Oracle's VirtualBox 3.2.8 has been released. This is a maintenance release that mainly focuses on bug fixes rather than new features. Although I don't think the changes in this release are as prolific as the fixes in 3.2.6, it's definitely worth downloading.
One key feature buried in the Changelog is the ability to attach one disk to several virtual machines. This is especially useful in clustered setups where multiple machines share a single filesystem.
If you haven't tried VirtualBox yet, I recommend it to anyone that has a need for a virtualized environment. It's great for developers who need to support different platforms and system administrators who need a compact test environment.
