This new tool is accessible from the right click menu and allows for several new selection options.
To use the new selection tool right click on any face and select ‘Select Connected Faces‘.

You will then be presented with a pop-up menu which displays several selection options.

As of this writing the new selection tool is only available in Service Pack 2.0: Early Visibility but is anticipated to be available in the production release of Service Pack 2 for SolidWorks 2009.
