+  control over the order that items are presented in the CDDL, at the cost

 ## O.3.5.0 -- 2024-11-25
 
 * Add support for constraints on references and generic references.
-* Add support for using references as range bounds. Note that this breaks 
-  backwards compatibility - because the range arguments are now more generic, 
-  additional hints are required to type literal numerics correctly. Typically 
-  this is most easily fixed by adding a call `int` for any numeric literals in
