21.1.0 ^^^^^^
New Features ************
* Address scope is now added to all OVN LSP port registers in the northbound. Northd then writes the address scope from the northbound to the southbound so it can be used there by the ovn-bgp-agent.
Known Issues ************
* Until the OVN bug (https://bugzilla.redhat.com/show_bug.cgi?id=2162756) is fixed, setting the "reside-on-redirect-chassis" to true for the logical router port associated to vlan provider network is needed. This workaround makes the traffic centrallized, but not tunneled, through the node with the gateway port, thus avoiding MTU issues.
Upgrade Notes *************
* The default value for the "metadata_workers" configuration option has changed to 0 for the ML2/OVN driver. Since [OVN] Allow to execute "MetadataProxyHandler" in a local thread (https://review.opendev.org/c/openstack/neutron/+/861649), the OVN metadata proxy handler can be spawned in the same process of the OVN metadata agent, in a local thread. That reduces the number of OVN SB database connections to one.
Bug Fixes *********
* [bug 2003455 (https://bugs.launchpad.net/neutron/+bug/2003455)] It is added an extra checking to ensure the "reside-on-redirect- chassis" is set to true for the logical router port associated to vlan provider network despite having the "ovn_distributed_floating_ip" enabled or not. This is needed as there is an OVN bug (https://bugzilla.redhat.com/show_bug.cgi?id=2162756) making it not work as expected. Until that is fixed, we need these workaround that makes the traffic centrallized, but not tunneled, through the node with the gateway port, thus avoiding MTU issues.
* Normalise OVN agent heartbeat timestamp format to match other agent types. This fixes parsing of "GET /v2.0/agents" for some clients, such as gophercloud.
* Neutron can record full connection using log-related feature introduced in OVN 21.12. For more info see *bug LP#https://bugs.launchpad.net/neutron/+bug/2003706*
Other Notes ***********
* Since OVN 20.06, the "Chassis" register configuration is stored in the "other_config" field and replicated into "external_ids". This replication is stopped in OVN 22.09. The ML2/OVN plugin tries to retrieve the "Chassis" configuration from the "other_config" field first; if this field does not exist (in OVN versions before 20.06), the plugin will use "external_ids" field instead. Neutron will be compatible with the different OVN versions (with and without "other_config" field).
