+BIND 9.18.44
+------------
+
+Security Fixes
+~~~~~~~~~~~~~~
+
+- [CVE-2025-13878] Fix incorrect length checks for BRID and HHIT
+  records. ``d556bde123``
+
+  Malformed BRID and HHIT records could trigger an assertion failure.
+  This has been fixed.
+
+  ISC would like to thank Vlatko Kosturjak from Marlink Cyber for
+  bringing this vulnerability to our attention. :gl:`#5616`
+
+Feature Changes
+~~~~~~~~~~~~~~~
+
+- Support compilation with cmocka 2.0.0+ ``184df12da4``
+
+  The `assert_in_range()` function was deprecated in favor of
+  `assert_int_in_range()` and `assert_uint_in_range()`. Add
+  compatibility shims for cmocka<2.0.0 and use the new functions.
+  :gl:`#5699` :gl:`!11438`
+
+Bug Fixes
+~~~~~~~~~
+
+- Allow glue in delegations with QTYPE=ANY. ``21ad0222b7``
+
+  When a query for type ANY triggered a delegation response, all
+  additional data was omitted from the response, including mandatory
+  glue. This has been corrected. :gl:`#5659` :gl:`!11368`
+
+- Reconfigure NSEC3 opt-out zone to NSEC causes zone to be invalid.
+  ``53cfe984e3``
+
+  A zone that is signed with NSEC3, opt-out enabled, and then
+  reconfigured to use NSEC, causes the zone to be published with missing
+  NSEC records. This has been fixed. :gl:`#5679` :gl:`!11402`
