+## Streaming
+
+There is an additional `user:pleroma_chat` stream. Incoming chat messages will make the current chat be sent to this `user` stream. The `event` of an incoming chat message is `pleroma:chat_update`. The payload is the updated chat with the incoming chat message in the `last_message` field.

+
+## User muting and thread muting
+
+Both user muting and thread muting can be done for only a certain time by adding an `expires_in` parameter to the API calls and giving the expiration time in seconds.
+
+## Not implemented
+
+Pleroma is generally compatible with the Mastodon 2.7.2 API, but some newer features and non-essential features are omitted. These features usually return an HTTP 200 status code, but with an empty response. While they may be added in the future, they are considered low priority.
