+Room Version 6
+==============
+
+This room version builds on `version 5 <v5.html>`_ while changing various
+authorization rules performed on events.

+
+
+Client considerations
+---------------------
+
+The redaction algorithm has changed from `room version 1 <v1.html>`_ to remove
+all rules against events of type ``m.room.aliases``. Room versions 2, 3, 4, and
+5 all use v1's redaction algorithm. The algorithm is otherwise unchanged.
+
+
+Server implementation components
+--------------------------------
+
+.. WARNING::
+   The information contained in this section is strictly for server implementors.
+   Applications which use the Client-Server API are generally unaffected by the
+   intricacies contained here. The section above regarding client considerations
+   is the resource that Client-Server API use cases should reference.
+
+
+Room version 6 makes the following alterations to algorithms described in `room version 5 <v5.html>`_.
+
+Redactions
+~~~~~~~~~~
+
+As mentioned in the client considerations portion of this specification, all
+special meaning has been removed for events of type ``m.room.aliases``. The
+algorithm is otherwise unchanged.
+
+Authorization rules for events
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Like redactions, all rules relating specifically to events of type ``m.room.aliases``
+are removed. They must still pass authorization checks relating to state events.
+
+The remaining rules are the same as in `room version 3 <v3.html#authorization-rules-for-events>`_
+(the last inherited room version to specify the authorization rules).
