 ## Upcoming breaking change!
 
 - For backward compatibility reasons `-zip` return a cons-cell instead of a list
   with two elements when called on two lists. This is a clunky API, and in an
   upcoming 3.0 release of Dash it will always return a list. If you rely on the
-  cons-cell return value, use `-zip-pair` instead.
