 - Added `ENABLE_DATETIME_INDEX_FILTERING` environment variable to enable datetime-based index selection using collection IDs. When enabled, the system creates indexes with UUID-based names and manages them through time-based aliases. Default is `false`.

 ### Added
+
 - Added support for dynamically-generated queryables based on Elasticsearch/OpenSearch mappings, with extensible metadata augmentation [#351](https://github.com/stac-utils/stac-fastapi-elasticsearch-opensearch/pull/351)
 - Included default queryables configuration for seamless integration. [#351](https://github.com/stac-utils/stac-fastapi-elasticsearch-opensearch/pull/351)
 - Added support for high-performance direct response mode for both Elasticsearch and Opensearch backends, controlled by the `ENABLE_DIRECT_RESPONSE` environment variable. When enabled (`ENABLE_DIRECT_RESPONSE=true`), endpoints return Starlette Response objects directly, bypassing FastAPI's jsonable_encoder and Pydantic serialization for significantly improved performance on large search responses. **Note:** In this mode, all FastAPI dependencies (including authentication, custom status codes, and validation) are disabled for all routes. Default is `false` for safety. A warning is logged at startup if enabled. See [issue #347](https://github.com/stac-utils/stac-fastapi-elasticsearch-opensearch/issues/347) and [PR #359](https://github.com/stac-utils/stac-fastapi-elasticsearch-opensearch/pull/359).
 - Added robust tests for the `ENABLE_DIRECT_RESPONSE` environment variable, covering both Elasticsearch and OpenSearch backends. Tests gracefully handle missing backends by attempting to import both configs and skipping if neither is available. [#359](https://github.com/stac-utils/stac-fastapi-elasticsearch-opensearch/pull/359)
 
 ### Changed
+
 - Refactored database logic to reduce duplication [#351](https://github.com/stac-utils/stac-fastapi-elasticsearch-opensearch/pull/351)
 - Replaced `fastapi-slim` with `fastapi` dependency [#351](https://github.com/stac-utils/stac-fastapi-elasticsearch-opensearch/pull/351)
 - Changed minimum Python version to 3.9 [#354](https://github.com/stac-utils/stac-fastapi-elasticsearch-opensearch/pull/354)

 - Refactored all boolean environment variable parsing in both Elasticsearch and OpenSearch backends to use the shared `get_bool_env` utility. This ensures robust and consistent handling of environment variables such as `ES_USE_SSL`, `ES_HTTP_COMPRESS`, and `ES_VERIFY_CERTS` across both backends. [#359](https://github.com/stac-utils/stac-fastapi-elasticsearch-opensearch/pull/359)
 
 ### Fixed
+
 - Improved performance of `mk_actions` and `filter-links` methods [#351](https://github.com/stac-utils/stac-fastapi-elasticsearch-opensearch/pull/351)
 - Fixed inheritance relating to BaseDatabaseSettings and ApiBaseSettings [#355](https://github.com/stac-utils/stac-fastapi-elasticsearch-opensearch/pull/355)
 - Fixed delete_item and delete_collection methods return types [#355](https://github.com/stac-utils/stac-fastapi-elasticsearch-opensearch/pull/355)
