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.
Marek Marczykowski-Górecki has announced the release of Qubes OS 4.0.1, an updated version of the projects security-focused Linux distribution which allows users to "compartmentalise" computing tasks into isolated compartments called qubes. This new release is mostly a bug-fix and security update and is recommended for all new Qubes installations: "We are pleased to announce the release of Qubes 4.0.1. This is the first stable point release of Qubes 4.0. It includes many updates over the initial 4.0 release, in particular: all 4.0 dom0 updates to date, including a lot of bug fixes and improvements for GUI tools; Fedora 29 TemplateVM; Debian 9 TemplateVM; Whonix 14 Gateway and Workstation TemplateVMs; Linux kernel 4.14. If youre currently using an up-to-date Qubes 4.0 installation (including updated Fedora 29, Debian 9, and Whonix 14 templates), then your system is already equivalent to a Qubes 4.0.1 installation. No action is needed. Similarly, if youre currently using a Qubes 4.0.1 release candidate and youve followed the standard procedure for keeping it up-to-date, then your system is equivalent to a 4.0.1 stable installation.
