+- The new networking code introduced in BIND 9.16 (netmgr) was
+  overhauled in order to make it more stable, testable, and
+  maintainable. [GL #2321]
+
+- Earlier releases of BIND versions 9.16 and newer required the
+  operating system to support load-balanced sockets in order for
+  ``named`` to be able to achieve high performance (by distributing
+  incoming queries among multiple threads). However, the only operating
+  systems currently known to support load-balanced sockets are Linux and
+  FreeBSD 12, which means both UDP and TCP performance were limited to a
+  single thread on other systems. As of BIND 9.17.8, ``named`` attempts
+  to distribute incoming queries among multiple threads on systems which
+  lack support for load-balanced sockets (except Windows). [GL #2137]
