{{% added-in this=true %}} In room versions 1 and 2, redactions were explicitly part of the authorization rules under Rule 11. As of room version 3, these conditions no longer exist as represented by this version's authorization rules.

While redactions are always accepted by the authorization rules for events, they should not be sent to clients until both the redaction event and the event the redaction affects have been received, and can be validated. If both events are valid and have been seen by the server, then the server applies the redaction if one of the following conditions is met:

  1. The power level of the redaction event's sender is greater than or equal to the redact level.
  2. The domain of the redaction event's sender matches that of the original event's sender.

If the server would apply a redaction, the redaction event is also sent to clients. Otherwise, the server simply waits for a valid partner event to arrive where it can then re-check the above.
