+Changes in synapse v0.13.0 (2016-02-10)
+=======================================
+
+This version includes an upgrade of the schema, specifically adding an index to
+the ``events`` table. This may cause synapse to pause for several minutes the
+first time it is started after the upgrade.
+
+Changes:
+
+* Improve general performance (PR #540, #543. #544, #54, #549, #567)
+* Change guest user ids to be incrementing integers (PR #550)
+* Improve performance of public room list API (PR #552)
+* Change profile API to omit keys rather than return null (PR #557)
+* Add ``/media/r0`` endpoint prefix, which is equivalent to ``/media/v1/``
+  (PR #595)
+
+Bug fixes:
+
+* Fix bug with upgrading guest accounts where it would fail if you opened the
+  registration email on a different device (PR #547)
+* Fix bug where unread count could be wrong (PR #568)
+
+
+
+Changes in synapse v0.12.1-rc1 (2016-01-29)
+===========================================
+
+Features:
+
+* Add unread notification counts in ``/sync`` (PR #456)
+* Add support for inviting 3pids in ``/createRoom`` (PR #460)
+* Add ability for guest accounts to upgrade (PR #462)
+* Add ``/versions`` API (PR #468)
+* Add ``event`` to ``/context`` API (PR #492)
+* Add specific error code for invalid user names in ``/register`` (PR #499)
+* Add support for push badge counts (PR #507)
+* Add support for non-guest users to peek in rooms using ``/events`` (PR #510)
+
+Changes:
+
+* Change ``/sync`` so that guest users only get rooms they've joined (PR #469)
+* Change to require unbanning before other membership changes (PR #501)
+* Change default push rules to notify for all messages (PR #486)
+* Change default push rules to not notify on membership changes (PR #514)
+* Change default push rules in one to one rooms to only notify for events that
+  are messages (PR #529)
+* Change ``/sync`` to reject requests with a ``from`` query param (PR #512)
+* Change server manhole to use SSH rather than telnet (PR #473)
+* Change server to require AS users to be registered before use (PR #487)
+* Change server not to start when ASes are invalidly configured (PR #494)
+* Change server to require ID and ``as_token`` to be unique for AS's (PR #496)
+* Change maximum pagination limit to 1000 (PR #497)
+
+Bug fixes:
+
+* Fix bug where ``/sync`` didn't return when something under the leave key
+  changed (PR #461)
+* Fix bug where we returned smaller rather than larger than requested
+  thumbnails when ``method=crop`` (PR #464)
+* Fix thumbnails API to only return cropped thumbnails when asking for a
+  cropped thumbnail (PR #475)
+* Fix bug where we occasionally still logged access tokens (PR #477)
+* Fix bug where ``/events`` would always return immediately for guest users
+  (PR #480)
+* Fix bug where ``/sync`` unexpectedly returned old left rooms (PR #481)
+* Fix enabling and disabling push rules (PR #498)
+* Fix bug where ``/register`` returned 500 when given unicode username
+  (PR #513)
+
