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` 36 37Known Issues 38~~~~~~~~~~~~ 39 40- There are no new known issues with this release.
