description: 'This event is sent by a homeserver directly to inform of changes to the list of aliases it knows about for that room. The ``state_key`` for this event is set to the homeserver which owns the room alias. The entire set of known aliases for the room is the union of all the ``m.room.aliases`` events, one for each homeserver. Clients **should** check the validity of any room alias given in this list before presenting it to the user as trusted fact. The lists given by this event should be considered simply as advice on which aliases might exist, for which the client can perform the lookup to confirm whether it receives the correct room ID.'
