--- other: - | A new ``nova-manage`` command, ``placement audit``, has been added. This can be used to identify and optionally remove compute allocations in placement that are no longer referenced by existing instances or migrations. These orphaned allocations typically occur due to race conditions during instance migration or removal and will result in capacity issues if not addressed. For more details on CLI usage, see the man page entry: https://docs.openstack.org/nova/latest/cli/nova-manage.html#placement
