+Notes for BIND 9.18.39
+----------------------
+
+New Features
+~~~~~~~~~~~~
+
+- Support for parsing the DSYNC record has been added.
+
+  :gl:`#5440`
+
+Feature Changes
+~~~~~~~~~~~~~~~
+
+- Add deprecation warnings for RSASHA1, RSASHA1-NSEC3SHA1 and DS digest
+  type 1.
+
+  RSASHA1 and RSASHA1-NSEC-SHA1 DNSKEY algorithms have been deprecated
+  by the IETF and should no longer be used for DNSSEC. DS digest type 1
+  (SHA1) has also been deprecated. Validators are now expected to treat
+  these algorithms and digest as unknown, resulting in some zones being
+  treated as insecure when they were previously treated as secure.
+  Warnings have been added to named and tools when these algorithms and
+  this digest are being used for signing.
+
+  Zones signed with RSASHA1 or RSASHA1-NSEC-SHA1 should be migrated to a
+  different DNSKEY algorithm.
+
+  Zones with DS or CDS records with digest type 1 (SHA1) should be
+  updated to use a different digest type (e.g. SHA256) and the digest
+  type 1 records should be removed.
+
+  Related to #5358
+
+Bug Fixes
+~~~~~~~~~
+
+- Clean enough memory when adding new ADB names/entries under memory
+  pressure.
+
+  The ADB memory cleaning is opportunistic even when we are under memory
+  pressure (in the overmem condition).  Split the opportunistic LRU
+  cleaning and overmem cleaning and make the overmem cleaning always
+  cleanup double of the newly allocated adbname/adbentry to ensure we
+  never allocate more memory than the assigned limit.
+
+- Prevent spurious validation failures.
+
+  Under rare circumstances, validation could fail if multiple clients
+  simultaneously iterated the same set of signatures.
+
+  References #3014
+
+- Rescan the interfaces again when reconfiguring the server.
+
+  On FreeBSD, the server would not listen on the configured 'localhost'
+  interfaces immediately, but only after the 'interface-interval' period
+  has passed.  After the fix for default interface-interval was merged
+  in !10281, this means the server would listen on the localhost after
+  60 minutes.
+
+  Rescan the interfaces immediately after configuring the
+  interface-interval value to start listening on the 'localhost'
+  interface immediately.
