Bugfixes
--------

- Fix a longstanding bug where invalid ignored users in account data could break clients. ([\#8454](https://github.com/matrix-org/synapse/issues/8454))
- Fix a bug where backfilling a room with an event that was missing the `redacts` field would break. ([\#8457](https://github.com/matrix-org/synapse/issues/8457))
- Don't attempt to respond to some requests if the client has already disconnected. ([\#8465](https://github.com/matrix-org/synapse/issues/8465))

- Expose the `uk.half-shot.msc2778.login.application_service` to clients from the login API. This feature was added in v1.21.0, but was not exposed as a potential login flow. ([\#8504](https://github.com/matrix-org/synapse/issues/8504))
- Fix error code for `/profile/{userId}/displayname` to be `M_BAD_JSON`. ([\#8517](https://github.com/matrix-org/synapse/issues/8517))
- Fix a bug introduced in v1.7.0 that could cause Synapse to insert values from non-state `m.room.retention` events into the `room_retention` database table. ([\#8527](https://github.com/matrix-org/synapse/issues/8527))
- Fix not sending events over federation when using sharded event writers. ([\#8536](https://github.com/matrix-org/synapse/issues/8536))
- Fix a long standing bug where email notifications for encrypted messages were blank. ([\#8545](https://github.com/matrix-org/synapse/issues/8545))
- Fix increase in the number of `There was no active span...` errors logged when using OpenTracing. ([\#8567](https://github.com/matrix-org/synapse/issues/8567))
- Fix a bug that prevented errors encountered during execution of the `synapse_port_db` from being correctly printed. ([\#8585](https://github.com/matrix-org/synapse/issues/8585))
- Fix appservice transactions to only include a maximum of 100 persistent and 100 ephemeral events. ([\#8606](https://github.com/matrix-org/synapse/issues/8606))
