and start using the CTP and help us deliver yet another great product by providing your much appreciated feedback.
