-# Synapse 1.143.0rc1 (2025-11-18)
-
-## Features
-
-- Support multiple config files in `register_new_matrix_user`. ([\#18784](https://github.com/element-hq/synapse/issues/18784))
-- Remove authentication from `POST /_matrix/client/v1/delayed_events`, and allow calling this endpoint with the update action to take (`send`/`cancel`/`restart`) in the request path instead of the body. ([\#19152](https://github.com/element-hq/synapse/issues/19152))
-
-## Bugfixes
-
-- Fixed a longstanding bug where background updates were only run on the `main` database. ([\#19181](https://github.com/element-hq/synapse/issues/19181))

-- Reduce cardinality of `synapse_storage_events_persisted_events_sep_total` metric by removing `origin_entity` label. This also separates out events sent by local application services by changing the `origin_type` for such events to `application_service`. The `type` field also only tracks common event types, and anything else is bucketed under `*other*`.

-- Bump lower bounds of dependencies `parameterized` to `0.9.0` and `idna` to `3.3` as those are the first to advertise support for Python 3.10. ([\#19167](https://github.com/element-hq/synapse/issues/19167))
-- Point out which event caused the exception when checking [MSC4293](https://github.com/matrix-org/matrix-spec-proposals/pull/4293) redactions. ([\#19169](https://github.com/element-hq/synapse/issues/19169))

-
-# Synapse 1.142.0 (2025-11-11)
-
-## Dropped support for Python 3.9
-
-This release drops support for Python 3.9, in line with our [dependency
-deprecation
-policy](https://element-hq.github.io/synapse/latest/deprecation_policy.html#platform-dependencies),
-as it is now [end of life](https://endoflife.date/python).
-
-## SQLite 3.40.0+ is now required
-
-The minimum supported SQLite version has been increased from 3.27.0 to 3.40.0.
-
-If you use current versions of the
-[matrixorg/synapse](setup/installation.html#docker-images-and-ansible-playbooks)
-Docker images, no action is required.
-
-
-## Deprecation of MacOS Python wheels
-
-The team has decided to deprecate and eventually stop publishing python wheels
-for MacOS. This is a burden on the team, and we're not aware of any parties
-that use them. Synapse docker images will continue to work on MacOS, as will
-building Synapse from source (though note this requires a Rust compiler).
-
-At present, publishing MacOS Python wheels will continue for the next release
-(1.143.0), but will not be available after that (1.144.0+). If you do make use
-of these wheels downstream, please reach out to us in
-[#synapse-dev:matrix.org](https://matrix.to/#/#synapse-dev:matrix.org). We'd
-love to hear from you!
-

-
-
-
-
-# Synapse 1.142.0rc3 (2025-11-04)

-There is no support provided by Element unless you have a subscription from
-Element.
+Subscription
+============
 
-🚀 Getting started
-==================
+For those that need an enterprise-ready solution, Element
+Server Suite (ESS) is `available via subscription <https://element.io/pricing>`_.
+ESS builds on Synapse to offer a complete Matrix-based backend including the full
+`Admin Console product <https://element.io/enterprise-functionality/admin-console>`_,
+giving admins the power to easily manage an organization-wide
+deployment. It includes advanced identity management, auditing,
+moderation and data retention options as well as Long-Term Support and
+SLAs. ESS supports any Matrix-compatible client.
 
-This component is developed and maintained by `Element <https://element.io>`_.
-It gets shipped as part of the **Element Server Suite (ESS)** which provides the
-official means of deployment.
+.. contents::
 
-ESS is a Matrix distribution from Element with focus on quality and ease of use.
-It ships a full Matrix stack tailored to the respective use case.
+🛠️ Installation and configuration
+==================================
 
-There are three editions of ESS:
+The Synapse documentation describes `how to install Synapse <https://element-hq.github.io/synapse/latest/setup/installation.html>`_. We recommend using
+`Docker images <https://element-hq.github.io/synapse/latest/setup/installation.html#docker-images-and-ansible-playbooks>`_ or `Debian packages from Matrix.org
+<https://element-hq.github.io/synapse/latest/setup/installation.html#matrixorg-packages>`_.
 
-- `ESS Community <https://github.com/element-hq/ess-helm>`_ - the free Matrix
-  distribution from Element tailored to small-/mid-scale, non-commercial
-  community use cases
-- `ESS Pro <https://element.io/server-suite>`_ - the commercial Matrix
-  distribution from Element for professional use
-- `ESS TI-M <https://element.io/server-suite/ti-messenger>`_ - a special version
-  of ESS Pro focused on the requirements of TI-Messenger Pro and ePA as
-  specified by the German National Digital Health Agency Gematik
+.. _federation:
+
+Synapse has a variety of `config options
+<https://element-hq.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://element-hq.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://element-hq.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://element-hq.github.io/synapse/develop/upgrade.html
 
 
-🛠️ Standalone installation and configuration
-============================================
+Platform dependencies
+---------------------
 
-The Synapse documentation describes `options for installing Synapse standalone
-<https://element-hq.github.io/synapse/latest/setup/installation.html>`_. See
-below for more useful documentation links.
+Synapse uses a number of platform dependencies such as Python and PostgreSQL,
+and aims to follow supported upstream versions. See the
+`deprecation policy <https://element-hq.github.io/synapse/latest/deprecation_policy.html>`_
+for more details.
 
