 ==============================
 Features
 --------
 - Only allow the [MSC2716](https://github.com/matrix-org/matrix-doc/pull/2716) `/batch_send?chunk_id=xxx` endpoint to connect to an already existing insertion event. ([\#10776](https://github.com/matrix-org/synapse/issues/10776))
 - Improve oEmbed URL previews by processing the author name, photo, and video information. ([\#10814](https://github.com/matrix-org/synapse/issues/10814), [\#10819](https://github.com/matrix-org/synapse/issues/10819))
 - Speed up responding with large JSON objects to requests. ([\#10868](https://github.com/matrix-org/synapse/issues/10868), [\#10905](https://github.com/matrix-org/synapse/issues/10905))
 - Add a `user_may_create_room_with_invites` spam checker callback to allow modules to allow or deny a room creation request based on the invites and/or 3PID invites it includes. ([\#10898](https://github.com/matrix-org/synapse/issues/10898))

 Internal Changes
 ----------------
 - Fix GitHub Actions config so we can run sytest on synapse from parallel branches. ([\#10659](https://github.com/matrix-org/synapse/issues/10659))
 - Split out [MSC2716](https://github.com/matrix-org/matrix-doc/pull/2716) meta events to their own fields in the `/batch_send` response. ([\#10777](https://github.com/matrix-org/synapse/issues/10777))
 - Add missing type hints to REST servlets. ([\#10785](https://github.com/matrix-org/synapse/issues/10785), [\#10817](https://github.com/matrix-org/synapse/issues/10817))
 - Simplify the internal logic which maintains the user directory database tables. ([\#10796](https://github.com/matrix-org/synapse/issues/10796))
 - Use direct references to config flags. ([\#10812](https://github.com/matrix-org/synapse/issues/10812), [\#10885](https://github.com/matrix-org/synapse/issues/10885), [\#10893](https://github.com/matrix-org/synapse/issues/10893), [\#10897](https://github.com/matrix-org/synapse/issues/10897))
 - Specify the type of token in generic "Invalid token" error messages. ([\#10815](https://github.com/matrix-org/synapse/issues/10815))
 - Make `StateFilter` frozen so it is hashable. ([\#10816](https://github.com/matrix-org/synapse/issues/10816))
 - Fix a long-standing bug where an `m.room.message` event containing a null byte would cause an internal server error. ([\#10820](https://github.com/matrix-org/synapse/issues/10820))
 - Add type hints to the state database. ([\#10823](https://github.com/matrix-org/synapse/issues/10823))
 - Opt out of cache expiry for `get_users_who_share_room_with_user`, to hopefully improve `/sync` performance when you
  haven't synced recently. ([\#10826](https://github.com/matrix-org/synapse/issues/10826))
 - Track cache eviction rates more finely in Prometheus's monitoring. ([\#10829](https://github.com/matrix-org/synapse/issues/10829))

 - Factor out PNG image data to a constant to be used in several tests. ([\#10834](https://github.com/matrix-org/synapse/issues/10834))
 - Add a test to ensure state events sent by modules get persisted correctly. ([\#10835](https://github.com/matrix-org/synapse/issues/10835))
 - Rename [MSC2716](https://github.com/matrix-org/matrix-doc/pull/2716) fields and event types from `chunk` to `batch` to match the `/batch_send` endpoint. ([\#10838](https://github.com/matrix-org/synapse/issues/10838))
 - Rename [MSC2716](https://github.com/matrix-org/matrix-doc/pull/2716) `/batch_send` query parameter from `?prev_event` to more obvious usage with `?prev_event_id`. ([\#10839](https://github.com/matrix-org/synapse/issues/10839))
 - Add type hints to `synapse.http.site`. ([\#10867](https://github.com/matrix-org/synapse/issues/10867))
 - Include outlier status when we log V2 or V3 events. ([\#10879](https://github.com/matrix-org/synapse/issues/10879))
 - Break down Grafana's cache expiry time series based on reason for eviction, c.f. [\#10829](https://github.com/matrix-org/synapse/issues/10829). ([\#10880](https://github.com/matrix-org/synapse/issues/10880))

([\#10883](https://github.com/matrix-org/synapse/issues/10883), [\#10884](https://github.com/matrix-org/synapse/issues/10884), [\#10896](https://github.com/matrix-org/synapse/issues/10896), [\#10901](https://github.com/matrix-org/synapse/issues/10901))
 - Allow the `.` and `~` characters when creating registration tokens as per the change to [MSC3231](https://github.com/matrix-org/matrix-doc/pull/3231). ([\#10887](https://github.com/matrix-org/synapse/issues/10887))
 - Clean up some unnecessary parentheses in places around the codebase. ([\#10889](https://github.com/matrix-org/synapse/issues/10889))
 - Improve type hinting in the user directory code. ([\#10891](https://github.com/matrix-org/synapse/issues/10891))
