-[discrete]
-==== Breaking changes
-
-[discrete]
-===== Drop support for deprecated `body` parameter
-
-In 8.0, the top-level `body` parameter that was available on all API functions <<remove-body-key,was deprecated>>. In 9.0 this property is completely removed.
-

-=== 8.16.2

-
-[discrete]
-===== Improved support for Elasticsearch `v8.16`
-
-Updated TypeScript types based on fixes and improvements to the Elasticsearch specification.
-
-[discrete]
-===== Drop testing artifacts from npm package
-
-Tap, the unit testing tool used by this project, was recently upgraded and started writing to a `.tap` directory. Since tests are run prior to an `npm publish` in CI, this directory was being included in the published package and bloating its size.

-
-[discrete]
-===== Support Apache Arrow in ES|QL helper
-
-The ES|QL helper can now return results as an Apache Arrow `Table` or `RecordBatchReader`, which enables high-performance calculations on ES|QL results, even if the response data is larger than the system's available memory. See <<esql-helper>> for more information.
-
-[discrete]
-==== Fixes
-
-[discrete]
-===== Pass prototype poisoning options to serializer correctly
-
-The client's `disablePrototypePoisoningProtection` option was set to `true` by default, but when it was set to any other value it was ignored, making it impossible to enable prototype poisoning protection without providing a custom serializer implementation.

The `required_capacity` is calculated as the maximum of the `required_capacity` result of all individual deciders that are enabled for the policy. The operator should verify that the `current_nodes` match the operator’s knowledge of the cluster to avoid making autoscaling decisions based on stale or incomplete information. The response contains decider-specific information you can use to diagnose how and why autoscaling determined a certain capacity was required. This information is provided for diagnosis only.
