+Synapse 1.23.0rc1 (2020-11-13)
+==============================
+
+Features
+--------
+
+- Add a push rule that highlights when a jitsi conference is created in a room. ([\#8286](https://github.com/matrix-org/synapse/issues/8286))
+- Add an admin api to delete a single file or files were not used for a defined time from server. Contributed by @dklimpel. ([\#8519](https://github.com/matrix-org/synapse/issues/8519))
+- Split admin API for reported events (`GET /_synapse/admin/v1/event_reports`) into detail and list endpoints. This is a breaking change to #8217 which was introduced in Synapse v1.21.0. Those who already use this API should check their scripts. Contributed by @dklimpel. ([\#8539](https://github.com/matrix-org/synapse/issues/8539))
+- Support generating structured logs via the standard logging configuration. ([\#8607](https://github.com/matrix-org/synapse/issues/8607), [\#8685](https://github.com/matrix-org/synapse/issues/8685))
+- Add an admin APIs to allow server admins to list users' pushers. Contributed by @dklimpel. ([\#8610](https://github.com/matrix-org/synapse/issues/8610), [\#8689](https://github.com/matrix-org/synapse/issues/8689))
+- Add an admin API `GET /_synapse/admin/v1/users/<user_id>/media` to get information about uploaded media. Contributed by @dklimpel. ([\#8647](https://github.com/matrix-org/synapse/issues/8647))
+- Add an admin API for local user media statistics. Contributed by @dklimpel. ([\#8700](https://github.com/matrix-org/synapse/issues/8700))
+- Add `displayname` to Shared-Secret Registration for admins. ([\#8722](https://github.com/matrix-org/synapse/issues/8722))
+
+
+Bugfixes
+--------
+
+- Fix fetching of E2E cross signing keys over federation when only one of the master key and device signing key is cached already. ([\#8455](https://github.com/matrix-org/synapse/issues/8455))
+- Fix a bug where Synapse would blindly forward bad responses from federation to clients when retrieving profile information. ([\#8580](https://github.com/matrix-org/synapse/issues/8580))
+- Fix a bug where the account validity endpoint would silently fail if the user ID did not have an expiration time. It now returns a 400 error. ([\#8620](https://github.com/matrix-org/synapse/issues/8620))
+- Fix email notifications for invites without local state. ([\#8627](https://github.com/matrix-org/synapse/issues/8627))
+- Fix handling of invalid group IDs to return a 400 rather than log an exception and return a 500. ([\#8628](https://github.com/matrix-org/synapse/issues/8628))
+- Fix handling of User-Agent headers that are invalid UTF-8, which caused user agents of users to not get correctly recorded. ([\#8632](https://github.com/matrix-org/synapse/issues/8632))

+- Fix bug where the `/_synapse/admin/v1/send_server_notice` API could send notices to non-notice rooms. ([\#8728](https://github.com/matrix-org/synapse/issues/8728))
+- Fix port script fails when DB has no backfilled events. Broke in v1.21.0. ([\#8729](https://github.com/matrix-org/synapse/issues/8729))
+- Fix port script to correctly handle foreign key constraints. Broke in v1.21.0. ([\#8730](https://github.com/matrix-org/synapse/issues/8730))
+- Fix port script so that it can be run again after a failure. Broke in v1.21.0. ([\#8755](https://github.com/matrix-org/synapse/issues/8755))
