+=======================================
+
+* Fix bug where ``/sync`` would occasionally return events in the wrong room.
+
+Changes in synapse v0.13.2 (2016-02-11)
+=======================================
+
+* Fix bug where ``/events`` would fail to skip some events if there had been
+  more events than the limit specified since the last request (PR #570)
+
+Changes in synapse v0.13.1 (2016-02-10)
+=======================================
+
+* Bump matrix-angular-sdk (matrix web console) dependency to 0.6.8 to

+
+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)

+Halp!! Synapse eats all my RAM!
+===============================
+
+Synapse's architecture is quite RAM hungry currently - we deliberately
+cache a lot of recent room data and metadata in RAM in order to speed up
+common requests.  We'll improve this in future, but for now the easiest
+way to either reduce the RAM usage (at the risk of slowing things down)
+is to set the almost-undocumented ``SYNAPSE_CACHE_FACTOR`` environment
+variable.  Roughly speaking, a SYNAPSE_CACHE_FACTOR of 1.0 will max out
+at around 3-4GB of resident memory - this is what we currently run the
+matrix.org on.  The default setting is currently 0.1, which is probably
+around a ~700MB footprint.  You can dial it down further to 0.02 if
+desired, which targets roughly ~512MB.  Conversely you can dial it up if
+you need performance for lots of users and have a box with a lot of RAM.

+    HTTP endpoint for extracting data from synapse.
+
+    The streams of data returned by the endpoint are controlled by the
+    parameters given to the API. To return a given stream pass a query
+    parameter with a position in the stream to return data from or the
+    special value "-1" to return data from the start of the stream.
+
+    If there is no data for any of the supplied streams after the given
+    position then the request will block until there is data for one
+    of the streams. This allows clients to long-poll this API.
+
+    The possible streams are:
+
+    * "streams": A special stream returing the positions of other streams.
+    * "events": The new events seen on the server.
+    * "presence": Presence updates.
+    * "typing": Typing updates.
+    * "receipts": Receipt updates.
+    * "user_account_data": Top-level per user account data.
+    * "room_account_data: Per room per user account data.
+    * "tag_account_data": Per room per user tags.
+    * "backfill": Old events that have been backfilled from other servers.
+    * "push_rules": Per user changes to push rules.
+    * "pushers": Per user changes to their pushers.
+
+    The API takes two additional query parameters:
+
+    * "timeout": How long to wait before returning an empty response.
+    * "limit": The maximum number of rows to return for the selected streams.
+
+    The response is a JSON object with keys for each stream with updates. Under
+    each key is a JSON object with:
+
+    * "position": The current position of the stream.
+    * "field_names": The names of the fields in each row.
+    * "rows": The updates as an array of arrays.
+
+    There are a number of ways this API could be used:
+
+    1) To replicate the contents of the backing database to another database.
+    2) To be notified when the contents of a shared backing database changes.
+    3) To "tail" the activity happening on a server for debugging.
+
+    In the first case the client would track all of the streams and store it's
+    own copy of the data.
+
+    In the second case the client might theoretically just be able to follow
+    the "streams" stream to track where the other streams are. However in
+    practise it will probably need to get the contents of the streams in
+    order to expire the any in-memory caches. Whether it gets the contents
+    of the streams from this replication API or directly from the backing
+    store is a matter of taste.
+
+    In the third case the client would use the "streams" stream to find what
+    streams are available and their current positions. Then it can start
+    long-polling this replication API for new data on those streams.
