+Notes for BIND 9.20.16
+----------------------
+
+Bug Fixes
+~~~~~~~~~
+
+- Fix dnssec-keygen key collision checking for KEY rrtype keys.
+
+  The :iscman:`dnssec-keygen` utility program failed to detect possible
+  Key ID collisions with the existing keys generated using the
+  non-default ``-T KEY`` option (e.g. for ``SIG(0)``). This has been
+  fixed. :gl:`#5506`
+
+- Fix shutdown INSIST in dns_dispatchmgr_getblackhole.
+
+  Previously, `named` could trigger an assertion in
+  `dns_dispatchmgr_getblackhole` while shutting down. This has been
+  fixed. :gl:`#5525`
+
+- Dnssec-verify now uses exit code 1 when failing due to illegal
+  options.
+
+  Previously, dnssec-verify exited with code 0 if the options could not
+  be parsed. This has been fixed. :gl:`#5574`
+
+- Prevent assertion failures of dig when server is specified before the
+  -b option.
+
+  Previously, :iscman:`dig` could exit with an assertion failure when
+  the server was specified before the :option:`dig -b` option. This has
+  been fixed. :gl:`#5609`
+
+- Skip unsupported algorithms when looking for signing key.
+
+  A mix of supported and unsupported DNSSEC algorithms in the same zone
+  could have caused validation failures. Ignore the DNSSEC keys with
+  unsupported algorithm when looking for the signing keys. :gl:`#5622`
+
+- Skip buffer allocations if not logging.
+
+  Currently, during IXFR we allocate a 2KB buffer for IXFR change
+  logging regardless of the log level. This commit introduces an early
+  check on the log level in dns_diff_print to avoid this.
+
+  Results in a speedup from 28% in the test case from issue #5442.
