It’s a significant upgrade so it would seem.. The big thing that hits me is now you can use more then 1.5GB of ram!.. The virtual motherboard supports PCI Express, along with SATA, and the ability to read Apple virtual disk images…
I see there is more improvements in the 3d support as well… Although I’ve been using VMWare Fusion as of late, but it’s always good for more alternatives.
Download VirtualBox from Oracle, here.
It still supports Windows, Linux, OSX and Solaris, all x86/x64.
