+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)
+
+Features:
+
+* Cohort analytics (PR #3163, #3241, #3251)
+* Add lxml to docker image for web previews (PR #3239) Thanks to @ptman!
+* Add in flight request metrics (PR #3252)
+
+Changes:
+
+* Remove unused `update_external_syncs` (PR #3233)
+* Use stream rather depth ordering for push actions (PR #3212)
+* Make purge_history operate on tokens (PR #3221)

+
+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.
+
+Features:
+
+* Add a Dockerfile for synapse (PR #2846) Thanks to @kaiyou!
+
+Changes - General:
+
+* nuke-room-from-db.sh: added postgresql option and help (PR #2337) Thanks to @rubo77!
+* Part user from rooms on account deactivate (PR #3201)
+* Make 'unexpected logging context' into warnings (PR #3007)
+* Set Server header in SynapseRequest (PR #3208)
+* remove duplicates from groups tables (PR #3129)
+* Improve exception handling for background processes (PR #3138)
+* Add missing consumeErrors to improve exception handling (PR #3139)
+* reraise exceptions more carefully (PR #3142)
+* Remove redundant call to preserve_fn (PR #3143)
+* Trap exceptions thrown within run_in_background (PR #3144)
+
+Changes - Refactors:
+
+* Refactor /context to reuse pagination storage functions (PR #3193)
+* Refactor recent events func to use pagination func (PR #3195)
+* Refactor pagination DB API to return concrete type (PR #3196)

+* Refactor event storage to prepare for changes in state calculations (PR #3141)
+* Set Server header in SynapseRequest (PR #3208)
+* Use deferred.addTimeout instead of time_bound_deferred (PR #3127, #3178)
+* Use run_in_background in preference to preserve_fn (PR #3140)

+* move httplib import to six (PR #3153) Thanks to @NotAFile!
+* Replace stringIO imports with six (PR #3154, #3168) Thanks to @NotAFile!

+
+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 v0.28.0 (2018-04-26)
+=======================================
+
+Bug Fixes:

+* Fix quarantine media admin API and search reindex (PR #3130)
+* Fix media admin APIs (PR #3134)
+
+
+Changes in synapse v0.28.0-rc1 (2018-04-24)
+===========================================
+
+Minor performance improvement to federation sending and bug fixes.
+
+(Note: This release does not include the delta state resolution implementation discussed in matrix live)
+
+
+Features:
+
+* Add metrics for event processing lag (PR #3090)
+* Add metrics for ResponseCache (PR #3092)

+Changes in synapse v0.27.3-rc2 (2018-04-09)
+==========================================

+overal growth of the Matrix ecosystem. It is defined as:-
+
+Counts the number of native 30 day retained users, defined as:-
+         * Users who have created their accounts more than 30 days
+         * Where last seen at most 30 days ago
+         * Where account creation and last_seen are > 30 days"

+
+
+Changes in synapse v0.27.0-rc1 (2018-03-14)
+===========================================
+
+The common case for running Synapse is not to run separate workers, but for those that do, be aware that synctl no longer starts the main synapse when using ``-a`` option with workers. A new worker file should be added with ``worker_app: synapse.app.homeserver``.
 
 This release also begins the process of renaming a number of the metrics
 reported to prometheus. See `docs/metrics-howto.rst <docs/metrics-howto.rst#block-and-response-metrics-renamed-for-0-27-0>`_.
+Note that the v0.28.0 release will remove the deprecated metric names.
