12Notes for BIND 9.18.17
13----------------------
14
15Feature Changes
16~~~~~~~~~~~~~~~
17
18- If a response from an authoritative server has its RCODE set to
19  FORMERR and contains an echoed EDNS COOKIE option that was present in
20  the query, :iscman:`named` now retries sending the query to the
21  same server without an EDNS COOKIE option. :gl:`#4049`
22
23- The ``relaxed`` QNAME minimization mode now uses NS records. This
24  reduces the number of queries :iscman:`named` makes when resolving, as
25  it allows the non-existence of NS RRsets at non-referral nodes to be
26  cached in addition to the normally cached referrals. :gl:`#3325`
27
28Bug Fixes
29~~~~~~~~~
30
31- The ability to read HMAC-MD5 key files, which was accidentally lost in
32  BIND 9.18.8, has been restored. :gl:`#3668` :gl:`#4154`
33
34- Several minor stability issues with the catalog zone implementation
35  have been fixed. :gl:`#4132` :gl:`#4136` :gl:`#4171`
