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 v0.29.0 (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.

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)

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

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.
