+Changes in synapse v0.7.0 (2015-02-12)
+======================================
+
+* Add initial implementation of the query auth federation 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 federation performance improvements, including:
+
+  - Add in memory caches on queries such as:
+
+     * Computing the state of a room at a point in time, used for
+       authorization on federation requests.
+     * Fetching events from the database.
+     * User's room membership, used for authorizing presence updates.
+
+  - Upgraded JSON library to improve parsing and serialisation speeds.
+
+* Add default avatars to new user accounts using pydenticon library.
+* Correctly time out federation requests.
+* Retry federation requests against different servers.
+* Add support for push and push rules.
+* Add alpha versions of proposed new CSv2 APIs, including ``/sync`` API.
+
 Changes in synapse 0.6.1 (2015-01-07)
 =====================================
 
- * Major optimizations to improve performance of initial sync and event sending
-   in large rooms (by up to 10x)
- * Media repository now includes a Content-Length header on media downloads.
- * Improve quality of thumbnails by changing resizing algorithm.

 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.

-   remote users.
- * Do not log SQL timing log lines when started with "-v"
- * Fix potential memory leak.

-   listener, as by default the HTTPS listener will be using a self-signed

-   signed correctly.
