There was a problem hiding this comment.
To check: in a worker deployment, the main process has config.worker.worker_app set to None?
I'm worried that there might be danger in having the main process run some remote-join-aware code, while others are expecting full-join-only. But maybe there isn't an easy way round this?

Yeah, this condition will never be hit I don't think, as synapse.app.homeserver is the entry point for master only.

I don't think this is an issue as long as we refuse to start up workers, as the only real difference between monolith and worker mode is if there are other workers running.

Synapse 1.66.0rc1 (2022-08-23) ============================== This release removes the ability for homeservers to delegate email ownership verification and password reset confirmation to identity servers. This removal was originally planned for Synapse 1.64, but was later deferred until now. See the [upgrade notes](https://matrix-org.github.io/synapse/v1.66/upgrade.html#upgrading-to-v1660) for more details. Features -------- - Improve validation of request bodies for the following client-server API endpoints: [`/account/password`](https://spec.matrix.org/v1.3/client-server-api/#post_matrixclientv3accountpassword), [`/account/password/email/requestToken`](https://spec.matrix.org/v1.3/client-server-api/#post_matrixclientv3accountpasswordemailrequesttoken), [`/account/deactivate`](https://spec.matrix.org/v1.3/client-server-api/#post_matrixclientv3accountdeactivate) and [`/account/3pid/email/requestToken`](https://spec.matrix.org/v1.3/client-server-api/#post_matrixclientv3account3pidemailrequesttoken). ([\#13188](#13188), [\#13563](#13563)) - Add forgotten status to [Room Details Admin API](https://matrix-org.github.io/synapse/latest/admin_api/rooms.html#room-details-api). ([\#13503](#13503)) - Add an experimental implementation for [MSC3852 (Expose user agents on `Device`)](matrix-org/matrix-spec-proposals#3852). ([\#13549](#13549)) - Add `org.matrix.msc2716v4` experimental room version with updated content fields. Part of [MSC2716 (Importing history)](matrix-org/matrix-spec-proposals#2716). ([\#13551](#13551)) - Add support for compression to federation responses. ([\#13537](#13537)) - Improve performance of sending messages in rooms with thousands of local users. ([\#13522](#13522), [\#13547](#13547)) Bugfixes -------- - Faster room joins: make `/joined_members` block whilst the room is partial stated. ([\#13514](#13514)) - Fix a bug introduced in Synapse 1.21.0 where the [`/event_reports` Admin API](https://matrix-org.github.io/synapse/develop/admin_api/event_reports.html) could return a total count which was larger than the number of results you can actually query for. ([\#13525](#13525)) - Fix a bug introduced in Synapse 1.52.0 where sending server notices fails if `max_avatar_size` or `allowed_avatar_mimetypes` is set and not `system_mxid_avatar_url`. ([\#13566](#13566)) - Fix a bug where the `opentracing.force_tracing_for_users` config option would not apply to [`/sendToDevice`](https://spec.matrix.org/v1.3/client-server-api/#put_matrixclientv3sendtodeviceeventtypetxnid) and [`/keys/upload`](https://spec.matrix.org/v1.3/client-server-api/#post_matrixclientv3keysupload) requests. ([\#13574](#13574)) Improved Documentation ---------------------- - Add `openssl` example for generating registration HMAC digest. ([\#13472](#13472)) - Tidy up Synapse's README. ([\#13491](#13491)) - Document that event purging related to the `redaction_retention_period` config option is executed only every 5 minutes. ([\#13492](#13492)) - Add a warning to retention documentation regarding the possibility of database corruption. ([\#13497](#13497)) - Document that the `DOCKER_BUILDKIT=1` flag is needed to build the docker image. ([\#13515](#13515)) - Add missing links in `user_consent` section of configuration manual. ([\#13536](#13536)) - Fix the doc and some warnings that were referring to the nonexistent `custom_templates_directory` setting (instead of `custom_template_directory`). ([\#13538](#13538)) Deprecations and Removals ------------------------- - Remove the ability for homeservers to delegate email ownership verification and password reset confirmation to identity servers. See [upgrade notes](https://matrix-org.github.io/synapse/v1.66/upgrade.html#upgrading-to-v1660) for more details. Internal Changes ---------------- - Update the rejected state of events during de-partial-stating. ([\#13459](#13459)) - Avoid blocking lazy-loading `/sync`s during partial joins due to remote memberships. Pull remote memberships from auth events instead of the room state. ([\#13477](#13477)) - Refuse to start when faster joins is enabled on a deployment with workers, since worker configurations are not currently supported. ([\#13531](#13531)) - Allow use of both `@trace` and `@tag_args` stacked on the same function. ([\#13453](#13453)) - Instrument the federation/backfill part of `/messages` for understandable traces in Jaeger. ([\#13489](#13489)) - Instrument `FederationStateIdsServlet` (`/state_ids`) for understandable traces in Jaeger. ([\#13499](#13499), [\#13554](#13554)) - Track HTTP response times over 10 seconds from `/messages` (`synapse_room_message_list_rest_servlet_response_time_seconds`). ([\#13533](#13533)) - Add metrics to track how the rate limiter is affecting requests (sleep/reject). ([\#13534](#13534), [\#13541](#13541)) - Add metrics to time how long it takes us to do backfill processing (`synapse_federation_backfill_processing_before_time_seconds`, `synapse_federation_backfill_processing_after_time_seconds`). ([\#13535](#13535), [\#13584](#13584)) - Add metrics to track rate limiter queue timing (`synapse_rate_limit_queue_wait_time_seconds`). ([\#13544](#13544)) - Update metrics to track `/messages` response time by room size. ([\#13545](#13545)) - Refactor methods in `synapse.api.auth.Auth` to use `Requester` objects everywhere instead of user IDs. ([\#13024](#13024)) - Clean-up tests for notifications. ([\#13471](#13471)) - Add some miscellaneous comments to document sync, especially around `compute_state_delta`. ([\#13474](#13474)) - Use literals in place of `HTTPStatus` constants in tests. ([\#13479](#13479), [\#13488](#13488)) - Add comments about how event push actions are rotated. ([\#13485](#13485)) - Modify HTML template content to better support mobile devices' screen sizes.

