The Release Candidate (RC) for Parallels Workstation 2.2 for Windows and Linux is online and ready for download! 2.2 RC has a number of improvements, the most notable of which are stronger support for Intel Virtualization Technology and AMD Secure Virtual Machine Technology (both of which drive great performance and stability - see my recent blog post on the subject for more info), and the addition of Microsoft Windows Vista as a guest OS. You can check out the full list of new features here. The addition of Vista is a really great feature for our Windows and Linux users, since they now have the ability to test Vista and play with configurations without having to sacrifice an entire production machine. NOTE TO REGISTERED USERS: As with all updates, you won't need to reinstall your guest OSes, nor will you lose any saved data. You should, however, reinstall Parallels tools after updating your Parallels Workstation build. NOTE TO NEW USERS: You can download and install Parallels Workstation 2.2 on a "blank" system, and get a trial key to activate your copy. Get the Workstation 2.2 RC at the Parallels Workstation Download Center.
