- Fix a bug introduced in Synapse 1.67.0 where not specifying a config file or a server URL would lead to the `register_new_matrix_user` script failing. ([\#14637](https://github.com/matrix-org/synapse/issues/14637))
- Fix a long-standing bug where the user directory and room/user stats might be out of sync. ([\#14639](https://github.com/matrix-org/synapse/issues/14639), [\#14643](https://github.com/matrix-org/synapse/issues/14643))
- Fix a bug introduced in Synapse 1.72.0 where the background updates to add non-thread unique indexes on receipts would fail if they were previously interrupted. ([\#14650](https://github.com/matrix-org/synapse/issues/14650))
- Improve validation of field size limits in events. ([\#14664](https://github.com/matrix-org/synapse/issues/14664))
- Fix bugs introduced in Synapse 1.55.0 and 1.69.0 where application services would not be notified of events in the correct rooms, due to stale caches. ([\#14670](https://github.com/matrix-org/synapse/issues/14670))

- Add Single-Sign On setup instructions for Mastodon-based instances. ([\#14594](https://github.com/matrix-org/synapse/issues/14594))
- Change `turn_allow_guests` example value to lowercase `true`. ([\#14634](https://github.com/matrix-org/synapse/issues/14634))

Internal Changes
----------------

- Optimise push badge count calculations. Contributed by Nick @ Beeper (@fizzadar). ([\#14255](https://github.com/matrix-org/synapse/issues/14255))
- Faster remote room joins: stream the un-partial-stating of rooms over replication. ([\#14473](https://github.com/matrix-org/synapse/issues/14473), [\#14474](https://github.com/matrix-org/synapse/issues/14474))
