filter_spatial: Clarify masking

CHANGELOG.md

@@ -12,6 +12,8 @@ and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0
 
 ### Fixed
 
+- `filter_bbox`, `load_collection`, `load_stac`: Clarified that the bounding box is reprojected to the CRS of the spatial data cube dimensions if required.
+- `filter_spatial`: Clarified that masking is applied using the given geometries. [#469](https://github.com/Open-EO/openeo-processes/issues/469)
 - `sqrt`: Clarified that NaN is returned for negative numbers.
