lil fix

We can follow-up this PR with:

 1. Only try to backfill from an event if we haven't tried recently -> https://github.com/matrix-org/synapse/issues/13622
 1. When we decide to backfill that event again, process it in the background so it doesn't block and make `/messages` slow when we know it will probably fail again -> https://github.com/matrix-org/synapse/issues/13623
 1. Generally track failures everywhere we try and fail to pull an event over federation -> https://github.com/matrix-org/synapse/issues/13700

Fix https://github.com/matrix-org/synapse/issues/13621

+Synapse 1.67.0 (2022-09-13)
+===========================
+
+This release removes using the deprecated direct TCP replication configuration
+for workers. Server admins should use Redis instead. See the [upgrade
+notes](https://matrix-org.github.io/synapse/v1.67/upgrade.html#upgrading-to-v1670).
+
+The minimum version of `poetry` supported for managing source checkouts is now
+1.2.0.
+
+**Notice:** from the next major release (1.68.0) installing Synapse from a source
+checkout will require a recent Rust compiler. Those using packages or
+`pip install matrix-synapse` will not be affected. See the [upgrade
+notes](https://matrix-org.github.io/synapse/v1.67/upgrade.html#upgrading-to-v1670).
+
+**Notice:** from the next major release (1.68.0), running Synapse with a SQLite
+database will require SQLite version 3.27.0 or higher. (The [current minimum
+ version is SQLite 3.22.0](https://github.com/matrix-org/synapse/blob/release-v1.67/synapse/storage/engines/sqlite.py#L69-L78).)
+See [#12983](https://github.com/matrix-org/synapse/issues/12983) and the [upgrade notes](https://matrix-org.github.io/synapse/v1.67/upgrade.html#upgrading-to-v1670) for more details.
+
+
+No significant changes since 1.67.0rc1.
+
+
+Synapse 1.67.0rc1 (2022-09-06)
+==============================
+
+Features
+--------
+
+- Support setting the registration shared secret in a file, via a new `registration_shared_secret_path` configuration option. ([\#13614](https://github.com/matrix-org/synapse/issues/13614))
+- Change the default startup behaviour so that any missing "additional" configuration files (signing key, etc) are generated automatically. ([\#13615](https://github.com/matrix-org/synapse/issues/13615))
+- Improve performance of sending messages in rooms with thousands of local users. ([\#13634](https://github.com/matrix-org/synapse/issues/13634))
+
+
+Bugfixes
+--------
+
+- Fix a bug introduced in Synapse 1.13 where the [List Rooms admin API](https://matrix-org.github.io/synapse/develop/admin_api/rooms.html#list-room-api) would return integers instead of booleans for the `federatable` and `public` fields when using a Sqlite database. ([\#13509](https://github.com/matrix-org/synapse/issues/13509))
+- Fix bug that user cannot `/forget` rooms after the last member has left the room. ([\#13546](https://github.com/matrix-org/synapse/issues/13546))
+- Faster Room Joins: fix `/make_knock` blocking indefinitely when the room in question is a partial-stated room. ([\#13583](https://github.com/matrix-org/synapse/issues/13583))
+- Fix loading the current stream position behind the actual position. ([\#13585](https://github.com/matrix-org/synapse/issues/13585))
+- Fix a longstanding bug in `register_new_matrix_user` which meant it was always necessary to explicitly give a server URL. ([\#13616](https://github.com/matrix-org/synapse/issues/13616))
+- Fix the running of [MSC1763](https://github.com/matrix-org/matrix-spec-proposals/pull/1763) retention purge_jobs in deployments with background jobs running on a worker by forcing them back onto the main worker. Contributed by Brad @ Beeper. ([\#13632](https://github.com/matrix-org/synapse/issues/13632))
+- Fix a long-standing bug that downloaded media for URL previews was not deleted while database background updates were running. ([\#13657](https://github.com/matrix-org/synapse/issues/13657))
+- Fix [MSC3030](https://github.com/matrix-org/matrix-spec-proposals/pull/3030) `/timestamp_to_event` endpoint to return the correct next event when the events have the same timestamp. ([\#13658](https://github.com/matrix-org/synapse/issues/13658))
+- Fix bug where we wedge media plugins if clients disconnect early. Introduced in v1.22.0. ([\#13660](https://github.com/matrix-org/synapse/issues/13660))
+- Fix a long-standing bug which meant that keys for unwhitelisted servers were not returned by `/_matrix/key/v2/query`. ([\#13683](https://github.com/matrix-org/synapse/issues/13683))
+- Fix a bug introduced in Synapse v1.20.0 that would cause the unstable unread counts from [MSC2654](https://github.com/matrix-org/matrix-spec-proposals/pull/2654) to be calculated even if the feature is disabled. ([\#13694](https://github.com/matrix-org/synapse/issues/13694))
+
+
+Updates to the Docker image
+---------------------------
+
+- Update docker image to use a stable version of poetry. ([\#13688](https://github.com/matrix-org/synapse/issues/13688))
+
+
+Improved Documentation
+----------------------
+
+- Improve the description of the ["chain cover index"](https://matrix-org.github.io/synapse/latest/auth_chain_difference_algorithm.html) used internally by Synapse. ([\#13602](https://github.com/matrix-org/synapse/issues/13602))
+- Document how ["monthly active users"](https://matrix-org.github.io/synapse/latest/usage/administration/monthly_active_users.html) is calculated and used. ([\#13617](https://github.com/matrix-org/synapse/issues/13617))
+- Improve documentation around user registration. ([\#13640](https://github.com/matrix-org/synapse/issues/13640))
+- Remove documentation of legacy `frontend_proxy` worker app. ([\#13645](https://github.com/matrix-org/synapse/issues/13645))
+- Clarify documentation that HTTP replication traffic can be protected with a shared secret. ([\#13656](https://github.com/matrix-org/synapse/issues/13656))
+- Remove unintentional colons from [config manual](https://matrix-org.github.io/synapse/latest/usage/configuration/config_documentation.html) headers. ([\#13665](https://github.com/matrix-org/synapse/issues/13665))
+- Update docs to make enabling metrics more clear. ([\#13678](https://github.com/matrix-org/synapse/issues/13678))
+- Clarify `(room_id, event_id)` global uniqueness and how we should scope our database schemas. ([\#13701](https://github.com/matrix-org/synapse/issues/13701))

+- Drop support for calling `/_matrix/client/v3/rooms/{roomId}/invite` without an `id_access_token`, which was not permitted by the spec. Contributed by @Vetchu. ([\#13241](https://github.com/matrix-org/synapse/issues/13241))
