+BIND 9.20.18
+------------
+
+Security Fixes
+~~~~~~~~~~~~~~
+
+- [CVE-2025-13878] Fix incorrect length checks for BRID and HHIT
+  records. ``d4c0d61701``
+
+  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+ ``bb9234c6ce``
+
+  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:`!11437`
+
+- Add more information to the rndc recursing output about fetches.
+  ``9766feb4df``
+
+  This adds more information about the active fetches for debugging and
+  diagnostic purposes. :gl:`!11358`
+
+Bug Fixes
+~~~~~~~~~
+
+- Make key rollovers more robust. ``7a70d05b5d``
+
+  A manual rollover when the zone is in an invalid DNSSEC state causes
+  predecessor keys to be removed too quickly. Additional safeguards to
+  prevent this have been added. DNSSEC records will not be removed from
+  the zone until the underlying state machine has moved back into a
+  valid DNSSEC state. :gl:`#5458` :gl:`!11329`
+
+- Fix a catalog zones issue when a member zone could fail to load.
+  ``95cbc2c327``
+
+  A catalog zone's member zone could fail to load in some rare cases,
+  when the internally generated zone configuration string was exceeding
+  512 bytes. That condition only was not enough for the issue to arise,
+  but it was a necessary condition. This could happen, for example, if
+  the catalog zone's default primary servers list contained a large
+  number of items. This has been fixed. :gl:`#5658` :gl:`!11349`
+
+- Allow glue in delegations with QTYPE=ANY. ``441158ac18``
+
+  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:`!11283`
+
+- Adding NSEC3 opt-out records could leave invalid records in chain.
+  ``1b90296e1f``
+
+  When creating an NSEC3 opt-out chain, a node in the chain could be
+  removed too soon, causing the previous NSEC3 being unable to be found,
+  resulting in invalid NSEC3 records to be left in the zone. This has
+  been fixed. :gl:`#5671` :gl:`!11340`
+
+- Fix slow speed of NSEC3 optout large delegation zone signing.
+  ``88f915b77b``
+
+  BIND 9.20 takes much more time signing a large delegation zone with
+  NSEC3 optout compared to version 9.18. This has been restored.
+  :gl:`#5672` :gl:`!11362`
+
+- Reconfigure NSEC3 opt-out zone to NSEC causes zone to be invalid.
+  ``1d0e19c612``
+
+  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:`!11401`
+
+- Fix a possible catalog zone issue during reconfiguration.
+  ``911b45b2b3``
+
+  The :iscman:`named` process could terminate unexpectedly during
+  reconfiguration when a catalog zone update was taking place at the
+  same time. This has been fixed. :gl:`!11386`
+
+- Fix the charts in the statistics channel. ``7c7b01dd65``
+
+  The charts in the statistics channel could sometimes fail to render in
+  the browser, and were completely disabled for Mozilla-based browsers
+  for historical reasons. This has been fixed. :gl:`!11364`
+
