We joyfully announce the release of: neutron 20.2.0: OpenStack Networking This release is part of the yoga stable release series. The source is available from: https://opendev.org/openstack/neutron Download the package from: https://tarballs.openstack.org/neutron/ Please report issues through: https://bugs.launchpad.net/neutron/+bugs For more details, please see below. 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.
