VirtualBox 3.2.0

(2010.05.18)

Changes in 3.2.0

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 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)
