This page details the level and period of support for releases of operating
|
|
systems in the Qubes ecosystem.
|
|
|
|
## Qubes OS
|
|
|
|
Qubes OS releases are supported for **six months** after each subsequent major
|
|
or minor release (see [Version Scheme](/doc/version-scheme/)). The current
|
|
release and past major releases are always available on the
|
|
[Downloads](/downloads/) page, while all ISOs, including past minor releases,
|
|
are available from our [download mirrors](/downloads/#mirrors).
|
|
|
|

|
| Release 1 | 2012-09-03 | 2015-03-26 | Unsupported |
|
|
| Release 2 | 2014-09-26 | 2016-04-01 | Unsupported |
|

### Note on patch releases
|
|
|
|
Please note that patch releases, such as 3.2.1 and 4.0.1, do not designate
|
|
separate, new major or minor releases of Qubes OS. Rather, they designate their
|
|
respective major or minor releases, such as 3.2 and 4.0, inclusive of all
|
|
package updates up to a certain point. For example, installing Release 4.0 and
|
|
fully updating it results in the same system as installing Release 4.0.1.
|
|
Therefore, patch releases are not displayed as separate rows on any of the
|
|
tables on this page.
|
|
|
|
## Dom0
|
|
|
|
The table below shows the OS used for dom0 in each Qubes OS release.
|
|
|
|
| Qubes OS | Dom0 OS |
|
|
| ----------- | --------- |
|
|
| Release 1 | Fedora 13 |
|
|
| Release 2 | Fedora 18 |
|
|
| Release 3.0 | Fedora 20 |
|
|
| Release 3.1 | Fedora 20 |
|
|
| Release 3.2 | Fedora 23 |
|
|
| Release 4.0 | Fedora 25 |
|
|
| Release 4.1 | Fedora 32 |
|
|
| Release 4.2 | Fedora 37 |
|
|
|
|
### Note on dom0 and EOL
|
|
|
|
Dom0 is isolated from domUs. DomUs can access only a few interfaces, such as
|
|
Xen, device backends (in the dom0 kernel and in other VMs, such as the NetVM),
|
|
and Qubes tools (gui-daemon, qrexec-daemon, etc.). These components are
|
|
[security-critical](/doc/security-critical-code/), and we provide updates for
|
|
all of them (when necessary), regardless of the support status of the base
|
|
distribution. For this reason, we consider it safe to continue using a given
|
|
base distribution in dom0 even after it has reached end-of-life (EOL).
|
|
|
|
## Templates
|
|
|
|
The following table shows select [template](/doc/templates/) releases that are
|
|
currently supported. Currently, only [Fedora](/doc/templates/fedora/) and
|
|
[Debian](/doc/templates/debian/) templates are officially supported by the
|
|
Qubes OS Project. [Whonix](https://www.whonix.org/wiki/Qubes) templates are
|
|
supported by our partner, the [Whonix Project](https://www.whonix.org/). Qubes
|
|
support for each template ends when that upstream release reaches end-of-life
|
|
(EOL), even if that release is included in the table below. Please see below for
|
|
distribution-specific notes.
|
|
|
|
It is the responsibility of each distribution to clearly notify its users in
|
|
advance of its own EOL dates, and it is users' responsibility to heed these
|
|
notices by upgrading to supported releases. As a courtesy to Qubes users, we
|
|
attempt to pass along any upstream EOL notices we receive for
|
|
officially-supported templates, but our ability to do this reliably is
|
|
dependent on the upstream distribution's practices. If a distribution provides
|
|
a mailing list similar to [qubes-announce](/support/#qubes-announce), which
|
|
allows us to receive only very important, infrequent messages, including EOL
|
|
announcements, we are much more likely to be able to pass along EOL notices to
|
|
Qubes users reliably. Qubes users can always check the EOL status of an
|
|
upstream release on the upstream distribution's website (see [Fedora
|
|
EOL](https://fedoraproject.org/wiki/End_of_life) and [Debian
|
|
Releases](https://wiki.debian.org/DebianReleases)).
|
|
|
|
| Qubes OS | Fedora | Debian | Whonix |
|
|
| ----------- | ------ | ------ | ------ |
|
|
| Release 4.1 | 38 | 11, 12 | 16 |
|
|
| Release 4.2 | 38 | 12 | 17 |
|
|
|
|
### Note on Debian support
|
|
|
|
Debian releases have two EOL dates: regular and [long-term support
|
|
(LTS)](https://wiki.debian.org/LTS). See [Debian Production
|
|
Releases](https://wiki.debian.org/DebianReleases#Production_Releases) for a
|
|
chart that illustrates this. Qubes support ends at the *regular* EOL date,
|
|
*not* the LTS EOL date, unless a specific exception has been made.
|
|
|
|
### Note on Whonix support
|
|
|
|
[Whonix](https://www.whonix.org/wiki/Qubes) templates are supported by our
|
|
partner, the [Whonix Project](https://www.whonix.org/). The Whonix Project has
|
|
set its own support policy for Whonix templates in Qubes. Please see the
|
|
[Qubes-Whonix version support policy](https://www.whonix.org/wiki/About#Qubes_Hosts)
|
|
for details.
