We’re pleased to announce the release of Qubes 4.0.1! This is the first stable patch 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

Qubes 4.0.1 is available on the Downloads page.

What is a patch release?

A patch release does not designate a separate, new major or minor release of Qubes OS. Rather, it designates its respective major or minor release (in this case, 4.0) inclusive of all updates up to a certain point. Installing Qubes 4.0 and fully updating it results in the same system as installing Qubes 4.0.1.

What should I do?

If you’re 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 you’re currently using a Qubes 4.0.1 release candidate (4.0.1-rc1 or 4.0.1-rc2), and you’ve followed the standard procedure for keeping it up-to-date, then your system is equivalent to a 4.0.1 stable installation, and no additional action is needed.

If you’re currently using Qubes 4.0 but don’t have these new templates installed yet, we recommend that you follow the appropriate documentation to do so:

Regardless of your current OS, if you wish to install (or reinstall) Qubes 4.0 for any reason, then the 4.0.1 ISO will make this more convenient and secure, since it bundles all Qubes 4.0 updates to date. It will be especially helpful for users whose hardware is too new to be compatible with the original Qubes 4.0 installer.
