Room History Visibility
=======================
9 years ago
Whether a member of a room can see the events that happened in a room from
before they joined the room is controlled by the ``history_visibility`` key
of the ``m.room.history_visibility`` state event. The valid values for
``history_visibility`` are:
- ``shared``
- ``invited``
- ``joined``
9 years ago
By default if no ``history_visibility`` is set it is assumed to be ``shared``.
The rules governing whether a user is allowed to see an event depend solely on
9 years ago
the state of the room at that event:
1. If the user was joined, allow.
2. If the user was invited and the ``history_visibility`` was set to
``invited`` or ``shared``, allow.
3. If the user was neither invited nor joined but the ``history_visibility``
was set to ``shared``, allow.
4. Otherwise, deny.
