-Synapse 1.18.0 (2020-07-30)
-===========================
-
-Deprecation Warnings
---------------------
-
-### Docker Tags with `-py3` Suffix
-
-From 10th August 2020, we will no longer publish Docker images with the `-py3` tag suffix. The images tagged with the `-py3` suffix have been identical to the non-suffixed tags since release 0.99.0, and the suffix is obsolete.
-
-On 10th August, we will remove the `latest-py3` tag. Existing per-release tags (such as `v1.18.0-py3`) will not be removed, but no new `-py3` tags will be added.
-
-Scripts relying on the `-py3` suffix will need to be updated.
-
-
-### TCP-based Replication
-
-When setting up worker processes, we now recommend the use of a Redis server for replication. The old direct TCP connection method is deprecated and will be removed in a future release. See [docs/workers.md](https://github.com/matrix-org/synapse/blob/release-v1.18.0/docs/workers.md) for more details.

-
-Synapse 1.16.0 (2020-07-08)
-===========================
-
-No significant changes since 1.16.0rc2.
-
-Note that this release deprecates the `m.login.jwt` login method, renaming it
-to `org.matrix.login.jwt`, as `m.login.jwt` is not part of the Matrix spec.
-Otherwise the behaviour is identical. Synapse will accept both names for now,
-but this may change in a future release.
-
-Synapse 1.16.0rc2 (2020-07-02)
-==============================
-
-Synapse 1.16.0rc2 includes the security fixes released with Synapse 1.15.2.
-Please see [below](#synapse-1152-2020-07-02) for more details.
-
-Improved Documentation
-----------------------
-
-- Update postgres image in example `docker-compose.yaml` to tag `12-alpine`. ([\#7696](https://github.com/matrix-org/synapse/issues/7696))
-
-
-Internal Changes
-----------------

-
-
-Synapse 1.15.2 (2020-07-02)
-===========================
-
-Due to the two security issues highlighted below, server administrators are
-encouraged to update Synapse. We are not aware of these vulnerabilities being
-exploited in the wild.
-
-Security advisory
------------------
-
-* A malicious homeserver could force Synapse to reset the state in a room to a
-  small subset of the correct state. This affects all Synapse deployments which
-  federate with untrusted servers. ([96e9afe6](https://github.com/matrix-org/synapse/commit/96e9afe62500310977dc3cbc99a8d16d3d2fa15c))
-* HTML pages served via Synapse were vulnerable to clickjacking attacks. This
-  predominantly affects homeservers with single-sign-on enabled, but all server
-  administrators are encouraged to upgrade. ([ea26e9a9](https://github.com/matrix-org/synapse/commit/ea26e9a98b0541fc886a1cb826a38352b7599dbe))
-
-  This was reported by [Quentin Gliech](https://sandhose.fr/).

+**The single biggest thing you need to know is: please base your changes on
+the develop branch - *not* master.**
 
- * Please include a [changelog entry](#changelog) with each PR.
+We use the master branch to track the most recent release, so that folks who
+blindly clone the repo and automatically check out master get something that
+works. Develop is the unstable branch where all the development actually
+happens: the workflow is that contributors should fork the develop branch to
+make a 'feature' branch for a particular contribution, and then make a pull
+request to merge this back into the matrix.org 'official' develop branch. We
+use github's pull request workflow to review the contribution, and either ask
+you to make any refinements needed or merge it and make them ourselves. The
+changes will then land on master when we next do a release.
 
- * Please [sign off](#sign-off) your contribution.
+We use [Buildkite](https://buildkite.com/matrix-dot-org/synapse) for continuous
+integration. If your change breaks the build, this will be shown in GitHub, so

-# Picking a database engine
-
-Synapse offers two database engines:
- * [PostgreSQL](https://www.postgresql.org)
- * [SQLite](https://sqlite.org/)
-
-Almost all installations should opt to use PostgreSQL. Advantages include:
-
-* significant performance improvements due to the superior threading and
-  caching model, smarter query optimiser
-* allowing the DB to be run on separate hardware
-
-For information on how to install and use PostgreSQL, please see
-[docs/postgres.md](docs/postgres.md)
-
-By default Synapse uses SQLite and in doing so trades performance for convenience.
-SQLite is only recommended in Synapse for testing purposes or for servers with

+   `/usr/local`.
+2. `su` to the new `_synapse` user and change to their home directory.
+3. Create a new virtualenv: `virtualenv -p python3 ~/.synapse`

