 ### Patches
 
-- **Fuzzy comparisons on lists** ([#415](https://github.com/Materials-Consortia/OPTIMADE/pull/415))
+- **Fuzzy comparisons on lists** ([#415](https://github.com/Materials-Consortia/OPTIMADE/pull/415)):
 String comparisons like `CONTAINS`, `STARTS WITH` and `ENDS WITH` are now compatible with list filter operations like `HAS`, `HAS ALL` etc.
 - **Boolean values** ([#348](https://github.com/Materials-Consortia/OPTIMADE/pull/348)):
 [Boolean values](https://github.com/Materials-Consortia/OPTIMADE/blob/v1.2.0/optimade.rst#comparisons-of-boolean-values) were overlooked in the first version of the filter grammar as no OPTIMADE fields required them.
 This functionality has been introduced for boolean fields using the syntax `TRUE` and `FALSE`.
 Only strict equality (`=`) and inequality (`!=`) comparisons on individual fields are supported.
 - **Compatibility with JSON:API v1.1** ([#461](https://github.com/Materials-Consortia/OPTIMADE/pull/461)): References to JSON:API v1.0 have been updated to v1.1.
