- Update to release 9.18.17
Feature Changes:
* If a response from an authoritative server has its RCODE set to
FORMERR and contains an echoed EDNS COOKIE option that was
present in the query, named now retries sending the query to
the same server without an EDNS COOKIE option.
* The relaxed QNAME minimization mode now uses NS records. This
reduces the number of queries named makes when resolving, as it
allows the non-existence of NS RRsets at non-referral nodes to
be cached in addition to the normally cached referrals.
Bug Fixes:
* The ability to read HMAC-MD5 key files, which was accidentally
lost in BIND 9.18.8, has been restored.
* Several minor stability issues with the catalog zone
implementation have been fixed.
