+summary: Basic support for XEP-0463: MUC Affiliations Versioning
+---
+
+Introduction
+============
+
+This module implements [XEP-0463](https://xmpp.org/extensions/xep-0463.html),
+specifically version 0.2 of it. It does so without any additional storage
+requirements and everything needed is handled in-memory only.
+
+Details
+=======
+
+This module does not preserve a version history, it only knows about the state
+before and after a change and the current set of affiliations. This means that
+if affiliations are changed while a user device is offline, they will receive
+a full response when reconnecting with the room. This is in line with the
+behavior the XEP describes for the case of the client sending a version unknown
+to the server.
+
+Compatibility
+=============
+
+Tested only on Prosody 13.
