According to the developers, the maintenance update features more than 50 changes and updates, including fixes for a variety of bugs found in VirtualBox 4.0.4, which added support for Ubuntu 11.04 guests.

Previously limited to 64 cores / hyper-threads, the latest release features the addition of support for up to 256 host cores (except for Windows hosts), support for host key combinations and the option to store snapshots in the VM directory.

All users are advised to upgrade. Multiple memory leaks have also been corrected.

Details about this maintenance update, including a full list of changes, can be found in the change log. VM VirtualBox 4.0.6 is available to download for Windows, Mac OS X, Linux and Solaris from the project's site, and documentation is provided. Both the base Oracle VM VirtualBox product source code and the binary are licensed under the GPLv2, while the Extension Pack mechanism, which allows third-party sources to add their own add-on functionality, is licensed under the PUEL.
