Notes for BIND 9.16.16 ---------------------- Feature Changes ~~~~~~~~~~~~~~~ - DNSSEC responses containing NSEC3 records with iteration counts greater than 150 are now treated as insecure. :gl:`#2445` - The maximum supported number of NSEC3 iterations that can be configured for a zone has been reduced to 150. :gl:`#2642` - The default value of the ``max-ixfr-ratio`` option was changed to ``unlimited``, for better backwards compatibility in the stable release series. :gl:`#2671` - Zones that want to transition from secure to insecure mode without becoming bogus in the process must now have their ``dnssec-policy`` changed first to ``insecure``, rather than ``none``. After the DNSSEC records have been removed from the zone, the ``dnssec-policy`` can be set to ``none`` or removed from the configuration. Setting the ``dnssec-policy`` to ``insecure`` causes CDS and CDNSKEY DELETE records to be published. :gl:`#2645` - The implementation of the ZONEMD RR type has been updated to match :rfc:`8976`. :gl:`#2658` - The ``draft-vandijk-dnsop-nsec-ttl`` IETF draft was implemented: NSEC(3) TTL values are now set to the minimum of the SOA MINIMUM value or the SOA TTL. :gl:`#2347` Bug Fixes ~~~~~~~~~ - It was possible for corrupt journal files generated by an earlier version of ``named`` to cause problems after an upgrade. This has been fixed. :gl:`#2670` - TTL values in cache dumps were reported incorrectly when ``stale-cache-enable`` was set to ``yes``. This has been fixed. :gl:`#389` :gl:`#2289` - A deadlock could occur when multiple ``rndc addzone``, ``rndc delzone``, and/or ``rndc modzone`` commands were invoked simultaneously for different zones. This has been fixed. :gl:`#2626` - ``named`` and ``named-checkconf`` did not report an error when multiple zones with the ``dnssec-policy`` option set were using the same zone file. This has been fixed. :gl:`#2603` - If ``dnssec-policy`` was active and a private key file was temporarily offline during a rekey event, ``named`` could incorrectly introduce replacement keys and break a signed zone. This has been fixed. :gl:`#2596` - When generating zone signing keys, KASP now also checks for key ID conflicts among newly created keys, rather than just between new and existing ones. :gl:`#2628` Known Issues ~~~~~~~~~~~~ - There are no new known issues with this release. See :ref:`above ` for a list of all known issues affecting this BIND 9 branch.
