Yesterday, the Qubes OS community announced the first release candidate of Qubes OS 4.0.1. This is the first of at least two planned point releases for version 4.0.

Qubes OS, a free and open source security-oriented operating system, aims to provide security through isolation. Virtualization in Qubes OS is performed by Xen; the user environments can be based on Fedora, Debian, Whonix, and Microsoft Windows.

The community announced the release of 3.2.1-rc1 one month ago. Since no serious problems have been discovered in 3.2.1-rc1, they plan to build the final version of Qubes 3.2.1 at the end of this week.

Features of Qubes OS 4.0.1-rc1

  • All 4.0 dom0 updates to date
  • Includes Fedora 29 TemplateVM
  • Debian 9 TemplateVM
  • Whonix 14 Gateway and Workstation TemplateVMs
  • Linux kernel 4.14

The next release candidate

The second release candidate, 4.0.1-rc2, will include a fix for the Nautilus bug reported in #4460 along with any other available fixes for bugs reported against this release candidate.
