"Notes for BIND 9.20.13
New Features

    Add a new option manual-mode to dnssec-policy.

    When enabled, named will not modify DNSSEC keys or key states
    automatically. The proposed change will be logged and only after manual
    confirmation with rndc dnssec -step will the modification be made. [GL
    #4606]

    Add a new option servfail-until-ready to response-policy zones.

    By default, when named is started, it starts answering queries before
    all response policy zones are completely loaded and processed. This new
    option instructs named to respond with SERVFAIL until all the response
    policy zones are processed and ready. Note that if one or more response
    policy zones fail to load, named starts responding to queries according
    to those zones that did load.

    Note, that enabling this option has no effect when a DNS Response
    Policy Service (DNSRPS) interface is used. [GL #5222]

    Support for parsing HHIT and BRID records has been added.

    [GL #5444]

Removed Features

    Deprecate the tkey-gssapi-credential statement.

    The tkey-gssapi-keytab statement allows GSS-TSIG to be set up in a
    simpler and more reliable way than using the tkey-gssapi-credential
    statement and setting environment variables (e.g. KRB5_KTNAME).
    Therefore, the tkey-gssapi-credential statement has been deprecated;
    tkey-gssapi-keytab should be used instead.

    For configurations currently using a combination of both
    tkey-gssapi-keytab and tkey-gssapi-credential, the latter should be
    dropped and the keytab pointed to by tkey-gssapi-keytab should now only
    contain the credential previously specified by tkey-gssapi-credential.
    [GL #4204]

    Obsolete the “tkey-domain” statement.

    Mark the tkey-domain statement as obsolete because it has not had any
    effect on server behavior since support for TKEY Mode 2
    (Diffie-Hellman) was removed (in BIND 9.20.0). [GL #4204]

Bug Fixes

    Prevent spurious SERVFAILs for certain 0-TTL resource records.

    Under certain circumstances, BIND 9 can return SERVFAIL when updating
    existing entries in the cache with new NS, A, AAAA, or DS records that
    have a TTL of zero. [GL #5294]

    Fix unexpected termination if catalog-zones had undefined
    default-primaries.

    The issue manifested only if the server was reloaded or reconfigured
    twice. [GL #5494]"
