VirtualBox 4.0.8

Oracle has released VirtualBox 4.0.8 today.

Oracle VM VirtualBox (the full title) is virtualization software for x86 platforms (Intel/AMD) and allows you to run various Guest OSes under Mac OS X, Windows, Linux, and other host operating systems. It is similar in functionality to Parallels Desktop and VMWare Fusion as far as Mac OS X users are concerned. There is a limited functionality when it comes to running Mac OS X guest sessions, although a Mac as the host machine is required.

It’s being listed as a maintenance release, with no new main features or additions.