-- `Synapse configuration options <https://element-hq.github.io/synapse/latest/usage/configuration/config_documentation.html>`_
-- `Synapse configuration for federation <https://element-hq.github.io/synapse/latest/federate.html>`_

-- `Upgrading Synapse <https://element-hq.github.io/synapse/develop/upgrade.html>`_
 
+Security note
+-------------
+
+Matrix serves raw, user-supplied data in some APIs -- specifically the `content
+repository endpoints`_.
+
+.. _content repository endpoints: https://matrix.org/docs/spec/client_server/latest.html#get-matrix-media-r0-download-servername-mediaid
+
+Whilst we make a reasonable effort to mitigate against XSS attacks (for
+instance, by using `CSP`_), a Matrix homeserver should not be hosted on a
+domain hosting other web applications. This especially applies to sharing
+the domain with Matrix web clients and other sensitive applications like
+webmail. See
+https://developer.github.com/changes/2014-04-25-user-content-security for more
+information.
+
+.. _CSP: https://github.com/matrix-org/synapse/pull/1021
+
+Ideally, the homeserver should not simply be on a different subdomain, but on
+a completely different `registered domain`_ (also known as top-level site or
+eTLD+1). This is because `some attacks`_ are still possible as long as the two
+applications share the same registered domain.
+
+.. _registered domain: https://tools.ietf.org/html/draft-ietf-httpbis-rfc6265bis-03#section-2.3
+
+.. _some attacks: https://en.wikipedia.org/wiki/Session_fixation#Attacks_using_cross-subdomain_cookie
+
+To illustrate this with an example, if your Element Web or other sensitive web
+application is hosted on ``A.example1.com``, you should ideally host Synapse on
+``example2.com``. Some amount of protection is offered by hosting on
+``B.example1.com`` instead, so this is also acceptable in some scenarios.
+However, you should *not* host your Synapse on ``A.example1.com``.
+
+Note that all of the above refers exclusively to the domain used in Synapse's
+``public_baseurl`` setting. In particular, it has no bearing on the domain
+mentioned in MXIDs hosted on that server.
+
+Following this advice ensures that even if an XSS is found in Synapse, the
+impact to other applications will be minimal.
+
+
+🧪 Testing a new installation
+=============================
+
+The easiest way to try out your new Synapse installation is by connecting to it
+from a web client.
+
+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://element-hq.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/ecosystem/clients/>`_.
+
+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:
+
+1. In the
+   `registration config section <https://element-hq.github.io/synapse/latest/usage/configuration/config_documentation.html#registration>`_
+   set ``enable_registration: true`` in ``homeserver.yaml``.
+2. Then **either**:
+
+   a. set up a `CAPTCHA <https://element-hq.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 targeting the rest of the Matrix
+federation.
+
+Your new Matrix ID will be formed partly from the ``server_name``, and partly
+from a localpart you specify when you create the account in 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 'Username' box.

+🪪 Identity Servers
+===================
+
+Identity servers have the job of mapping email addresses and other 3rd Party
+IDs (3PIDs) to Matrix user IDs, as well as verifying the ownership of 3PIDs
+before creating that mapping.
+
+**Identity servers do not store accounts or credentials - these are stored and managed on homeservers.
+Identity Servers are just for mapping 3rd Party IDs to Matrix IDs.**
+
+This process is highly security-sensitive, as there is an obvious risk of spam if it
+is too easy to sign up for Matrix accounts or harvest 3PID data. In the longer
+term, we hope to create a decentralised system to manage it (`matrix-doc #712
+<https://github.com/matrix-org/matrix-doc/issues/712>`_), but in the meantime,
+the role of managing trusted identity in the Matrix ecosystem is farmed out to
+a cluster of known trusted ecosystem partners, who run 'Matrix Identity
+Servers' such as `Sydent <https://github.com/matrix-org/sydent>`_, whose role
+is purely to authenticate and track 3PID logins and publish end-user public
+keys.
+
+You can host your own copy of Sydent, but this will prevent you reaching other
+users in the Matrix ecosystem via their email address, and prevent them finding
+you. We therefore recommend that you use one of the centralised identity servers
+at ``https://matrix.org`` or ``https://vector.im`` for now.
+
+To reiterate: the Identity server will only be used if you choose to associate
+an email address with your account, or send an invite to another user via their
+email address.

