  * Get cluster info. Get basic build, version, and cluster information. ::: In Serverless, `version.number` always reports the next target Elasticsearch release version at the time of the request. Serverless does not track to a traditional release versioning model; it is continuously updated. The version number is provided to maintain compatibility with existing clients, but it is not meaningful for assessing feature availability. Clients should detect a Serverless environment by checking for `build_flavor: serverless`.
