SECURITY UPDATE: Prevent unauthorised users from setting state events in a room when there is no `m.room.power_levels` event in force in the room. (PR #3397)
Most notable change from v0.30.0 is to switch to the python prometheus library to improve system stats reporting. WARNING: this changes a number of prometheus metrics in a backwards-incompatible manner. For more details, see [docs/metrics-howto.rst](docs/metrics-howto.rst#removal-of-deprecated-metrics--time-based-counters-becoming-histograms-in-0310).
\'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`
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.
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.
- 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.
v0.27.3-rc1 used a stale version of the develop branch so the changelog overstates the functionality. v0.27.3-rc2 is up to date, rc1 should be ignored.
Notable changes include API support for joinability of groups. Also new metrics and phone home stats. Phone home stats include better visibility of system usage so we can tweak synpase to work better for all users rather than our own experience with matrix.org. Also, recording \'r30\' stat which is the measure we use to track 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\"
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.
- Add ability for ASes to override message send time (PR #2754)
- Add support for custom storage providers for media repository (PR #2867, #2777, #2783, #2789, #2791, #2804, #2812, #2814, #2857, #2868, #2767)
- Add purge API features, see [docs/admin\_api/purge\_history\_api.rst](docs/admin_api/purge_history_api.rst) for full details (PR #2858, #2867, #2882, #2946, #2962, #2943)
- Add support for whitelisting 3PIDs that users can register. (PR #2813)
- Add `/room/{id}/event/{id}` API (PR #2766)

Explicitly require authentication when using LDAP3. This is the default on versions of `ldap3` above 1.0, but some distributions will package an older version.
If you are using LDAP3 login and have a version of `ldap3` older than 1.0 it is **CRITICAL to updgrade**.
The release includes major changes to the state storage database schemas, which significantly reduce database size. Synapse will attempt to upgrade the current data in the background. Servers with large SQLite database may experience degradation of performance while this upgrade is in progress, therefore you may want to consider migrating to using Postgres before upgrading very large SQLite databases
- 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.
- 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)
- 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)
- 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)
- 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)
- 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)
- Add `web_client_location` config option to specify static files to be hosted by synapse under `/_matrix/client`. (PR #245)
- Fix bug where we incorrectly populated the `event_forward_extremities` table, resulting in problems joining large remote rooms (e.g. `#matrix:matrix.org`)
- Reduce the number of times we wake up pushers by not listening for presence 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.
- 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.)
- 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)
- 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)

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.

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)
======================================
General:
- Add support for using a PostgreSQL database instead of SQLite. See [docs/postgres.rst](docs/postgres.rst) for details.
- Add password change and reset APIs. See [Registration](https://github.com/matrix-org/matrix-doc/blob/master/specification/10_client_server_api.rst#registration) in the spec.
- Fix memory leak due to not releasing stale notifiers - SYN-339.
- Fix race in caches that occasionally caused some presence updates to be dropped - SYN-369.
- Check server name has not changed on restart.
- Add a sample systemd unit file and a logger configuration in contrib/systemd. Contributed Ivan Shapovalov.
Federation:
- Add key distribution mechanisms for fetching public keys of unavailable remote home servers. See [Retrieving Server Keys](https://github.com/matrix-org/matrix-doc/blob/6f2698/specification/30_server_server_api.rst#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.

- Reliably retry sending of events from Synapse to application services, as per [Application Services](https://github.com/matrix-org/matrix-doc/blob/0c6bd9/specification/25_application_service_api.rst#home-server---application-service-api) 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](docs/application_services.rst) for more information.
Changes in synapse v0.8.1 (2015-03-18)
======================================
- Disable registration by default. New users can be added using the command `register_new_matrix_user` or by enabling registration in the config.

- Fix bug where banning only kicked the user.
Changes in synapse v0.8.0 (2015-03-06)
======================================
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.

- 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)
