19.6.0
^^^^^^


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.


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
***********

* The OVN migration performs validation by default. This validation
  means an instance is spawned and is tested by simple ping after the
  migration is finished. Also it tries to create new workload post
  migration. This is useful for very simple scenarios when migration
  is tested but is not really useful in production since likely the
  production envrionments already have running workloads. It makes
  more sense to require the validation explicitly rather than
  implicitly run it as the migration is mostly intended for
  production. The VALIDATE_MIGRATION now defaults to False and needs
  to be changed to True if validation upon request.
