This version is a major update. The following major new features were added:
- OVF (Open Virtualization Format) appliance import and export
- Host-only networking mode
- Hypervisor optimizations with significant performance gains for high context switching rates
- VT-x/AMD-V are enabled by default for newly created virtual machines
- USB (OHCI & EHCI) is enabled by default for newly created virtual machines (Qt GUI only)
- Experimental USB support for OpenSolaris hosts
- Shared folders for Solaris and OpenSolaris guests
- OpenGL 3d acceleration for Linux guests
- Experimental support for OS X 10.6 (Snow Leopard) hosts running both the 64-bit and the 32-bit kernel
- VMM: FreeBSD guest related fix for V86 flags (bug #2342)
- VMM: Fixed guru meditation when booting an AsteriskNow Linux VM (bug #2342)
- VMM: Fixed PGMPOOLKIND_FREE guru meditation (bugs #3356, #3431)
- VMM: Fixed Windows XP boot hang (guest PAE + nested paging only)
- VMM: Allow mixing of VT-x/AMD-V and software virtualization
- VMM: fixed extremely slow safe mode booting in e.g. Windows 2008 (VT-x/AMD-V only)
- VMM: significant speedup of certain Grub boot loaders (e.g. Solaris) (VT-x/AMD-V only)
- VMM: real-mode IOPL fix for DOS guests (VT-x only)
- VMM: fixed VT-x detection with certain BIOSes that enable VT-x, but don't set the lock bit in MSR_IA32_FEATURE_CONTROL
- NAT: Truncated downloads with NAT (ftp) (bug #3257)
- NAT: Blocked UDP packets cause crash (bug #3426)

- VRDP: fixed hangs when VRDP server is enabled or disabled in runtime
- X11 guests: show the guest mouse pointer at the right position if the virtual desktop is larger than the guest resolution (bug #2306)
- Solaris guests: added xpg4/xcu4 dependency to the guest additions installer (bug #3524)

- Linux installers: fixes for Slackware, Arch Linux and Linux from Scratch systems
- Windows installers: Combined installer executable which contains both (32- and 64-bit) architectures
- VBoxManage: less cryptic command-line error messages
- VBoxManage: 'list vm' commands now default to compact format
- Hard disks: improved immutable disk support to auto-reset diff file at VM startup
- GUI: enable the audio adapter by default for new VMs
- GUI: warn if VT-x/AMD-V is not operational when starting a 64 bits guest
- GUI: deactivate 64 bits guest support when the host CPU does not support VT-x/AMD-V
