The following major new features were added:<\/p>\n<ul>\n<li><strong>Support for cloning of VMs<\/strong> (bug #5853, see the manual for more information): full clones can be created through the GUI and VBoxManage, linked clones only through VBoxManage<\/li>\n<li>GUI: enhanced wizard for creating new virtual disks<\/li>\n<li>GUI: new wizard for copying virtual disks<\/li>\n<li>GUI: keep the aspect ratio in scale mode (Windows and OSX hosts only; bug #7822)<\/li>\n<li>VMM: raised the memory limit for 64-bit hosts to 1TB<\/li>\n<li>Experimental support for PCI passthrough for Linux hosts, see the manual for more information<\/li>\n<li>Windows guests: Experimental WDDM graphics driver, supporting Windows Aero (bug #4607) and providing Direct3D support using a cleaner approach (no need to install the guest drivers in Safe Mode anymore)<\/li>\n<li>Guest Additions: status of modules and features can now be queried separately by the frontends<\/li>\n<li>Networking: new network attachment mode &#8220;Generic Driver&#8221;, which offers an open plugin architecture for arbitrary and separately distributable virtual network implementations<\/li>\n<li>Host-only Networking: fixed host crash in kernels prior to 2.6.29<\/li>\n<li>New Networking Mode UDP Tunnel: allows to interconnect VMs running on different hosts easily and transparently, see the manual for more information<\/li>\n<li>Experimental support for SATA hard disk hotplugging available with VBoxManage<\/li>\n<li>Solaris hosts: New Crossbow based bridged networking driver for Solaris 11 build 159 and above<\/li>\n<\/ul>\n<p>In addition, the following items were fixed and\/or added:<\/p>\n<ul>\n<li>VMM: more SMP timer fixes<\/li>\n<li>VMM: fixed sporadic recompiler crashes with SMP guests<\/li>\n<li>VMM: many small fixes<\/li>\n<li>GUI: when reverting to a snapshot, ask for taking a snapshot of the current state<\/li>\n<li>GUI: added a View menu<\/li>\n<li>GUI: added a setting for the promiscuous mode policy for internal networks, bridged networks and host-only networks<\/li>\n<li>GUI: added slider for setting the CPU execution cap allowing to limit the amount of CPU time spent for the execution of the guest, see the manual for more information.<\/li>\n<li>GUI: the VM description is editable during the runtime of a VM (bug #1551)<\/li>\n<li>GUI: added proxy settings (bug #2870)<\/li>\n<li>GUI: made the number of SATA ports configurable<\/li>\n<li>GUI: decrease time before showing the VM configuration dialog<\/li>\n<li>VBoxManage: more convenient configuration of storage controller attachments by automatically determining the port or device parameter when a storage controller has only one port or device per port<\/li>\n<li>VBoxManage: changed syntax of the guestcontrol command group, fixed various bugs, removed obsolete options<\/li>\n<li>VBoxBalloonCtrl: new service for automatic dynamic adjustment of the balloon size for running VMs<\/li>\n<li>Settings: machine names and snapshot names are not allowed to be a valid UUID<\/li>\n<li>Settings: provide better diagnostics if a single medium is used twice in a VM configuration<\/li>\n<li>Settings: provide better diagnostics for errors in medium create\/merge\/clone operations, and fix memory leaks in error cases<\/li>\n<li>Storage: ATA\/SATA drives can be marked as non-rotational, i.e. the guest OS will detect them as a SSD if supported, which can improve performance<\/li>\n<li>Storage: virtual CD\/DVD images will be detached if the guest ejects the medium, unless the drive is marked to handle ejects only on a temporary basis<\/li>\n<li>Storage: the medium UUID can be changed again when attaching a medium for the first time, which allows using images which are exact duplicates including the UUID<\/li>\n<li>Storage: fixed possible data corruption under certain circumstances with VHD and Parallels images (bug #9150)<\/li>\n<li>Storage: fixed unnecessary expansion when cloning differential images in VDI format<\/li>\n<li>Storage: fixed detection code to handle empty files for VDI and VMDK format<\/li>\n<li>Storage: fixed access to CD\/DVD images beyond 4GB when using the SATA controller (bug #8592)<\/li>\n<li>Floppy: several bugs have been fixed<\/li>\n<li>Floppy: make it possible to unmount a host floppy disk (bug #6651)<\/li>\n<li>BIOS: disk-related structures are now checksummed correctly (bug #8739)<\/li>\n<li>USB: many fixes for the Windows USB host driver<\/li>\n<li>NAT: reduced memory footprint<\/li>\n<li>Networking: fixed the problem with segmentation offloading when several VMs are transmitting in parallel<\/li>\n<li>Networking: workaround for a bug in wireshark when operating directly on a capture file created by VirtualBox<\/li>\n<li>Serial: announce the serial devices in the ACPI tables to make Windows guests find the virtual hardware (bug #7411)<\/li>\n<li>VRDP: support

fail<\/li>\n<li>VBoxSVC: fixed regression when several clients trigger autostart simultaneously<\/li>\n<li>Main: fixed incorrect handling of the medium location for media which are not file based (e.g. iSCSI), which resulted in confusing location values in many places<\/li>\n<li>JAX-WS client bindings: fixed resource leak<\/li>\n<li>Sources: fixed USB 2.0 support using extension packs for non-official builds<\/li>\n<li>Mac OS X hosts: fixed non-VT-x mode on Lion hosts<\/li>\n<li>Windows hosts: fixed copy&#8217;n&#8217;paste in the GUI and for the VM window (bug #4491)<\/li>\n<li>Windows hosts (64-bit only): enabled removing of all mediums when removing a VM<\/li>\n<li>Windows hosts (64-bit only): enabled live snapshot deletion<\/li>\n<li>Windows hosts: use
