-
-## Deprecation of MacOS Python wheels
-
-The team has decided to deprecate and stop publishing python wheels for MacOS.
-Synapse docker images will continue to work on MacOS, as will building Synapse
-from source (though note this requires a Rust compiler).
-
-## Unstable mutual rooms endpoint is now behind an experimental feature flag
-
-Admins using the unstable [MSC2666](https://github.com/matrix-org/matrix-spec-proposals/pull/2666) endpoint (`/_matrix/client/unstable/uk.half-shot.msc2666/user/mutual_rooms`),
-please check [the relevant section in the upgrade notes](https://github.com/element-hq/synapse/blob/develop/docs/upgrade.md#upgrading-to-v11440) as this release contains changes
-that disable that endpoint by default.

-
-## Improved Documentation
-
-- Improve documentation around streams, particularly ID generators and adding new streams. ([\#18943](https://github.com/element-hq/synapse/issues/18943))
-
-## Deprecations and Removals
-
-- Remove support for PostgreSQL 13. ([\#19170](https://github.com/element-hq/synapse/issues/19170))
-
-## Internal Changes
-
-- Provide additional servers with federation room directory results. ([\#18970](https://github.com/element-hq/synapse/issues/18970))
-- Add a shortcut return when there are no events to purge. ([\#19093](https://github.com/element-hq/synapse/issues/19093))
-- Write union types as `X | Y` where possible, as per PEP 604, added in Python 3.10. ([\#19111](https://github.com/element-hq/synapse/issues/19111))
-- 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*`. ([\#19133](https://github.com/element-hq/synapse/issues/19133), [\#19168](https://github.com/element-hq/synapse/issues/19168))

-- Ignore recent Python language refactors from git blame (`.git-blame-ignore-revs`). ([\#19150](https://github.com/element-hq/synapse/issues/19150))
-- 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))

-- Add debug logs to track `Clock` utilities. ([\#19173](https://github.com/element-hq/synapse/issues/19173))
-- Remove explicit python version skips in `cibuildwheel` config as it's no longer required after [#19137](https://github.com/element-hq/synapse/pull/19137). ([\#19177](https://github.com/element-hq/synapse/issues/19177))
-- Fix potential lost logcontext when `PerDestinationQueue.shutdown(...)` is called. ([\#19178](https://github.com/element-hq/synapse/issues/19178))

-# 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 1.136.0 (2025-08-12)
-
-Note: This release includes the security fixes from `1.135.2` and `1.136.0rc2`, detailed below.
-
-### Bugfixes
-
-- Fix bug introduced in 1.135.2 and 1.136.0rc2 where the [Make Room Admin API](https://element-hq.github.io/synapse/latest/admin_api/rooms.html#make-room-admin-api) would not treat a room v12's creator power level as the highest in room. ([\#18805](https://github.com/element-hq/synapse/issues/18805))
-
-
-# Synapse 1.135.2 (2025-08-11)
-
-This is the Synapse portion of the [Matrix coordinated security release](https://matrix.org/blog/2025/07/security-predisclosure/). This release includes support for [room version](https://spec.matrix.org/v1.15/rooms/) 12 which fixes a number of security vulnerabilities, including [CVE-2025-49090](https://www.cve.org/CVERecord?id=CVE-2025-49090).
-
-The default room version is not changed. Not all clients will support room version 12 immediately, and not all users will be using the latest version of their clients. Large, public rooms are advised to wait a few weeks before upgrading to room version 12 to allow users throughout the Matrix ecosystem to update their clients.
-
-Note: release 1.135.1 was skipped due to issues discovered during the release process.
-
-Two patched Synapse releases are now available:
-
-* `1.135.2`: stable release comprised of `1.135.0` + security patches
-    * Upgrade to this release **if you are currently running 1.135.0 or below**.
-* `1.136.0rc2`: unstable release candidate comprised of `1.136.0rc1` + security patches.
-    * Upgrade to this release **only if you are on 1.136.0rc1**.

-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>`_
-- `Using a reverse proxy with Synapse <https://element-hq.github.io/synapse/latest/reverse_proxy.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.

+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.
