Qubes OS is a security-oriented, Fedora-based desktop Linux distribution whose main concept is "security by isolation" by using domains implemented as lightweight Xen virtual machines. It attempts to combine two contradictory goals: how to make the isolation between domains as strong as possible, mainly due to clever architecture that minimises the amount of trusted code, and how to make this isolation as seamless and easy as possible.
Andrew David Wong has announced the release of Qubes OS 4.0, a major new update of the projects security-oriented desktop Linux distribution based on Fedora 25: "After nearly two years in development and countless hours of testing, were pleased to announce the stable release of Qubes OS 4.0. Version 4.0 includes several fundamental improvements to the security and functionality of Qubes OS: the Qubes Admin API; Qubes Core Stack version 3; fully virtualized virtual machines for enhanced security; multiple, flexible Disposable VM templates; a more expressive, user-friendly Qubes RPC policy system; a powerful new VM volume manager that makes it easy to keep VMs on external drives; enhanced TemplateVM security via split packages and network interface removal; more secure backups with scrypt for stronger key derivation and enforced encryption; re-written command-line tools with new options.
