-Synapse 1.31.0rc1 (2021-03-30)
+Synapse 1.27.0rc1 (2021-02-02)
 ==============================
 
-**Note:** As announced in v1.25.0, and in line with the deprecation policy for platform dependencies, this is the last release to support Python 3.5 and PostgreSQL 9.5. Future versions of Synapse will require Python 3.6+ and PostgreSQL 9.6+.
+Note that this release includes a change in Synapse to use Redis as a cache ─ as well as a pub/sub mechanism ─ if Redis support is enabled. No action is needed by server administrators, and we do not expect resource usage of the Redis instance to change dramatically.
 
-This is also the last release that the Synapse team will be publishing packages for Debian Stretch and Ubuntu Xenial.

-Synapse 1.30.1 (2021-03-26)
-===========================
-
-This release is identical to Synapse 1.30.0, with the exception of explicitly
-setting a minimum version of Python's Cryptography library to ensure that users
-of Synapse are protected from the recent [OpenSSL security advisories](https://mta.openssl.org/pipermail/openssl-announce/2021-March/000198.html),
-especially CVE-2021-3449.
-
-Note that Cryptography defaults to bundling its own statically linked copy of
-OpenSSL, which means that you may not be protected by your operating system's
-security updates.
-
-It's also worth noting that Cryptography no longer supports Python 3.5, so
-admins deploying to older environments may not be protected against this or
-future vulnerabilities. Synapse will be dropping support for Python 3.5 at the
-end of March.
-
-
-Updates to the Docker image
----------------------------
-
-- Ensure that the docker container has up to date versions of openssl. ([\#9697](https://github.com/matrix-org/synapse/issues/9697))
-
-
-Internal Changes
-----------------
-
-- Enforce that `cryptography` dependency is up to date to ensure it has the most recent openssl patches. ([\#9697](https://github.com/matrix-org/synapse/issues/9697))
-
-
-Synapse 1.30.0 (2021-03-22)
-===========================
-
-Note that this release deprecates the ability for appservices to
-call `POST /_matrix/client/r0/register`  without the body parameter `type`. Appservice
-developers should use a `type` value of `m.login.application_service` as
-per [the spec](https://matrix.org/docs/spec/application_service/r0.1.2#server-admin-style-permissions).
-In future releases, calling this endpoint with an access token - but without a `m.login.application_service`
-type - will fail.
-
-
-No significant changes.
-

-Synapse 1.28.0 (2021-02-25)
-===========================
-
-Note that this release drops support for ARMv7 in the official Docker images, due to repeated problems building for ARMv7 (and the associated maintenance burden this entails).
-
-This release also fixes the documentation included in v1.27.0 around the callback URI for SAML2 identity providers. If your server is configured to use single sign-on via a SAML2 IdP, you may need to make configuration changes. Please review [UPGRADE.rst](UPGRADE.rst) for more details on these changes.

-==============================
-
-Removal warning
----------------
-
-The v1 list accounts API is deprecated and will be removed in a future release.
-This API was undocumented and misleading. It can be replaced by the
-[v2 list accounts API](https://github.com/matrix-org/synapse/blob/release-v1.28.0/docs/admin_api/user_admin_api.rst#list-accounts),
-which has been available since Synapse 1.7.0 (2019-12-13).
-
-Please check if you're using any scripts which use the admin API and replace
-`GET /_synapse/admin/v1/users/<user_id>` with `GET /_synapse/admin/v2/users`.

-Synapse 1.27.0 (2021-02-16)
-===========================
-
-Note that this release includes a change in Synapse to use Redis as a cache ─ as well as a pub/sub mechanism ─ if Redis support is enabled for workers. No action is needed by server administrators, and we do not expect resource usage of the Redis instance to change dramatically.
-
-This release also changes the callback URI for OpenID Connect (OIDC) and SAML2 identity providers. If your server is configured to use single sign-on via an OIDC/OAuth2 or SAML2 IdP, you may need to make configuration changes. Please review [UPGRADE.rst](UPGRADE.rst) for more details on these changes.

+## 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).
 
