+Synapse 1.69.0 (2022-10-17)
+===========================
+
+Please note that legacy Prometheus metric names are now deprecated and will be removed in Synapse 1.73.0.
+Server administrators should update their dashboards and alerting rules to avoid using the deprecated metric names.
+See the [upgrade notes](https://matrix-org.github.io/synapse/v1.69/upgrade.html#upgrading-to-v1690) for more details.
+
+
+No significant changes since 1.69.0rc4.
+
+
+Synapse 1.69.0rc4 (2022-10-14)
+==============================
+
+Bugfixes
+--------
+
+- Fix poor performance of the `event_push_backfill_thread_id` background update, which was introduced in Synapse 1.68.0rc1. ([\#14172](https://github.com/matrix-org/synapse/issues/14172), [\#14181](https://github.com/matrix-org/synapse/issues/14181))
+
+
+Updates to the Docker image
+---------------------------
+
+- Fix docker build OOMing in CI for arm64 builds. ([\#14173](https://github.com/matrix-org/synapse/issues/14173))
+
+
+Synapse 1.69.0rc3 (2022-10-12)
+==============================
+
+Bugfixes
+--------
+
+- Fix an issue with Docker images causing the Rust dependencies to not be pinned correctly. Introduced in v1.68.0 ([\#14129](https://github.com/matrix-org/synapse/issues/14129))
+- Fix a bug introduced in Synapse 1.69.0rc1 which would cause registration replication requests to fail if the worker sending the request is not running Synapse 1.69. ([\#14135](https://github.com/matrix-org/synapse/issues/14135))
+- Fix error in background update when rotating existing notifications. Introduced in v1.69.0rc2. ([\#14138](https://github.com/matrix-org/synapse/issues/14138))
+
+
+Internal Changes
+----------------
+
+- Rename the `url_preview` extra to `url-preview`, for compatability with poetry-core 1.3.0 and [PEP 685](https://peps.python.org/pep-0685/). From-source installations using this extra will need to install using the new name. ([\#14085](https://github.com/matrix-org/synapse/issues/14085))
+
+
+Synapse 1.69.0rc2 (2022-10-06)
+==============================
+
+Deprecations and Removals
+-------------------------
+
+- Deprecate the `generate_short_term_login_token` method in favor of an async `create_login_token` method in the Module API. ([\#13842](https://github.com/matrix-org/synapse/issues/13842))
+
+
+Internal Changes
+----------------
+
+- Ensure Synapse v1.69 works with upcoming database changes in v1.70. ([\#14045](https://github.com/matrix-org/synapse/issues/14045))
+- Fix a bug introduced in Synapse v1.68.0 where messages could not be sent in rooms with non-integer `notifications` power level. ([\#14073](https://github.com/matrix-org/synapse/issues/14073))
+- Temporarily pin build-system requirements to workaround an incompatibility with poetry-core 1.3.0. This will be reverted before the v1.69.0 release proper, see [\#14079](https://github.com/matrix-org/synapse/issues/14079). ([\#14080](https://github.com/matrix-org/synapse/issues/14080))
+
+
+Synapse 1.69.0rc1 (2022-10-04)
+==============================
+
+Features
+--------
+
+- Allow application services to set the `origin_server_ts` of a state event by providing the query parameter `ts` in [`PUT /_matrix/client/r0/rooms/{roomId}/state/{eventType}/{stateKey}`](https://spec.matrix.org/v1.4/client-server-api/#put_matrixclientv3roomsroomidstateeventtypestatekey), per [MSC3316](https://github.com/matrix-org/matrix-doc/pull/3316). Contributed by @lukasdenk. ([\#11866](https://github.com/matrix-org/synapse/issues/11866))
+- Allow server admins to require a manual approval process before new accounts can be used (using [MSC3866](https://github.com/matrix-org/matrix-spec-proposals/pull/3866)). ([\#13556](https://github.com/matrix-org/synapse/issues/13556))
+- Exponentially backoff from backfilling the same event over and over. ([\#13635](https://github.com/matrix-org/synapse/issues/13635), [\#13936](https://github.com/matrix-org/synapse/issues/13936))
+- Add cache invalidation across workers to module API. ([\#13667](https://github.com/matrix-org/synapse/issues/13667), [\#13947](https://github.com/matrix-org/synapse/issues/13947))
+- Experimental implementation of [MSC3882](https://github.com/matrix-org/matrix-spec-proposals/pull/3882) to allow an existing device/session to generate a login token for use on a new device/session. ([\#13722](https://github.com/matrix-org/synapse/issues/13722), [\#13868](https://github.com/matrix-org/synapse/issues/13868))
+- Experimental support for thread-specific receipts ([MSC3771](https://github.com/matrix-org/matrix-spec-proposals/pull/3771)). ([\#13782](https://github.com/matrix-org/synapse/issues/13782), [\#13893](https://github.com/matrix-org/synapse/issues/13893), [\#13932](https://github.com/matrix-org/synapse/issues/13932), [\#13937](https://github.com/matrix-org/synapse/issues/13937), [\#13939](https://github.com/matrix-org/synapse/issues/13939))
+- Add experimental support for [MSC3881: Remotely toggle push notifications for another client](https://github.com/matrix-org/matrix-spec-proposals/pull/3881). ([\#13799](https://github.com/matrix-org/synapse/issues/13799), [\#13831](https://github.com/matrix-org/synapse/issues/13831), [\#13860](https://github.com/matrix-org/synapse/issues/13860))
+- Keep track when an event pulled over federation fails its signature check so we can intelligently back-off in the future. ([\#13815](https://github.com/matrix-org/synapse/issues/13815))

