VMware Fusion 3.0 New Features:
http://communities.vmware.com/docs/DOC-10957

A list of the most interesting new features in VMware Workstation:

256-bit Encryption — Secure your virtual machines with AES256-bit encryption to prevent unauthorized users from accessing or running the configuration files.

Pause a Virtual Machine — Free your CPU resources instantaneously without powering off or suspending the virtual machine.

Four-Way SMP — Create and run virtual machines with a total of four processor cores, which can consist of four single-core processors, two dual-core processors, or one quad-core processor like the new Intel i7.

AutoProtect —Schedule snapshots of your virtual machine to be created at a regular interval to ensure that you always have a snapshot available to revert to when needed.

Virtual Printing — Print from virtual machines without mapping network printers or installing printer drivers in the virtual machine. With virtual printing enabled in the virtual machine setting, all of the printers installed on the host operating system are available in the guest operating system. This functionality is enabled through a partnership with ThinPrint, Inc.

Cross-Platform License Keys — Use the VMware Workstation 7.0 license key on both the Windows and Linux versions. Make sure you read the EULA for the terms and conditions that must be met when switching platforms.

Expand Virtual Disks — Increase the size of the virtual disk from within VMware Workstation. For Windows Vista and Windows 7 guests, the disk partitions can be adjusted without the use of additional software.

Compact Virtual Disks — Reclaim unused space from a virtual disk so that the host or another virtual machine can use it.

Drag and Drop Enhancements — Drag and drop enhancements include support for new file types including images and formatted text and extend the existing ability to drag and drop files to a broader set of guest and host operating systems.

Virtual Network Editor — User interface enhancements have simplified creating and configuring virtual networks.

IPv6 Support — Create a bridged connection to an IPv6 network on VMware Workstation virtual machines.

Fuse Mount for Linux — Use Fuse to mount .vmdk disks on to the file system of Linux hosts.
