-Changes in synapse v0.30.0 (2018-05-24)
-==========================================
-
-'Server Notices' are a new feature introduced in Synapse 0.30. They provide a
-channel whereby server administrators can send messages to users on the server.
-
-They are used as part of communication of the server policies (see ``docs/consent_tracking.md``),
-however the intention is that they may also find a use for features such
-as "Message of the day".
-
-This feature is specific to Synapse, but uses standard Matrix communication mechanisms,
-so should work with any Matrix client. For more details see ``docs/server_notices.md``
-
-Further Server Notices/Consent Tracking Support:
-
-* Allow overriding the server_notices user's avatar (PR #3273)
-* Use the localpart in the consent uri (PR #3272)
-* Support for putting %(consent_uri)s in messages (PR #3271)
-* Block attempts to send server notices to remote users (PR #3270)
-* Docs on consent bits (PR #3268)
-
-
-
-Changes in synapse v0.30.0-rc1 (2018-05-23)
-==========================================
-
-Server Notices/Consent Tracking Support:
-
-* ConsentResource to gather policy consent from users (PR #3213)
-* Move RoomCreationHandler out of synapse.handlers.Handlers (PR #3225)
-* Infrastructure for a server notices room (PR #3232)
-* Send users a server notice about consent (PR #3236)
-* Reject attempts to send event before privacy consent is given (PR #3257)
-* Add a 'has_consented' template var to consent forms (PR #3262)
-* Fix dependency on jinja2 (PR #3263)
-

-
-* Cohort analytics (PR #3163, #3241, #3251)
-* Add lxml to docker image for web previews (PR #3239) Thanks to @ptman!

-Changes in synapse v0.29.1 (2018-05-17)
-==========================================
-Changes:
-
-* Update docker documentation (PR #3222)
-
-Changes in synapse v0.29.0 (2018-05-16)
-===========================================
-Not changes since v0.29.0-rc1
-
-Changes in synapse v0.29.0-rc1 (2018-05-14)
-===========================================
-
-Notable changes, a docker file for running Synapse (Thanks to @kaiyou!) and a
-closed spec bug in the Client Server API. Additionally further prep for Python 3
-migration.
-
-Potentially breaking change:
-
-* Make Client-Server API return 401 for invalid token (PR #3161).
-
-  This changes the Client-server spec to return a 401 error code instead of 403
-  when the access token is unrecognised. This is the behaviour required by the
-  specification, but some clients may be relying on the old, incorrect
-  behaviour.
-
-  Thanks to @NotAFile for fixing this.

-
-Changes in synapse v0.28.1 (2018-05-01)
-=======================================
-
-SECURITY UPDATE
-
-* Clamp the allowed values of event depth received over federation to be
-  [0, 2^63 - 1].  This mitigates an attack where malicious events
-  injected with depth = 2^63 - 1 render rooms unusable.  Depth is used to
-  determine the cosmetic ordering of events within a room, and so the ordering
-  of events in such a room will default to using stream_ordering rather than depth
-  (topological_ordering).
-
-  This is a temporary solution to mitigate abuse in the wild, whilst a long term solution
-  is being implemented to improve how the depth parameter is used.
-
-  Full details at
-  https://docs.google.com/document/d/1I3fi2S-XnpO45qrpCsowZv8P8dHcNZ4fsBsbOW7KABI
-
-* Pin Twisted to <18.4 until we stop using the private _OpenSSLECCurve API.

-
-
-Changes in synapse v0.9.1 (2015-05-26)
-======================================
-

-  radically reduces CPU usage when multiple pushers are set up in the same room.
-
-Changes in synapse v0.9.0 (2015-05-07)
-======================================
-
-General:
-
-* Add support for using a PostgreSQL database instead of SQLite. See

-  contrib/systemd. Contributed Ivan Shapovalov.
-
-Federation:
-
-* Add key distribution mechanisms for fetching public keys of unavailable
-  remote home servers. See `Retrieving Server Keys`_ in the spec.
-
-Configuration:
-
-* Add support for multiple config files.
-* Add support for dictionaries in config files.
-* Remove support for specifying config options on the command line, except
-  for:
-
-  * ``--daemonize`` - Daemonize the home server.
-  * ``--manhole`` - Turn on the twisted telnet manhole service on the given
-    port.
-  * ``--database-path`` - The path to a sqlite database to use.
-  * ``--verbose`` - The verbosity level.
-  * ``--log-file`` - File to log to.
-  * ``--log-config`` - Python logging config file.
-  * ``--enable-registration`` - Enable registration for new users.
-
-Application services:
-
-* Reliably retry sending of events from Synapse to application services, as per
-  `Application Services`_ spec.
-* Application services can no longer register via the ``/register`` API,
-  instead their configuration should be saved to a file and listed in the
-  synapse ``app_service_config_files`` config option. The AS configuration file
-  has the same format as the old ``/register`` request.
-  See `docs/application_services.rst`_ for more information.

-General:
-
-* Add support for registration fallback. This is a page hosted on the server
-  which allows a user to register for an account, regardless of what client
-  they are using (e.g. mobile devices).
-
-* Added new default push rules and made them configurable by clients:
-
-  * Suppress all notice messages.
-  * Notify when invited to a new room.
-  * Notify for messages that don't match any rule.
-  * Notify on incoming call.
-
-Federation:
-
-* Added per host server side rate-limiting of incoming federation requests.
-* Added a ``/get_missing_events/`` API to federation to reduce number of
-  ``/events/`` requests.
-
-Configuration:
-
-* Added configuration option to disable registration:
-  ``disable_registration``.
-* Added configuration option to change soft limit of number of open file
-  descriptors: ``soft_file_limit``.
-* Make ``tls_private_key_path`` optional when running with ``no_tls``.
-
-Application services:
-
-* Application services can now poll on the CS API ``/events`` for their events,
-  by providing their application service ``access_token``.
-* Added exclusive namespace support to application services API.
-
-
-Changes in synapse v0.7.1 (2015-02-19)
-======================================
-
-* Initial alpha implementation of parts of the Application Services API.
-  Including:
-
-  - AS Registration / Unregistration
-  - User Query API
-  - Room Alias Query API
-  - Push transport for receiving events.
-  - User/Alias namespace admin control
-
-* Add cache when fetching events from remote servers to stop repeatedly
-  fetching events with bad signatures.
-* Respect the per remote server retry scheme when fetching both events and
-  server keys to reduce the number of times we send requests to dead servers.
-* Inform remote servers when the local server fails to handle a received event.
-* Turn off python bytecode generation due to problems experienced when
-  upgrading from previous versions.
-
-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)

-
-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
