Latest Version
VirtualBox 4.3.20.96996

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 signi?cant 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 ?xed and/or added:

* VMM: FreeBSD guest related ?x for V86 ?ags (bug #2342)
* VMM: ?xed guru meditation when booting an AsteriskNow Linux VM (bug #2342)
* VMM: ?xed PGMPOOLKIND_FREE guru meditation (bugs #3356, #3431)
* VMM: ?xed Windows XP boot hang (guest PAE + nested paging only)
* VMM: allow mixing of VT-x/AMD-V and software virtualization
* VMM: ?xed extremely slow safe mode booting in e.g. Windows 2008 (VT-x/AMD-V only)
* VMM: signi?cant speedup of certain GRUB boot loaders (e.g. Solaris) (VT-x/AMD-V only)
* VMM: real-mode IOPL ?x for DOS guests (VT-x only)
* VMM: ?xed VT-x detection with certain BIOSes that enable VT-x, but don’t set the lock bit in MSR_IA32_FEATURE_CONTROL
* VMM: ?xed hibernation issues on Windows XP hosts (VT-x only; bug #1794)
* VMM: properly emulate RDMSR from the TSC MSR, should ?x some NetBSD guests
* VMM: emulate RDPMC; ?xes Windows guests crashes when using the Kaspersky virus scanner (bug #1778)
* NAT: ?xed truncated downloads (FTP) (bug #3257)
* NAT: blocked UDP packets caused a crash (bug #3426)
* NAT: allow to con?gure the next server and the boot ?le via VBoxManage (bug #2759)
* IDE: ?xed hard disk upgrade from XML-1.2 settings (bug #1518)
* Hard disk: support more VMDK ?le variants (including ?xed-size ESX server images)
* Hard disks: refuse to start the VM if a disk image is not writable
* USB: further reduced host CPU utilization for OHCI and EHCI; the “VBoxInternal/Devices/usb-ohci/0/Con?g/FrameRate” CFG key is no longer necessary and no longer supported
* USB: ?xed BSOD on the host with certain USB devices (Windows hosts only; bug #1654)
* E1000: properly handle cable disconnects (bug #3421)
* VRDP: ?xed hangs when VRDP server is enabled or disabled in runtime
* Shared folders: respect umask settings on Linux, OSX and Solaris hosts when creating ?les
* 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: ?xed 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 ?lter driver to the correct guest pointing device (bug #1324)
* Windows hosts: ?xed 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: ?xes 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