-There is a growing amount of documentation located in the [docs](docs)
-directory. This documentation is intended primarily for sysadmins running their
-own Synapse instance, as well as developers interacting externally with
-Synapse. [docs/dev](docs/dev) exists primarily to house documentation for
-Synapse developers. [docs/admin_api](docs/admin_api) houses documentation
-regarding Synapse's Admin API, which is used mostly by sysadmins and external
-service developers.
+Many of the conventions are enforced by scripts which are run as part of the
+[continuous integration system](#continuous-integration-and-testing). To help
+check if you have followed the code style, you can run `scripts-dev/lint.sh`
+locally. You'll need python 3.6 or later, and to install a number of tools:
 
-If you add new files added to either of these folders, please use [GitHub-Flavoured
-Markdown](https://guides.github.com/features/mastering-markdown/).
+```
+# Install the dependencies
+pip install -e ".[lint,mypy]"
 
-Some documentation also exists in [Synapse's GitHub
-Wiki](https://github.com/matrix-org/synapse/wiki), although this is primarily
-contributed to by community authors.
-
-
-# 8. Test, test, test!
-<a name="test-test-test"></a>
-
-While you're developing and before submitting a patch, you'll
-want to test your code.
-
-## Run the linters.
-
-The linters look at your code and do two things:
-
-- ensure that your code follows the coding style adopted by the project;
-- catch a number of errors in your code.
-
-They're pretty fast, don't hesitate!
-
-```sh
-source ./env/bin/activate
+# Run the linter script
 ./scripts-dev/lint.sh
 ```
 
-Note that this script *will modify your files* to fix styling errors.
-Make sure that you have saved all your files.
+**Note that the script does not just test/check, but also reformats code, so you
+may wish to ensure any new code is committed first**.
 
-If you wish to restrict the linters to only the files changed since the last commit
-(much faster!), you can instead run:
+By default, this script checks all files and can take some time; if you alter
+only certain files, you might wish to specify paths as arguments to reduce the
+run-time:
 
-```sh
-source ./env/bin/activate
-./scripts-dev/lint.sh -d
 ```
-
-Or if you know exactly which files you wish to lint, you can instead run:
-
-```sh
-source ./env/bin/activate
 ./scripts-dev/lint.sh path/to/file1.py path/to/file2.py path/to/folder
 ```
 
-## Run the unit tests.
+You can also provide the `-d` option, which will lint the files that have been
+changed since the last git commit. This will often be significantly faster than
+linting the whole codebase.
 
-The unit tests run parts of Synapse, including your changes, to see if anything
-was broken. They are slower than the linters but will typically catch more errors.
-
-```sh
-source ./env/bin/activate
-trial tests
-```
-
-If you wish to only run *some* unit tests, you may specify
-another module instead of `tests` - or a test class or a method:
-
-```sh
-source ./env/bin/activate
-trial tests.rest.admin.test_room tests.handlers.test_admin.ExfiltrateData.test_invite
-```
-
-If your tests fail, you may wish to look at the logs:
-
-```sh
-less _trial_temp/test.log
-```
-
-## Run the integration tests.
-
-The integration tests are a more comprehensive suite of tests. They
-run a full version of Synapse, including your changes, to check if
-anything was broken. They are slower than the unit tests but will
-typically catch more errors.
-
-The following command will let you run the integration test with the most common
-configuration:
-
-```sh
-$ docker run --rm -it -v /path/where/you/have/cloned/the/repository\:/src:ro -v /path/to/where/you/want/logs\:/logs matrixdotorg/sytest-synapse:py37
-```
-
-This configuration should generally cover  your needs. For more details about other configurations, see [documentation in the SyTest repo](https://github.com/matrix-org/sytest/blob/develop/docker/README.md).

-
-# 9. Submit your patch.
-
-Once you're happy with your patch, it's time to prepare a Pull Request.
-
-To prepare a Pull Request, please:
-
-1. verify that [all the tests pass](#test-test-test), including the coding style;
-2. [sign off](#sign-off) your contribution;
-3. `git push` your commit to your fork of Synapse;
-4. on GitHub, [create the Pull Request](https://docs.github.com/en/github/collaborating-with-issues-and-pull-requests/creating-a-pull-request);
-5. add a [changelog entry](#changelog) and push it to your Pull Request;
-6. for most contributors, that's all - however, if you are a member of the organization `matrix-org`, on GitHub, please request a review from `matrix.org / Synapse Core`.
+Before pushing new changes, ensure they don't produce linting errors. Commit any

-Requirement for X-Forwarded-Proto header
-----------------------------------------
-
-When using Synapse with a reverse proxy (in particular, when using the
-`x_forwarded` option on an HTTP listener), Synapse now expects to receive an
-`X-Forwarded-Proto` header on incoming HTTP requests. If it is not set, Synapse
-will log a warning on each received request.
-
-To avoid the warning, administrators using a reverse proxy should ensure that
-the reverse proxy sets `X-Forwarded-Proto` header to `https` or `http` to
