component	Updater	Detecting when Home Assistant updates are available.	2015-11-15 20:40	true	false	true	true	Other

The updater component will detect when the newest published version of Home Assistant does not match the currently installed version. When running, it will check for new releases at startup and everyday at noon and midnight.

For an added bonus, an automation component can be created to send a message with a notifier when that state of this component's entity changes.

automation:
  alias: 'Update Available Notifications'
  trigger:
    platform: state
    entity_id: updater.updater
  action:
    service: notify.notify
    data:
      message: 'Home Assistant update is available.'
