22.1.0
^^^^^^


Known Issues
************

* When the tempest test coverage was added for resize and cold
  migrate with neutron ports having QoS minimum bandwidth policy rules
  we discovered that the cross cell resize code path cannot handle
  such ports. See bug https://bugs.launchpad.net/nova/+bug/1907522 for
  details. A fix was implemented that makes sure that Nova falls back
  to same-cell resize if the server has such ports.


Upgrade Notes
*************

* Nova services only support old computes if the compute is not
  older than the previous major nova release. From now on nova
  services will emit a warning at startup if the deployment contains
  too old compute services. From the 23.0.0 (Wallaby) release nova
  services will refuse to start if the deployment contains too old
  compute services to prevent compatibility issues.
