 # 0.20.4 (06-01-2017)
 
 * **(breaking change)** A type that wants to convert itself to JSON now must override `to_json(builder : JSON::Builder)` instead of `to_json(io : IO)`. The same is true for custom JSON converters. If you are using `JSON.mapping` then your code will continue to work without changes.
