  +=== API changes
  +
  +==== Suggest stats metrics deprecated
  +
  +The suggest stats were previously folded into the search on the indices stats
  +API. As such, the `suggest` metric on the indices stats API has been a synonym
  +for the `search` metric. In 6.3.0, the `suggest` metric is deprecated in favor
  +of using `search`.
  +
  +Similarly, the `suggest` index metric on the `indices` metric on the nodes stats
  +API has provided a response containing only an empty object since 5.0.0. In
  +6.3.0 this metric has been deprecated.

   === Plugins changes

   ==== Ingest Geoip Plugin
   
  -* In earlier versions, database files have been stored as gzip compressed files with the extension `.gz` to
  -save disk space. As a consequence, database files had to be loaded in memory. Now the default database files
  -that are stored uncompressed as `.mmdb` files which allows to memory-map them and save heap memory. Any
  -custom database files must also be stored uncompressed. Consequently, the `database_file` property in any
  -ingest pipelines that use the Geoip Processor must refer to the uncompressed database files as well.

   ==== Using the plugin installer without a TTY
   
  
positive.code: accept these permissions either by keeping standard input open and attaching a
  TTY (i.e., using interactive mode to accept the permissions), or by passing the
  `--batch` flag.
  
  ==== Concurrency level of analyze requests
  
  
negative.code: `-Des.thread_pool.write.use_bulk_as_display_name=true` to have Elasticsearch
  continue to display the name of this thread pool as `bulk`. Elasticsearch will
  stop observing this system property in 7.0.0.
