13a82768ac Synapse 1.13.0 (2020-05-19) 
===========================
 
 This release brings some potential changes necessary for certain
 configurations of Synapse:
 
 * If your Synapse is configured to use SSO and have a custom
   `sso_redirect_confirm_template_dir` configuration option set, you will need
   to duplicate the new `sso_auth_confirm.html`, `sso_auth_success.html` and
   `sso_account_deactivated.html` templates into that directory.
 * Synapse plugins using the `complete_sso_login` method of
   `synapse.module_api.ModuleApi` should instead switch to the async/await
   version, `complete_sso_login_async`, which includes additional checks. The
   former version is now deprecated.
 * A bug was introduced in Synapse 1.4.0 which could cause the room directory
   to be incomplete or empty if Synapse was upgraded directly from v1.2.1 or
   earlier, to versions between v1.4.0 and v1.12.x.
 
 Please review [UPGRADE.rst](https://github.com/matrix-org/synapse/blob/master/UPGRADE.rst)
 for more details on these changes and for general upgrade guidance.
 
 Notice of change to the default `git` branch for Synapse
 --------------------------------------------------------
 
 With the release of Synapse 1.13.0, the default `git` branch for Synapse has
 changed to `develop`, which is the development tip. This is more consistent with
 common practice and modern `git` usage.
 
 The `master` branch, which tracks the latest release, is still available. It is
 recommended that developers and distributors who have scripts which run builds
 using the default branch of Synapse should therefore consider pinning their
 scripts to `master`.
 
 Features
 --------
 
 - Extend the `web_client_location` option to accept an absolute URL to use as a redirect. Adds a warning when running the web client on the same hostname as homeserver. Contributed by Martin Milata. ([\#7006](https://github.com/matrix-org/synapse/issues/7006))
 - Set `Referrer-Policy` header to `no-referrer` on media downloads. ([\#7009](https://github.com/matrix-org/synapse/issues/7009))
 - Add support for running replication over Redis when using workers.

Merge tag 'v1.13.0'

Synapse 1.13.0 (2020-05-19)
===========================

This release brings some potential changes necessary for certain
configurations of Synapse:

* If your Synapse is configured to use SSO and have a custom
  `sso_redirect_confirm_template_dir` configuration option set, you will need
  to duplicate the new `sso_auth_confirm.html`, `sso_auth_success.html` and
  `sso_account_deactivated.html` templates into that directory.
* Synapse plugins using the `complete_sso_login` method of
  `synapse.module_api.ModuleApi` should instead switch to the async/await
  version, `complete_sso_login_async`, which includes additional checks. The
  former version is now deprecated.
* A bug was introduced in Synapse 1.4.0 which could cause the room directory
  to be incomplete or empty if Synapse was upgraded directly from v1.2.1 or
  earlier, to versions between v1.4.0 and v1.12.x.

Please review [UPGRADE.rst](https://github.com/matrix-org/synapse/blob/master/UPGRADE.rst)
for more details on these changes and for general upgrade guidance.

Notice of change to the default `git` branch for Synapse
--------------------------------------------------------

With the release of Synapse 1.13.0, the default `git` branch for Synapse has
changed to `develop`, which is the development tip. This is more consistent with
common practice and modern `git` usage.

The `master` branch, which tracks the latest release, is still available. It is
recommended that developers and distributors who have scripts which run builds
using the default branch of Synapse should therefore consider pinning their
scripts to `master`.

Features
--------

Stop the master relaying USER_SYNC for other workers (#7318) 
Long story short: if we're handling presence on the current worker, we shouldn't be sending USER_SYNC commands over replication.

In an attempt to figure out what is going on here, I ended up refactoring some bits of the presencehandler code, so the first 4 commits here are non-functional refactors to move this code slightly closer to sanity. (There's still plenty to do here :/). Suggest reviewing individual commits.

Fixes (I hope) #7257.

Config option to inhibit 3PID errors on /requestToken 
Adds a request_token_inhibit_errors configuration flag (disabled by
default) which, if enabled, change the behaviour of all /requestToken
endpoints so that they return a 200 and a fake sid if the 3PID was/was
not found associated with an account (depending on the endpoint),
instead of an error.

