 - Added logging to bulk insertion methods to provide detailed feedback on errors encountered during operations. [#364](https://github.com/stac-utils/stac-fastapi-elasticsearch-opensearch/pull/364)
 - Introduced the `RAISE_ON_BULK_ERROR` environment variable to control whether bulk insertion methods raise exceptions on errors (`true`) or log warnings and continue processing (`false`). [#364](https://github.com/stac-utils/stac-fastapi-elasticsearch-opensearch/pull/364)
 - Added code coverage reporting to the test suite using pytest-cov. [#87](https://github.com/stac-utils/stac-fastapi-elasticsearch-opensearch/issues/87)
+- Introduced the `DATABASE_REFRESH` environment variable to control whether database operations refresh the index immediately after changes. If set to `true`, changes will be immediately searchable. If set to `false`, changes may not be immediately visible but can improve performance for bulk operations. [#370](https://github.com/stac-utils/stac-fastapi-elasticsearch-opensearch/pull/370)
 
 ### Changed
 
 - Updated dynamic mapping for items to map long values to double versus float. [#326](https://github.com/stac-utils/stac-fastapi-elasticsearch-opensearch/pull/326)
 - Extended Datetime Search to search on start_datetime and end_datetime as well as datetime fields. [#182](https://github.com/stac-utils/stac-fastapi-elasticsearch/pull/182)
 - Changed item update operation to use Elasticsearch index API instead of delete and create for better efficiency and atomicity. [#75](https://github.com/stac-utils/stac-fastapi-elasticsearch-opensearch/issues/75)
 - Bulk insertion via `BulkTransactionsClient` now strictly validates all STAC Items using the Pydantic model before insertion. Any invalid item will immediately raise a `ValidationError`, ensuring consistent validation with single-item inserts and preventing invalid STAC Items from being stored. This validation is enforced regardless of the `RAISE_ON_BULK_ERROR` setting. [#368](https://github.com/stac-utils/stac-fastapi-elasticsearch-opensearch/pull/368)
-
+- Refactored CRUD methods in `TransactionsClient` to use the `_resolve_refresh` helper method for consistent and reusable handling of the `refresh` parameter. [#370](https://github.com/stac-utils/stac-fastapi-elasticsearch-opensearch/pull/370)
 
 ### Fixed
 
 - Refactored `create_item` and `update_item` methods to share unified logic, ensuring consistent conflict detection, validation, and database operations. [#368](https://github.com/stac-utils/stac-fastapi-elasticsearch-opensearch/pull/368)
+- Fixed an issue where some routes were not passing the `refresh` parameter from `kwargs` to the database logic, ensuring consistent behavior across all CRUD operations. [#370](https://github.com/stac-utils/stac-fastapi-elasticsearch-opensearch/pull/370)
