 Features
 --------
 
-- Add support for MSC3202: sending one-time key counts and fallback key usage states to Application Services. ([\#11617](https://github.com/matrix-org/synapse/issues/11617))
+- Add support for [MSC3202](https://github.com/matrix-org/matrix-doc/pull/3202): sending one-time key counts and fallback key usage states to Application Services. ([\#11617](https://github.com/matrix-org/synapse/issues/11617))
 - Make a `POST` to `/rooms/<room_id>/receipt/m.read/<event_id>` only trigger a push notification if the count of unread messages is different to the one in the last successfully sent push. ([\#11835](https://github.com/matrix-org/synapse/issues/11835))
 - Fetch images when previewing Twitter URLs. Contributed by @AndrewRyanChama. ([\#11985](https://github.com/matrix-org/synapse/issues/11985))
 - Track cache invalidations in Prometheus metrics, as already happens for cache eviction based on size or time. ([\#12000](https://github.com/matrix-org/synapse/issues/12000))

 - Fix a bug introduced in Synapse v1.48.0 where an edit of the latest event in a thread would not be properly applied to the thread summary. ([\#11992](https://github.com/matrix-org/synapse/issues/11992))
 - Fix long standing bug where `get_rooms_for_user` was not correctly invalidated for remote users when the server left a room. ([\#11999](https://github.com/matrix-org/synapse/issues/11999))
-- Fix 500 error with Postgres when looking backwards with the [MSC3030](https://github.com/matrix-org/matrix-doc/pull/3030) `/timestamp_to_event?dir=b` endpoint. ([\#12024](https://github.com/matrix-org/synapse/issues/12024))

-- Properly fix a long-standing bug where wrong data could be inserted in the `event_search` table when using sqlite. This could block running `synapse_port_db` with an "argument of type 'int' is not iterable" error. This bug was partially fixed by a change in Synapse 1.44.0.

 - Fix slow performance of `/logout` in some cases where refresh tokens are in use. The slowness existed since the initial implementation of refresh tokens. ([\#12056](https://github.com/matrix-org/synapse/issues/12056))
 - Fix a long-standing bug where Synapse would make additional failing requests over federation for missing data. ([\#12077](https://github.com/matrix-org/synapse/issues/12077))
 - Fix occasional 'Unhandled error in Deferred' error message. ([\#12089](https://github.com/matrix-org/synapse/issues/12089))