+Synapse 1.67.0 (2022-09-13)
+===========================
+
+This release removes using the deprecated direct TCP replication configuration
+for workers. Server admins should use Redis instead. See the [upgrade
+notes](https://matrix-org.github.io/synapse/v1.67/upgrade.html#upgrading-to-v1670).
+
+The minimum version of `poetry` supported for managing source checkouts is now
+1.2.0.
+
+**Notice:** from the next major release (1.68.0) installing Synapse from a source
+checkout will require a recent Rust compiler. Those using packages or
+`pip install matrix-synapse` will not be affected. See the [upgrade
+notes](https://matrix-org.github.io/synapse/v1.67/upgrade.html#upgrading-to-v1670).
+
+**Notice:** from the next major release (1.68.0), running Synapse with a SQLite
+database will require SQLite version 3.27.0 or higher. (The [current minimum
+ version is SQLite 3.22.0](https://github.com/matrix-org/synapse/blob/release-v1.67/synapse/storage/engines/sqlite.py#L69-L78).)
+See [#12983](https://github.com/matrix-org/synapse/issues/12983) and the [upgrade notes](https://matrix-org.github.io/synapse/v1.67/upgrade.html#upgrading-to-v1670) for more details.

+
+Synapse 1.66.0 (2022-08-31)
+===========================
+
+No significant changes since 1.66.0rc2.
+
+This release removes the ability for homeservers to delegate email ownership
+verification and password reset confirmation to identity servers. This removal
+was originally planned for Synapse 1.64, but was later deferred until now. See
+the [upgrade notes](https://matrix-org.github.io/synapse/v1.66/upgrade.html#upgrading-to-v1660) for more details.
+
+Deployments with multiple workers should note that the direct TCP replication
+configuration was deprecated in Synapse 1.18.0 and will be removed in Synapse
+v1.67.0. In particular, the TCP `replication` [listener](https://matrix-org.github.io/synapse/v1.66/usage/configuration/config_documentation.html#listeners)
+type (not to be confused with the `replication` resource on the `http` listener
+type) and the `worker_replication_port` config option will be removed .
+
+To migrate to Redis, add the [`redis` config](https://matrix-org.github.io/synapse/v1.66/workers.html#shared-configuration),
+then remove the TCP `replication` listener from config of the master and
+`worker_replication_port` from worker config. Note that a HTTP listener with a
+`replication` resource is still required. See the
+[worker documentation](https://matrix-org.github.io/synapse/v1.66/workers.html)
+for more details.

+## Security advisory
+
+The following issue is fixed in 1.62.0.
+
+* [GHSA-jhjh-776m-4765](https://github.com/matrix-org/synapse/security/advisories/GHSA-jhjh-776m-4765) / [CVE-2022-31152](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2022-31152)
+
+  Synapse instances prior to 1.62.0 did not implement the Matrix [event authorization rules](https://spec.matrix.org/v1.3/rooms/v10/#authorization-rules) correctly. An attacker could craft events which would be accepted by Synapse but not a spec-conformant server, potentially causing divergence in the room state between servers.
+
+  Homeservers with federation disabled via the [`federation_domain_whitelist`](https://matrix-org.github.io/synapse/latest/usage/configuration/config_documentation.html#federation_domain_whitelist) config option are unaffected.
+
+  Administrators of homeservers with federation enabled are advised to upgrade to v1.62.0 or higher.
+
+  Fixed by [#13087](https://github.com/matrix-org/synapse/pull/13087) and [#13088](https://github.com/matrix-org/synapse/pull/13088).

 Synapse |support| |development| |documentation| |license| |pypi| |python|
 =========================================================================
 
+Synapse is an open-source `Matrix <https://matrix.org/>`_ homeserver written and
+maintained by the Matrix.org Foundation. We began rapid development in 2014,
+reaching v1.0.0 in 2019. Development on Synapse and the Matrix protocol itself continues
+in earnest today.
+
+Briefly, Matrix is an open standard for communications on the internet, supporting
+federation, encryption and VoIP. Matrix.org has more to say about the `goals of the
+Matrix project <https://matrix.org/docs/guides/introduction>`_, and the `formal specification
+<https://spec.matrix.org/>`_ describes the technical details.
+
 .. contents::
 
-Introduction
-============
+Installing and configuration
+============================
 