+Using PostgreSQL
+================
+
+Synapse offers two database engines:
+ * `SQLite <https://sqlite.org/>`_
+ * `PostgreSQL <https://www.postgresql.org>`_
+
+By default Synapse uses SQLite in and doing so trades performance for convenience.
+SQLite is only recommended in Synapse for testing purposes or for servers with
+light workloads.
+
+Almost all installations should opt to use PostreSQL. Advantages include:
+
+* significant performance improvements due to the superior threading and
+  caching model, smarter query optimiser
+* allowing the DB to be run on separate hardware
+* allowing basic active/backup high-availability with a "hot spare" synapse
+  pointing at the same DB master, as well as enabling DB replication in

 ## ENVIRONMENT
 
   * `SYNAPSE_CACHE_FACTOR`:
-    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.
+    Synapse's architecture is quite RAM hungry currently - a lot of

+    SYNAPSE_CACHE_FACTOR of 1.0 will max out at around 3-4GB of
+    resident memory - this is what we currently run the matrix.org
+    on. The default setting is currently 0.1, which is probably around
+    a ~700MB footprint. You can dial it down further to 0.02 if
+    desired, which targets roughly ~512MB. Conversely you can dial it
+    up if you need performance for lots of users and have a box with a
+    lot of RAM.

-
-The Delete Room admin API allows server admins to remove rooms from server
-and block these rooms.
-It is a combination and improvement of "[Shutdown room](shutdown_room.md)"
-and "[Purge room](purge_room.md)" API.
-
-Shuts down a room. Moves all local users and room aliases automatically to a
-new room if `new_room_user_id` is set. Otherwise local users only
-leave the room without any information.
-
-The new room will be created with the user specified by the `new_room_user_id` parameter
-as room administrator and will contain a message explaining what happened. Users invited
-to the new room will have power level `-10` by default, and thus be unable to speak.
-
-If `block` is `True` it prevents new joins to the old room.
-
-This API will remove all trace of the old room from your database after removing
-all local users. If `purge` is `true` (the default), all traces of the old room will
-be removed from your database after removing all local users. If you do not want
-this to happen, set `purge` to `false`.
-Depending on the amount of history being purged a call to the API may take
-several minutes or longer.
-
-The local server will only have the power to move local user and room aliases to
-the new room. Users on other servers will be unaffected.
-
-The API is:
-
-```json

-      from the old room. The user ID must be on the local server, but does not necessarily
-      have to belong to a registered user.
-* `room_name` - Optional. A string representing the name of the room that new users will be
-                invited to. Defaults to `Content Violation Notification`
-* `message` - Optional. A string containing the first message that will be sent as
-              `new_room_user_id` in the new room. Ideally this will clearly convey why the
-               original room was shut down. Defaults to `Sharing illegal content on this server
-               is not permitted and rooms in violation will be blocked.`
-* `block` - Optional. If set to `true`, this room will be added to a blocking list, preventing
-            future attempts to join the room. Defaults to `false`.
-* `purge` - Optional. If set to `true`, it will remove all traces of the room from your database.

-## Undoing room shutdowns
-
-*Note*: This guide may be outdated by the time you read it. By nature of room shutdowns being performed at the database level,
-the structure can and does change without notice.
-
-First, it's important to understand that a room shutdown is very destructive. Undoing a shutdown is not as simple as pretending it
-never happened - work has to be done to move forward instead of resetting the past. In fact, in some cases it might not be possible
-to recover at all:
-
-* If the room was invite-only, your users will need to be re-invited.
-* If the room no longer has any members at all, it'll be impossible to rejoin.
-* The first user to rejoin will have to do so via an alias on a different server.
-
-With all that being said, if you still want to try and recover the room:
-
-1. For safety reasons, shut down Synapse.
-2. In the database, run `DELETE FROM blocked_rooms WHERE room_id = '!example:example.org';`
-   * For caution: it's recommended to run this in a transaction: `BEGIN; DELETE ...;`, verify you got 1 result, then `COMMIT;`.
-   * The room ID is the same one supplied to the shutdown room API, not the Content Violation room.
-3. Restart Synapse.
-
-You will have to manually handle, if you so choose, the following:
-
-* Aliases that would have been redirected to the Content Violation room.
-* Users that would have been booted from the room (and will have been force-joined to the Content Violation room).
-* Removal of the Content Violation room if desired.

