Oracle has just released the stable version of VirtualBox 4.0 – a free and multi-platform application for running virtual machines.
Edition 4.0 is a pretty significant update. The most important change is a completely new architecture. VirtualBox is now built from the base component and a set of additional modules. Such a structure will facilitate the extension and updating of the functionality of individual elements. In addition, the user interface (now called VirtualBox Manager) has been redesigned. It gained a lot of useful features, such as scaling of the virtual machine screen and many other.
