### Fixes
* A bug in the roomserver around handling rejected outliers has been fixed
* Backfilled events will now use the correct history visibility where possible
* The device list updater backoff has been fixed, which should reduce the number of outbound HTTP requests and `Failed to query device keys for some users` log entries for dead servers
* The `/sync` endpoint will no longer incorrectly return room entries for retired invites which could cause some rooms to show up in the client "Historical" section
* The `/createRoom` endpoint will now correctly populate `is_direct` in invite membership events, which may help clients to classify direct messages correctly
* The `create-account` tool will now log an error if the shared secret is not set in the Dendrite config
* A couple of minor bugs have been fixed in the membership lazy-loading
* Queued EDUs in the federation API are now cached properly