-Some notes on how we use git
-============================
-
-On keeping the commit history clean
------------------------------------
-
-In an ideal world, our git commit history would be a linear progression of
-commits each of which contains a single change building on what came
-before. Here, by way of an arbitrary example, is the top of `git log --graph
-b2dba0607`:
-
-<img src="git/clean.png" alt="clean git graph" width="500px">
-
-Note how the commit comment explains clearly what is changing and why. Also
-note the *absence* of merge commits, as well as the absence of commits called
-things like (to pick a few culprits):
-[“pep8”](https://github.com/matrix-org/synapse/commit/84691da6c), [“fix broken
-test”](https://github.com/matrix-org/synapse/commit/474810d9d),
-[“oops”](https://github.com/matrix-org/synapse/commit/c9d72e457),
-[“typo”](https://github.com/matrix-org/synapse/commit/836358823), or [“Who's
-the president?”](https://github.com/matrix-org/synapse/commit/707374d5d).
-
-There are a number of reasons why keeping a clean commit history is a good
-thing:
-
- * From time to time, after a change lands, it turns out to be necessary to
-   revert it, or to backport it to a release branch. Those operations are
-   *much* easier when the change is contained in a single commit.
-
- * Similarly, it's much easier to answer questions like “is the fix for
-   `/publicRooms` on the release branch?” if that change consists of a single
-   commit.
-
- * Likewise: “what has changed on this branch in the last week?” is much
-   clearer without merges and “pep8” commits everywhere.
-
- * Sometimes we need to figure out where a bug got introduced, or some
-   behaviour changed. One way of doing that is with `git bisect`: pick an
-   arbitrary commit between the known good point and the known bad point, and
-   see how the code behaves. However, that strategy fails if the commit you
-   chose is the middle of someone's epic branch in which they broke the world
-   before putting it back together again.
-
-One counterargument is that it is sometimes useful to see how a PR evolved as
-it went through review cycles. This is true, but that information is always
-available via the GitHub UI (or via the little-known [refs/pull
-namespace](https://help.github.com/en/github/collaborating-with-issues-and-pull-requests/checking-out-pull-requests-locally)).
-
-
-Of course, in reality, things are more complicated than that. We have release
-branches as well as `develop` and `master`, and we deliberately merge changes
-between them. Bugs often slip through and have to be fixed later. That's all
-fine: this not a cast-iron rule which must be obeyed, but an ideal to aim
-towards.
-
-Merges, squashes, rebases: wtf?
--------------------------------
-
-Ok, so that's what we'd like to achieve. How do we achieve it?
-
-The TL;DR is: when you come to merge a pull request, you *probably* want to
-“squash and merge”:
-
-![squash and merge](git/squash.png).
-
-(This applies whether you are merging your own PR, or that of another
-contributor.)
-
-“Squash and merge”<sup id="a1">[1](#f1)</sup> takes all of the changes in the
-PR, and bundles them into a single commit. GitHub gives you the opportunity to
-edit the commit message before you confirm, and normally you should do so,
-because the default will be useless (again: `* woops typo` is not a useful
-thing to keep in the historical record).
-
-The main problem with this approach comes when you have a series of pull
-requests which build on top of one another: as soon as you squash-merge the
-first PR, you'll end up with a stack of conflicts to resolve in all of the
-others. In general, it's best to avoid this situation in the first place by
-trying not to have multiple related PRs in flight at the same time. Still,
-sometimes that's not possible and doing a regular merge is the lesser evil.
-
-Another occasion in which a regular merge makes more sense is a PR where you've
-deliberately created a series of commits each of which makes sense in its own
-right. For example: [a PR which gradually propagates a refactoring operation
-through the codebase](https://github.com/matrix-org/synapse/pull/6837), or [a
-PR which is the culmination of several other
-PRs](https://github.com/matrix-org/synapse/pull/5987). In this case the ability
-to figure out when a particular change/bug was introduced could be very useful.
-
-Ultimately: **this is not a hard-and-fast-rule**. If in doubt, ask yourself “do
-each of the commits I am about to merge make sense in their own right”, but
-remember that we're just doing our best to balance “keeping the commit history
-clean” with other factors.
-
-Git branching model
--------------------
-
-A [lot](https://nvie.com/posts/a-successful-git-branching-model/)
-[of](http://scottchacon.com/2011/08/31/github-flow.html)
-[words](https://www.endoflineblog.com/gitflow-considered-harmful) have been
-written in the past about git branching models (no really, [a
-lot](https://martinfowler.com/articles/branching-patterns.html)). I tend to
-think the whole thing is overblown. Fundamentally, it's not that
-complicated. Here's how we do it.
-
-Let's start with a picture:
-
-![branching model](git/branches.jpg)
-
-It looks complicated, but it's really not. There's one basic rule: *anyone* is
-free to merge from *any* more-stable branch to *any* less-stable branch at
-*any* time<sup id="a2">[2](#f2)</sup>. (The principle behind this is that if a
-change is good enough for the more-stable branch, then it's also good enough go
-put in a less-stable branch.)
-
-Meanwhile, merging (or squashing, as per the above) from a less-stable to a
-more-stable branch is a deliberate action in which you want to publish a change
-or a set of changes to (some subset of) the world: for example, this happens
-when a PR is landed, or as part of our release process.
-
-So, what counts as a more- or less-stable branch? A little reflection will show
-that our active branches are ordered thus, from more-stable to less-stable:
-
- * `master` (tracks our last release).
- * `release-vX.Y.Z` (the branch where we prepare the next release)<sup
-   id="a3">[3](#f3)</sup>.
- * PR branches which are targeting the release.
- * `develop` (our "mainline" branch containing our bleeding-edge).
- * regular PR branches.
-
-The corollary is: if you have a bugfix that needs to land in both
-`release-vX.Y.Z` *and* `develop`, then you should base your PR on
-`release-vX.Y.Z`, get it merged there, and then merge from `release-vX.Y.Z` to
-`develop`. (If a fix lands in `develop` and we later need it in a
-release-branch, we can of course cherry-pick it, but landing it in the release
-branch first helps reduce the chance of annoying conflicts.)
-
----
-
-<b id="f1">[1]</b>: “Squash and merge” is GitHub's term for this
-operation. Given that there is no merge involved, I'm not convinced it's the
-most intuitive name. [^](#a1)
-
-<b id="f2">[2]</b>: Well, anyone with commit access.[^](#a2)
-
-<b id="f3">[3]</b>: Very, very occasionally (I think this has happened once in
-the history of Synapse), we've had two releases in flight at once. Obviously,
-`release-v1.2.3` is more-stable than `release-v1.3.0`. [^](#a3)

