+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
+  pull in the fix for SYWEB-361 so that the default client can display
+  HTML messages again(!)
+
+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)

+* 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 ``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)
+
+Changes in synapse v0.12.0 (2016-01-04)
+=======================================
+
+* Expose ``/login`` under ``r0`` (PR #459)
+
+Changes in synapse v0.12.0-rc3 (2015-12-23)
+===========================================
+
+* Allow guest accounts access to ``/sync`` (PR #455)
+* Allow filters to include/exclude rooms at the room level
+  rather than just from the components of the sync for each
+  room. (PR #454)
+* Include urls for room avatars in the response to ``/publicRooms`` (PR #453)
+* Don't set a identicon as the avatar for a user when they register (PR #450)
+* Add a ``display_name`` to third-party invites (PR #449)
+* Send more information to the identity server for third-party invites so that
+  it can send richer messages to the invitee (PR #446)
+* Cache the responses to ``/initialSync`` for 5 minutes. If a client
+  retries a request to ``/initialSync`` before the a response was computed
+  to the first request then the same response is used for both requests
+  (PR #457)
+* Fix a bug where synapse would always request the signing keys of
+  remote servers even when the key was cached locally (PR #452)
+* Fix 500 when pagination search results (PR #447)
+* Fix a bug where synapse was leaking raw email address in third-party invites
+  (PR #448)
+
+Changes in synapse v0.12.0-rc2 (2015-12-14)
+===========================================
+
+* Add caches for whether rooms have been forgotten by a user (PR #434)
+* Remove instructions to use ``--process-dependency-link`` since all of the
+  dependencies of synapse are on PyPI (PR #436)

+* Fix race updating presence in ``/events`` (PR #444)
+* Fix bug back-populating search results (PR #441)
+* Fix bug calculating state in ``/sync`` requests (PR #442)
+
+Changes in synapse v0.12.0-rc1 (2015-12-10)
+===========================================
+
+* Host the client APIs released as r0 by
+  https://matrix.org/docs/spec/r0.0.0/client_server.html
+  on paths prefixed by ``/_matrix/client/r0``. (PR #430, PR #415, PR #400)
+* Updates the client APIs to match r0 of the matrix specification.
+
+  * All APIs return events in the new event format, old APIs also include
+    the fields needed to parse the event using the old format for
+    compatibility. (PR #402)
+  * Search results are now given as a JSON array rather than
+    a JSON object (PR #405)
+  * Miscellaneous changes to search (PR #403, PR #406, PR #412)
+  * Filter JSON objects may now be passed as query parameters to ``/sync``
+    (PR #431)
+  * Fix implementation of ``/admin/whois`` (PR #418)
+  * Only include the rooms that user has left in ``/sync`` if the client
+    requests them in the filter (PR #423)
+  * Don't push for ``m.room.message`` by default (PR #411)
+  * Add API for setting per account user data (PR #392)
+  * Allow users to forget rooms (PR #385)
+
+* Performance improvements and monitoring:
+
+  * Add per-request counters for CPU time spent on the main python thread.
+    (PR #421, PR #420)
+  * Add per-request counters for time spent in the database (PR #429)
+  * Make state updates in the C+S API idempotent (PR #416)
+  * Only fire ``user_joined_room`` if the user has actually joined. (PR #410)
+  * Reuse a single http client, rather than creating new ones (PR #413)
+
+* Fixed a bug upgrading from older versions of synapse on postgresql (PR #417)
+
+Changes in synapse v0.11.1 (2015-11-20)
+=======================================
+
+* Add extra options to search API (PR #394)
+* Fix bug where we did not correctly cap federation retry timers. This meant it
+  could take several hours for servers to start talking to ressurected servers,
+  even when they were receiving traffic from them (PR #393)
+* Don't advertise login token flow unless CAS is enabled. This caused issues
+  where some clients would always use the fallback API if they did not
+  recognize all login flows (PR #391)
+* Change /v2 sync API to rename ``private_user_data`` to ``account_data``
+  (PR #386)
+* Change /v2 sync API to remove the ``event_map`` and rename keys in ``rooms``
+  object (PR #389)

+==========================================
+
+* Fix bug with python packaging
+
+Changes in synapse v0.10.0 (2015-09-03)

+
+No change from release candidate.
+
+Changes in synapse v0.10.0-rc6 (2015-09-02)
+===========================================

+
+* Allow UTF-8 filenames for upload. (PR #259)
+
+Changes in synapse v0.10.0-rc3 (2015-08-25)
+===========================================
+
+* Add ``--keys-directory`` config option to specify where files such as
+  certs and signing keys should be stored in, when using ``--generate-config``
+  or ``--generate-keys``. (PR #250)
+* Allow ``--config-path`` to specify a directory, causing synapse to use all
+  \*.yaml files in the directory as config files. (PR #249)