-Matrix is an ambitious new ecosystem for open federated Instant Messaging and
-VoIP.  The basics you need to know to get up and running are:
-
-- Everything in Matrix happens in a room.  Rooms are distributed and do not
-  exist on any single server.  Rooms can be located using convenience aliases
-  like ``#matrix:matrix.org`` or ``#test:localhost:8448``.
-
-- Matrix user IDs look like ``@matthew:matrix.org`` (although in the future
-  you will normally refer to yourself and others using a third party identifier
-  (3PID): email address, phone number, etc rather than manipulating Matrix user IDs)
-
-The overall architecture is::
-
-      client <----> homeserver <=====================> homeserver <----> client
-             https://somewhere.org/_matrix      https://elsewhere.net/_matrix
-
-``#matrix:matrix.org`` is the official support room for Matrix, and can be
-accessed by any client from https://matrix.org/docs/projects/try-matrix-now.html or
-via IRC bridge at irc://irc.libera.chat/matrix.
-
-Synapse is currently in rapid development, but as of version 0.5 we believe it
-is sufficiently stable to be run as an internet-facing service for real usage!
-
-About Matrix
-============
-
-Matrix specifies a set of pragmatic RESTful HTTP JSON APIs as an open standard,
-which handle:
-
-- Creating and managing fully distributed chat rooms with no
-  single points of control or failure
-- Eventually-consistent cryptographically secure synchronisation of room
-  state across a global open network of federated servers and services
-- Sending and receiving extensible messages in a room with (optional)
-  end-to-end encryption
-- Inviting, joining, leaving, kicking, banning room members
-- Managing user accounts (registration, login, logout)
-- Using 3rd Party IDs (3PIDs) such as email addresses, phone numbers,
-  Facebook accounts to authenticate, identify and discover users on Matrix.
-- Placing 1:1 VoIP and Video calls
-
-These APIs are intended to be implemented on a wide range of servers, services
-and clients, letting developers build messaging and VoIP functionality on top
-of the entirely open Matrix ecosystem rather than using closed or proprietary
-solutions. The hope is for Matrix to act as the building blocks for a new
-generation of fully open and interoperable messaging and VoIP apps for the
-internet.
-
-Synapse is a Matrix "homeserver" implementation developed by the matrix.org core
-team, written in Python 3/Twisted.
-
-In Matrix, every user runs one or more Matrix clients, which connect through to
-a Matrix homeserver. The homeserver stores all their personal chat history and
-user account information - much as a mail client connects through to an
-IMAP/SMTP server. Just like email, you can either run your own Matrix
-homeserver and control and own your own communications and history or use one
-hosted by someone else (e.g. matrix.org) - there is no single point of control
-or mandatory service provider in Matrix, unlike WhatsApp, Facebook, Hangouts,
-etc.
-
-We'd like to invite you to join #matrix:matrix.org (via
-https://matrix.org/docs/projects/try-matrix-now.html), run a homeserver, take a look
-at the `Matrix spec <https://matrix.org/docs/spec>`_, and experiment with the
-`APIs <https://matrix.org/docs/api>`_ and `Client SDKs
-<https://matrix.org/docs/projects/try-matrix-now.html#client-sdks>`_.
-
-Thanks for using Matrix!

-For support installing or managing Synapse, please join |room|_ (from a matrix.org
-account if necessary) and ask questions there. We do not use GitHub issues for
-support requests, only for bug reports and feature requests.

-Synapse Installation
-====================
+The Synapse documentation describes `how to install Synapse <https://matrix-org.github.io/synapse/latest/setup/installation.html>`_. We recommend using
+`Docker images <https://matrix-org.github.io/synapse/latest/setup/installation.html#docker-images-and-ansible-playbooks>`_ or `Debian packages from Matrix.org
+<https://matrix-org.github.io/synapse/latest/setup/installation.html#matrixorg-packages>`_.
 
 .. _federation:
 
-* For details on how to install synapse, see
-  `Installation Instructions <https://matrix-org.github.io/synapse/latest/setup/installation.html>`_.
-* For specific details on how to configure Synapse for federation see `docs/federate.md <docs/federate.md>`_
+Synapse has a variety of `config options
+<https://matrix-org.github.io/synapse/latest/usage/configuration/config_documentation.html>`_
+which can be used to customise its behaviour after installation.
+There are additional details on how to `configure Synapse for federation here
+<https://matrix-org.github.io/synapse/latest/federate.html>`_.
+
+.. _reverse-proxy:
+
+Using a reverse proxy with Synapse
+----------------------------------
+
+It is recommended to put a reverse proxy such as
+`nginx <https://nginx.org/en/docs/http/ngx_http_proxy_module.html>`_,
+`Apache <https://httpd.apache.org/docs/current/mod/mod_proxy_http.html>`_,
+`Caddy <https://caddyserver.com/docs/quick-starts/reverse-proxy>`_,
+`HAProxy <https://www.haproxy.org/>`_ or
+`relayd <https://man.openbsd.org/relayd.8>`_ in front of Synapse. One advantage of
+doing so is that it means that you can expose the default https port (443) to
+Matrix clients without needing to run Synapse with root privileges.
+For information on configuring one, see `the reverse proxy docs
+<https://matrix-org.github.io/synapse/latest/reverse_proxy.html>`_.
+
+Upgrading an existing Synapse
+-----------------------------
+
+The instructions for upgrading Synapse are in `the upgrade notes`_.
+Please check these instructions as upgrading may require extra steps for some
+versions of Synapse.
+
+.. _the upgrade notes: https://matrix-org.github.io/synapse/develop/upgrade.html
 
 
-Connecting to Synapse from a client
-===================================
+Platform dependencies
+---------------------
 
-The easiest way to try out your new Synapse installation is by connecting to it
-from a web client.
+Synapse uses a number of platform dependencies such as Python and PostgreSQL,
+and aims to follow supported upstream versions. See the
+`deprecation policy <https://matrix-org.github.io/synapse/latest/deprecation_policy.html>`_
+for more details.
 
