+=== Logstash 8.16.0 Release Notes
+
+==== Announcing the new {ls} Health Report API
+
+The new Health Report API (`GET /_health_report`) is available starting with {ls} `8.16.0`.
+This API leverages indicators capable of detecting the degraded status of pipelines and
+providing actionable insights https://github.com/elastic/logstash/pull/16520[#16520], https://github.com/elastic/logstash/pull/16532[#16532].
+
+NOTE for users upgrading to {ls} 8.16.0: if your existing automation relies on liveliness scripts that expect Logstash's API status to either not be available or return a hardcoded `green` status, there is an escape hatch to prevent the new Health API's status from affecting the top-level `status` field of Logstash's existing API responses. Setting the `logstash.forceApiStatus` system property to `green` will force other APIs to return the previous hard-coded `green` value. https://github.com/elastic/logstash/pull/16535[#16535]
+
+For a more detailed view please check <<logstash-health-report-api>>.
+
+[[featured-8.16.0]]
+==== New features and enhancements
+
+* {ls} now gracefully handles `if` conditionals in pipeline definitions that can't be evaluated (https://github.com/elastic/logstash/pull/16322[#16322]), either by dropping
+the event or by sending it to the pipeline's DLQ if enabled. https://github.com/elastic/logstash/pull/16423[#16423]
+
+[[core-8.16.0]]
+==== Other changes to Logstash core
+
+* Added deprecation logs for modules `netflow`, `fb_apache` and `azure`. https://github.com/elastic/logstash/pull/16548[#16548]
+
+* Added deprecation logs for users that doesn't explicitly select a value for `pipeline.buffer.type` forcing them to proactively make a choice before version `9.0` when this setting will default to heap. https://github.com/elastic/logstash/pull/16498[#16498]
+
+* The flag `--event_api.tags.illegal` was deprecated and will be removed in version 9. This flag remains available throughout all version 8.x releases. Users who rely on this flag to allow non strings assignment to `tags` field should update their pipeline. https://github.com/elastic/logstash/pull/16507[#16507]
