This version is a major update. The following major new features were added:
- OVF (Open Virtualization Format) appliance import and export (see chapter 3.8, Importing and exporting virtual machines, User Manual page 55)
- Host-only networking mode (see chapter 6.7, Host-only networking, User Manual page 88)
- Hypervisor optimizations with significant performance gains for high context switching rates
- Raised the memory limit for VMs on 64-bit hosts to 16GB
- 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 and Solaris guests (see chapter 4.8, Hardware 3D acceleration (OpenGL), User Manual page 70)
- Added C API in addition to C++, Java, Python and Web Services
In addition, the following items were fixed and/or added:
- VMM: FreeBSD guest related fix for V86 ?ags (bug #2342)
- VMM: fixed guru meditation when booting an AsteriskNow Linux VM (bug #2342)
- VMM: fixed PGMPOOLKIND_FREE guru meditation (bugs #3356, #3431)

- USB: fixed BSOD on the host with certain USB devices (Windows hosts only; bug #1654)
- E1000: properly handle cable disconnects (bug #3421)
- VRDP: fixed hangs when VRDP server is enabled or disabled in runtime
- Shared folders: respect umask settings on Linux, OSX and Solaris hosts when creating files
- X11 guests: prevented setting the locale in vboxmouse, as this caused problems with Turkish locales (bug #3563)
- X11 guests: show the guest mouse pointer at the right position if the virtual desktop is larger than the guest resolution (bug #2306)
- Linux additions: fixed typo when detecting Xorg 1.6 (bug #3555)
- Solaris guests: added xpg4/xcu4 dependency to the guest additions installer (bug #3524)
- Windows guests: bind the VBoxMouse.sys filter driver to the correct guest pointing device (bug #1324)
- Windows hosts: fixed BSOD when starting a VM with enabled host interface (bug #3414)
- Linux hosts: do proper reference counting to prevent unloading the vboxnet?t module as long as this code is in use (bug #3104)
- Linux hosts: do not leave zombies of VBoxSysInfo.sh (bug #3586)
- 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 vms commands now default to compact format
- VBoxManage controlvm dvdattach did not work if the image was attached before
- VBoxManage: allow creation of all supported disk image variants
- VBoxManage showvminfo: don’t spam the release log if the additions don’t support statistics information (bug #3457)
- VBoxManage: big command line processing cleanup, the legacy single-dash options are deprecated and will be removed in the next major release, so switch to the new options now
- Hard disks: improved immutable disk support to auto-reset diff file at VM startup (related to bug #2772)
- GUI: enable the audio adapter by default for new VMs
- GUI: warn if VT-x/AMD-V is not operational when starting a 64-bit guest