-## Cheatsheet for creating a new stream
-
-These rough notes and links may help you to create a new stream and add all the
-necessary registration and event handling.
-
-**Create your stream:**
-- [create a stream class and stream row class](https://github.com/element-hq/synapse/blob/4367fb2d078c52959aeca0fe6874539c53e8360d/synapse/replication/tcp/streams/_base.py#L728)
-  - will need an [ID generator](https://github.com/element-hq/synapse/blob/4367fb2d078c52959aeca0fe6874539c53e8360d/synapse/storage/databases/main/thread_subscriptions.py#L75)
-    - may need [writer configuration](https://github.com/element-hq/synapse/blob/4367fb2d078c52959aeca0fe6874539c53e8360d/synapse/config/workers.py#L177), if there isn't already an obvious source of configuration for which workers should be designated as writers to your new stream.
-      - if adding new writer configuration, add Docker-worker configuration, which lets us configure the writer worker in Complement tests: [[1]](https://github.com/element-hq/synapse/blob/4367fb2d078c52959aeca0fe6874539c53e8360d/docker/configure_workers_and_start.py#L331), [[2]](https://github.com/element-hq/synapse/blob/4367fb2d078c52959aeca0fe6874539c53e8360d/docker/configure_workers_and_start.py#L440)
-- most of the time, you will likely introduce a new datastore class for the concept represented by the new stream, unless there is already an obvious datastore that covers it.
-- consider whether it may make sense to introduce a handler
-
-**Register your stream in:**
-- [`STREAMS_MAP`](https://github.com/element-hq/synapse/blob/4367fb2d078c52959aeca0fe6874539c53e8360d/synapse/replication/tcp/streams/__init__.py#L71)
-
-**Advance your stream in:**
-- [`process_replication_position` of your appropriate datastore](https://github.com/element-hq/synapse/blob/4367fb2d078c52959aeca0fe6874539c53e8360d/synapse/storage/databases/main/thread_subscriptions.py#L111)
-  - don't forget the super call
-
-**If you're going to do any caching that needs invalidation from new rows:**
-- add invalidations to [`process_replication_rows` of your appropriate datastore](https://github.com/element-hq/synapse/blob/4367fb2d078c52959aeca0fe6874539c53e8360d/synapse/storage/databases/main/thread_subscriptions.py#L91)

-
-**For streams to be used in sync:**
-- add a new field to [`StreamToken`](https://github.com/element-hq/synapse/blob/4367fb2d078c52959aeca0fe6874539c53e8360d/synapse/types/__init__.py#L1003)
-  - add a new [`StreamKeyType`](https://github.com/element-hq/synapse/blob/4367fb2d078c52959aeca0fe6874539c53e8360d/synapse/types/__init__.py#L999)

-  - locally on the same worker when completing a write, [e.g. in your handler](https://github.com/element-hq/synapse/blob/4367fb2d078c52959aeca0fe6874539c53e8360d/synapse/handlers/thread_subscriptions.py#L139)
-- add the stream in [`bound_future_token`](https://github.com/element-hq/synapse/blob/4367fb2d078c52959aeca0fe6874539c53e8360d/synapse/streams/events.py#L127)

-
-If you believe you have encountered a security issue, see our [Security
-Disclosure Policy](https://element.io/en/security/security-disclosure-policy).
-
-## Content repository
-
-Matrix serves raw, user-supplied data in some APIs — specifically the [content
-repository endpoints](https://matrix.org/docs/spec/client_server/latest.html#get-matrix-media-r0-download-servername-mediaid).
-
-Whilst we make a reasonable effort to mitigate against XSS attacks (for
-instance, by using [CSP](https://github.com/matrix-org/synapse/pull/1021)), a
-Matrix homeserver should not be hosted on a domain hosting other web
-applications. This especially applies to sharing the domain with Matrix web
-clients and other sensitive applications like webmail. See
-https://developer.github.com/changes/2014-04-25-user-content-security for more
-information.
-
-Ideally, the homeserver should not simply be on a different subdomain, but on a
-completely different [registered
-domain](https://tools.ietf.org/html/draft-ietf-httpbis-rfc6265bis-03#section-2.3)
-(also known as top-level site or eTLD+1). This is because [some
-attacks](https://en.wikipedia.org/wiki/Session_fixation#Attacks_using_cross-subdomain_cookie)
-are still possible as long as the two applications share the same registered
-domain.
-
-
-To illustrate this with an example, if your Element Web or other sensitive web
-application is hosted on `A.example1.com`, you should ideally host Synapse on
-`example2.com`. Some amount of protection is offered by hosting on
-`B.example1.com` instead, so this is also acceptable in some scenarios.
-However, you should *not* host your Synapse on `A.example1.com`.
-
-Note that all of the above refers exclusively to the domain used in Synapse's
-`public_baseurl` setting. In particular, it has no bearing on the domain
-mentioned in MXIDs hosted on that server.
-
-Following this advice ensures that even if an XSS is found in Synapse, the
-impact to other applications will be minimal.

+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).
