  * Added the ability to set the `index` and `doc_type` dynamically in an index

  refresh policy of the write request. For more information, see

  //Pull: 3350

  buttons that can be clicked in slack messages. For more information, see

  //Pull: 3355
  * {watcher} indices (`.watch*` and `triggered_watches`) created after upgrading
  to 6.2 have the `auto_expand_replicas: 0-1` setting rather than a fixed setting
  of 1 replica. As a result, {watcher} indices created after upgrading to 6.2 can
  have a green status on single node clusters. There is no impact in multi-node
  clusters.
