21.2.1 ^^^^^^
New Features ************
* Remote address group support was added to the iptables-based firewall drivers (IptablesFirewallDriver and OVSHybridIptablesFirewallDriver), Previously it was only available in the OVSFirewallDriver. For more information, see bug 2058138 (https://bugs.launchpad.net/neutron/+bug/2058138).
Known Issues ************
* The fix of bug 2048785 (https://bugs.launchpad.net/neutron/+bug/2048785) only fixes newly created trunk parent ports. If the fix of already existing trunks is needed, then either delete and re-create the affected trunks or set tpt ports' vlan_mode and tag manually: "ovs-vsctl set Port tpt-... vlan_mode=access tag=0"
Bug Fixes *********
* The config option "agent_down_time" is now limited to a maximum value of *2147483*, as neutron-server will fail to start if it is configured higher. See bug 2028724 (https://bugs.launchpad.net/neutron/+bug/2028724) for more information.
* [bug 2036423 (https://bugs.launchpad.net/neutron/+bug/2036423)] Now it is not possible to delete a subnet gateway IP if that subnet has a router interface; the subnet gateway IP modification was already forbidden.
* When synchronizing the OVN databases, either when running the migration command or during startup, the code responsible for synchronization will only clean up segment-to-host mappings for hosts with agent_type "OVN Controller agent". Before, the synchronization would clean up (delete) segment-to-host mappings for non-OVN hosts. Fixes bug: 2040172 (https://bugs.launchpad.net/neutron/+bug/2040172).
Other Notes ***********
* Added extension "subnetpool-prefix-ops" to the ML2/OVN mechanism driver.
