'''!VirtualBox 3.0.0''' (released 2009-06-30)[[BR]][[BR]]
This version is a major update. The following major new features were added:
 * Guest SMP with up to 32 virtual CPUs (VT-x and AMD-V only; see [/manual/UserManual.html#settings-processor chapter 3.7.2.2] of the [http://download.virtualbox.org/virtualbox/3.0.0/UserManual.pdf user manual])
 * Windows guests: ability to use Direct3D 8/9 applications / games (experimental; see [/manual/UserManual.html#guestadd-3d chapter 4.8] of the [http://download.virtualbox.org/virtualbox/3.0.0/UserManual.pdf user manual])
 * Support for OpenGL 2.0 for Windows, Linux and Solaris guests
In addition, the following items were fixed and/or added:
 * Solaris hosts: allow suspend/resume on the host when a VM is running (bug #3826)
 * Solaris hosts: loosen the restriction for contiguous physical memory under certain conditions
 * Mac OS X hosts: fixed guest PAE
 * Linux hosts: kernel module compile fixes for 2.6.31 (bug #4264)
 * VMM: fixed occasional guru meditation when loading a saved state (VT-x only)
 * VMM: eliminated IO-APIC overhead with 32 bits guests (VT-x only, some Intel CPUs don’t support this feature (most do); bug #638)
 * VMM: fixed 64 bits CentOS guest hangs during early boot (AMD-V only; bug #3927)
 * VMM: performance improvements for certain PAE guests (e.g. Linux 2.6.29+ kernels)
 * VMM: some Windows guests detected a completely wrong CPU frequency (bug #2227)
 * VMM: fixed hanging and unkillable VM processes (bug #4040)
 * VMM: fixed random infrequent guest crashes due XMM state corruption (Win64 hosts only)
 * VMM: performance improvements for network I/O (VT-x/AMD-V only)
 * GUI: added mini toolbar for fullscreen and seamless mode (Thanks to Huihong Luo)
 * GUI: redesigned settings dialogs
 * GUI: allow to create/remove more than one host-only network adapters (non Windows hosts)
 * GUI: display estimated time for long running operations (e.g. OVF import/export)
 * GUI: fixed rare hangs when open the OVF import/export wizards (bug #4157)
 * 3D support: fixed VM crashes for client applications using incorrect OpenGL states
 * 3D support: fixed memory corruption when querying for supported texture compression formats
 * 3D support: fixed incorrect rendering of glDrawRangeElements
 * 3D support: fixed memory leak when using VBOs
 * 3D support: fixed glew library detection
 * 3D support: fixed random textures corruption
 * VRDP: support Windows 7 RDP client
 * Networking: fixed another problem with TX checksum offloading with Linux kernels up to version 2.6.18
 * NAT: fixed “open ports on virtual router 10.0.2.2 - 513, 514” (forum)
 * NAT: allow to configure socket and internal parameters
 * NAT: allow to bind sockets to specific interface
 * PXE boot: significant performance increase (VT-x/AMD-V only)
 * VHD: properly write empty sectors when cloning of VHD images (bug #4080)
 * VHD: fixed crash when discarding snapshots of a VHD image
 * VHD: fixed access beyond the block bitmap which could lead to arbitrary crashes
 * VBoxManage: fixed incorrect partition table processing when creating VMDK files giving raw partition access (bug #3510)
 * VBoxManage: support cloning to existing image file
 * OVF: several OVF 1.0 compatibility fixes
 * OVF: fixed exporting of disk images when multiple virtual machines are exported at once
 * Virtual mouse device: eliminated micro-movements of the virtual mouse which were confusing some applications (bug #3782)
 * Shared Folders: sometimes a file was created using the wrong permissions (2.2.0 regression; bug #3785)
 * Shared Folders: allow to change file attributes from Linux guests and use the correct file mode when creating files
 * Shared Folders: some content was incorrectly written under certain conditions (bug #1187)
 * Shared Folders: fixed incorrect file timestamps, when using Windows guest on a Linux host (bug #3404)
 * X11 clipboard: fix duplicate end of lines (bug #4270)
 * X11 guests: a number of shared clipboard fixes
 * Linux guests: Guest Additions support for SUSE Linux Enterprise Desktop 11
 * Linux guests: new daemon vboxadd-service to handle time synchronization and guest property lookup
 * Linux guests: implemented guest properties (OS info, logged in users, basic network information)
 * Windows host installer: !VirtualBox Python API can now be installed automatically (requires Python and Win32 Extensions installed)
 * USB: Support for high-speed isochronous endpoints has been added. In addition, read-ahead buffering is performed for input endpoints (currently Linux hosts only). This should allow additional devices to work, notably webcams (bug #242).
 * USB: fixed error handling for some USB dongles
 * Web service: fixed inability to handle NULL pointers for object arguments, which are valid values for a lot of APIs, in both the raw and the object-oriented web service.
 * Web service: object-oriented bindings for JAX-WS did not exhibit interface inheritance correctly, fixed
 * Web service: added support for IDisplay and IGuest interfaces, which were previously unavailable
 * Registration dialog uses Sun Online accounts now
