-Synapse 1.20.0 (2020-09-22)
-===========================
-
-No significant changes since v1.20.0rc5.
-
-Removal warning
----------------
-
-Historically, the [Synapse Admin
-API](https://github.com/matrix-org/synapse/tree/master/docs) has been
-accessible under the `/_matrix/client/api/v1/admin`,
-`/_matrix/client/unstable/admin`, `/_matrix/client/r0/admin` and
-`/_synapse/admin` prefixes. In a future release, we will be dropping support
-for accessing Synapse's Admin API using the `/_matrix/client/*` prefixes. This
-makes it easier for homeserver admins to lock down external access to the Admin
-API endpoints.
-
-Synapse 1.20.0rc5 (2020-09-18)
-==============================
-
-In addition to the below, Synapse 1.20.0rc5 also includes the bug fix that was included in 1.19.3.

-
-
-Internal Changes
-----------------
-
-- Blacklist [MSC2753](https://github.com/matrix-org/matrix-doc/pull/2753) SyTests until it is implemented. ([\#8285](https://github.com/matrix-org/synapse/issues/8285))
-
-
-Synapse 1.19.3 (2020-09-18)
-===========================
-
-Bugfixes
---------
-
-- Partially mitigate bug where newly joined servers couldn't get past events in a room when there is a malformed event. ([\#8350](https://github.com/matrix-org/synapse/issues/8350))
-
-
-Synapse 1.20.0rc4 (2020-09-16)
-==============================
-
-Synapse 1.20.0rc4 is identical to 1.20.0rc3, with the addition of the security fix that was included in 1.19.2.
-
-
-Synapse 1.19.2 (2020-09-16)
-===========================
-
-Due to the issue below server admins are encouraged to upgrade as soon as possible.

-Bugfixes
---------
-
-- Fix a bug introduced in v1.20.0rc1 causing some features related to notifications to misbehave following the implementation of unread counts. ([\#8280](https://github.com/matrix-org/synapse/issues/8280))
-
-
-Synapse 1.20.0rc1 (2020-09-08)
-==============================
-
-Removal warning
----------------
-
-Some older clients used a [disallowed character](https://matrix.org/docs/spec/client_server/r0.6.1#post-matrix-client-r0-register-email-requesttoken) (`:`) in the `client_secret` parameter of various endpoints. The incorrect behaviour was allowed for backwards compatibility, but is now being removed from Synapse as most users have updated their client. Further context can be found at [\#6766](https://github.com/matrix-org/synapse/issues/6766).

-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/).

 ## How to contribute
 
-The preferred and easiest way to contribute changes is to fork the relevant
-project on github, and then [create a pull request](
-https://help.github.com/articles/using-pull-requests/) to ask us to pull your
-changes into our repo.
+The preferred and easiest way to contribute changes to Matrix is to fork the
+relevant project on github, and then [create a pull request](
+https://help.github.com/articles/using-pull-requests/) to ask us to pull
+your changes into our repo.
 
-Some other points to follow:
+**The single biggest thing you need to know is: please base your changes on
+the develop branch - *not* master.**
 
- * Please base your changes on the `develop` branch.
+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 follow the [code style requirements](#code-style).
+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
+please keep an eye on the pull request for feedback.
 
- * Please include a [changelog entry](#changelog) with each PR.
+To run unit tests in a local development environment, you can use:
 
- * Please [sign off](#sign-off) your contribution.
+- ``tox -e py35`` (requires tox to be installed by ``pip install tox``)
+  for SQLite-backed Synapse on Python 3.5.
+- ``tox -e py36`` for SQLite-backed Synapse on Python 3.6.
+- ``tox -e py36-postgres`` for PostgreSQL-backed Synapse on Python 3.6

 ## Code style
 
-Synapse's code style is documented [here](docs/code_style.md). Please follow
-it, including the conventions for the [sample configuration
-file](docs/code_style.md#configuration-file-format).
+All Matrix projects have a well-defined code-style - and sometimes we've even
+got as far as documenting it... For instance, synapse's code style doc lives

-Many of the conventions are enforced by scripts which are run as part of the
-[continuous integration system](#continuous-integration-and-testing). To help

-`changelog.d/1234.bugfix`, and contain content like:
+`changelog.d/1234.bugfix`, and contain content like "The security levels of
+Florbs are now validated when received over federation. Contributed by Jane
+Matrix.".

-> via the `/federation/florb` endpoint. Contributed by Jane Matrix.

-If there are multiple pull requests involved in a single bugfix/feature/etc,
-then the content for each `changelog.d` file should be the same. Towncrier will
-merge the matching files together into a single changelog entry when we come to

-
-### How do I know what to call the changelog file before I create the PR?
-
-Obviously, you don't know if you should call your newsfile
-`1234.bugfix` or `5678.bugfix` until you create the PR, which leads to a
-chicken-and-egg problem.
-
-There are two options for solving this:
-
- 1. Open the PR without a changelog file, see what number you got, and *then*
-    add the changelog file to your branch (see [Updating your pull
-    request](#updating-your-pull-request)), or:
-
- 1. Look at the [list of all
-    issues/PRs](https://github.com/matrix-org/synapse/issues?q=), add one to the
-    highest number you see, and quickly open the PR before somebody else claims
-    your number.

