* systemd-networkd gained support for vti6 tunnels.
+ * Note that systemd-networkd manages the sysctl variable
+ /proc/sys/net/ipv[46]/conf/*/forwarding for each interface
+ it is configured for since v219. The variable controls IP
+ forwarding, and is a per-interface alternative to the global
+ /proc/sys/net/ipv[46]/ip_forward. This setting is
+ configurable in the IPForward= option, which defaults to
+ "no". This means if networkd is used for an interface it is
+ no longer sufficient to set the global sysctl option to turn
+ on IP forwarding! Instead, the .network file option
+ IPForward= needs to be turned on! Note that the
+ implementation of this behaviour was broken in v219 and has
+ been fixed in v220.

* Many bonding and vxlan options are now configurable in
systemd-networkd.
