 - MagicDNS domains no longer contain usernames []()
  - This is in preperation to fix Headscales implementation of tags which currently does not correctly remove the link between a tagged device and a user. As tagged devices will not have a user, this will require a change to the DNS generation, removing the username, see [#1369](https://github.com/juanfont/headscale/issues/1369) for more information.
