Some of the changes are:-
As usual if you're a current Parallels owner get the new Beta2 HERE from the Parallels website.
NEW! USB 2.0 support - “Plug and play” popular USB devices like external hard drives, printers, and scanners, and use them at full native speed.
NEW! Full-feature virtual CD/DVD drive - Burn CDs and DVDs directly in virtual machines, and play any copy-protected CD or DVD just like you would on a real PC
NEW! Better Boot Camp support - Using your Boot Camp partition in Parallels Desktop is now easier than ever. Beta2’s Boot Camp support includes:
Full support for FAT32 and NTFS partitions
Easy offline configuration. Simply tell Parallels Desktop that you want to create a virtual machine from a Boot Camp Partition and click start. No complicated set up required!
No need to re-activate Windows each time you switch between Boot Camp and Parallels. Activate Windows only once inside Parallels and work in both environments
IMPORTANT! It is not possible to suspend a Virtual Machine that is connected to Boot Camp as it could result in an unstable system.
VERY IMPORTANT! Beta1 (build 3036) users must boot natively into Boot Camp and uninstall Parallels Tools for Boot Camp prior to running it in Beta2 (build 3094).
