        BIND 9.11.0 includes a number of changes from BIND 9.10 and earlier
        releases.  New features include:
 
+       - SERVFAIL responses can now be cached for a limited time
+         (defaulting to 10 seconds, with an upper limit of 30).
+         This can reduce the frequency of retries when a query is
+         persistently failing.
+       - The new "rndc nta" command can be used to set a "negative
+         trust anchor", disabling DNSSEC validation for a specific
+         domain; this can be used when responses from a domain are
+         known to be failing validation due to administrative error
+         rather than because of a spoofing attack. Negative trust
+         anchors are strictly temporary; by default they expire after
+         one hour, but can be configured to last up to one week.
+       - Update forwarding performance has been improved by allowing
+         a single TCP connection to be shared by multiple updates.
        - The EDNS Client Subnet (ECS) option is now supported for
          authoritative servers; if a query contains an ECS option
          then ACLs containing "geoip" or "ecs" elements can match