-Unless you are running a test instance of Synapse on your local machine, in
-general, you will need to enable TLS support before you can successfully
-connect from a client: see
-`TLS certificates <https://matrix-org.github.io/synapse/latest/setup/installation.html#tls-certificates>`_.
-
-An easy way to get started is to login or register via Element at
-https://app.element.io/#/login or https://app.element.io/#/register respectively.
-You will need to change the server you are logging into from ``matrix.org``
-and instead specify a Homeserver URL of ``https://<server_name>:8448``
-(or just ``https://<server_name>`` if you are using a reverse proxy).
-If you prefer to use another client, refer to our
-`client breakdown <https://matrix.org/docs/projects/clients-matrix>`_.
-
-If all goes well you should at least be able to log in, create a room, and
-start sending messages.
-
-.. _`client-user-reg`:
-
-Registering a new user from a client
-------------------------------------
-
-By default, registration of new users via Matrix clients is disabled. To enable
-it, specify ``enable_registration: true`` in ``homeserver.yaml``. (It is then
-recommended to also set up CAPTCHA - see `<docs/CAPTCHA_SETUP.md>`_.)
-
-Once ``enable_registration`` is set to ``true``, it is possible to register a
-user via a Matrix client.
-
-Your new user name will be formed partly from the ``server_name``, and partly
-from a localpart you specify when you create the account. Your name will take
-the form of::
-
-    @localpart:my.domain.name
-
-(pronounced "at localpart on my dot domain dot name").
-
-As when logging in, you will need to specify a "Custom server".  Specify your
-desired ``localpart`` in the 'User name' box.

+By default, registration of new users via Matrix clients is disabled. To enable
+it:
+
+1. In the
+   `registration config section <https://matrix-org.github.io/synapse/latest/usage/configuration/config_documentation.html#registration>`_
+   set ``enable_registration: true`` in ``homeserver.yaml``.

+
+   a. set up a `CAPTCHA <https://matrix-org.github.io/synapse/latest/CAPTCHA_SETUP.html>`_, or
+   b. set ``enable_registration_without_verification: true`` in ``homeserver.yaml``.
+
+We **strongly** recommend using a CAPTCHA, particularly if your homeserver is exposed to
+the public internet. Without it, anyone can freely register accounts on your homeserver.
+This can be exploited by attackers to create spambots targetting the rest of the Matrix
+federation.
+
+Your new user name will be formed partly from the ``server_name``, and partly

 `#synapse-dev:matrix.org <https://matrix.to/#/#synapse-dev:matrix.org>`_, featuring real humans!
 
 
-Quick start
------------
-
-Before setting up a development environment for synapse, make sure you have the
-system dependencies (such as the python header files) installed - see
-`Platform-specific prerequisites <https://matrix-org.github.io/synapse/latest/setup/installation.html#platform-specific-prerequisites>`_.
-
-To check out a synapse for development, clone the git repo into a working
-directory of your choice::
-
-    git clone https://github.com/matrix-org/synapse.git
-    cd synapse
-
-Synapse has a number of external dependencies. We maintain a fixed development
-environment using `Poetry <https://python-poetry.org/>`_. First, install poetry. We recommend::
-
-    pip install --user pipx
-    pipx install poetry
-
-as described `here <https://python-poetry.org/docs/#installing-with-pipx>`_.
-(See `poetry's installation docs <https://python-poetry.org/docs/#installation>`_
-for other installation methods.) Then ask poetry to create a virtual environment
-from the project and install Synapse's dependencies::
-
-    poetry install --extras "all test"
-
-This will run a process of downloading and installing all the needed
-dependencies into a virtual env.
-
-We recommend using the demo which starts 3 federated instances running on ports `8080` - `8082`::
-
-    poetry run ./demo/start.sh
-
-(to stop, you can use ``poetry run ./demo/stop.sh``)
-
-See the `demo documentation <https://matrix-org.github.io/synapse/develop/development/demo.html>`_
-for more information.
-
-If you just want to start a single instance of the app and run it directly::
-
-    # Create the homeserver.yaml config once
-    poetry run synapse_homeserver \
-      --server-name my.domain.name \
-      --config-path homeserver.yaml \
-      --generate-config \
-      --report-stats=[yes|no]
-
-    # Start the app
-    poetry run synapse_homeserver --config-path homeserver.yaml
-
-
-Running the unit tests
-----------------------
-
-After getting up and running, you may wish to run Synapse's unit tests to
-check that everything is installed correctly::
-
-    poetry run trial tests
-
-This should end with a 'PASSED' result (note that exact numbers will
-differ)::
-
-    Ran 1337 tests in 716.064s
-
-    PASSED (skips=15, successes=1322)
-
-For more tips on running the unit tests, like running a specific test or
-to see the logging output, see the `CONTRIBUTING doc <CONTRIBUTING.md#run-the-unit-tests>`_.
-
-
-Running the Integration Tests
------------------------------
-
-Synapse is accompanied by `SyTest <https://github.com/matrix-org/sytest>`_,
-a Matrix homeserver integration testing suite, which uses HTTP requests to
-access the API as a Matrix client would. It is able to run Synapse directly from
-the source tree, so installation of the server is not required.

-Testing with SyTest is recommended for verifying that changes related to the
-Client-Server API are functioning correctly. See the `SyTest installation
-instructions <https://github.com/matrix-org/sytest#installing>`_ for details.
-
-
-Platform dependencies
-=====================
-
-Synapse uses a number of platform dependencies such as Python and PostgreSQL,
-and aims to follow supported upstream versions. See the
-`<docs/deprecation_policy.md>`_ document for more details.

