Notes for BIND 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, :iscman:`named` now retries sending the query to the
same server without an EDNS COOKIE option. :gl:`#4049`
- The ``relaxed`` QNAME minimization mode now uses NS records. This
reduces the number of queries :iscman:`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. :gl:`#3325`
Bug Fixes
~~~~~~~~~
- The ability to read HMAC-MD5 key files, which was accidentally lost in
BIND 9.18.8, has been restored. :gl:`#3668` :gl:`#4154`
- Several minor stability issues with the catalog zone implementation
have been fixed. :gl:`#4132` :gl:`#4136` :gl:`#4171`
Known Issues
~~~~~~~~~~~~
- There are no new known issues with this release. See :ref:`above
<relnotes_known_issues>` for a list of all known issues affecting this
BIND 9 branch.
