+Notes for BIND 9.18.12
+----------------------
+
+Removed Features
+~~~~~~~~~~~~~~~~
+
+- Specifying a ``port`` when configuring source addresses (i.e., as an
+  argument to :any:`query-source`, :any:`query-source-v6`,
+  :any:`transfer-source`, :any:`transfer-source-v6`,
+  :any:`notify-source`, :any:`notify-source-v6`, :any:`parental-source`,
+  or :any:`parental-source-v6`, or in the ``source`` or ``source-v6``
+  arguments to :any:`primaries`, :any:`parental-agents`,
+  :any:`also-notify`, or :any:`catalog-zones`) has been deprecated. In
+  addition, the :any:`use-v4-udp-ports`, :any:`use-v6-udp-ports`,
+  :any:`avoid-v4-udp-ports`, and :any:`avoid-v6-udp-ports` options have
+  also been deprecated.
+
+  Warnings are now logged when any of these options are encountered in
+  ``named.conf``. In a future release, they will be made nonfunctional.
+  :gl:`#3781`
+
+Bug Fixes
+~~~~~~~~~
+
+- A constant stream of zone additions and deletions via ``rndc
+  reconfig`` could cause increased memory consumption due to delayed
+  cleaning of view memory. This has been fixed. :gl:`#3801`
+
+- The speed of the message digest algorithms (MD5, SHA-1, SHA-2), and of
+  NSEC3 hashing, has been improved. :gl:`#3795`
+
+- Pointing :any:`parental-agents` to a resolver did not work because the
+  RD bit was not set on DS requests. This has been fixed. :gl:`#3783`
+
+- Building BIND 9 failed when the ``--enable-dnsrps`` switch for
+  ``./configure`` was used. This has been fixed. :gl:`#3827`
+
+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.
