-DO NOT USE THESE DEMO SERVERS IN PRODUCTION
-
-Requires you to have done:
-    python setup.py develop
-
-
-The demo start.sh will start three synapse servers on ports 8080, 8081 and 8082, with host names localhost:$port. This can be easily changed to `hostname`:$port in start.sh if required.
-
-To enable the servers to communicate untrusted ssl certs are used. In order to do this the servers do not check the certs
-and are configured in a highly insecure way. Do not use these configuration files in production.
-
-stop.sh will stop the synapse servers and the webclient.
-
-clean.sh will delete the databases and log files.
-
-To start a completely new set of servers, run:
-
-    ./demo/stop.sh; ./demo/clean.sh && ./demo/start.sh
-
-
-Logs and sqlitedb will be stored in demo/808{0,1,2}.{log,db}
-
-
-
-Also note that when joining a public room on a different HS via "#foo:bar.net", then you are (in the current impl) joining a room with room_id "foo". This means that it won't work if your HS already has a room with that name.

+**DO NOT USE THESE DEMO SERVERS IN PRODUCTION**
+
+Requires you to have a [Synapse development environment setup](https://matrix-org.github.io/synapse/develop/development/contributing_guide.html#4-install-the-dependencies).
+
+The demo setup allows running three federation Synapse servers, with server
+names `localhost:8080`, `localhost:8081`, and `localhost:8082`.
+
+You can access them via any Matrix client over HTTP at `localhost:8080`,
+`localhost:8081`, and `localhost:8082` or over HTTPS at `localhost:8480`,
+`localhost:8481`, and `localhost:8482`.
+
+To enable the servers to communicate, self-signed SSL certificates are generated
+and the servers are configured in a highly insecure way, including:
+
+* Not checking certificates over federation.
+* Not verifying keys.
+
+The servers are configured to store their data under `demo/8080`, `demo/8081`, and
+`demo/8082`. This includes configuration, logs, SQLite databases, and media.
+
+Note that when joining a public room on a different HS via "#foo:bar.net", then
+you are (in the current impl) joining a room with room_id "foo". This means that
+it won't work if your HS already has a room with that name.
+
+## Using the demo scripts
+
+There's three main scripts with straightforward purposes:
+
+* `start.sh` will start the Synapse servers, generating any missing configuration.
+  * This accepts a single parameter `--no-rate-limit` to "disable" rate limits
+    (they actually still exist, but are very high).
+* `stop.sh` will stop the Synapse servers.
+* `clean.sh` will delete the configuration, databases, log files, etc.
+
+To start a completely new set of servers, run:
+
+```sh
+./demo/stop.sh; ./demo/clean.sh && ./demo/start.sh

+## Outliers
+
+We mark an event as an `outlier` when we haven't figured out the state for the
+room at that point in the DAG yet. They are "floating" events that we haven't
+yet correlated to the DAG.
+
+Outliers typically arise when we fetch the auth chain or state for a given
+event. When that happens, we just grab the events in the state/auth chain,
+without calculating the state at those events, or backfilling their
+`prev_events`. Since we don't have the state at any events fetched in that
+way, we mark them as outliers.
+
+So, typically, we won't have the `prev_events` of an `outlier` in the database,
+(though it's entirely possible that we *might* have them for some other
+reason). Other things that make outliers different from regular events:
+
+ * We don't have state for them, so there should be no entry in
+   `event_to_state_groups` for an outlier. (In practice this isn't always
+   the case, though I'm not sure why: see https://github.com/matrix-org/synapse/issues/12201).
+
+ * We don't record entries for them in the `event_edges`,
+   `event_forward_extremeties` or `event_backward_extremities` tables.
+
+Since outliers are not tied into the DAG, they do not normally form part of the
+timeline sent down to clients via `/sync` or `/messages`; however there is an
+exception:
+
+### Out-of-band membership events
+
+A special case of outlier events are some membership events for federated rooms
+that we aren't full members of. For example:
+
+ * invites received over federation, before we join the room
+ * *rejections* for said invites
+ * knock events for rooms that we would like to join but have not yet joined.
+
+In all the above cases, we don't have the state for the room, which is why they
+are treated as outliers. They are a bit special though, in that they are
+proactively sent to clients via `/sync`.

+# Account data callbacks
+
+Account data callbacks allow module developers to react to changes of the account data
+of local users. Account data callbacks can be registered using the module API's
+`register_account_data_callbacks` method.
+
+## Callbacks
+
+The available account data callbacks are:
+
+### `on_account_data_updated`
+
+_First introduced in Synapse v1.57.0_
+
+```python
+async def on_account_data_updated(
+    user_id: str,
+    room_id: Optional[str],
+    account_data_type: str,
+    content: "synapse.module_api.JsonDict",
+) -> None:
+```
+
+Called after user's account data has been updated. The module is given the
+Matrix ID of the user whose account data is changing, the room ID the data is associated
+with, the type associated with the change, as well as the new content. If the account
+data is not associated with a specific room, then the room ID is `None`.
+
+This callback is triggered when new account data is added or when the data associated with
+a given type (and optionally room) changes. This includes deletion, since in Matrix,
+deleting account data consists of replacing the data associated with a given type
+(and optionally room) with an empty dictionary (`{}`).
+
+Note that this doesn't trigger when changing the tags associated with a room, as these are
+processed separately by Synapse.
+
+If multiple modules implement this callback, Synapse runs them all in order.
+
+## Example
+
+The example below is a module that implements the `on_account_data_updated` callback, and
+sends an event to an audit room when a user changes their account data.

