The final step is to make sure that all of your VMs are running a supported operating system so that they're all receiving upstream security updates.
## Upgrading to stay on a supported release
The above covers routine updates.
Eventually, however, most operating system releases will reach [end-of-life (EOL)](https://fedoraproject.org/wiki/End_of_life), after which point they will no longer be supported.
This applies to [Qubes OS itself](/doc/supported-versions/#qubes-os) as well as operating systems used for TemplateVMs and StandaloneVMs, such as [Fedora](/doc/templates/fedora/) and [Debian](/doc/templates/debian/).
It is very important to use only supported releases, since generally only supported releases receive security updates.
This means that you must periodically upgrade to a newer release before your current release reaches EOL.
In the case of Qubes OS itself, we will always [announce](/news/categories/#releases) when a given Qubes OS release is approaching and has reached EOL, and we will provide [instructions for upgrading to the next stable supported Qubes OS release](/doc/upgrade/).
Again, you can always see the current support status for all Qubes OS releases [here](/doc/supported-versions/#qubes-os).
Periodic upgrades are also important for TemplateVMs and StandaloneVMs.
For example, you might be using a [Fedora TemplateVM](/doc/templates/fedora/).
The [Fedora Project](https://getfedora.org/) is independent of the Qubes OS Project.
They set their own [schedule](https://fedoraproject.org/wiki/Fedora_Release_Life_Cycle#Maintenance_Schedule) for when each Fedora release reaches [end-of-life](https://fedoraproject.org/wiki/End_of_life) (EOL).
They set their own [schedule](https://fedoraproject.org/wiki/Fedora_Release_Life_Cycle#Maintenance_Schedule) for when each Fedora release reaches EOL.
You can always find out when an operating system reaches EOL from the upstream project that maintains it, but we also make EOL [announcements](/news/categories/#announcements) and publish guides for official TemplateVM operating systems as a convenience to Qubes users.
When this happens, you should make sure to follow the guide to upgrade to a supported version of that operating system (see the [Fedora upgrade guides](/doc/templates/fedora/#upgrading) and the [Debian upgrade guides](/doc/templates/debian/#upgrading)).
The one exception is dom0, which [doesn't have to be upgraded](/doc/supported-versions/#note-on-dom0-and-eol).
The one exception to all this is the specific release used for dom0 (not to be confused with Qubes OS as a whole), which [doesn't have to be upgraded](/doc/supported-versions/#note-on-dom0-and-eol).