-indicate the protocol used by the client.
-
-Synapse also requires the `Host` header to be preserved.
-
-See the `reverse proxy documentation <docs/reverse_proxy.md>`_, where the
-example configurations have been updated to show how to set these headers.
-
-(Users of `Caddy <https://caddyserver.com/>`_ are unaffected, since we believe it
-sets `X-Forwarded-Proto` by default.)

+This version changes the URI used for callbacks from OAuth2 identity providers. If
+your server is configured for single sign-on via an OpenID Connect or OAuth2 identity

+to the list of permitted "redirect URIs" at the identity provider.

-  See `docs/openid.md <docs/openid.md>`_ for more information on setting up OpenID
-  Connect.
-
-* If your server is configured for single sign-on via a SAML2 identity provider, you will
-  need to add ``[synapse public baseurl]/_synapse/client/saml2/authn_response`` as a permitted
-  "ACS location" (also known as "allowed callback URLs") at the identity provider.
-
-  The "Issuer" in the "AuthnRequest" to the SAML2 identity provider is also updated to
-  ``[synapse public baseurl]/_synapse/client/saml2/metadata.xml``. If your SAML2 identity
-  provider uses this property to validate or otherwise identify Synapse, its configuration
-  will need to be updated to use the new URL. Alternatively you could create a new, separate
-  "EntityDescriptor" in your SAML2 identity provider with the new URLs and leave the URLs in
-  the existing "EntityDescriptor" as they were.
+(Note: a similar change is being made for SAML2; in this case the old URI
+``[synapse public baseurl]/_matrix/saml2`` is being deprecated, but will continue to
+work, so no immediate changes are required for existing installations.)

-**Parameters**
-
-The following parameters should be set in the URL:
-
-- ``user_id`` - Is optional and filters to only return users with user IDs
-  that contain this value. This parameter is ignored when using the ``name`` parameter.
-- ``name`` - Is optional and filters to only return users with user ID localparts
-  **or** displaynames that contain this value.
-- ``guests`` - string representing a bool - Is optional and if ``false`` will **exclude** guest users.
-  Defaults to ``true`` to include guest users.
-- ``deactivated`` - string representing a bool - Is optional and if ``true`` will **include** deactivated users.
-  Defaults to ``false`` to exclude deactivated users.
-- ``limit`` - string representing a positive integer - Is optional but is used for pagination,
-  denoting the maximum number of items to return in this call. Defaults to ``100``.
-- ``from`` - string representing a positive integer - Is optional but used for pagination,
-  denoting the offset in the returned results. This should be treated as an opaque value and
-  not explicitly set to anything other than the return value of ``next_token`` from a previous call.
-  Defaults to ``0``.
-- ``order_by`` - The method by which to sort the returned list of users.
-  If the ordered field has duplicates, the second order is always by ascending ``name``,
-  which guarantees a stable ordering. Valid values are:
-
-  - ``name`` - Users are ordered alphabetically by ``name``. This is the default.
-  - ``is_guest`` - Users are ordered by ``is_guest`` status.
-  - ``admin`` - Users are ordered by ``admin`` status.
-  - ``user_type`` - Users are ordered alphabetically by ``user_type``.
-  - ``deactivated`` - Users are ordered by ``deactivated`` status.
-  - ``shadow_banned`` - Users are ordered by ``shadow_banned`` status.
-  - ``displayname`` - Users are ordered alphabetically by ``displayname``.
-  - ``avatar_url`` - Users are ordered alphabetically by avatar URL.
-
-- ``dir`` - Direction of media order. Either ``f`` for forwards or ``b`` for backwards.
-  Setting this value to ``b`` will reverse the above sort order. Defaults to ``f``.
-
-Caution. The database only has indexes on the columns ``name`` and ``created_ts``.
-This means that if a different sort order is used (``is_guest``, ``admin``,
-``user_type``, ``deactivated``, ``shadow_banned``, ``avatar_url`` or ``displayname``),
-this can cause a large load on the database, especially for large environments.
-
-**Response**
-
-The following fields are returned in the JSON response body:
-
-- ``users`` - An array of objects, each containing information about an user.
-  User objects contain the following fields:
-
-  - ``name`` - string - Fully-qualified user ID (ex. `@user:server.com`).
-  - ``is_guest`` - bool - Status if that user is a guest account.
-  - ``admin`` - bool - Status if that user is a server administrator.
-  - ``user_type`` - string - Type of the user. Normal users are type ``None``.
-    This allows user type specific behaviour. There are also types ``support`` and ``bot``. 
-  - ``deactivated`` - bool - Status if that user has been marked as deactivated.
-  - ``shadow_banned`` - bool - Status if that user has been marked as shadow banned.
-  - ``displayname`` - string - The user's display name if they have set one.
-  - ``avatar_url`` - string -  The user's avatar URL if they have set one.
-
-- ``next_token``: string representing a positive integer - Indication for pagination. See above.
-- ``total`` - integer - Total number of media.

-Caution. The database only has indexes on the columns ``media_id``,
