 - Added response schema for `GET /_plugins/_knn/warmup/{index}` ([#717](https://github.com/opensearch-project/opensearch-api-specification/pull/717))
 - Added support for multiple test verbs ([#724](https://github.com/opensearch-project/opensearch-api-specification/pull/724))
 - Added support for using a certificate and key in tests ([#731](https://github.com/opensearch-project/opensearch-api-specification/pull/731))
-- Added `GET /_plugins/_ml/models/{model_id}`, `POST /_plugins/_ml/models/_search`, `PUT /_plugins/_ml/models/{model_id}`, `POST /_plugins/_ml/models/{model_id}/_unload`, `POST /_plugins/_ml/models/_unload`, `POST /_plugins/_ml/models/_undeploy`, `POST /_plugins/_ml/models/_upload`,`POST /_plugins/_ml/models/{model_id}/_load`, and `POST /_plugins/_ml/models/meta` ([#733](https://github.com/opensearch-project/opensearch-api-specification/pull/733))

 ### Removed
 - Removed unsupported `_common.mapping:SourceField`'s `mode` field and associated `_common.mapping:SourceFieldMode` enum ([#652](https://github.com/opensearch-project/opensearch-api-specification/pull/652))
