chat/matrix-synapse: Update to 1.69.0

Synapse 1.69.0 (2022-10-17)
===========================

Please note that legacy Prometheus metric names are now deprecated and will be removed in Synapse 1.73.0.
Server administrators should update their dashboards and alerting rules to avoid using the deprecated metric names.
See the [upgrade notes](https://matrix-org.github.io/synapse/v1.69/upgrade.html#upgrading-to-v1690) for more details.

Deprecations and Removals
-------------------------

- Remove the `complete_sso_login` method from the Module API which was
  deprecated in Synapse
  1.13.0. ([\#13843](https://github.com/matrix-org/synapse/issues/13843))

- Announce that legacy metric names are deprecated, will be turned off
  by default in Synapse v1.71.0 and removed altogether in Synapse
  v1.73.0. See the upgrade notes for more
  information. ([\#14024](https://github.com/matrix-org/synapse/issues/14024))

- Deprecate the `generate_short_term_login_token` method in favor of
  an async `create_login_token` method in the Module
  API. ([\#13842](https://github.com/matrix-org/synapse/issues/13842))

Features
--------

- Allow application services to set the `origin_server_ts` of a state
  event by providing the query parameter `ts` in [`PUT
  /_matrix/client/r0/rooms/{roomId}/state/{eventType}/{stateKey}`](https://spec.matrix.org/v1.4/client-server-api/#put_matrixclientv3roomsroomidstateeventtypestatekey),
  per
  [MSC3316](https://github.com/matrix-org/matrix-doc/pull/3316). Contributed
  by
  @lukasdenk. ([\#11866](https://github.com/matrix-org/synapse/issues/11866))

- Allow server admins to require a manual approval process before new
  accounts can be used (using
  [MSC3866](https://github.com/matrix-org/matrix-spec-proposals/pull/3866)). ([\#13556](https://github.com/matrix-org/synapse/issues/13556))

- Exponentially backoff from backfilling the same event over and
  over. ([\#13635](https://github.com/matrix-org/synapse/issues/13635),
  [\#13936](https://github.com/matrix-org/synapse/issues/13936))

- Add cache invalidation across workers to module
  API. ([\#13667](https://github.com/matrix-org/synapse/issues/13667),
  [\#13947](https://github.com/matrix-org/synapse/issues/13947))

- Experimental implementation of
  [MSC3882](https://github.com/matrix-org/matrix-spec-proposals/pull/3882)
  to allow an existing device/session to generate a login token for
  use on a new
  device/session. ([\#13722](https://github.com/matrix-org/synapse/issues/13722),
  [\#13868](https://github.com/matrix-org/synapse/issues/13868))

- Experimental support for thread-specific receipts
  ([MSC3771](https://github.com/matrix-org/matrix-spec-proposals/pull/3771)). ([\#13782](https://github.com/matrix-org/synapse/issues/13782),
  [\#13893](https://github.com/matrix-org/synapse/issues/13893),
  [\#13932](https://github.com/matrix-org/synapse/issues/13932),
  [\#13937](https://github.com/matrix-org/synapse/issues/13937),
  [\#13939](https://github.com/matrix-org/synapse/issues/13939))

- Add experimental support for [MSC3881: Remotely toggle push
  notifications for another
  client](https://github.com/matrix-org/matrix-spec-proposals/pull/3881). ([\#13799](https://github.com/matrix-org/synapse/issues/13799),
  [\#13831](https://github.com/matrix-org/synapse/issues/13831),
  [\#13860](https://github.com/matrix-org/synapse/issues/13860))

- Keep track when an event pulled over federation fails its signature
  check so we can intelligently back-off in the
  future. ([\#13815](https://github.com/matrix-org/synapse/issues/13815))

- Improve validation for the unspecced, internal-only
  `_matrix/client/unstable/add_threepid/msisdn/submit_token`
  endpoint. ([\#13832](https://github.com/matrix-org/synapse/issues/13832))

- Faster remote room joins: record _when_ we first partial-join to a
  room. ([\#13892](https://github.com/matrix-org/synapse/issues/13892))

- Support a `dir` parameter on the `/relations` endpoint per
  [MSC3715](https://github.com/matrix-org/matrix-doc/pull/3715). ([\#13920](https://github.com/matrix-org/synapse/issues/13920))

- Ask mail servers receiving emails from Synapse to not send automatic
  replies (e.g. out-of-office
  responses). ([\#13957](https://github.com/matrix-org/synapse/issues/13957))