+# How to test OpenID Connect
+
+Any OpenID Connect Provider (OP) should work with Synapse, as long as it supports the authorization code flow.
+There are a few options for that:
+
+ - start a local OP. Synapse has been tested with [Hydra][hydra] and [Dex][dex-idp].
+   Note that for an OP to work, it should be served under a secure (HTTPS) origin.
+   A certificate signed with a self-signed, locally trusted CA should work. In that case, start Synapse with a `SSL_CERT_FILE` environment variable set to the path of the CA.
+ - use a publicly available OP. Synapse has been tested with [Google][google-idp].
+ - setup a SaaS OP, like [Auth0][auth0] and [Okta][okta]. Auth0 has a free tier which has been tested with Synapse.

+[hydra]: https://www.ory.sh/docs/hydra/
+
+
+## Sample configs
+
+Here are a few configs for providers that should work with Synapse.
+
+### [Dex][dex-idp]
+
+[Dex][dex-idp] is a simple, open-source, certified OpenID Connect Provider.
+Although it is designed to help building a full-blown provider, with some external database, it can be configured with static passwords in a config file.
+
+Follow the [Getting Started guide](https://github.com/dexidp/dex/blob/master/Documentation/getting-started.md) to install Dex.
+
+Edit `examples/config-dev.yaml` config file from the Dex repo to add a client:
+
+```yaml
+staticClients:
+- id: synapse
+  secret: secret
+  redirectURIs:
+  - '[synapse base url]/_synapse/oidc/callback'
+  name: 'Synapse'
+```
+
+Run with `dex serve examples/config-dex.yaml`
+
+Synapse config:
+
+```yaml
+oidc_config:
+   enabled: true
+   skip_verification: true # This is needed as Dex is served on an insecure endpoint
+   issuer: "http://127.0.0.1:5556/dex"
+   discover: true
+   client_id: "synapse"
+   client_secret: "secret"
+   scopes:
+     - openid
+     - profile
+   user_mapping_provider:
+     config:
+       localpart_template: '{{ user.name }}'
+       display_name_template: '{{ user.name|capitalize }}'
+```
+
+### [Auth0][auth0]
+
+1. Create a regular web application for Synapse
+2. Set the Allowed Callback URLs to `[synapse base url]/_synapse/oidc/callback`
+3. Add a rule to add the `preferred_username` claim.
+   <details>
+    <summary>Code sample</summary>
+
+    ```js
+    function addPersistenceAttribute(user, context, callback) {
+      user.user_metadata = user.user_metadata || {};
+      user.user_metadata.preferred_username = user.user_metadata.preferred_username || user.user_id;
+      context.idToken.preferred_username = user.user_metadata.preferred_username;
+
+      auth0.users.updateUserMetadata(user.user_id, user.user_metadata)
+        .then(function(){
+            callback(null, user, context);
+        })
+        .catch(function(err){
+            callback(err);
+        });
+    }
+    ```
+
+  </details>
+
+
+```yaml
+oidc_config:
+   enabled: true
+   issuer: "https://your-tier.eu.auth0.com/" # TO BE FILLED
+   discover: true
+   client_id: "your-client-id" # TO BE FILLED
+   client_secret: "your-client-secret" # TO BE FILLED
+   scopes:
+     - openid
+     - profile
+   user_mapping_provider:
+     config:
+       localpart_template: '{{ user.preferred_username }}'
+       display_name_template: '{{ user.name }}'
+```
+
+### GitHub
+
+GitHub is a bit special as it is not an OpenID Connect compliant provider, but just a regular OAuth2 provider.
+The `/user` API endpoint can be used to retrieve informations from the user.
+As the OIDC login mechanism needs an attribute to uniquely identify users and that endpoint does not return a `sub` property, an alternative `subject_claim` has to be set.
+
+1. Create a new OAuth application: https://github.com/settings/applications/new
+2. Set the callback URL to `[synapse base url]/_synapse/oidc/callback`
+
+```yaml
+oidc_config:
+   enabled: true
+   issuer: "https://github.com/"
+   discover: false
+   client_id: "your-client-id" # TO BE FILLED
+   client_secret: "your-client-secret" # TO BE FILLED
+   authorization_endpoint: "https://github.com/login/oauth/authorize"
+   token_endpoint: "https://github.com/login/oauth/access_token"
+   userinfo_endpoint: "https://api.github.com/user"
+   scopes:
+     - read:user
+   user_mapping_provider:
+     config:
+       subject_claim: 'id'
+       localpart_template: '{{ user.login }}'
+       display_name_template: '{{ user.name }}'
+```
+
+### Google
+
+1. Setup a project in the Google API Console
+2. Obtain the OAuth 2.0 credentials (see <https://developers.google.com/identity/protocols/oauth2/openid-connect>)
+3. Add this Authorized redirect URI: `[synapse base url]/_synapse/oidc/callback`
+
+```yaml
+oidc_config:
+   enabled: true
+   issuer: "https://accounts.google.com/"
+   discover: true
+   client_id: "your-client-id" # TO BE FILLED
