# Supported Versions
|
|
|
|
This page details the level and period of support for versions 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).
|
|
|
|
| Qubes OS | Start Date | End Date | Status |
|
|
| ----------- | ---------- | ---------- | --------------------- |
|
|
| Release 1 | 2012-09-03 | 2015-03-26 | Unsupported |
|
|
| Release 2 | 2014-09-26 | 2016-04-01 | Unsupported |
|
|
| Release 3.0 | 2015-10-01 | 2016-09-09 | Unsupported |
|
|
| Release 3.1 | 2016-03-09 | 2017-03-29 | Unsupported |
|
|
| Release 3.2 | 2016-09-29 | 2019-03-28 | Unsupported |
|
|
| Release 4.0 | 2018-03-28 | TBA | Supported |
|
|
| Release 4.1 | TBA | TBA | [In development](https://github.com/QubesOS/qubes-issues/issues?utf8=%E2%9C%93&q=is%3Aissue+milestone%3A%22Release+4.1%22+) |
|
|
|
|
### Note on point releases
|
|
|
|
Please note that point releases, such as 3.2.1 and 4.0.1, do not designate separate, new versions 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, point 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 |
|
|
|
|
### 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).
|
|
|
|
## TemplateVMs
|
|
|
|
The following table shows select [TemplateVM](/doc/templates/) versions that are currently supported.
|
|
Currently, only [Fedora](/doc/templates/fedora/) and [Debian](/doc/templates/debian/) TemplateVMs are officially supported by the Qubes OS Project.
|
|
[Whonix](/doc/whonix/) TemplateVMs are supported by our partner, the [Whonix Project](https://www.whonix.org/).
|
|
Qubes support for each TemplateVM ends when that upstream release reaches end-of-life (EOL), unless otherwise noted.
|
|
In the case of Debian, support ends at regular EOL, not [LTS](https://wiki.debian.org/LTS) EOL, unless otherwise noted.
|
|
See [below](#note-on-whonix-support) for Whonix support details.
|
|
For upstream EOL information, see [Fedora EOL](https://fedoraproject.org/wiki/End_of_life) and [Debian EOL](https://wiki.debian.org/DebianReleases).
|
|
|
|
| Qubes OS | Fedora | Debian | Whonix |
|
|
| ----------- | ------ | ---------------------------- | ------ |
|
|
| Release 4.0 | 32, 33 | 9 ("stretch"), 10 ("buster") | 15 |
|
|
| Release 4.1 | 32, 33 | 10 ("buster") | 15 |
|

### Note on Whonix support
|
|
|
|
[Whonix](/doc/whonix/) TemplateVMs are supported by our partner, the [Whonix Project](https://www.whonix.org/).
|
|
The Whonix Project has set its own support policy for Whonix TemplateVMs in Qubes.
|
|
|
|
This policy requires Whonix TemplateVM users to stay reasonably close to the cutting edge by upgrading to new stable versions of Qubes OS and Whonix TemplateVMs within a month of their respective releases.
|
|
To be precise:
|
|
|
|
* One month after a new stable version of Qubes OS is released, Whonix TemplateVMs will no longer be supported on any older version of Qubes OS.
|
|
This means that users who wish to continue using Whonix TemplateVMs on Qubes must always upgrade to the latest stable Qubes OS version within one month of its release.
|
|
|
|
* One month after new stable versions of Whonix TemplateVMs are released, older versions of Whonix TemplateVMs will no longer be supported.
|
|
This means that users who wish to continue using Whonix TemplateVMs on Qubes must always upgrade to the latest stable Whonix TemplateVM versions within one month of their release.
|
|
|
|
We aim to announce both types of events one month in advance in order to remind users to upgrade.
