[spoiler][spoiler=VirtualBox 3.2.0 (released 2010-05-18)]

This version is a major update. The following major new features were added:

• 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


• Experimental support for Mac OS X Server guests (see the manual for more information)


• Memory ballooning to dynamically in- or decrease the amount of RAM used by a VM (64-bit hosts only) (see the manual for more information)
