Main: eliminate the use of SysV semaphores on all host OSes other than Windows, namely Linux, Solaris and Mac OS X, with the consequence that no system reconfiguration is needed to run more than approximately 100 VMs.

Main: new event queue implementation which does not use the host’s native event queue for processing VirtualBox events anymore.

Settings: the per-VM hwvirtextexcl setting has been replaced by a global hwvirtexclusive property.

Settings: limit depth of snapshot tree to 250 levels, as more will lead to decreased performance and may trigger crashes.

Settings: global and per-VM default frontend configuration, useful to select the use of alternative VM frontends.

Storage: added floppy formatting emulation (NB: cannot be used to change existing media geometry).

Storage: significantly improved performance of large ATAPI PIO transfers (BeOS, Minix 3 guests affected).Storage: implemented AHA-154x compatibility mode in the emulated BusLogic SCSI HBA.Teleportation: made it work again (bug #9455).Snapshots: made live snapshots work again (bug #9255).GUI: use the number of physical presented processor cores instead of the number of logical processor cores to check if the users assigned too many virtual CPUs to the guest.GUI, VBoxManage: when unregistering a VM, also unregister the hard disk images which are used exclusively (bug #10311).GUI: HID LEDs synchronization when switching between guest window(s) and host (Mac OS X hosts only).GUI: numerous minor internal cleanups and bug fixes.VMM: allow to activate VT-x while in SMX mode and provide more information if that is not possible.VMM: changed order of actions in emulated task switch (bug #10532).

VMM: fixed losing host NMIs while in VT-x guest-context.

VMM: significantly improved performance of NetWare 5.x/6.x guests on host systems without nested paging support.

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

NAT service (see the manual for more information).

NAT: experimental virtual router mode: several VMs are attached to the same internal network and share one.

Guest Control: implemented IGuestFile support.

Guest Control: guest sessions now are running in dedicated, impersonated session processes (needs at least Guest Additions 4.3 installed).Added SCSI CD-ROM emulation, including boot support.Added experimental support for webcam passthrough complementing USB passthrough (see the manual for more information).GUI: video capturing support (bug #4766).GUI: keyboard shortcuts management (input page of global preferences extended with possibility to edit general keyboard shortcuts for VirtualBox Manager and Virtual Machine).GUI: extended messaging mechanism (new non-modal popup overlays used to show non-critical warnings and provide user with additional information).VMM: introduced a lightweight instruction interpreter for situations not handled by hardware virtualization.VMM: major rewrite of the VT-x code and the AMD-V code including many bug fixes and performance improvements.The following major new features were added:
