+Synapse 1.75.0rc1 (2023-01-10)
+==============================
+
+Features
+--------
+
+- Add a `cached` function to `synapse.module_api` that returns a decorator to cache return values of functions. ([\#14663](https://github.com/matrix-org/synapse/issues/14663))
+- Add experimental support for [MSC3391](https://github.com/matrix-org/matrix-spec-proposals/pull/3391) (removing account data). ([\#14714](https://github.com/matrix-org/synapse/issues/14714))
+- Support [RFC7636](https://datatracker.ietf.org/doc/html/rfc7636) Proof Key for Code Exchange for OAuth single sign-on. ([\#14750](https://github.com/matrix-org/synapse/issues/14750))
+- Support non-OpenID compliant userinfo claims for subject and picture. ([\#14753](https://github.com/matrix-org/synapse/issues/14753))
+- Improve performance of `/sync` when filtering all rooms, message types, or senders. ([\#14786](https://github.com/matrix-org/synapse/issues/14786))
+
+
+Bugfixes
+--------
+
+- Fix the *MAU Limits* section of the Grafana dashboard relying on a specific `job` name for the workers of a Synapse deployment. ([\#14644](https://github.com/matrix-org/synapse/issues/14644))
+- Fix a bug introduced in Synapse 1.70.0 which could cause spurious `UNIQUE constraint failed` errors in the `rotate_notifs` background job. ([\#14669](https://github.com/matrix-org/synapse/issues/14669))
+- Ensure stream IDs are always updated after caches get invalidated with workers. Contributed by Nick @ Beeper (@fizzadar). ([\#14723](https://github.com/matrix-org/synapse/issues/14723))
+- Remove the unspecced `device` field from `/pushrules` responses. ([\#14727](https://github.com/matrix-org/synapse/issues/14727))
+- Fix a bug introduced in Synapse 1.73.0 where the `picture_claim` configured under `oidc_providers` was unused (the default value of `"picture"` was used instead). ([\#14751](https://github.com/matrix-org/synapse/issues/14751))
+
+
+Improved Documentation
+----------------------
+
+- Declare support for Python 3.11. ([\#14673](https://github.com/matrix-org/synapse/issues/14673))
+- Fix `target_memory_usage` being used in the description for the actual `cache_autotune` sub-option `target_cache_memory_usage`. ([\#14674](https://github.com/matrix-org/synapse/issues/14674))
+- Move `email` to Server section in config file documentation. ([\#14730](https://github.com/matrix-org/synapse/issues/14730))
+- Fix broken links in the Synapse documentation. ([\#14744](https://github.com/matrix-org/synapse/issues/14744))
+- Add missing worker settings to shared configuration documentation. ([\#14748](https://github.com/matrix-org/synapse/issues/14748))
+- Document using Twitter as a OAuth 2.0 authentication provider. ([\#14778](https://github.com/matrix-org/synapse/issues/14778))
+- Fix Synapse 1.74 upgrade notes to correctly explain how to install pyICU when installing Synapse from PyPI. ([\#14797](https://github.com/matrix-org/synapse/issues/14797))
+- Update link to towncrier in contribution guide. ([\#14801](https://github.com/matrix-org/synapse/issues/14801))
+
+
+Internal Changes
+----------------
+
+- Improve performance of the `/hierarchy` endpoint. ([\#14263](https://github.com/matrix-org/synapse/issues/14263))
+- Faster remote room joins: stream the un-partial-stating of events over replication. ([\#14545](https://github.com/matrix-org/synapse/issues/14545), [\#14546](https://github.com/matrix-org/synapse/issues/14546))

+- Change `handle_new_client_event` signature so that a 429 does not reach clients on `PartialStateConflictError`, and internally retry when needed instead. ([\#14665](https://github.com/matrix-org/synapse/issues/14665))
+- Remove dependency on jQuery on reCAPTCHA page. ([\#14672](https://github.com/matrix-org/synapse/issues/14672))
