 and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).
 
+## [Unreleased] - TBD
+
+### Changed
+
+- Basic Spatial Operators in CQL2 now only requires BBOX and POINT support, so the text
+  and examples were updated to account for this.
+
 ## [v1.0.0-rc.2] - 2022-11-01
 
+### Changed
+
 - Update language on catalog-level queryables
 - Fix several examples
