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

- Re-type hint some collections as read-only. \ 
([\#13755](https://github.com/matrix-org/synapse/issues/13755))

resync. ([\#14606](https://github.com/matrix-org/synapse/issues/14606))

state groups. ([\#14675](https://github.com/matrix-org/synapse/issues/14675))
- Add a check to ensure that locked dependencies have source distributions \ 
available. ([\#14742](https://github.com/matrix-org/synapse/issues/14742))

`/hierarchy` to clarify the condition for a room being visible. \

sending bursts of events to a local room. \ 
([\#14977](https://github.com/matrix-org/synapse/issues/14977))
- Skip calculating unread push actions in /sync when enable_push is false. \ 
([\#14980](https://github.com/matrix-org/synapse/issues/14980))

/sync responses without lazy loading of members enabled. \

([\#15070](https://github.com/matrix-org/synapse/issues/15070))
