+
+#### API changes
+
+* `cluster.get_component_template` - Adds `flat_settings` boolean parameter, return settings in flat format (default: false). Adds `settings_filter` String parameter, filter out results, for example to filter out sensitive information.
+* `cluster.put_component_template` - Removes `timeout` parameter, adds `cause` String parameter, used defined reason for creation.
+* `create` - Adds `require_alias` and `require_data_stream` boolean parameters, to specify required type to be created.
+* `eql.search` - Adds `ccs_minimize_roundtrips`, `ignore_unavailable`, `allow_no_indices` boolean parameters and `expand_wildcards` String parameter.
+* `esql.async_query` - Adds `allow_partial_results` boolean parameter.
+* `esql.async_query_get` - Adds `format` String parameter (e.g. json, yaml).
+* `esql.query` -  Adds `allow_partial_results` boolean parameter.
+* `indices.recovery` - Adds `ignore_unavailable`, `allow_no_indices` boolean parameters and `expand_wildcards` String parameter.
+* `msearch` - Adds `ignore_unavailable`, `ignore_throttled`, `allow_no_indices`, `include_named_queries_score` boolean parameters, `expand_wildcards` String parameter and `routing`, a comma-separated list of specific routing values.
+* `open_point_in_time` - Adds `max_concurrent_shard_requests` parameter, the number of concurrent shard requests per node executed concurrently when opening this point-in-time
+* `reindex` - Adds `require_alias` boolean parameter.
+* `search_mvt` - Adds `grid_agg` String parameter, aggregation used to create a grid for `field`.
+* `snapshot.repository_analyze` - Adds `register_operation_count` parameter, the minimum number of linearizable register operations to perform in total.
+
+Time parameters `master_timeout` and `timeout` have been added to the following APIs:
+
+* `index_lifecycle_management`:
+** `delete_lifecycle`
+** `get_lifecycle`
+** `put_lifecycle`
+** `start`
+** `stop`
+** `explain_lifecycle` - Only `master_timeout`
+
+* `ingest`:
+** `delete_geoip_database`
+** `delete_ip_location_database`
+** `put_geoip_database`
+** `put_ip_location_database`
+
+#### New APIs
+
+* `indices.delete_data_stream_options` - Deletes the data stream options of the selected data streams.
+* `indices.get_data_stream_options` - Returns the data stream options of the selected data streams.
+* `indices.get_data_stream_settings` - Gets a data stream's settings.
+* `indices.put_data_stream_options` - Updates the data stream options of the selected data streams.
+* `indices.put_data_stream_settings` - Updates a data stream's settings.
+* `inference.put_amazonsagemaker` - Configure an Amazon SageMaker inference endpoint.
+* `inference.put_custom` - Configure a custom inference endpoint.
+* `inference.put_deepseek` - Configure a DeepSeek inference endpoint.
+
+
+## 8.18.0 Release notes
+
+### API
+
+#### New APIs:
+
+* `esql.async_query_stop` - Stops a previously submitted async query request given its ID and collects the results.
+* `inference.chat_completion_unified` - Perform chat completion inference
+* `inference.completion` - Perform completion inference
+* `inference.put_alibabacloud` - Configure an AlibabaCloud AI Search inference endpoint
+* `inference.put_amazonbedrock` - Configure an Amazon Bedrock inference endpoint
+* `inference.put_anthropic` - Configure an Anthropic inference endpoint
+* `inference.put_azureaistudio` - Configure an Azure AI Studio inference endpoint
+* `inference.put_azureopenai` - Configure an Azure OpenAI inference endpoint
+* `inference.put_cohere` - Configure a Cohere inference endpoint
+* `inference.put_elasticsearch` - Configure an Elasticsearch inference endpoint
+* `inference.put_elser` - Configure an ELSER inference endpoint
+* `inference.put_googleaistudio` - Configure a Google AI Studio inference endpoint
+* `inference.put_googlevertexai` - Configure a Google Vertex AI inference endpoint
+* `inference.put_hugging_face` - Configure a HuggingFace inference endpoint

+* `inference.sparse_embedding` - Perform sparse embedding inference
+* `inference.stream_inference` renamed to `inference.stream_completion` - Perform streaming completion inference.
+* `inference.text_embedding` - Perform text embedding inference
+
+#### Updated APIs:
+
+* `bulk`, `create`, `index`, `update` - Add Boolean parameter `:include_source_on_error`, if to include the document source in the error message in case of parsing errors (defaults to true).
+* `cat.segments`
+  * Adds  Boolean parameter `:local`, return local information, do not retrieve the state from master node (default: false).
+  * Adds Time parameter `:master_timeout`, explicit operation timeout for connection to master node.
+* `cat.tasks`
+  * Adds Time parameter `:timeout`, period to wait for a response. If no response is received before the timeout expires, the request fails and returns an error.
+  * Adds Boolean parameter `:wait_for_completion`, if `true`, the request blocks until the task has completed.
+* `eql.search`
+  * Adds Boolean parameter `:allow_partial_search_results`, control whether the query should keep running in case of shard failures, and return partial results.
+  * Adds Boolean parameter `:allow_partial_sequence_results`, control whether a sequence query should return partial results or no results at all in case of shard failures. This option has effect only if [allow_partial_search_results] is true.
+* `index_lifecycle_management.delete_lifecycle`, `index_lifecycle_management.explain_lifecycle`, `index_lifecycle_management.get_lifecycle`, `index_lifecycle_management.put_lifecycle`, `index_lifecycle_management.start`, `index_lifecycle_management.stop`, remove `:master_timeout`, `:timeout` parameters.