Synapse 1.66.0 (2022-08-31) =========================== No significant changes since 1.66.0rc2. This release removes the ability for homeservers to delegate email ownership verification and password reset confirmation to identity servers. This removal was originally planned for Synapse 1.64, but was later deferred until now. See the [upgrade notes](https://matrix-org.github.io/synapse/v1.66/upgrade.html#upgrading-to-v1660) for more details. Deployments with multiple workers should note that the direct TCP replication configuration was deprecated in Synapse v1.18.0 and will be removed in Synapse v1.67.0. In particular, the TCP `replication` [listener](https://matrix-org.github.io/synapse/v1.66/usage/configuration/config_documentation.html#listeners) type (not to be confused with the `replication` resource on the `http` listener type) and the `worker_replication_port` config option will be removed . To migrate to Redis, add the [`redis` config](https://matrix-org.github.io/synapse/v1.66/workers.html#shared-configuration), then remove the TCP `replication` listener from config of the master and `worker_replication_port` from worker config. Note that a HTTP listener with a `replication` resource is still required. See the [worker documentation](https://matrix-org.github.io/synapse/v1.66/workers.html) for more details. Synapse 1.66.0rc2 (2022-08-30) ============================== Bugfixes -------- - Fix a bug introduced in Synapse 1.66.0rc1 where the new rate limit metrics were misreported (`synapse_rate_limit_sleep_affected_hosts`, `synapse_rate_limit_reject_affected_hosts`). ([\matrix-org#13649](matrix-org#13649)) Synapse 1.66.0rc1 (2022-08-23) ============================== Features -------- - Improve validation of request bodies for the following client-server API endpoints: [`/account/password`](https://spec.matrix.org/v1.3/client-server-api/#post_matrixclientv3accountpassword), [`/account/password/email/requestToken`](https://spec.matrix.org/v1.3/client-server-api/#post_matrixclientv3accountpasswordemailrequesttoken), [`/account/deactivate`](https://spec.matrix.org/v1.3/client-server-api/#post_matrixclientv3accountdeactivate) and [`/account/3pid/email/requestToken`](https://spec.matrix.org/v1.3/client-server-api/#post_matrixclientv3account3pidemailrequesttoken).
