Fix packaging so that schema delta python files get included in the package.

Changes in synapse v0.9.2 (2015-06-12)


  • 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.


  • Add option, gzip_responses, to disable HTTP response compression.


  • Improve resilience of backfill by ensuring we fetch any missing auth events.

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


  • 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

    • --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.

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.
  • Add metrics to synapse. To enable metrics use config options enable_metrics and metrics_port.
  • Fix bug where banning only kicked the user.

Changes in synapse v0.8.0 (2015-03-06)


  • 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.

  • 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.

  • Media repository now includes a Content-Length header on media downloads.
  • Improve quality of thumbnails by changing resizing algorithm.

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 we incorrectly persisted events.

Fix major bug that caused rooms to disappear from peoples initial sync.

Changes in synapse 0.5.1 (2014-11-26)

See UPGRADES.rst for specific instructions on how to upgrade.

  • Fix bug where we served up an Event that did not match its signatures.
  • Fix regression where we no longer correctly handled the case where a homeserver receives an event for a room it doesn't recognise (but is in.)

Changes in synapse 0.3.1 (2014-09-18)

This is a release to hotfix v0.3.0 to fix two regressions.

  • Fix a regression where we sometimes displayed duplicate events.
  • Fix a regression where we didn't immediately remove rooms you were banned in from the recents list.

Changes in synapse 0.3.0 (2014-09-18)
