21.2.0
^^^^^^


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.


Bug Fixes
*********

* In the Rocky (18.0.0) release support was added to nova to use
  neutron's multiple port binding feature when the binding-extended
  API extension is available. In the Train (20.0.0) release the SR-IOV
  live migration feature broke the semantics of the vifs field in the
  "migration_data" object that signals if the new multiple port
  binding workflow should be used by always populating it even when
  the "binding-extended" API extension is not present. This broke live
  migration for any deployment that did not support the optional
  "binding-extended" API extension. The Rocky behavior has now been
  restored enabling live migration using the single port binding
  workflow when multiple port bindings are not available.
