In particular: + + * Clients should no longer format it specially in room timelines. + + * Clients and servers should no longer consider `m.room.aliases` when + [calculating the display name for a + room](https://matrix.org/docs/spec/client_server/r0.6.0#calculating-the-display-name-for-a-room). + + (Note: servers follow the room display-name algorithm when calculating + room names for certain types of push notification.) + + * A future room version will remove the special [authorization +rules](https://matrix.org/docs/spec/rooms/v1#authorization-rules) and +[redaction rules](https://matrix.org/docs/spec/client_server/r0.6.0#redactions). + + * [`m.room.canonical_alias`](https://matrix.org/docs/spec/client_server/r0.6.0#m-room-canonical-alias) + is extended to include a new `alt_aliases` property.

(Again, this is implemented in Synapse but does not appear to be + explicitly specced.) The `m.room.aliases` functionality should be removed, + and the `m.room.canonical_alias` functionality should be extended to cover + `alt_aliases`. + + The behaviour if the calling user has permission to delete the alias but + does not have permission to send `m.room.canonical_alias` events in the room + (for example, by virtue of being a "server administrator", or by being the + user that created the alias) is implementation-defined. It is *recommended* + that in this case, the alias is deleted anyway, and a successful response is + returned to the client. + + * A new api endpoint, `GET /_matrix/client/r0/rooms/{roomId}/aliases` is + added, which returns the list of aliases currently defined on the local + server for the given room. The response looks like: + + ```json + { + "aliases": [ + "#somewhere:example.com", + "#somewhereelse:example.com", + "#special_alias:example.com" + ] + } + ``` + + This API can be called by any current member of the room (calls from other + users result in `M_FORBIDDEN`). For rooms with `history_visibility` set to + `world_readable`, it can also be called by users outside the room. + + Servers might also choose to allow access to other users such as server + administrators. + +Various APIs are currently subject to implementation-defined access +restrictions. No change to the specification is introduced in this regard +(implementations will continue to be free to impose their own +restrictions). Nevertheless as part of this MSC it is useful to consider some +proposed changes to Synapse's implementation: + + * No change: `PUT /_matrix/client/r0/directory/room/{roomAlias}`: Synapse + only allows access to current members of the room, and also exposes some + configuration options which allow restriction of which users are allowed to + create aliases in general. + + * `DELETE /_matrix/client/r0/directory/room/{roomAlias}`: in this case, + currently Synapse restricts its use to the user that created the alias, and + server admins. + + It is proposed to extend this to local users who have a power-level + sufficient to send an `m.room.canonical_alias` event in the room that the + alias currently points to. + + * [`PUT /_matrix/client/r0/directory/list/room/{roomId}`](https://matrix.org/docs/spec/client_server/r0.6.0#put-matrix-client-r0-directory-list-room-roomid) + and the corresponding unspecced `DELETE` api (both of which set the + visibility of a room in the public directory): currently Synapse restricts + their use to server admins and local users who have a PL sufficient to send + an `m.room.aliases` event in the room (ignoring the special auth + rules). This will be changed to check against the PL required to send an + `m.room.canonical_alias` event. + +It is envisaged that Matrix clients will then change their "Room Settings" user +interface to display the aliases from `m.room.canonical_alias` instead of those +in `m.room.aliases`, as well as giving moderators the ability to update that +list. Clients might also wish to use the new `GET +/_matrix/client/r0/rooms/{roomId}/aliases` endpoint to obtain and display the +currently-available local aliases, though given that this list may be subject +to abuse, it should probably not be shown by default. + +### Future work + +This work isn't considered part of this MSC, but rather a potential extension +for the future. + + * It may be useful to be able to query remote servers for their alias + list. This could be done by extending `GET + /_matrix/client/r0/rooms/{roomId}/aliases` to take a `server_name` + parameter, and defining an API in the server_server spec which will expose + the requested information, subject to the calling homeserver having at least + one user with a right to see it. + + * Similarly, room moderators may wish to be able to delete aliases on a remote + server for their room. We could envisage a federation API which allows such + a request to be made, subject to the calling homeserver having at least one + moderator in the room. + +## Potential issues + +The biggest problem with this proposal is that existing clients, which rely on +`m.room.aliases` in one way or another, will lose functionality. In particular, +they may not know about aliases that exist, or they may look at outdated +`m.room.aliases` events that list aliases that no longer exist. However, since +`m.room.aliases` is best-effort anyway, these are both problems that exist to +some extent today. + +## Alternatives + +We considered continuing to use `m.room.aliases` to advertise room aliases +instead of `m.room.canonical_alias`, but the significant changes in semantics +made that seem inappropriate. + +We also considered using separate state events for each advertised alias, +rather than listing them all in one event. This might increase the number of +aliases which can be advertised, and help to reduce races when editing the +list. However, the 64KB limit of an event still allows room for hundreds of +aliases of any sane length, and we don't expect the list to be changing +frequently enough for races to be a practical concern. Ultimately the added +complexity seemed redundant. + +A previous suggestion was +[MSC2260](https://github.com/matrix-org/matrix-doc/issues/2260), which proposed +keeping `m.room.aliases` largely as-is, but giving room moderators tools to +control who can send them via room power-levels.