+   client_secret: "your-client-secret" # TO BE FILLED
+   scopes:
+     - openid
+     - profile
+   user_mapping_provider:
+     config:
+       localpart_template: '{{ user.given_name|lower }}'
+       display_name_template: '{{ user.name }}'
+```
+
+### Twitch
+
+1. Setup a developer account on [Twitch](https://dev.twitch.tv/)
+2. Obtain the OAuth 2.0 credentials by [creating an app](https://dev.twitch.tv/console/apps/)
+3. Add this OAuth Redirect URL: `[synapse base url]/_synapse/oidc/callback`
+
+```yaml
+oidc_config:
+   enabled: true
+   issuer: "https://id.twitch.tv/oauth2/"
+   discover: true
+   client_id: "your-client-id" # TO BE FILLED
+   client_secret: "your-client-secret" # TO BE FILLED
+   client_auth_method: "client_secret_post"
+   scopes:
+     - openid
+   user_mapping_provider:
+     config:
+       localpart_template: '{{ user.preferred_username }}'
+       display_name_template: '{{ user.name }}'
+```

-# JWT Login Type
-
-Synapse comes with a non-standard login type to support
-[JSON Web Tokens](https://en.wikipedia.org/wiki/JSON_Web_Token). In general the
-documentation for
-[the login endpoint](https://matrix.org/docs/spec/client_server/r0.6.1#login)
-is still valid (and the mechanism works similarly to the
-[token based login](https://matrix.org/docs/spec/client_server/r0.6.1#token-based)).
-
-To log in using a JSON Web Token, clients should submit a `/login` request as
-follows:
-
-```json
-{
-  "type": "org.matrix.login.jwt",
-  "token": "<jwt>"
-}
-```
-
-Note that the login type of `m.login.jwt` is supported, but is deprecated. This
-will be removed in a future version of Synapse.
-
-The `token` field should include the JSON web token with the following claims:
-
-* The `sub` (subject) claim is required and should encode the local part of the
-  user ID.
-* The expiration time (`exp`), not before time (`nbf`), and issued at (`iat`)
-  claims are optional, but validated if present.
-* The issuer (`iss`) claim is optional, but required and validated if configured.
-* The audience (`aud`) claim is optional, but required and validated if configured.
-  Providing the audience claim when not configured will cause validation to fail.
-
-In the case that the token is not valid, the homeserver must respond with
-`403 Forbidden` and an error code of `M_FORBIDDEN`.
-
-As with other login types, there are additional fields (e.g. `device_id` and
-`initial_device_display_name`) which can be included in the above request.
-
-## Preparing Synapse
-
-The JSON Web Token integration in Synapse uses the
-[`PyJWT`](https://pypi.org/project/pyjwt/) library, which must be installed
-as follows:
-
- * The relevant libraries are included in the Docker images and Debian packages
-   provided by `matrix.org` so no further action is needed.
-
- * If you installed Synapse into a virtualenv, run `/path/to/env/bin/pip
-   install synapse[pyjwt]` to install the necessary dependencies.
-
- * For other installation mechanisms, see the documentation provided by the
-   maintainer.
-
-To enable the JSON web token integration, you should then add an `jwt_config` section
-to your configuration file (or uncomment the `enabled: true` line in the
-existing section). See [sample_config.yaml](./sample_config.yaml) for some
-sample settings.
-
-## How to test JWT as a developer
-
-Although JSON Web Tokens are typically generated from an external server, the
-examples below use [PyJWT](https://pyjwt.readthedocs.io/en/latest/) directly.
-
-1.  Configure Synapse with JWT logins, note that this example uses a pre-shared
-    secret and an algorithm of HS256:
-
-    ```yaml
-    jwt_config:
-        enabled: true
-        secret: "my-secret-token"
-        algorithm: "HS256"
-    ```
-2.  Generate a JSON web token:
-
-    ```bash
-    $ pyjwt --key=my-secret-token --alg=HS256 encode sub=test-user
-    eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJzdWIiOiJ0ZXN0LXVzZXIifQ.Ag71GT8v01UO3w80aqRPTeuVPBIBZkYhNTJJ-_-zQIc
-    ```
-3.  Query for the login types and ensure `org.matrix.login.jwt` is there:
-
-    ```bash
-    curl http://localhost:8080/_matrix/client/r0/login
-    ```
-4.  Login used the generated JSON web token from above:
-
-    ```bash
-    $ curl http://localhost:8082/_matrix/client/r0/login -X POST \
-        --data '{"type":"org.matrix.login.jwt","token":"eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJzdWIiOiJ0ZXN0LXVzZXIifQ.Ag71GT8v01UO3w80aqRPTeuVPBIBZkYhNTJJ-_-zQIc"}'
-    {
-        "access_token": "<access token>",
-        "device_id": "ACBDEFGHI",
-        "home_server": "localhost:8080",
-        "user_id": "@test-user:localhost:8480"
-    }
-    ```
-
-You should now be able to use the returned access token to query the client API.

