+          NXDOMAIN responses to queries of type DS are now cached separately
+          from those for other types. This helps when using "grafted" zones
+          of type forward, for which the parent zone does not contain a
+          delegation, such as local top-level domains.  Previously a query
+          of type DS for such a zone could cause the zone apex to be cached
+          as NXDOMAIN, blocking all subsequent queries.  (Note: This
+          change is only helpful when DNSSEC validation is not enabled.
+          "Grafted" zones without a delegation in the parent are not a
+          recommended configuration.)