-
-Running out of File Handles
----------------------------
-
-If synapse runs out of file handles, it typically fails badly - live-locking
-at 100% CPU, and/or failing to accept new TCP connections (blocking the
-connecting client).  Matrix currently can legitimately use a lot of file handles,
-thanks to busy rooms like #matrix:matrix.org containing hundreds of participating
-servers.  The first time a server talks in a room it will try to connect
-simultaneously to all participating servers, which could exhaust the available
-file descriptors between DNS queries & HTTPS sockets, especially if DNS is slow
-to respond. (We need to improve the routing algorithm used to be better than
-full mesh, but as of March 2019 this hasn't happened yet).
-
-If you hit this failure mode, we recommend increasing the maximum number of
-open file handles to be at least 4096 (assuming a default of 1024 or 256).
-This is typically done by editing ``/etc/security/limits.conf``
-
-Separately, Synapse may leak file handles if inbound HTTP requests get stuck
-during processing - e.g. blocked behind a lock or talking to a remote server etc.
-This is best diagnosed by matching up the 'Received request' and 'Processed request'
-log lines and looking for any 'Processed request' lines which take more than
-a few seconds to execute. Please let us know at #synapse:matrix.org if
-you see this failure mode so we can help debug it, however.
-
-Help!! Synapse is slow and eats all my RAM/CPU!
------------------------------------------------
-
-First, ensure you are running the latest version of Synapse, using Python 3
-with a PostgreSQL database.
-
-Synapse's architecture is quite RAM hungry currently - we deliberately
-cache a lot of recent room data and metadata in RAM in order to speed up
-common requests. We'll improve this in the future, but for now the easiest
-way to either reduce the RAM usage (at the risk of slowing things down)
-is to set the almost-undocumented ``SYNAPSE_CACHE_FACTOR`` environment
-variable. The default is 0.5, which can be decreased to reduce RAM usage
-in memory constrained enviroments, or increased if performance starts to
-degrade.
-
-However, degraded performance due to a low cache factor, common on
-machines with slow disks, often leads to explosions in memory use due
-backlogged requests. In this case, reducing the cache factor will make
-things worse. Instead, try increasing it drastically. 2.0 is a good
-starting value.
-
-Using `libjemalloc <http://jemalloc.net/>`_ can also yield a significant
-improvement in overall memory use, and especially in terms of giving back
-RAM to the OS. To use it, the library must simply be put in the
-LD_PRELOAD environment variable when launching Synapse. On Debian, this
-can be done by installing the ``libjemalloc1`` package and adding this
-line to ``/etc/default/matrix-synapse``::
-
-    LD_PRELOAD=/usr/lib/x86_64-linux-gnu/libjemalloc.so.1
-
-This can make a significant difference on Python 2.7 - it's unclear how
-much of an improvement it provides on Python 3.x.
-
-If you're encountering high CPU use by the Synapse process itself, you
-may be affected by a bug with presence tracking that leads to a
-massive excess of outgoing federation requests (see `discussion
-<https://github.com/matrix-org/synapse/issues/3971>`_). If metrics
-indicate that your server is also issuing far more outgoing federation
-requests than can be accounted for by your users' activity, this is a
-likely cause. The misbehavior can be worked around by setting
-the following in the Synapse config file:
-
-.. code-block:: yaml
-
-   presence:
-       enabled: false
-
-People can't accept room invitations from me
---------------------------------------------
-
-The typical failure mode here is that you send an invitation to someone
-to join a room or direct chat, but when they go to accept it, they get an
-error (typically along the lines of "Invalid signature"). They might see
-something like the following in their logs::
-
-    2019-09-11 19:32:04,271 - synapse.federation.transport.server - 288 - WARNING - GET-11752 - authenticate_request failed: 401: Invalid signature for server <server> with key ed25519:a_EqML: Unable to verify signature for <server>
-
-This is normally caused by a misconfiguration in your reverse-proxy. See
-`<docs/reverse_proxy.md>`_ and double-check that your settings are correct.

+# Room Messages API
+
+The Room Messages admin API allows server admins to get all messages
+sent to a room in a given timeframe. There are various parameters available
+that allow for filtering and ordering the returned list. This API supports pagination.
+
+To use it, you will need to authenticate by providing an `access_token`
+for a server admin: see [Admin API](../usage/administration/admin_api).
+
+This endpoint mirrors the [Matrix Spec defined Messages API](https://spec.matrix.org/v1.1/client-server-api/#get_matrixclientv3roomsroomidmessages).
+
+The API is:
+```
+GET /_synapse/admin/v1/rooms/<room_id>/messages
+```
+
+**Parameters**
+
+The following path parameters are required:
+
+* `room_id` - The ID of the room you wish you fetch messages from.
+
+The following query parameters are available:
+
+* `from` (required) - The token to start returning events from. This token can be obtained from a prev_batch
+  or next_batch token returned by the /sync endpoint, or from an end token returned by a previous request to this endpoint.
+* `to` - The token to spot returning events at.
+* `limit` - The maximum number of events to return. Defaults to `10`.
+* `filter` - A JSON RoomEventFilter to filter returned events with.
+* `dir` - The direction to return events from. Either `f` for forwards or `b` for backwards. Setting
+  this value to `b` will reverse the above sort order. Defaults to `f`.
+
+**Response**
+
+The following fields are possible in the JSON response body:
+
+* `chunk` - A list of room events. The order depends on the dir parameter.
+          Note that an empty chunk does not necessarily imply that no more events are available. Clients should continue to paginate until no end property is returned.
+* `end` - A token corresponding to the end of chunk. This token can be passed back to this endpoint to request further events.
+          If no further events are available, this property is omitted from the response.
+* `start` - A token corresponding to the start of chunk.
+* `state` - A list of state events relevant to showing the chunk.
+
+**Example**

 ## Chain Cover Index
 
 Synapse computes auth chain differences by pre-computing a "chain cover" index

-event A in the auth chain of event B". This is done by assigning every event a
-*chain ID* and *sequence number* (e.g. `(5,3)`), and having a map of *links*
-between chains (e.g. `(5,3) -> (2,4)`) such that A is reachable by B (i.e. `A`

+like "is event `A` in the auth chain of event `B`?". We could do this with an index
+that tracks all pairs `(A, B)` such that `A` is in the auth chain of `B`. However, this
+would be prohibitively large, scaling poorly as the room accumulates more state
+events.
 