-### GitHub
-
-GitHub is a bit special as it is not an OpenID Connect compliant provider, but
-just a regular OAuth2 provider.
-
-The [`/user` API endpoint](https://developer.github.com/v3/users/#get-the-authenticated-user)
-can be used to retrieve information on the authenticated user. As the Synaspse
-login mechanism needs an attribute to uniquely identify users, and that endpoint
-does not return a `sub` property, an alternative `subject_claim` has to be set.
-
-1. Create a new OAuth application: https://github.com/settings/applications/new.
-2. Set the callback URL to `[synapse public baseurl]/_synapse/oidc/callback`.
-

-### Using synctl with workers
-
-If you want to use `synctl` to manage your synapse processes, you will need to
-create an an additional configuration file for the main synapse process. That
-configuration should look like this:
-
-```yaml
-worker_app: synapse.app.homeserver
-```
-
-Additionally, each worker app must be configured with the name of a "pid file",
-to which it will write its process ID when it starts. For example, for a
-synchrotron, you might write:
-
-```yaml
-worker_pid_file: /home/matrix/synapse/worker1.pid
-```
-
-Finally, to actually run your worker-based synapse, you must pass synctl the `-a`
-commandline option to tell it to operate on all the worker configurations found
-in the given directory, e.g.:
-
-    synctl -a $CONFIG/workers start
-
-Currently one should always restart all workers when restarting or upgrading
-synapse, unless you explicitly know it's safe not to.  For instance, restarting
-synapse without restarting all the synchrotrons may result in broken typing
-notifications.
-
-To manipulate a specific worker, you pass the -w option to synctl:

-
-## Setting up workers
-
-A Redis server is required to manage the communication between the processes.
-The Redis server should be installed following the normal procedure for your
-distribution (e.g. `apt install redis-server` on Debian). It is safe to use an
-existing Redis deployment if you have one.
-
-Once installed, check that Redis is running and accessible from the host running
-Synapse, for example by executing `echo PING | nc -q1 localhost 6379` and seeing
-a response of `+PONG`.
-
-The appropriate dependencies must also be installed for Synapse. If using a
-virtualenv, these can be installed with:
-
-```sh
-pip install matrix-synapse[redis]
-```
-
-Note that these dependencies are included when synapse is installed with `pip
-install matrix-synapse[all]`. They are also included in the debian packages from
-`matrix.org` and in the docker images at
-https://hub.docker.com/r/matrixdotorg/synapse/.
+## Configuration
 
