Qubes OS 4.0.1-rc1 has been released!

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.
