 Notes:
 
 ✰ Support for Ubuntu Focal [was dropped](https://github.com/freedomofpress/dangerzone/issues/1018)
 
-✢ Qubes OS support is done via the use of other OSes (e.g. Fedora or Debian) for the VMs, so the versions we support are tied to them.
+✢ Qubes OS support assumes the use of a Fedora template. The supported versions follow our general support for Fedora.
