@@ -110,6 +110,7 @@ The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/),
 - The `phone-search` analyzer no longer emits the tel/sip prefix, international calling code, extension numbers and unformatted input as a token ([#16993](https://github.com/opensearch-project/OpenSearch/pull/16993))
 - Stop processing search requests when _msearch request is cancelled ([#17005](https://github.com/opensearch-project/OpenSearch/pull/17005))
 - Fix GRPC AUX_TRANSPORT_PORT and SETTING_GRPC_PORT settings and remove lingering HTTP terminology ([#17037](https://github.com/opensearch-project/OpenSearch/pull/17037))
+- Use OpenSearch version to deserialize remote custom metadata([#16494](https://github.com/opensearch-project/OpenSearch/pull/16494))
