Joanna Rutkowska has announced the release of Qubes OS 3.2, a new stable release of the Fedora-based desktop Linux distribution whose main concept is "security by isolation" by using domains implemented as lightweight Xen virtual machines. From the release announcement: "I'm happy to announce that today we're releasing Qubes OS 3.2. This is an incremental improvement over the 3.1 version that we released earlier this year. A lot of work went into making this release more polished, more stable and easier to use than our previous releases. One major feature that we've improved upon in this release is our integrated management infrastructure, which was introduced in Qubes 3.1. Whereas before it was only possible to manage whole VMs, it is now possible to manage the insides of VMs as well. The principal challenge we faced was how to allow such a tight integration of the management engine software (for which we use Salt) with potentially untrusted VMs without opening a large attack surface on the (complex) management code."
