http://www.virtualbox.org/ 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 chapter 3.7.2.2, “Processor” tab, page 48) ‧ Windows guests: ability to use Direct3D 8/9 applications / games (experimental; see chapter 4.8, Hardware 3D acceleration (OpenGL and DirectX 8/9), page 71) ‧ 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 #11187) ‧ 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 --
