16.3.2
^^^^^^

Other Notes

* To improve performance of the DHCP agent, it will no longer
  configure the DHCP server for every port type created in Neutron.
  For example, for floating IP or router HA interfaces there is no
  need since a client will not make a DHCP request for them

* The "OVN Metadata Agent" now creates the network namespaces
  including the Neutron network UUID in its name. Previously, the OVN
  datapath UUID was used and it was not obvious for operators and
  during debugging to figure out which namespace corresponded to what
  Neutron network.
