+Notes for BIND 9.19.18
+----------------------
+
+New Features
+~~~~~~~~~~~~
+
+- The statistics channel now includes information about incoming zone
+  transfers that are currently in progress. :gl:`#3883`
+
+- The new :any:`resolver-use-dns64` option enables :iscman:`named` to
+  apply :any:`dns64` rules to IPv4 server addresses when sending
+  recursive queries, so that resolution can be performed over a NAT64
+  connection. :gl:`#608`
+
+Removed Features
+~~~~~~~~~~~~~~~~
+
+- Support for the ``lock-file`` statement and the ``named -X``
+  command-line option has been removed. An external process supervisor
+  should be used instead. :gl:`#4391`
+
+  Alternatively, the ``flock`` utility (part of util-linux) can be used
+  on Linux systems to achieve the same effect as ``lock-file`` or
+  ``named -X``:
+
+  ::
+
+    flock -n -x <directory>/named.lock <path>/named <arguments>
+
+- Configuring the control channel to use a Unix domain socket has been a
+  fatal error since BIND 9.18. The feature has now been completely
+  removed and :iscman:`named-checkconf` now reports it as a
+  configuration error. :gl:`#4311`
+
+Feature Changes
+~~~~~~~~~~~~~~~
+
+- Processing large incremental transfers (IXFR) has been offloaded to a
+  separate work thread so that it does not prevent networking threads
+  from processing regular traffic in the meantime. :gl:`#4367`
+
+- QNAME minimization is now used when looking up the addresses of name
+  servers during the recursive resolution process. :gl:`#4209`
+
+- The :any:`inline-signing` zone option is now ignored if there is no
+  :any:`dnssec-policy` configured for the zone. This means that unsigned
+  zones no longer create redundant signed versions of the zone.
+  :gl:`#4349`
+
+- The IP addresses for B.ROOT-SERVERS.NET have been updated to
+  170.247.170.2 and 2801:1b8:10::b. :gl:`#4101`
+
+Bug Fixes
+~~~~~~~~~
+
+- :any:`max-cache-size` accidentally became ineffective in BIND 9.19.16.
+  This has been fixed and the option now behaves as documented again.
+  :gl:`#4340`
+
+- If the unsigned version of an inline-signed zone contained DNSSEC
+  records, it was incorrectly scheduled for resigning. This has been
+  fixed. :gl:`#4350`
+
+- Looking up stale data from the cache did not take local authoritative
+  data into account. This has been fixed. :gl:`#4355`
+
+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.
