Supported OpenStack versions

OpenStack release cadence follows Ubuntu release cadence. This means that a new version of OpenStack is released twice a year: in April and in October. Those are shipped with new versions of Ubuntu, however, since Canonical recommends using Ubuntu LTS in production environments, new versions of OpenStack are also available on Ubuntu LTS version through the Ubuntu Cloud Archive.
