Visual Studio 2010 Service Pack 1 Beta which was released to MSDN subscribers on Dec 07 is now available to public. This beta comes with a go live license which means, you can start using this product for production related work, but be careful as it is still in beta,  so backup stuff before continuing to install SP1 .

Also remember that VS2010 SP1 Beta and the .NET Framework 4 KB2162169 Beta are licensed for use through June 30, 2011 at which point you’ll need to upgrade to the final release to continue using the product.

      IntelliTrace F5 for 64 bit and SharePoint project
      Performance Wizard for Silverlight

What's New in Visual Studio 2010 SP1 Beta

Visual Studio 2010 SP1 Beta includes the following improvements in diagnostics:

The debugger now supports IIS Express,  IntelliTrace now supports 64-bit debugging, IntelliTrace now supports Workflow and projects that use Web Parts controls. By default, IntelliTrace no longer saves IntelliTrace log files (.iTrace files) after you close Visual Studio. You can change the default behavior to enable IntelliTrace to save all log files, or you can manually save IntelliTrace log files, as described in the following procedures.

To change the default IntelliTrace log file behavior

I like updates in software because that means that your program is more reliable and more featurable. You can always rollback this changes or remove service pack if you want, but it is better to have up-to-date software all the time. The SP1 Beta comes with few bug fixes and also provides new features. Don't forget to shutting down or closing you current Visual Studio 2010 projects when installation begins.
