+Notes for BIND 9.17.4
+---------------------
+
+Security Fixes
+~~~~~~~~~~~~~~
+
+- None.
+
+Known Issues
+~~~~~~~~~~~~
+
+- None.
+
+New Features
+~~~~~~~~~~~~
+
+- ``rndc`` has been updated to use the new BIND network manager API.
+  This change had the side effect of altering the TCP timeout for RNDC
+  connections from 60 seconds to the ``tcp-idle-timeout`` value, which
+  defaults to 30 seconds. Also, because the network manager currently
+  has no support for UNIX-domain sockets, those cannot now be used
+  with ``rndc``. This will be addressed in a future release, either by
+  restoring UNIX-domain socket support or by formally declaring them
+  to be obsolete in the control channel. [GL #1759]
+
+Feature Changes
+~~~~~~~~~~~~~~~
+
+- None.
+
+Bug Fixes
+~~~~~~~~~
+
+- Addressed an error in recursive clients stats reporting.
+  There were occasions when an incoming query could trigger a prefetch for
+  some eligible rrset, and if the prefetch code were executed before recursion,
+  no increment in recursive clients stats would take place. Conversely,
+  when processing the answers, if the recursion code were executed before the
+  prefetch, the same counter would be decremented without a matching increment.
+  [GL #1719]
+
+- The introduction of KASP support broke whether the second field
+  of sig-validity-interval was treated as days or hours. (Thanks to
+  Tony Finch.) [GL !3735]