 To make effective use of the workers, you will need to configure an HTTP
 reverse-proxy such as nginx or haproxy, which will direct incoming requests to
-the correct worker, or to the main synapse instance. See
-[reverse_proxy.md](reverse_proxy.md) for information on setting up a reverse
-proxy.
-
-When using workers, each worker process has its own configuration file which
-contains settings specific to that worker, such as the HTTP listener that it
-provides (if any), logging configuration, etc.
-
-Normally, the worker processes are configured to read from a shared
-configuration file as well as the worker-specific configuration files. This
-makes it easier to keep common configuration settings synchronised across all
-the processes.
-
-The main process is somewhat special in this respect: it does not normally
-need its own configuration file and can take all of its configuration from the
-shared configuration file.
-
-
-### Shared configuration
-
-Normally, only a couple of changes are needed to make an existing configuration
-file suitable for use with workers. First, you need to enable an "HTTP replication
-listener" for the main process; and secondly, you need to enable redis-based
-replication. For example:
+the correct worker, or to the main synapse instance. Note that this includes
+requests made to the federation port. See [reverse_proxy.md](reverse_proxy.md)
+for information on setting up a reverse proxy.
 
+To enable workers, you need to add *two* replication listeners to the
+main Synapse configuration file (`homeserver.yaml`). For example:
 
 ```yaml
-# extend the existing `listeners` section. This defines the ports that the
-# main process will listen on.
 listeners:
+  # The TCP replication port
+  - port: 9092
+    bind_address: '127.0.0.1'
+    type: replication
+
   # The HTTP replication port
   - port: 9093
     bind_address: '127.0.0.1'
     type: http
     resources:
      - names: [replication]
-
-redis:
-    enabled: true
 ```
 
-See the sample config for the full documentation of each option.
+Under **no circumstances** should these replication API listeners be exposed to
+the public internet; they have no authentication and are unencrypted.
 
-Under **no circumstances** should the replication listener be exposed to the
-public internet; it has no authentication and is unencrypted.
-
-
-### Worker configuration

-### Running Synapse with workers
-
 Finally, you need to start your worker processes. This can be done with either
 `synctl` or your distribution's preferred service manager such as `systemd`. We
 recommend the use of `systemd` where available: for information on setting up
 `systemd` to start synapse workers, see
-[systemd-with-workers](systemd-with-workers). To use `synctl`, see
-[synctl_workers.md](synctl_workers.md).
+[systemd-with-workers](systemd-with-workers). To use `synctl`, see below.
 
+### **Experimental** support for replication over redis
+
+As of Synapse v1.13.0, it is possible to configure Synapse to send replication
+via a [Redis pub/sub channel](https://redis.io/topics/pubsub). This is an
+alternative to direct TCP connections to the master: rather than all the
+workers connecting to the master, all the workers and the master connect to
+Redis, which relays replication commands between processes. This can give a
+significant cpu saving on the master and will be a prerequisite for upcoming
+performance improvements.
+
+Note that this support is currently experimental; you may experience lost
+messages and similar problems! It is strongly recommended that admins setting
+up workers for the first time use direct TCP replication as above.
+
+To configure Synapse to use Redis:
+
+1. Install Redis following the normal procedure for your distribution - for
+   example, on Debian, `apt install redis-server`. (It is safe to use an
+   existing Redis deployment if you have one: we use a pub/sub stream named
+   according to the `server_name` of your synapse server.)
+2. Check Redis is running and accessible: you should be able to `echo PING | nc -q1
+   localhost 6379` and get a response of `+PONG`.
+3. Install the python prerequisites. If you installed synapse into a
+   virtualenv, this can be done with:
+   ```sh
+   pip install matrix-synapse[redis]
+   ```
+   The debian packages from matrix.org already include the required
+   dependencies.
+4. Add config to the shared configuration (`homeserver.yaml`):
+    ```yaml
+    redis:
+      enabled: true
+    ```
+    Optional parameters which can go alongside `enabled` are `host`, `port`,
+    `password`. Normally none of these are required.
+5. Restart master and all workers.
+
+Once redis replication is in use, `worker_replication_port` is redundant and
+can be removed from the worker configuration files. Similarly, the
+configuration for the `listener` for the TCP replication port can be removed
+from the main configuration file. Note that the HTTP replication port is
+still required.
+
+### Using synctl
+
+If you want to use `synctl` to manage your synapse processes, you will need to
+create an an additional configuration file for the master synapse process. That
+configuration should look like this:
+
+```yaml
+worker_app: synapse.app.homeserver
+```
+
+Additionally, each worker app must be configured with the name of a "pid file",
+to which it will write its process ID when it starts. For example, for a
+synchrotron, you might write:
+
+```yaml
+worker_pid_file: /home/matrix/synapse/synchrotron.pid
+```
+
+Finally, to actually run your worker-based synapse, you must pass synctl the `-a`
+commandline option to tell it to operate on all the worker configurations found
+in the given directory, e.g.:
+
+    synctl -a $CONFIG/workers start
+
+Currently one should always restart all workers when restarting or upgrading
+synapse, unless you explicitly know it's safe not to.  For instance, restarting
+synapse without restarting all the synchrotrons may result in broken typing
+notifications.
+
+To manipulate a specific worker, you pass the -w option to synctl:
+
+    synctl -w $CONFIG/workers/synchrotron.yaml restart
 
