+Notes for BIND 9.16.10
+----------------------
+
+New Features
+~~~~~~~~~~~~
+
+- NSEC3 support was added to KASP. A new option for ``dnssec-policy``,
+ ``nsec3param``, can be used to set the desired NSEC3 parameters.
+ NSEC3 salt collisions are automatically prevented during resalting.
+ :gl:`#1620`
+
+Feature Changes
+~~~~~~~~~~~~~~~
+
+- The default value of ``max-recursion-queries`` was increased from 75
+ to 100. Since the queries sent towards root and TLD servers are now
+ included in the count (as a result of the fix for CVE-2020-8616),
+ ``max-recursion-queries`` has a higher chance of being exceeded by
+ non-attack queries, which is the main reason for increasing its
+ default value. :gl:`#2305`
+
+- The default value of ``nocookie-udp-size`` was restored back to 4096
+ bytes. Since ``max-udp-size`` is the upper bound for
+ ``nocookie-udp-size``, this change relieves the operator from having
+ to change ``nocookie-udp-size`` together with ``max-udp-size`` in
+ order to increase the default EDNS buffer size limit.
+ ``nocookie-udp-size`` can still be set to a value lower than
+ ``max-udp-size``, if desired. :gl:`#2250`
+
+Bug Fixes
+~~~~~~~~~
+
+- Handling of missing DNS COOKIE responses over UDP was tightened by
+ falling back to TCP. :gl:`#2275`
+
+- The CNAME synthesized from a DNAME was incorrectly followed when the
+ QTYPE was CNAME or ANY. :gl:`#2280`
+
+- Building with native PKCS#11 support for AEP Keyper has been broken
+ since BIND 9.16.6. This has been fixed. :gl:`#2315`
+
+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.
