As we announced previously, StresStimulus PRO v1. 0 will be available for download and purchase on Monday 8/1. Feature-wise it is very similar to the RC, but will have several great enhancements.

The RC is available for download. It replaces the soon expiring previous versions. This is expected to be the last version before the v1. 0 launch, currently scheduled for Aug 1, 2011. Licensing / pricing for the retail version is available here.
