 Changes in develop
 ==================
 
- * Add initial implementation of the `query auth` fedeartion API, allowing
-   servers to agree on whether an event should be allowed or rejected.
- * Persist events we have rejected from federation, fixing the bug where
-   servers would keep requesting the same events.
- * Various performance improvements, including:

 Changes in synapse 0.6.0 (2014-12-16)
 =====================================
 
- * Add new API for media upload and download that supports thumbnailing.
- * Replicate media uploads over multiple homeservers so media is always served
-   to clients from their local homeserver.  This obsoletes the
-   --content-addr parameter and confusion over accessing content directly
-   from remote homeservers.
- * Implement exponential backoff when retrying federation requests when
-   sending to remote homeservers which are offline.
- * Implement typing notifications.
- * Fix bugs where we sent events with invalid signatures due to bugs where
-   we incorrectly persisted events.
- * Improve performance of database queries involving retrieving events.

 ======================================
 
- * Change the default value for the `content_addr` option to use the HTTP

-   certificate.

 =====================================
 
- * 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.
