20.2.0
^^^^^^


New Features
************

* OVN mechanism driver refuses to bind a port to a dead agent.


Other Notes
***********

* OVN driver reverted to using stateful NAT for floating IP
  implementation. The previous switch to stateless didn't materialize
  the expected performance benefits and instead introduced problems
  with potential hardware offloading.
