1.8.0
^^^^^

New Features

* A new vitrage-collector service was added, in order to separate
  the datasource loading from the Vitrage graph processing. This
  change allows better HA support and will enable storing the
  datasources events in a database in order to support alarm history.

* Vitrage now supports authentication with KeyCloak server using
  OpenId Connect protocol.

* A new service was added to Vitrage, the machine learning service.
  Together with it, the first machine learning plugin was added - the
  Jaccard Correlation plugin. This plugin listens to rabbit MQ
  receiving messages about creation and deletion of alarms, and learns
  the correlation between each pair of alarms, in order to recommend
  on creation of new templates in the future.

* Integration with Mistral (the OpenStack workflow service). The
  Vitrage user can specify in a Vitrage template that if a certain
  condition is met (like an alarm on the host, or a combination of a
  few alarms) a Mistral workflow should be executed. The workflow can
  be used, for example, to take corrective actions.
