BIND 9.9 includes a number of changes from BIND 9.8 and earlier
releases.  New features include:

        - NXDOMAIN redirection.
        - Improved scalability from using multiple threads to
          listen for queries.
        - New 'rndc flushtree' command clears all data under a
          given name from the DNS cache.
        - New 'rndc sync' command dumps pending changes in a
          dynamic zone to disk without a freeze/thaw cycle.
        - The 'also-notify' option now takes the same syntax as
          'masters', so it can used named masterlists and TSIG
        - 'auto-dnssec' zones can now have NSEC3 parameters set
          prior to signing.
        - 'dnssec-signzone -D' writes an output file containing
          only DNSSEC data, which can be included by the primary
          zone file.
        - 'dnssec-signzone -R' forces removal of signatures that
          are not expired but were created by a key which no longer
        - 'dnssec-signzone -X' allows a separate expiration date to
          be specified for DNSKEY signatures from other signatures.
        - New '-L' option to dnssec-keygen, dnssec-settime, and
          dnssec-keyfromlabel sets the default TTL for the key.
        - dnssec-dsfromkey now supports reading from standard
          input, to make it easier to convert DNSKEY to DS.
        - RFC 1918 reverse zones have been added to the empty-zones
          table per RFC 6303.
        - Dynamic updates can now optionally set the zone's SOA
          serial number to the current UNIX time.
