Module presence 

Presence: PUT/GET /presence/{userId}/status, the sync presence section, and m.presence EDUs between servers.

Optional: the presence cargo feature (default on) and the environment switch M4A_PRESENCE=off. Off, a PUT is accepted and forgotten, a GET says offline, sync carries no presence and no EDU is sent or applied.

The content of one user’s presence (as in m.presence events), if any is known.

create_schema

enabled

set

Record a presence change (own user or a remote one learned by EDU); returns the users to wake.

sync_events
