New Features
~~~~~~~~~~~~
- New ``rndc`` command ``rndc dnssec -checkds`` to tell ``named``
that a DS record for a given zone or key has been published or withdrawn
from the parent. Replaces the time-based ``parent-registration-delay``
configuration option. [GL #1613]
- Add a new ``rndc`` command, ``rndc dnssec -checkds``, which signals to
``named`` that a DS record for a given zone or key has been published
or withdrawn from the parent. This command replaces the time-based
``parent-registration-delay`` configuration option. [GL #1613]
- Log when ``named`` adds a CDS/CDNSKEY to the zone. [GL #1748]

Feature Changes
~~~~~~~~~~~~~~~
- Previously, using ``dig +bufsize=0`` had the side effect of disabling EDNS,
and there was no way to test the remote server's behavior when it had received
a packet with EDNS0 buffer size set to ``0``. This is no longer the case;
``dig +bufsize=0`` now sends a DNS message with EDNS version 0 and buffer size
set to ``0``. To disable EDNS, use ``dig +noedns``. [GL #2054]

- In rare circumstances, named would exit with assertion failure when the number
of nodes stored in the red-black-tree exceeds the maximum allowed size of the
internal hashtable. [GL #2104]

- Silence spurious system log messages for EPROTO(71) error code that has been
seen on older operating systems where unhandled ICMPv6 errors result in a
generic protocol error being returned instead of the more specific error code.

- With query minimization enabled, named failed to resolve ip6.arpa. names
that had more labels before the IPv6 part. For example, when named
implemented query minimization on a name like
``A.B.1.2.3.4.(...).ip6.arpa.``, it stopped at the left-most IPv6 label, i.e.
``1.2.3.4.(...).ip6.arpa.`` without considering the extra labels ``A.B``.
That caused a query loop when resolving the name: if named received
NXDOMAIN answers, then the same query was repeatedly sent until the number
of queries sent reached the value in the ``max-recursion-queries``
configuration option. [GL #1847]
