Ok, ok, so this is cut and pasted directly out of their press release, which can be read in it’s entirety here:
Now you can run Windows on your Mac Pro, without having to reboot the compuer. Update Release Candidate also adds Experimental Support for Windows Vista Beta
Parallels announced today that it is making available the Update Release Candidate (RC) for Parallels Desktop for Mac, the first solution that enables users to run Windows and other operating systems at the same time as OS X on any Intel-powered Mac, without re-booting.
The update RC, which is free for all Parallels Desktop users, adds support the recently released quad-processor Mac Pro towers outfitted with up to 3.5GB of RAM. With the addition of support for Mac Pro towers, Parallels Desktop for Mac is now compatible with all Intel-powered Apple computers, which in addition to the Mac Pro includes the MacBook, MacBook Pro, iMac, and Mac Mini.
The update RC also offers full compatibility with the developer builds of Mac OS X 10.5, code-named “Leopard.” Leopard, which was previewed in Steve Jobs’ keynote address at the 2006 Apple Worldwide Developer Forum, is expected to be ship in Spring 2007.
“By adding support for Mac Pro towers and OS X ‘Leopard’, we’ve shown once again that Parallels Desktop is not only a great productivity tool for any Intel-Mac user, but also for Mac software developers who need to work with Apple’s next-generation OS.” said Benjamin Rudolph, Marketing Manager, Parallels. “Now, anyone using a Mac Pro, Mac Mini, MacBook, MacBook Pro or iMac can run any version of Windows alongside any Intel-compatible version of OS X, including 10.4 ‘Tiger’ or the upcoming 10.5 ‘Leopard’.”
In addition, the Parallels Desktop for Mac update release candidate includes experimental guest OS support for the beta builds of Windows Vista, the next-generation of Microsoft’s Windows operating system. Vista is due to be generally available in 2007.
