 * Value type is <<string,string>>
 * Supported values are:
 ** `disabled`: does not use ECS-compatible field names (using `host` field to store host name)
-** `v1`: uses fields that are compatible with Elastic Common Schema (using `[host][hostname]`)
+** `v1`,`v8`: uses fields that are compatible with Elastic Common Schema (using `[host][hostname]`)
 * Default value depends on which version of Logstash is running:
 ** When Logstash provides a `pipeline.ecs_compatibility` setting, its value is used as the default
 ** Otherwise, the default value is `disabled`.
