===== API changes

* `capabilities` - Adds `local_only` boolean parameter: True if only the node being called should be considered.
* `cluster.stats`- Removes `flat_settings` parameter, adds `include_remotes` boolean parameter: Include remote cluster data into the response (default: false).
* `indices.get_data_stream` - Adds `verbose` boolean parameter: Whether the maximum timestamp for each data stream should be calculated and returned (default: false). Adds `master_timeout` (see below).
* `query_rules.delete_ruleset` - Accepts `ignore: 404` common parameter.

These parameters have been added to several APIs:

* `master_timeout` timeout for processing on master node.
* `timeout` timeout for acknowledgement of update from all nodes in cluster parameters.

Added in:

* `indices.create_data_stream` - both.
* `indices.delete_data_stream` - `master_timeout`.
* `indices.get_data_lifecycle` - `master_timeout`.
* `indices.get_data_stream` - `master_timeout`.
* `indices.migrate_to_data_stream` - both.
* `indices.promote_data_stream` - `master_timeout`.
* `search_shards` - `master_timeout`.

**APIs Promoted from Experimental to Stable:**

* `indices.delete_data_lifecycle`
* `indices.explain_data_lifecycle`
* `indices.get_data_lifecycle`
* `indices.put_data_lifecycle`
* `security.create_cross_cluster_api_key`
* `security.update_cross_cluster_api_key`

**New APIs**

* `ingest.delete_ip_location_database` - Deletes an ip location database configuration.
* `ingest.get_ip_location_database` - Returns the specified ip location database configuration.
* `ingest.put_ip_location_database` - Puts the configuration for a ip location database to be downloaded.


**New Experimental APIs**

* `inference.stream_inference` - Perform streaming inference.
* `query_rules.test` - Tests a query ruleset to identify the rules that would match input criteria.
