-   Add support for new `m.room.canonical_alias` event. (PR #233)
-   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.)
-   Error if a user tries to register with an email already in use. (PR #211)

-   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

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.

Application services:

-   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.
-   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)
======================================

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)

-   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.

Changes in synapse 0.6.1 (2015-01-07)
=====================================

-   Major optimizations to improve performance of initial sync and event sending in large rooms (by up to 10x)
-   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.

-   Fix potential memory leak.

Changes in synapse 0.5.3c (2014-12-02)
======================================

-   Change the default value for the content\_addr option to use the HTTP listener, as by default the HTTPS listener will be using a self-signed certificate.

=====================================

-   Fix bug that caused joining a remote room to fail if a single event was not signed correctly.
-   Fix bug which caused servers to continuously try and fetch events from other servers.

Changes in synapse 0.5.2 (2014-11-26)
=====================================

Changes in synapse 0.3.0 (2014-09-18)
=====================================

See UPGRADE for information about changes to the client server API, including breaking backwards compatibility with VoIP calls and registration API.

Homeserver:

:   -   When a user changes their displayname or avatar the server will now update all their join states to reflect this.
    -   The server now adds \"age\" key to events to indicate how old they are. This is clock independent, so at no point does any server or webclient have to assume their clock is in sync with everyone else.

    -   The \'user\_id\' key has been renamed to \'user\' to better match the login API.
    -   There is an additional login type: \'m.login.email.identity\'.
    -   The command client and web client have been updated to reflect these changes.

Changes in synapse 0.2.3 (2014-09-12)