-1. A and B have the same chain ID and `A`'s sequence number is less than `B`'s
+Instead, we break down the graph into *chains*. A chain is a subset of a DAG
+with the following property: for any pair of events `E` and `F` in the chain,
+the chain contains a path `E -> F` or a path `F -> E`. This forces a chain to be
+linear (without forks), e.g. `E -> F -> G -> ... -> H`. Each event in the chain
+is given a *sequence number* local to that chain. The oldest event `E` in the
+chain has sequence number 1. If `E` has a child `F` in the chain, then `F` has
+sequence number 2. If `E` has a grandchild `G` in the chain, then `G` has
+sequence number 3; and so on.
+
+Synapse ensures that each persisted event belongs to exactly one chain, and
+tracks how the chains are connected to one another. This allows us to
+efficiently answer reachability queries. Doing so uses less storage than
+tracking reachability on an event-by-event basis, particularly when we have
+fewer and longer chains. See

+makes it very easy to find and clean up everything in a room when it needs to be
+purged (no need to use sub-`select` query or join from the `events` table).
+
+A note on collisions: In room versions `1` and `2` it's possible to end up with
+two events with the same `event_id` (in the same or different rooms). After room
+version `3`, that can only happen with a hash collision, which we basically hope
+will never happen (SHA256 has a massive big key space).

+## Changes to the receipts replication streams
+
+Synapse now includes information indicating if a receipt applies to a thread when

+change: v1.68 and workers cannot process receipts replicated by v1.69 workers, and

+replication will resume as normal.
+
+
+## Deprecation of legacy Prometheus metric names
+
+In current versions of Synapse, some Prometheus metrics are emitted under two different names,
+with one of the names being older but non-compliant with OpenMetrics and Prometheus conventions
+and one of the names being newer but compliant.
+
+Synapse v1.71.0 will turn the old metric names off *by default*.
+For administrators that still rely on them and have not had chance to update their
+uses of the metrics, it's possible to specify `enable_legacy_metrics: true` in
+the configuration to re-enable them temporarily.
+
+Synapse v1.73.0 will **remove legacy metric names altogether** and it will no longer
+be possible to re-enable them.
+
+The Grafana dashboard, Prometheus recording rules and Prometheus Consoles included
+in the `contrib` directory in the Synapse repository have been updated to no longer
+rely on the legacy names. These can be used on a current version of Synapse
+because current versions of Synapse emit both old and new names.
+
+You may need to update your alerting rules or any other rules that depend on
+the names of Prometheus metrics.
+If you want to test your changes before legacy names are disabled by default,
+you may specify `enable_legacy_metrics: false` in your homeserver configuration.
+
+A list of affected metrics is available on the [Metrics How-to page](https://matrix-org.github.io/synapse/v1.69/metrics-howto.html?highlight=metrics%20deprecated#renaming-of-metrics--deprecation-of-old-names-in-12).

+## Deprecation of the `generate_short_term_login_token` module API method

+```python
+def generate_short_term_login_token(
+    self,
+    user_id: str,
+    duration_in_ms: int = (2 * 60 * 1000),
+    auth_provider_id: str = "",
+    auth_provider_session_id: Optional[str] = None,
+) -> str:
+    ...
+```
+
+It has been replaced by an asynchronous equivalent:
+
+```python
+async def create_login_token(
+    self,
+    user_id: str,
+    duration_in_ms: int = (2 * 60 * 1000),

+    auth_provider_session_id: Optional[str] = None,
+) -> str:
+    ...
+```
+

+# Upgrading to v1.67.0
+
+## Direct TCP replication is no longer supported: migrate to Redis
+
+Redis support was added in v1.13.0 with it becoming the recommended method in
+v1.18.0. It replaced the old direct TCP connections (which was deprecated as of
+v1.18.0) to the main process. With Redis, rather than all the workers connecting
+to the main process, all the workers and the main process connect to Redis,
+which relays replication commands between processes. This can give a significant
+CPU saving on the main process and is a prerequisite for upcoming
+performance improvements.
+
+To migrate to Redis add the [`redis` config](./workers.md#shared-configuration),
+and remove the TCP `replication` listener from config of the master and
+`worker_replication_port` from worker config. Note that a HTTP listener with a
+`replication` resource is still required.
+
+## Minimum version of Poetry is now v1.2.0
+
+The minimum supported version of poetry is now 1.2. This should only affect
+those installing from a source checkout.
+
+## Rust requirement in the next release
+
+From the next major release (v1.68.0) installing Synapse from a source checkout
+will require a recent Rust compiler. Those using packages or
+`pip install matrix-synapse` will not be affected.
+
+The simplest way of installing Rust is via [rustup.rs](https://rustup.rs/)
+
+## SQLite version requirement in the next release
+
+From the next major release (v1.68.0) Synapse will require SQLite 3.27.0 or
+higher. Synapse v1.67.0 will be the last major release supporting SQLite
+versions 3.22 to 3.26.
+
+Those using Docker images or Debian packages from Matrix.org will not be
+affected. If you have installed from source, you should check the version of
+SQLite used by Python with:
+
+```shell
+python -c "import sqlite3; print(sqlite3.sqlite_version)"
+```
+
+If this is too old, refer to your distribution for advice on upgrading.
+
+
+# Upgrading to v1.66.0
+
+## Delegation of email validation no longer supported
+
+As of this version, Synapse no longer allows the tasks of verifying email address
+ownership, and password reset confirmation, to be delegated to an identity server.
+This removal was previously planned for Synapse 1.64.0, but was
+[delayed](https://github.com/matrix-org/synapse/issues/13421) until now to give
+homeserver administrators more notice of the change.
+
+To continue to allow users to add email addresses to their homeserver accounts,
+and perform password resets, make sure that Synapse is configured with a working
+email server in the [`email` configuration
+section](https://matrix-org.github.io/synapse/latest/usage/configuration/config_documentation.html#email)
+(including, at a minimum, a `notif_from` setting.)
+
+Specifying an `email` setting under `account_threepid_delegates` will now cause
+an error at startup.

