+Notes for BIND 9.19.23
+----------------------
+
+New Features
+~~~~~~~~~~~~
+
+- Added RESOLVER.ARPA to the built in empty zones. :gl:`#4580`
+
+Feature Changes
+~~~~~~~~~~~~~~~
+
+- Memory consumption of the new QP-trie database has been optimized. Large
+  zones, which used to require significantly more memory with QP-trie, now only
+  require roughly 15% more memory than the old red-black tree data structure.
+  :gl:`#4614`
+
+- The :any:`sortlist` option has been deprecated and will be removed in a
+  future BIND 9.21.x release. Users should not rely on a specific order of
+  resource records in DNS messages.  :gl:`#4593`
+
+- The ``fixed`` value for the :any:`rrset-order` option and the corresponding
+  ``configure`` script option have been deprecated and will be removed in a
+  future BIND 9.21.x release. Users should not rely on a specific order of
+  resource records in DNS messages.  :gl:`#4446`
+
+
+Bug Fixes
+~~~~~~~~~
+
+- A bug in the keymgr code unintentionally slowed down some DNSSEC key
+  rollovers. This has been fixed. :gl:`#4552`
+
+- Two bugs that could have caused resolvers configured with the new cache data
+  structure to crash or hang have been fixed. :gl:`#4622` :gl:`#4652`
+
+- Some ISO 8601 durations were accepted erroneously, leading to shorter
+  durations than expected. This has been fixed. :gl:`#4624`
+
+Known Issues
+~~~~~~~~~~~~
+
+- There are no new known issues with this release. See :ref:`above
+  <relnotes_known_issues>` for a list of all known issues affecting this
+  BIND 9 branch.