-    script](https://github.com/richvdh/scripts/blob/master/next_github_number.sh)

-# 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

-
-For information on how to install and use PostgreSQL, please see

-ThirdPartyEventRules breaking changes
--------------------------------------
-
-This release introduces a backwards-incompatible change to modules making use of
-``ThirdPartyEventRules`` in Synapse. If you make use of a module defined under the
-``third_party_event_rules`` config option, please make sure it is updated to handle
-the below change:
-
-The ``http_client`` argument is no longer passed to modules as they are initialised. Instead,
-modules are expected to make use of the ``http_client`` property on the ``ModuleApi`` class.
-Modules are now passed a ``module_api`` argument during initialisation, which is an instance of
-``ModuleApi``. ``ModuleApi`` instances have a ``http_client`` property which acts the same as
-the ``http_client`` argument previously passed to ``ThirdPartyEventRules`` modules.
-
-Upgrading to v1.21.0
-====================
-
-Forwarding ``/_synapse/client`` through your reverse proxy
-----------------------------------------------------------
-
-The `reverse proxy documentation
-<https://github.com/matrix-org/synapse/blob/develop/docs/reverse_proxy.md>`_ has been updated
-to include reverse proxy directives for ``/_synapse/client/*`` endpoints. As the user password
-reset flow now uses endpoints under this prefix, **you must update your reverse proxy
-configurations for user password reset to work**.
-
-Additionally, note that the `Synapse worker documentation
-<https://github.com/matrix-org/synapse/blob/develop/docs/workers.md>`_ has been updated to
- state that the ``/_synapse/client/password_reset/email/submit_token`` endpoint can be handled
-by all workers. If you make use of Synapse's worker feature, please update your reverse proxy
-configuration to reflect this change.
-
-New HTML templates
-------------------
-
-A new HTML template,
-`password_reset_confirmation.html <https://github.com/matrix-org/synapse/blob/develop/synapse/res/templates/password_reset_confirmation.html>`_,
-has been added to the ``synapse/res/templates`` directory. If you are using a
-custom template directory, you may want to copy the template over and modify it.
-
-Note that as of v1.20.0, templates do not need to be included in custom template
-directories for Synapse to start. The default templates will be used if a custom
-template cannot be found.
-
-This page will appear to the user after clicking a password reset link that has
-been emailed to them.
-
-To complete password reset, the page must include a way to make a `POST`

-custom ``sso_redirect_confirm_template_dir`` configuration then any customisations
-of the ``saml_error.html`` template will need to be merged into the ``sso_error.html``
-template. These templates are similar, but the parameters are slightly different:
-
-* The ``msg`` parameter should be renamed to ``error_description``.
-* There is no longer a ``code`` parameter for the response code.
-* A string ``error`` parameter is available that includes a short hint of why a
-  user is seeing the error page.

-Upgrading to v1.18.0
-====================
-
-Docker `-py3` suffix will be removed in future versions
--------------------------------------------------------
-
-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.
-
-Redis replication is now recommended in lieu of TCP 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 <docs/workers.md>`_ for more details.
-
-Upgrading to v1.14.0
-====================
-
-This version includes a database update which is run as part of the upgrade,
-and which may take a couple of minutes in the case of a large server. Synapse
-will not respond to HTTP requests while this update is taking place.

   * `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.

+    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.

-  not explicitly set to anything other than the return value of ``next_token`` from a previous call.
-  Defaults to ``0``.
-- ``dir``: string - Direction of event report order. Whether to fetch the most recent first (``b``) or the
-  oldest first (``f``). Defaults to ``b``.
-- ``user_id``: string - Is optional and filters to only return users with user IDs that contain this value.
-  This is the user who reported the event and wrote the reason.
-- ``room_id``: string - Is optional and filters to only return rooms with room IDs that contain this value.

-- ``event_id``: string - The ID of the reported event.
-- ``user_id``: string - This is the user who reported the event and wrote the reason.
-- ``reason``: string - Comment made by the ``user_id`` in this report. May be blank.
-- ``content``: object - Content of reported event.
-
-  - ``reason``: string - Comment made by the ``user_id`` in this report. May be blank.
-  - ``score``: integer - Content is reported based upon a negative score, where -100 is "most offensive" and 0 is "inoffensive".
-
-- ``sender``: string - This is the ID of the user who sent the original message/event that was reported.
-- ``room_alias``: string - The alias of the room. ``null`` if the room does not have a canonical alias set.
-- ``event_json``: object - Details of the original event that was reported.
-- ``next_token``: integer - Indication for pagination. See above.
