based clouds.

This release is part of the pike stable release series.

For more details, please see below.

1.4.0
^^^^^

New Features

* Add notifications related to Action object.

* Added the functionality to filter out instances which have
  metadata field 'optimize' set to False. For now, this is only
  available for the basic_consolidation strategy (if
  "check_optimize_metadata" configuration option is enabled).

* Added binding between apscheduler job and Watcher decision engine
  service. It will allow to provide HA support in the future.

* Enhancement of vm_workload_consolidation strategy by using
  'memory.resident' metric in place of 'memory.usage', as memory.usage
  shows the memory usage inside guest-os and memory.resident
  represents volume of RAM used by instance on host machine.

* There is new ability to create Watcher continuous audits with cron
  interval. It means you may use, for example, optional argument '--
  interval "*/5 * * * *"' to launch audit every 5 minutes. These jobs
  are executed on a best effort basis and therefore, we recommend you
  to use a minimal cron interval of at least one minute.

* Add description property for dynamic action. Admin can see detail
  information of any specify action.

* Added gnocchi support as data source for metrics. Administrator
  can change data source for each strategy using config file.

* Added using of JSONSchema instead of voluptuous to validate
  Actions.

* Added strategy to identify and migrate a Noisy Neighbor - a low
  priority VM that negatively affects peformance of a high priority VM
  by over utilizing Last Level Cache.

* Add notifications related to Service object.

* Added volume migrate action
