+Notes for BIND 9.16.9
+---------------------
+
+New Features
+~~~~~~~~~~~~
+
+- A new configuration option, ``stale-refresh-time``, has been
+ introduced. It allows a stale RRset to be served directly from cache
+ for a period of time after a failed lookup, before a new attempt to
+ refresh it is made. :gl:`#2066`
+
+Bug Fixes
+~~~~~~~~~
+
+- ``named`` could crash with an assertion failure if a TCP connection
+ were closed while a request was still being processed. :gl:`#2227`
+
+- ``named`` acting as a resolver could incorrectly treat signed zones
+ with no DS record at the parent as bogus. Such zones should be treated
+ as insecure. This has been fixed. :gl:`#2236`
+
+- After a Negative Trust Anchor (NTA) is added, BIND performs periodic
+ checks to see if it is still necessary. If BIND encountered a failure
+ while creating a query to perform such a check, it attempted to
+ dereference a ``NULL`` pointer, resulting in a crash. :gl:`#2244`
+
+- A problem obtaining glue records could prevent a stub zone from
+ functioning properly, if the authoritative server for the zone were
+ configured for minimal responses. :gl:`#1736`
+
+- ``UV_EOF`` is no longer treated as a ``TCP4RecvErr`` or a
+ ``TCP6RecvErr``. :gl:`#2208`
+
+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.
