Supported Versions
|
|
==================
|
|
|
|
Qubes OS
|
|
--------
|
|
Qubes OS releases are supported for **six months** after each subsequent major
|
|
or minor release (see [Version Scheme]). The current release and past major
|
|
releases are always available on the [Downloads] page, while all ISOs, including
|
|
past minor releases, are available from our [download mirrors].
|
|
|
|
| Qubes OS | Start Date | End Date | Status |
|
|
| ------------- | ---------- | ---------- | ----------------------- |
|
|
| Release 1 | 2012-09-03 | 2015-03-26 | Old, unsupported |
|
|
| Release 2 | 2014-09-26 | 2016-04-01 | Old, unsupported |
|
|
| Release 3.0 | 2015-10-01 | 2016-09-09 | Old, unsupported |
|
|
| Release 3.1 | 2016-03-09 | 2017-03-29 | Old, unsupported |
|
|
| Release 3.2 | 2016-09-29 | 2019-03-28 | Old, unsupported |
|
|

|
|
| Release 4.1 | TBA | TBA | [In development][4.1] |
|

|
### 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 4.0 and 3.2, 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 |
|
|
|
|
### 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], 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 EOL (end-of-life).
|
|
|
|
|
|
TemplateVMs
|
|
-----------
|
|
The table below shows the [TemplateVM] versions supported by each Qubes OS
|
|
release. Currently, only Fedora, Debian, and Whonix TemplateVMs are officially supported.
|
|
|
|
| Qubes OS | Fedora | Debian | Whonix |
|
|
| ------------- | ---------------------------- | --------------------------------------------- | ------ |
|
|
| Release 1 | 18, 20 | None | None |
|
|
| Release 2 | 21 | None | None |
|
|
| Release 3.0 | 21, 22\*, 23 | 7 ("wheezy")\*, 8 ("jessie") | None |
|
|
| Release 3.1 | 21, 22\*, 23 | 7 ("wheezy")\*, 8 ("jessie"), 9 ("stretch")\* | None |
|
|
| Release 3.2 | 23\*, 24\*, 25\*, 26, 27, 28 | 8 ("jessie"), 9 ("stretch") | 13, 14 |
|
|
| Release 4.0 | 26, 27, 28, 29 | 8 ("jessie"), 9 ("stretch") | 13, 14 |
|
|
|
|
\* Denotes versions for which we have published the packages but have not done
|
|
extensive testing.
|
|
|
|
|
|
Whonix
|
|
------
|
|
|
|
[Whonix] is an advanced feature in Qubes OS.
|
|
Those who wish to use it must 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.
