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))