+
+Help!! Synapse is slow and eats all my RAM/CPU!
+-----------------------------------------------
+
+First, ensure you are running the latest version of Synapse, using Python 3
+with a [PostgreSQL database](../../postgres.md).
+
+Synapse's architecture is quite RAM hungry currently - we deliberately
+cache a lot of recent room data and metadata in RAM in order to speed up
+common requests. We'll improve this in the future, but for now the easiest
+way to either reduce the RAM usage (at the risk of slowing things down)
+is to set the almost-undocumented ``SYNAPSE_CACHE_FACTOR`` environment
+variable. The default is 0.5, which can be decreased to reduce RAM usage
+in memory constrained environments, or increased if performance starts to
+degrade.
+
+However, degraded performance due to a low cache factor, common on
+machines with slow disks, often leads to explosions in memory use due
+backlogged requests. In this case, reducing the cache factor will make
+things worse. Instead, try increasing it drastically. 2.0 is a good
+starting value.
+
+Using [libjemalloc](https://jemalloc.net) can also yield a significant
+improvement in overall memory use, and especially in terms of giving back
+RAM to the OS. To use it, the library must simply be put in the
+LD_PRELOAD environment variable when launching Synapse. On Debian, this
+can be done by installing the `libjemalloc1` package and adding this
+line to `/etc/default/matrix-synapse`:
+
+    LD_PRELOAD=/usr/lib/x86_64-linux-gnu/libjemalloc.so.1
+
+This made a significant difference on Python 2.7 - it's unclear how
+much of an improvement it provides on Python 3.x.
+
+If you're encountering high CPU use by the Synapse process itself, you
+may be affected by a bug with presence tracking that leads to a
+massive excess of outgoing federation requests (see [discussion](https://github.com/matrix-org/synapse/issues/3971)). If metrics
+indicate that your server is also issuing far more outgoing federation
+requests than can be accounted for by your users' activity, this is a
+likely cause. The misbehavior can be worked around by disabling presence
+in the Synapse config file: [see here](../configuration/config_documentation.md#presence).
+
+
+Running out of File Handles
+---------------------------
+
+If Synapse runs out of file handles, it typically fails badly - live-locking
+at 100% CPU, and/or failing to accept new TCP connections (blocking the
+connecting client).  Matrix currently can legitimately use a lot of file handles,
+thanks to busy rooms like `#matrix:matrix.org` containing hundreds of participating
+servers.  The first time a server talks in a room it will try to connect
+simultaneously to all participating servers, which could exhaust the available
+file descriptors between DNS queries & HTTPS sockets, especially if DNS is slow
+to respond. (We need to improve the routing algorithm used to be better than
+full mesh, but as of March 2019 this hasn't happened yet).
+
+If you hit this failure mode, we recommend increasing the maximum number of
+open file handles to be at least 4096 (assuming a default of 1024 or 256).
+This is typically done by editing ``/etc/security/limits.conf``
+
+Separately, Synapse may leak file handles if inbound HTTP requests get stuck
+during processing - e.g. blocked behind a lock or talking to a remote server etc.
+This is best diagnosed by matching up the 'Received request' and 'Processed request'
+log lines and looking for any 'Processed request' lines which take more than
+a few seconds to execute. Please let us know at [`#synapse:matrix.org`](https://matrix.to/#/#synapse-dev:matrix.org) if
+you see this failure mode so we can help debug it, however.

