http://www.virtualbox.org/

This version is a major update. The following major new features were added:

-Support for hardware virtualization (VT-x and AMD-V) on Mac OS X hosts
-Support for 64-bit guests on 32-bit host operating systems (experimental;
see user manual, chapter 1.6, 64-bit guests, page 16)
-Added support for Intel Nehalem virtualization enhancements (EPT and VPID;
see user manual, chapter 1.2, Software vs. hardware virtualization (VT-x and
AMD-V), page 10))
-Experimental 3D acceleration via OpenGL (see user manual, chapter 4.8,
Hardware 3D acceleration (OpenGL), page 66)
-Experimental LsiLogic and BusLogic SCSI controllers (see user manual,
chapter 5.1, Hard disk controllers: IDE, SATA (AHCI), SCSI, page 70)
-Full VMDK/VHD support including snapshots (see user manual, chapter 5.2,
Disk image files (VDI, VMDK, VHD), page 72)
-New NAT engine with significantly better performance, reliability and ICMP
echo (ping) support (bugs #1046, #2438, #2223, #1247)
-New Host Interface Networking implementations for Windows and Linux hosts
with easier setup (replaces TUN/TAP on Linux and manual bridging on Windows)

In addition, the following items were fixed and/or added:

-VMM: significant performance improvements for VT-x (real mode execution)
-VMM: support for hardware breakpoints (VT-x and AMD-V only; bug #477)
-VMM: VGA performance improvements for VT-x and AMD-V
-VMM: Solaris and OpenSolaris guest performance improvements for AMD-V
(Barcelona family CPUs only)
-VMM: fixed guru meditation while running the Dr. Web virus scanner (software
virtualization only; bug #1439)
-VMM: deactivate VT-x and AMD-V when the host machine goes into suspend mode;
reactivate when the host machine resumes (Windows, Mac OS X & Linux hosts;
bug #1660)
-VMM: fixed guest hangs when restoring VT-x or AMD-V saved states/snapshots
-VMM: fixed guru meditation when executing a one byte debug instruction (VT-x
only; bug #2617)
-VMM: fixed guru meditation for PAE guests on non-PAE hosts (VT-x)
-VMM: disallow mixing of software and hardware virtualization execution in
general (bug #2404)
-VMM: fixed black screen when booting OS/2 1.x (AMD-V only)
-GUI: pause running VMs when the host machine goes into suspend mode (Windows
& Mac OS X hosts)
-GUI: resume previously paused VMs when the host machine resumes after
suspend (Windows & Mac OS X hosts)
-GUI: save the state of running or paused VMs when the host machine’s
battery reaches critical level (Windows hosts)
-GUI: properly restore the position of the selector window when running on
the compiz window manager
-GUI: properly restore the VM in seamless mode (2.0 regression)
-GUI: warn user about non optimal memory settings
-GUI: structure operating system list according to family and version for
improved usability
-GUI: predefined settings for QNX guests
-IDE: improved ATAPI passthrough support
-Networking: added support for up to 8 Ethernet adapters per VM
-Networking: fixed issue where a VM could lose connectivity after a reboot
-iSCSI: allow snapshot/diff creation using local VDI file
-iSCSI: improved interoperability with iSCSI targets
-Graphics: fixed handling of a guest video memory which is not a power of two
(bug #2724)
-VBoxManage: fixed bug which prevented setting up the serial port for direct
device access.
-VBoxManage: added support for VMDK and VHD image creation
-VBoxManage: added support for image conversion (VDI/VMDK/VHD/RAW)
-Solaris hosts: added IPv6 support between host and guest when using host
interface networking
-Mac OS X hosts: added ACPI host power status reporting
-API: redesigned storage model with better generalization
-API: allow attaching a hard disk to more than one VM at a time
-API: added methods to return network configuration information of the host
system
-Shared Folders: performance and stability fixes for Windows guests
(Microsoft Office Applications)
