Release Notes: Host and guest support was added for OS X 10.8 "Mountain Lion" and Oracle Linux 6.3. Support for Windows 8 was improved, notably for 3D graphics. Up to 36 networks cards can now be used. The network I/O bandwidth of a VM can now be limited. The GUI can now group VMs, change some settings during runtime, and has an expert mode for wizards. The API for controlling guests was enhanced. Many bugs were fixed.

Release Notes: Support for cloning of VMs was implemented. The GUI was enhanced with wizards for creating new virtual disks and for copying virtual disks. The memory limit for 64-bit hosts was raised to 1TB. Experimental support for PCI passthrough for Linux hosts was added. A new network attachment mode "Generic Driver" offering an open plugin architecture was added. A new experimental WDDM graphics driver was added, supporting Windows Aero and providing Direct3D support using a cleaner approach. Experimental support for SATA hard disk hotplugging was implemented. Many minor bugs were fixed.

Release Notes: VirtualBox was reorganized into a base package and Extension Packs. The GUI, now called “VirtualBox Manager”, received major rework, supporting complete machine deletion, creation of desktop shortcuts, sortable VM list, and guest window preview. The VMM now supports more than 1.5/2 GB guest RAM on 32-bit hosts. New virtual hardware, an Intel ICH9 chipset and Intel HD Audio, was added. Open Virtualization Format support was improved, including support for OVA, and better performance on import and export. Other enhancements and various bugfixes were made.

Release Notes: Support was added for Mac OS X guests on Mac hardware. Page Fusion de-duplicates identical memory pages of Windows guests, potentially increasing the VM capacity or density. Memory Ballooning allows dynamic recuperation of VM memory. Virtual hot plugging and unplugging of CPUs is supported for guest OSs that allow for it. Support for the virtualization features of recent Intel CPUs was added. Further new features include in-hypervisor networking, a completely re-worked storage I/O subsystem, Remote Display Protocol (RDP) video acceleration, and deletion of snapshots while a VM is running.

Release Notes: Teleportation (live migration) was introduced. VM states can now be restored from arbitrary snapshots, and branched snapshots can be made. 2D video acceleration was added for Windows guests. Flexibility of storage attachments was improved. The network attachment type can now be changed while a VM is running. Significant performance improvements were made for PAE and AMD64 guests. Experimental support for EFI was added. Support for paravirtualized network adapters was added. 3D support was improved. Several other enhancements were made, and many bugs were fixed.

Release Notes: Guest SMP with up to 32 virtual CPUs is now supported on VT-x and AMD-V. Experimental Direct3D 8/9 support was added for Windows guests. Support for OpenGL 2.0 was added. Many bugs were fixed.

Release Notes: Support for many new features was added, such as OVF (Open Virtualization Format) appliance import and export, host-only networking mode, experimental USB support for OpenSolaris hosts, shared folders for Solaris and OpenSolaris guests, and OpenGL 3D acceleration for Linux and Solaris guests. Hypervisor optimizations with significant performance gains for high-context switching rates were made. The memory limit for VMs on 64-bit hosts was raised to 16GB. VT-x/AMD-V are now enabled by default for newly created virtual machines. Many other enhancements were made and bugs were fixed.

Release Notes: Support for hardware virtualization on Mac OS X hosts was added. Support for Intel Nehalem virtualization enhancements was added. 64-bit guests are now experimentally supported on 32-bit host operating systems. Experimental 3D acceleration via OpenGL was added. Experimental LsiLogic and BusLogic SCSI controllers were added. Full support for VMDK/VHD including snapshots was introduced. A new NAT engine with significantly better performance, reliability, and ICMP echo support was developed. Many other enhancements and bugfixes were made.

Release Notes: 64-bit guest support (64-bit hosts only). A new native Leopard user interface on Mac OS X hosts. The GUI was converted from Qt3 to Qt4 with many visual improvements. A guest property information interface. Host interface networking on Mac OS X hosts. Support for nested paging on modern AMD CPUs (a major performance gain). SATA asynchronous I/O (NCQ: Native Command Queuing) when accessing raw disks/partitions (major performance gain). Many other changes.