+# Monthly Active Users
+
+Synapse can be configured to record the number of monthly active users (also referred to as MAU) on a given homeserver.
+For clarity's sake, MAU only tracks local users.
+
+Please note that the metrics recorded by the [Homeserver Usage Stats](../../usage/administration/monitoring/reporting_homeserver_usage_statistics.md)
+are calculated differently. The `monthly_active_users` from the usage stats does not take into account any
+of the rules below, and counts any users who have made a request to the homeserver in the last 30 days.
+
+See the [configuration manual](../../usage/configuration/config_documentation.md#limit_usage_by_mau) for details on how to configure MAU.
+
+## Calculating active users
+
+Individual user activity is measured in active days. If a user performs an action, the exact time of that action is then recorded. When
+calculating the MAU figure, any users with a recorded action in the last 30 days are considered part of the cohort. Days are measured
+as a rolling window from the current system time to 30 days ago.
+
+So for example, if Synapse were to calculate the active users on the 15th July at 13:25, it would include any activity from 15th June 13:25 onwards.
+
+A user is **never** considered active if they are either:
+ - Part of the trial day cohort (described below)
+ - Owned by an application service.
+   - Note: This **only** covers users that are part of an application service `namespaces.users` registration. The namespace
+     must also be marked as `exclusive`.
+
+Otherwise, any request to Synapse will mark the user as active. Please note that registration will not mark a user as active *unless* 
+they register with a 3pid that is included in the config field `mau_limits_reserved_threepids`.
+
+The Prometheus metric for MAU is refreshed every 5 minutes.
+
+Once an hour, Synapse checks to see if any users are inactive (with only activity timestamps later than 30 days). These users
+are removed from the active users cohort. If they then become active, they are immediately restored to the cohort.
+
+It is important to note that **deactivated** users are not immediately removed from the pool of active users, but as these users won't
+perform actions they will eventually be removed from the cohort.
+
+### Trial days
+
+If the config option `mau_trial_days` is set, a user must have been active this many days **after** registration to be active. A user is in the
+trial period if their registration timestamp (also known as the `creation_ts`) is less than `mau_trial_days` old.
+
+As an example, if `mau_trial_days` is set to `3` and a user is active **after** 3 days (72 hours from registration time) then they will be counted as active.
+
+The `mau_appservice_trial_days` config further extends this rule by applying different durations depending on the `appservice_id` of the user.
+Users registered by an application service will be recorded with an `appservice_id` matching the `id` key in the registration file for that service.
+
+
+## Limiting usage of the homeserver when the maximum MAU is reached
+
+If both config options `limit_usage_by_mau` and `max_mau_value` is set, and the current MAU value exceeds the maximum value, the 
+homeserver will begin to block some actions.
+
+Individual users matching **any** of the below criteria never have their actions blocked:
+  - Considered part of the cohort of MAU users.
+  - Considered part of the trial period.
+  - Registered as a `support` user.
+  - Application service users if `track_appservice_user_ips` is NOT set.
+
+Please not that server admins are **not** exempt from blocking.
+
+The following actions are blocked when the MAU limit is exceeded:
+  - Logging in
+  - Sending events
+  - Creating rooms
+  - Syncing
+
+Registration is also blocked for all new signups *unless* the user is registering with a threepid included in the `mau_limits_reserved_threepids`
+config value.
+
+When a request is blocked, the response will have the `errcode` `M_RESOURCE_LIMIT_EXCEEDED`.
+
+## Metrics
+
+Synapse records several different prometheus metrics for MAU.
+
+`synapse_admin_mau:current` records the current MAU figure for native (non-application-service) users.
+
+`synapse_admin_mau:max` records the maximum MAU as dictated by the `max_mau_value` config value.
+
+`synapse_admin_mau_current_mau_by_service` records the current MAU including application service users. The label `app_service` can be used
+to filter by a specific service ID. This *also* includes non-application-service users under `app_service=native` .
+
+`synapse_admin_mau:registered_reserved_users` records the number of users specified in `mau_limits_reserved_threepids` which have
+registered accounts on the homeserver.

-are ones that do specific processing unrelated to requests, e.g. the `pusher`
-that handles sending out push notifications for new events. The intention is for
-all these to be folded into the `generic_worker` app and to use config to define
-which processes handle the various proccessing such as push notifications.
+The following used to be separate worker application types, but are now
+equivalent to `synapse.app.generic_worker`:
+
+ * `synapse.app.client_reader`
+ * `synapse.app.event_creator`
+ * `synapse.app.federation_reader`
+ * `synapse.app.frontend_proxy`
+ * `synapse.app.synchrotron`
 
 
 ## Migration from old config
 
-There are two main independent changes that have been made: introducing Redis
-support and merging apps into `synapse.app.generic_worker`. Both these changes
-are backwards compatible and so no changes to the config are required, however
-server admins are encouraged to plan to migrate to Redis as the old style direct
-TCP replication config is deprecated.
-
-To migrate to Redis add the `redis` config as above, and optionally remove the
-TCP `replication` listener from master and `worker_replication_port` from worker
-config.
+A main change that has occurred is the merging of worker apps into
+`synapse.app.generic_worker`. This change is backwards compatible and so no
+changes to the config are required.

 `worker_app` option in the worker configs, and where worker are started (e.g.

+//! An implementation of Matrix push rules.
+//!
+//! The `Cow<_>` type is used extensively within this module to allow creating
+//! the base rules as constants (in Rust constants can't require explicit
+//! allocation atm).
+//!
+//! ---
+//!
+//! Push rules is the system used to determine which events trigger a push (and a
+//! bump in notification counts).
+//!
+//! This consists of a list of "push rules" for each user, where a push rule is a
+//! pair of "conditions" and "actions". When a user receives an event Synapse
+//! iterates over the list of push rules until it finds one where all the conditions
+//! match the event, at which point "actions" describe the outcome (e.g. notify,
+//! highlight, etc).
+//!
+//! Push rules are split up into 5 different "kinds" (aka "priority classes"), which
+//! are run in order:
+//!     1. Override — highest priority rules, e.g. always ignore notices
+//!     2. Content — content specific rules, e.g. @ notifications
+//!     3. Room — per room rules, e.g. enable/disable notifications for all messages
+//!        in a room
+//!     4. Sender — per sender rules, e.g. never notify for messages from a given
+//!        user
+//!     5. Underride — the lowest priority "default" rules, e.g. notify for every
+//!        message.
+//!
+//! The set of "base rules" are the list of rules that every user has by default. A
+//! user can modify their copy of the push rules in one of three ways:

+A script which enforces that Synapse always uses strict types when defining a Pydantic
+model.
+
+Pydantic does not yet offer a strict mode, but it is planned for pydantic v2. See
+
+    https://github.com/pydantic/pydantic/issues/1098
+    https://pydantic-docs.helpmanual.io/blog/pydantic-v2/#strict-mode
+
+until then, this script is a best effort to stop us from introducing type coersion bugs
+(like the infamous stringy power levels fixed in room version 10).