+  or typing events, reducing the CPU cost of each pusher.
+
+
+Changes in synapse v0.10.0-rc1 (2015-08-21)
+===========================================
+
+Also see v0.9.4-rc1 changelog, which has been amalgamated into this release.
+
+General:
+
+* Upgrade to Twisted 15 (PR #173)
+* Add support for serving and fetching encryption keys over federation.
+  (PR #208)
+* Add support for logging in with email address (PR #234)
+* Add support for new ``m.room.canonical_alias`` event. (PR #233)
+* Change synapse to treat user IDs case insensitively during registration and
+  login. (If two users already exist with case insensitive matching user ids,
+  synapse will continue to require them to specify their user ids exactly.)
+* Error if a user tries to register with an email already in use. (PR #211)
+* Add extra and improve existing caches  (PR #212, #219, #226, #228)
+* Batch various storage request (PR #226, #228)
+* Fix bug where we didn't correctly log the entity that triggered the request
+  if the request came in via an application service (PR #230)
+* Fix bug where we needlessly regenerated the full list of rooms an AS is
+  interested in. (PR #232)
+* Add support for AS's to use v2_alpha registration API (PR #210)
+
+
+Configuration:
+
+* Add ``--generate-keys`` that will generate any missing cert and key files in
+  the configuration files. This is equivalent to running ``--generate-config``
+  on an existing configuration file. (PR #220)
+* ``--generate-config`` now no longer requires a ``--server-name`` parameter
+  when used on existing configuration files. (PR #220)
+* Add ``--print-pidfile`` flag that controls the printing of the pid to stdout
+  of the demonised process. (PR #213)
+
+Media Repository:
+
+* Fix bug where we picked a lower resolution image than requested. (PR #205)
+* Add support for specifying if a the media repository should dynamically
+  thumbnail images or not. (PR #206)
+
+Metrics:
+
+* Add statistics from the reactor to the metrics API. (PR #224, #225)
+
+Demo Homeservers:
+
+* Fix starting the demo homeservers without rate-limiting enabled. (PR #182)
+* Fix enabling registration on demo homeservers (PR #223)
+
+
+Changes in synapse v0.9.4-rc1 (2015-07-21)
+==========================================
+
+General:
+
+* Add basic implementation of receipts. (SPEC-99)
+* Add support for configuration presets in room creation API. (PR  #203)
+* Add auth event that limits the visibility of history for new users.
+  (SPEC-134)
+* Add SAML2 login/registration support. (PR  #201. Thanks Muthu Subramanian!)
+* Add client side key management APIs for end to end encryption. (PR #198)
+* Change power level semantics so that you cannot kick, ban or change power
+  levels of users that have equal or greater power level than you. (SYN-192)
+* Improve performance by bulk inserting events where possible. (PR #193)
+* Improve performance by bulk verifying signatures where possible. (PR #194)
+
+
+Configuration:
+
+* Add support for including TLS certificate chains.
+
+Media Repository:
+
+* Add Content-Disposition headers to content repository responses. (SYN-150)
+
+
+Changes in synapse v0.9.3 (2015-07-01)
+======================================
+
+No changes from v0.9.3 Release Candidate 1.
+
+Changes in synapse v0.9.3-rc1 (2015-06-23)
+==========================================
+
+General:
+
+* Fix a memory leak in the notifier. (SYN-412)
+* Improve performance of room initial sync. (SYN-418)
+* General improvements to logging.
+* Remove ``access_token`` query params from ``INFO`` level logging.
+
+Configuration:
+
+* Add support for specifying and configuring multiple listeners. (SYN-389)
+
+Application services:
+
+* Fix bug where synapse failed to send user queries to application services.
+
+Changes in synapse v0.9.2-r2 (2015-06-15)
+=========================================
+
+Fix packaging so that schema delta python files get included in the package.
+
+Changes in synapse v0.9.2 (2015-06-12)
+======================================
+
+General:
+
+* Use ultrajson for json (de)serialisation when a canonical encoding is not
+  required. Ultrajson is significantly faster than simplejson in certain
+  circumstances.
+* Use connection pools for outgoing HTTP connections.
+* Process thumbnails on separate threads.
+
+Configuration:
+
+* Add option, ``gzip_responses``, to disable HTTP response compression.
+
+Federation:
+
+* Improve resilience of backfill by ensuring we fetch any missing auth events.
+* Improve performance of backfill and joining remote rooms by removing
+  unnecessary computations. This included handling events we'd previously
+  handled as well as attempting to compute the current state for outliers.
+
+
+Changes in synapse v0.9.1 (2015-05-26)
+======================================
+
+General:
+
+* Add support for backfilling when a client paginates. This allows servers to
+  request history for a room from remote servers when a client tries to
+  paginate history the server does not have - SYN-36
+* Fix bug where you couldn't disable non-default pushrules - SYN-378
+* Fix ``register_new_user`` script - SYN-359
+* Improve performance of fetching events from the database, this improves both
+  initialSync and sending of events.
+* Improve performance of event streams, allowing synapse to handle more
+  simultaneous connected clients.
+
+Federation:
+
+* Fix bug with existing backfill implementation where it returned the wrong
+  selection of events in some circumstances.
+* Improve performance of joining remote rooms.
+
+Configuration:
+
+* Add support for changing the bind host of the metrics listener via the
+  ``metrics_bind_host`` option.
+ 
+
+Changes in synapse v0.9.0-r5 (2015-05-21)
+=========================================
+
+* Add more database caches to reduce amount of work done for each pusher. This
+  radically reduces CPU usage when multiple pushers are set up in the same room.
+
 Changes in synapse v0.9.0 (2015-05-07)

+Upgrading Synapse
+=================
+
+Before upgrading check if any special steps are required to upgrade from the
+what you currently have installed to current version of synapse. The extra

+
+Upgrading to v0.11.0
+====================
+
+This release includes the option to send anonymous usage stats to matrix.org,
+and requires that administrators explictly opt in or out by setting the
+``report_stats`` option to either ``true`` or ``false``.
+
+We would really appreciate it if you could help our project out by reporting
+anonymized usage statistics from your homeserver. Only very basic aggregate
+data (e.g. number of users) will be reported, but it helps us to track the
+growth of the Matrix community, and helps us to make Matrix a success, as well
+as to convince other networks that they should peer with us.
