anchor.diff:  In Elasticsearch 7.7.0, the setting `cluster.remote.connect` was deprecated in
   favor of setting `node.remote_cluster_client`. In Elasticsearch 8.0.0, the
   setting `cluster.remote.connect` is removed.
  +
  +*Impact* +
  +Use the `node.remote_cluster_client` setting. Discontinue use of the
  +`cluster.remote.connect` setting. Specifying the `cluster.remote.connect`
  +setting in `elasticsearch.yml` will result in an error on startup.
   ====
   
   .The `node.local_storage` setting has been removed.
  
positive.code: To ensure that all settings are in a proper namespace, the `pidfile` setting was
  previously deprecated in version 7.4.0 of Elasticsearch, and is removed in
  version 8.0.0. Instead, use `node.pidfile`.
  ====
  
  [[remove-processors]]
  
negative.code: an increase in the number of physical CPUs on which to schedule these additional
  threads, the `node.processors` setting is now bounded by the number of available
  processors.
  
  *Impact* +
  If specified, ensure the value of `node.processors` setting does not exceed the
  number of available processors. Setting the `node.processors` value greater than
  the number of available processors in `elasticsearch.yml` will result in an
  error on startup.
