Parallels must have been missing their beta days, as they have already announced a new beta version of their Desktop software at WWDC today that brings quite a few much-requests updates. Parallels Desktop, in case you haven't been following the Mac web the last few months, is virtualization software which enables users to run Windows and other OSes inside of Mac OS X on Intel Macs.
At the top of the list of updates is much-improved USB performance and broader device support, including Windows Mobile 5 devices. Fleshing out the list is "substantially" improved Mac OS X performance while running a virtual machine (which is a different OS, like Windows. We've explained virtual machines before in our Parallels Desktop How To), improved graphic performance, complete keyboard support including the Eject key and shift key mapping for non-English layouts, Unicode path support, improved shared folder performance and, of course, minor bug fixes.
This is, or will be, a free update for paid users once it goes official. For now, users can download the beta the Parallels Desktop update page.