-## Upgrading from legacy structured logging configuration
-
-Versions of Synapse prior to v1.54.0 automatically converted the legacy
-structured logging configuration, which was deprecated in v1.23.0, to the standard
-library logging configuration.
-
-The following reference can be used to update your configuration. Based on the
-drain `type`, we can pick a new handler:
-
-1. For a type of `console`, `console_json`, or `console_json_terse`: a handler
-   with a class of `logging.StreamHandler` and a `stream` of `ext://sys.stdout`
-   or `ext://sys.stderr` should be used.
-2. For a type of `file` or `file_json`: a handler of `logging.FileHandler` with
-   a location of the file path should be used.
-3. For a type of `network_json_terse`: a handler of `synapse.logging.RemoteHandler`
-   with the host and port should be used.
-
-Then based on the drain `type` we can pick a new formatter:
-
-1. For a type of `console` or `file` no formatter is necessary.
-2. For a type of `console_json` or `file_json`: a formatter of
-   `synapse.logging.JsonFormatter` should be used.
-3. For a type of `console_json_terse` or `network_json_terse`: a formatter of
-   `synapse.logging.TerseJsonFormatter` should be used.
-
-For each new handler and formatter they should be added to the logging configuration
-and then assigned to either a logger or the root logger.
-
-An example legacy configuration:
-
-```yaml
-structured: true
-
-loggers:
-    synapse:
-        level: INFO
-    synapse.storage.SQL:
-        level: WARNING

-        location: stdout
-    file:
-        type: file_json
-        location: homeserver.log
-```
-
-Would be converted into a new configuration:
-
-```yaml
-version: 1
-
-formatters:
-    json:
-        class: synapse.logging.JsonFormatter
-
-handlers:
-    console:
-        class: logging.StreamHandler
-        stream: ext://sys.stdout

-        level: INFO
-        handlers: [console, file]
-    synapse.storage.SQL:

-sending plain logs over the network, or using different handlers for different

+# Upgrading to v1.57.0
+
+## Changes to database schema for application services
+
+Synapse v1.57.0 includes a [change](https://github.com/matrix-org/synapse/pull/12209) to the
+way transaction IDs are managed for application services. If your deployment uses a dedicated
+worker for application service traffic, **it must be stopped** when the database is upgraded
+(which normally happens when the main process is upgraded), to ensure the change is made safely
+without any risk of reusing transaction IDs.
+
+Deployments which do not use separate worker processes can be upgraded as normal. Similarly,
+deployments where no application services are in use can be upgraded as normal.
+
+<details>
+<summary><b>Recovering from an incorrect upgrade</b></summary>
+
+If the database schema is upgraded *without* stopping the worker responsible
+for AS traffic, then the following error may be given when attempting to start
+a Synapse worker or master process:
+
+```
+**********************************************************************************
+ Error during initialisation:
+
+ Postgres sequence 'application_services_txn_id_seq' is inconsistent with associated
+ table 'application_services_txns'. This can happen if Synapse has been downgraded and
+ then upgraded again, or due to a bad migration.
+
+ To fix this error, shut down Synapse (including any and all workers)
+ and run the following SQL:
+
+     SELECT setval('application_services_txn_id_seq', (
+         SELECT GREATEST(MAX(txn_id), 0) FROM application_services_txns
+     ));
+
+ See docs/postgres.md for more information.
+
+ There may be more information in the logs.
+**********************************************************************************
+```
+
+This error may also be seen if Synapse is *downgraded* to an earlier version,
+and then upgraded again to v1.57.0 or later.
+
+In either case:
+
+ 1. Ensure that the worker responsible for AS traffic is stopped.
+ 2. Run the SQL command given in the error message via `psql`.
+
+Synapse should then start correctly.
+</details>
+
+# Upgrading to v1.56.0
+
+## Open registration without verification is now disabled by default
+
+Synapse will refuse to start if registration is enabled without email, captcha, or token-based verification unless the new config
+flag `enable_registration_without_verification` is set to "true".
+
+## Groups/communities feature has been deprecated
+
+The non-standard groups/communities feature in Synapse has been deprecated and will
+be disabled by default in Synapse v1.58.0.
+
+You can test disabling it by adding the following to your homeserver configuration:
+
+```yaml
+experimental_features:
+  groups_enabled: false
+```
+
+## Change in behaviour for PostgreSQL databases with unsafe locale
+
+Synapse now refuses to start when using PostgreSQL with non-`C` values for `COLLATE` and
+`CTYPE` unless the config flag `allow_unsafe_locale`, found in the database section of
+the configuration file, is set to `true`. See the [PostgreSQL documentation](https://matrix-org.github.io/synapse/latest/postgres.html#fixing-incorrect-collate-or-ctype)
+for more information and instructions on how to fix a database with incorrect values.
+
+# Upgrading to v1.55.0
+
+## `synctl` script has been moved
+
+The `synctl` script
+[has been made](https://github.com/matrix-org/synapse/pull/12140) an
+[entry point](https://packaging.python.org/en/latest/specifications/entry-points/)
+and no longer exists at the root of Synapse's source tree. If you wish to use
+`synctl` to manage your homeserver, you should invoke `synctl` directly, e.g.
+`synctl start` instead of `./synctl start` or `/path/to/synctl start`.
+
+You will need to ensure `synctl` is on your `PATH`.
+  - This is automatically the case when using
+    [Debian packages](https://packages.matrix.org/debian/) or
+    [docker images](https://hub.docker.com/r/matrixdotorg/synapse)
+    provided by Matrix.org.
+  - When installing from a wheel, sdist, or PyPI, a `synctl` executable is added
+    to your Python installation's `bin`. This should be on your `PATH`
+    automatically, though you might need to activate a virtual environment
+    depending on how you installed Synapse.
