Qubes OS releases are normally supported for six months after each subsequent major or minor release (see Supported Versions and Version Scheme). In accordance with this policy, Qubes 3.1, which was released on 2016-03-09, is scheduled to reach end-of-life (EOL) on 2017-03-29 — six months after Qubes 3.2 was released on 2016-09-29. We strongly urge all current Qubes 3.1 users to upgrade to Qubes 3.2 or newer before 2017-03-29. As always, newer releases are available on the downloads page.
