 ## [Unreleased]
 
 ### Changed
 
+- Fixed a bug where missing 'copy()'' caused default queryables to be incorrectly enriched by results from previous queries. [#427](https://github.com/stac-utils/stac-fastapi-elasticsearch-opensearch/pull/449)
+- Removed non-generic attributes ('cloud_cover', 'cloud_shadow_percentage', 'nodata_pixel_percentage') not applicable to all collections (e.g., SAR data).[#427](https://github.com/stac-utils/stac-fastapi-elasticsearch-opensearch/pull/449)
+- Updated 'async_prep_create_item' to support OS item loading with multiple indices.[#427](https://github.com/stac-utils/stac-fastapi-elasticsearch-opensearch/pull/449)
 - updated `numReturned` & `numMatched` fields in itemCollection return to `numberReturned` & `numberMatched`. [#446](https://github.com/stac-utils/stac-fastapi-elasticsearch-opensearch/pull/446)

 - 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`.

 ## [v4.0.0] - 2025-04-23
 
 ### 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)

 - 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)