 ## Available worker applications
 
-### `synapse.app.generic_worker`
+### `synapse.app.pusher`
 
-This worker can handle API requests matching the following regular
-expressions:
+Handles sending push notifications to sygnal and email. Doesn't handle any
+REST endpoints itself, but you should set `start_pushers: False` in the
+shared configuration file to stop the main synapse sending these notifications.
+
+Note this worker cannot be load-balanced: only one instance should be active.
+
+### `synapse.app.synchrotron`
+
+The synchrotron handles `sync` requests from clients. In particular, it can
+handle REST endpoints matching the following regular expressions:
 
-    # Sync requests
     ^/_matrix/client/(v2_alpha|r0)/sync$
     ^/_matrix/client/(api/v1|v2_alpha|r0)/events$
     ^/_matrix/client/(api/v1|r0)/initialSync$
     ^/_matrix/client/(api/v1|r0)/rooms/[^/]+/initialSync$
 
-    # Federation requests
+The above endpoints should all be routed to the synchrotron worker by the
+reverse-proxy configuration.
+
+It is possible to run multiple instances of the synchrotron to scale
+horizontally. In this case the reverse-proxy should be configured to
+load-balance across the instances, though it will be more efficient if all
+requests from a particular user are routed to a single instance. Extracting
+a userid from the access token is currently left as an exercise for the reader.
+
+### `synapse.app.appservice`
+
+Handles sending output traffic to Application Services. Doesn't handle any
+REST endpoints itself, but you should set `notify_appservices: False` in the
+shared configuration file to stop the main synapse sending these notifications.
+
+Note this worker cannot be load-balanced: only one instance should be active.
+
+### `synapse.app.federation_reader`
+
+Handles a subset of federation endpoints. In particular, it can handle REST
+endpoints matching the following regular expressions:

-ensure that the purge history admin API is not used while pagination requests
-for the room are in flight:

-    ^/_matrix/client/(api/v1|r0|unstable)/rooms/.*/messages$

+instance.
 
-Note that a HTTP listener with `client` and `federation` resources must be
-configured in the `worker_listeners` option in the worker config.
-
-
-#### Load balancing
-
-It is possible to run multiple instances of this worker app, with incoming requests
-being load-balanced between them by the reverse-proxy. However, different endpoints
-have different characteristics and so admins
-may wish to run multiple groups of workers handling different endpoints so that
-load balancing can be done in different ways.
-
-For `/sync` and `/initialSync` requests it will be more efficient if all
-requests from a particular user are routed to a single instance. Extracting a
-user ID from the access token or `Authorization` header is currently left as an
-exercise for the reader. Admins may additionally wish to separate out `/sync`
-requests that have a `since` query parameter from those that don't (and
-`/initialSync`), as requests that don't are known as "initial sync" that happens
-when a user logs in on a new device and can be *very* resource intensive, so
-isolating these requests will stop them from interfering with other users ongoing
-syncs.
-
-Federation and client requests can be balanced via simple round robin.
-
-The inbound federation transaction request `^/_matrix/federation/v1/send/`
-should be balanced by source IP so that transactions from the same remote server
-go to the same process.
-
-Registration/login requests can be handled separately purely to help ensure that
-unexpected load doesn't affect new logins and sign ups.
-
-Finally, event sending requests can be balanced by the room ID in the URI (or
-the full URI, or even just round robin), the room ID is the path component after
-`/rooms/`. If there is a large bridge connected that is sending or may send lots
-of events, then a dedicated set of workers can be provisioned to limit the
-effects of bursts of events from that bridge on events sent by normal users.
-
-#### Stream writers
-
-Additionally, there is *experimental* support for moving writing of specific
-streams (such as events) off of the main process to a particular worker. (This
-is only supported with Redis-based replication.)
-
-Currently support streams are `events` and `typing`.
-
-To enable this, the worker must have a HTTP replication listener configured,
-have a `worker_name` and be listed in the `instance_map` config. For example to
-move event persistence off to a dedicated worker, the shared configuration would
-include:
+Note that `federation` must be added to the listener resources in the worker config:
 
 ```yaml
-instance_map:
-    event_persister1:
-        host: localhost
-        port: 8034
-
-stream_writers:

-## 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.
-
-To migrate apps to use `synapse.app.generic_worker` simply update the
-`worker_app` option in the worker configs, and where worker are started (e.g.
-in systemd service files, but not required for synctl).
