new-years-eve	30a029c535	refactor: Remove pointless database restriction on key type Using a str or a [u8] as a key type is valid. There's no reason to dissallow it, even though using these values as raw key exists as an alternative.	2026-06-12 13:03:13 +00:00

new-years-eve	2e7ef60349	refactor: Use a shared helper function for submitting state events at room creation On room creation, A list of initial state events may be provided that should be submitted to the room after creation. These events should be treated as any other state event and submitted to the same checks. With this change, state events submitted on room creation will be submitted through the same helper as those through the usual endpoint. The submission helper is moved to the timeline service to make it available everywhere. This will be useful for implementing MSC4140 (issue #903).	2026-06-12 12:53:36 +00:00
