    240 '''!VirtualBox 3.2.0''' (released 2010-05-18)[[BR]][[BR]]
    241 This version is a major update. The following major new features were added:
    242  * Following the acquisition of Sun Microsystems by Oracle Corporation, the product is now called ''Oracle VM !VirtualBox'' and all references were changed without impacting compatibility
    243  * Experimental support for Mac OS X Server guests (see the [/manual/ch03.html#intro-macosxguests manual] for more information)
    244  * Memory ballooning to dynamically in- or decrease the amount of RAM used by a VM (64-bit hosts only) (see the [/manual/ch04.html#guestadd-balloon manual] for more information)
    245  * Page Fusion automatically de-duplicates RAM when running similar VMs thereby increasing capacity. Currently supported for Windows guests on  64-bit hosts (see the [/manual/ch04.html#guestadd-pagefusion manual] for more information)
    246  * CPU hot-plugging for Linux (hot-add and hot-remove) and certain Windows guests (hot-add only) (see the [/manual/ch09.html#cpuhotplug manual] for more information)
    247  * New Hypervisor features: with both VT-x/AMD-V on 64-bit hosts, using large pages can improve performance (see the [/manual/ch10.html#nestedpaging manual] for more information); also, on VT-x, unrestricted guest execution is now supported (if nested paging is enabled with VT-x, real mode and protected mode without paging code runs faster, which mainly speeds up guest OS booting)
    248  * Support for deleting snapshots while the VM is running
    249  * Support for multi-monitor guest setups in the GUI for Windows guests (see the [/manual/ch03.html#settings-display manual] for more information)
    250  * USB tablet/keyboard emulation for improved user experience if no Guest Additions are available (see the [/manual/ch03.html#settings-motherboard manual] for more information).
    251  * !LsiLogic SAS controller emulation (see the [/manual/ch05.html#harddiskcontrollers manual] for more information)
    252  * RDP video acceleration (see the [/manual/ch07.html#vrdp-videochannel manual] for more information)
    253  * NAT engine configuration via API and VBoxManage
    254  * Use of host I/O cache is now configurable (see the [/manual/ch05.html#iocaching manual] for more information)
    255  * Guest Additions: added support for executing guest applications from the host system (replaces the automatic system preparation feature; see the [/manual/ch04.html#guestadd-guestcontrol manual] for more information)
    256  * OVF: enhanced OVF support with custom namespace to preserve settings that are not part of the base OVF standard
    257 
    258 In addition, the following items were fixed and/or added:
    259  * VMM: fixed Windows 2000 guest crash when configured with a large amount of RAM (bug #5800)
    260  * Linux/Solaris guests: PAM module for automatic logons added
    261  * GUI: guess the OS type from the OS name when creating a new VM
    262  * GUI: added VM setting for passing the time in UTC instead of passing the local host time to the guest (bug #1310)
    263  * GUI: fixed seamless mode on secondary monitors (bugs #1322 and #1669)
    264  * GUI: offer to download the user manual in the OSE version (bug #6442)
    265  * GUI: allow to set an empty host key to disallow any host key combination (bug #684)
    266  * GUI: allow to restrict the possible actions when shutting down the VM from the GUI
    267  * Main: allow to start a VM even if a virtual DVD or floppy medium is not accessible
    268  * Settings: be more robust when saving the XML settings files

    274  * 3D support: fixed VM crashes when using ''ARB_IMAGING'' (bug #6014)
