  * New upstream release 9.18.18 (LP: #2028413)
    - Updates:
      + Mark a primary server as temporarily unreachable when a TCP connection
        response to an SOA query times out, matching behavior of a refused TCP
        connection.
      + Mark dialup and heartbeat-interval options as deprecated.
      + Retry DNS queries without an EDNS COOKIE when the first response is
        FORMERR with the EDNS COOKIE that was sent originally.
      + Use NS records for the relaxed QNAME minimization mode to reduce the
        number of queries from named.
      + Mark TKEY mode 2 as deprecated.
      + Mark delegation-only and root-delegation-only as deprecated.
      + Run RPZ and catalog zone updates on specialized offload threads to
        reduce blocked query processing time.
    - Bug Fixes:
      + Fix assertion failure from processing already-queued queries while
        server is being reconfigured or cache is being flushed.
      + Fix failure to load zones containing resource records with a TTL value
        larger than 86400 seconds when dnssec-policy is set to insecure.
      + Fix the ability to read HMAC-MD5 key files (LP: #2015176).
      + Fix stability issues with the catalog zone implementation.
      + Fix bind9 getting stuck when listen-on statement for HTTP is removed
        from configuration.
      + Do not return delegation from cache after stale-answer-client-timeout.
      + Fix failure to auto-tune clients-per-query limit in some situations.
      + Fix proper timeouts when using max-transfer-time-in and
        max-transfer-idle-in statements.
      + Bring rndc read timeout back to 60 seconds from 30.
      + Treat libuv returning ISC_R_INVALIDPROTO as a network error.
      + Clean up empty-non-terminal NSEC3 records.
      + Fix log file rotation cleanup for absolute file path destinations.
      + Fix various catalog zone processing crashes.
      + Fix transfer hang when downloading large zones over TLS.
      + Fix named crash when adding a new zone into the configuration file for
        a name which was already configured as member zone for a catalog zone.
      + Delay DNSSEC key queries until all zones have finished loading.
