+        * systemd-nspawn gained a new --network-zone= switch, that allows
+          creating ad-hoc virtual Ethernet links between multiple containers,
+          that only exist as long as at least one container referencing them is
+          running. This allows easy connecting of multiple containers with a
+          common link that implements an Ethernet broadcast domain. Each of
+          these network "zones" may be named relatively freely by the user, and
+          may be referenced by any number of containers, but each container may
+          only reference one of these "zones". On the lower level, this is
+          implemented by an automatically managed bridge network interface for
+          each zone, that is created when the first container referencing its
