Notification rules can be restricted to specific sites via the "Sites" filter, found under "General filters" when filtering for hosts and services.

Since Checkmk 2.4.0 this filter only offered sites that have configuration replication ("push configuration to this site") enabled. In distributed setups where remote sites are connected only through a notification spooler, and therefore do not use configuration replication, those sites could no longer be selected. This effectively made the site filter unusable for such setups.

Before Checkmk 2.4.0 the "Sites" filter offered all configured sites, regardless of whether configuration replication was enabled.

The filter now offers all configured sites again, restoring the previous behavior.