Remove usage of "conn_id" for presence. (#7128) 
* Remove `conn_id` usage for UserSyncCommand.

Each tcp replication connection is assigned a "conn_id", which is used
to give an ID to a remotely connected worker. In a redis world, there
will no longer be a one to one mapping between connection and instance,
so instead we need to replace such usages with an ID generated by the
remote instances and included in the replicaiton commands.

This really only effects UserSyncCommand.

* Add CLEAR_USER_SYNCS command that is sent on shutdown.

This should help with the case where a synchrotron gets restarted
gracefully, rather than rely on 5 minute timeout.

Clean up some LoggingContext stuff (#7120) 
* Pull Sentinel out of LoggingContext

... and drop a few unnecessary references to it

* Factor out LoggingContext.current_context

move `current_context` and `set_context` out to top-level functions.

Mostly this means that I can more easily trace what's actually referring to
LoggingContext, but I think it's generally neater.

* move copy-to-parent into `stop`

this really just makes `start` and `stop` more symetric. It also means that it
behaves correctly if you manually `set_log_context` rather than using the
context manager.

* Replace `LoggingContext.alive` with `finished`

Turn `alive` into `finished` and make it a bit better defined.

229eb81498 Synapse 1.12.0 (2020-03-23) 
===========================
 
 No significant changes since 1.12.0rc1.
 
 Debian packages and Docker images are rebuilt using the latest versions of
 dependency libraries, including Twisted 20.3.0. **Please see security advisory
 below**.
 
 Security advisory
 -----------------
 
 Synapse may be vulnerable to request-smuggling attacks when it is used with a
 reverse-proxy. The vulnerabilties are fixed in Twisted 20.3.0, and are
 described in
 [CVE-2020-10108](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2020-10108)
 and
 [CVE-2020-10109](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2020-10109).
 For a good introduction to this class of request-smuggling attacks, see
 https://portswigger.net/research/http-desync-attacks-request-smuggling-reborn.
 
 We are not aware of these vulnerabilities being exploited in the wild, and
 do not believe that they are exploitable with current versions of any reverse
 proxies. Nevertheless, we recommend that all Synapse administrators ensure that
 they have the latest versions of the Twisted library to ensure that their
 installation remains secure.
 
 * Administrators using the [`matrix.org` Docker
   image](https://hub.docker.com/r/matrixdotorg/synapse/) or the [Debian/Ubuntu
   packages from
   `matrix.org`](https://github.com/matrix-org/synapse/blob/master/INSTALL.md#matrixorg-packages)
   should ensure that they have version 1.12.0 installed: these images include
   Twisted 20.3.0.
 * Administrators who have [installed Synapse from
   source](https://github.com/matrix-org/synapse/blob/master/INSTALL.md#installing-from-source)
   should upgrade Twisted within their virtualenv by running:
   ```sh
   <path_to_virtualenv>/bin/pip install 'Twisted>=20.3.0'
   ```
 * Administrators who have installed Synapse from distribution packages should
   consult the information from their distributions.
 
 The `matrix.org` Synapse instance was not vulnerable to these vulnerabilities.
 
 Advance notice of change to the default `git` branch for Synapse
 ----------------------------------------------------------------
 
 Currently, the default `git` branch for Synapse is `master`, which tracks the
 latest release.
 
 After the release of Synapse 1.13.0, we intend to change this default to
 `develop`, which is the development tip. This is more consistent with common
 practice and modern `git` usage.
 
 Although we try to keep `develop` in a stable state, there may be occasions
 where regressions creep in. Developers and distributors who have scripts which
 run builds using the default branch of `Synapse` should therefore consider
 pinning their scripts to `master`.
 
 Synapse 1.12.0rc1 (2020-03-19)
 ==============================
 
 Features
 --------
 
 - Changes related to room alias management ([MSC2432](https://github.com/matrix-org/matrix-doc/pull/2432)):
