 ### Added
 - Add support for Warm Indices Write Block on Flood Watermark breach ([#18375](https://github.com/opensearch-project/OpenSearch/pull/18375))
 - Add support for custom index name resolver from cluster plugin ([#18593](https://github.com/opensearch-project/OpenSearch/pull/18593))
+- Disallow resize for Warm Index, add Parameterized ITs for close in remote store ([#18686](https://github.com/opensearch-project/OpenSearch/pull/18686))
 - Ability to run Code Coverage with Gradle and produce the jacoco reports locally ([#18509](https://github.com/opensearch-project/OpenSearch/issues/18509))
 - Add NodeResourceUsageStats to ClusterInfo ([#18480](https://github.com/opensearch-project/OpenSearch/issues/18472))
 - Introduce SecureHttpTransportParameters experimental API (to complement SecureTransportParameters counterpart) ([#18572](https://github.com/opensearch-project/OpenSearch/issues/18572))
