- Create separate transport action for render search template action ([#11170](https://github.com/opensearch-project/OpenSearch/pull/11170))
- Add additional handling in SearchTemplateRequest when simulate is set to true ([#11591](https://github.com/opensearch-project/OpenSearch/pull/11591))
- Introduce cluster level setting `cluster.index.restrict.replication.type` to prevent replication type setting override during index creations([#11583](https://github.com/opensearch-project/OpenSearch/pull/11583))
- Add match_only_text field that is optimized for storage by trading off positional queries performance ([#6836](https://github.com/opensearch-project/OpenSearch/pull/11039))

### Dependencies
- Bumps jetty version to 9.4.52.v20230823 to fix GMS-2023-1857 ([#9822](https://github.com/opensearch-project/OpenSearch/pull/9822))
