+Changes in synapse 0.5.4 (2014-12-03)
+=====================================
+
+ * Fix presence bug where some rooms did not display presence updates for
+   remote users.
+ * Do not log SQL timing log lines when started with "-v"
+ * Fix potential memory leak.
+
+Changes in synapse 0.5.3c (2014-12-02)
+======================================
+
+ * Change the default value for the `content_addr` option to use the HTTP
+   listener, as by default the HTTPS listener will be using a self-signed
+   certificate.
+
+Changes in synapse 0.5.3 (2014-11-27)
+=====================================
+
+ * Fix bug that caused joining a remote room to fail if a single event was not
+   signed correctly.
+ * Fix bug which caused servers to continuously try and fetch events from other
+   servers.
+
+Changes in synapse 0.5.2 (2014-11-26)
+=====================================
+
+Fix major bug that caused rooms to disappear from peoples initial sync.
+
+Changes in synapse 0.5.1 (2014-11-26)
+=====================================
+See UPGRADES.rst for specific instructions on how to upgrade.
+
+ * Fix bug where we served up an Event that did not match its signatures.
+ * Fix regression where we no longer correctly handled the case where a
+   homeserver receives an event for a room it doesn't recognise (but is in.)
+
 Changes in synapse 0.5.0 (2014-11-19)
 =====================================
 This release includes changes to the federation protocol and client-server API

+This is an attempt at bridging matrix clients into a Jitis meet room via Matrix
+video call.  It uses hard-coded xml strings overg XMPP BOSH. It can display one
+of the streams from the Jitsi bridge until the second lot of SDP comes down and
+we set the remote SDP at which point the stream ends. Our video never gets to
+the bridge.
