Today we released a new version of Sun VirtualBox. I think the feature list is a bit short for a new major release but okay. Version 2.0 introduce the following new features:

• support for 64-bit guest OSes (Microsoft Windows Vista and Red Hat Enterprise Linux 5)
• support for AMD RVI
• support for Microsoft VHD virtual disk format
• new interface for Apple Mac OS edition (native 10.5 Leopard GUI)
• Python API (for Solaris and Linux hosts only)

I think that the deveoloper go the right way. Support for the Microsoft virtual disk format for example is a great new feature. With the possibility to use VMware´s disk format you are able to run all your vm´s from the big guys in the virtualization world.
