• Technical release

0.19.0

0.19.0 (2025-06-09)

• BREAKING FIX: json-transformer is now better at inferring en/decoders for :enum and :=. #1205
  • For example [:enum 1 2 3] gets encoded as a JSON number, not a string.
  • If you need the old behaviour, you can override the en/decoders using properties. See docs.
• Value generation: :+ and :* now support generator directives :gen/min, :gen/max as well as :min and :max schema directives #1208
• CLJS bundle size reduced #1211
• FIX: :default/fn now works in map entry properties in addition to schema properties #1209

0.18.0

0.18.0 (2025-05-12)

• BREAKING Output of parse now uses new malli.core.Tag and malli.core.Tags records for :orn, :multi, :altn, :catn etc. #1123 #1153
  • See Parsing and Unparsing for docs.
• BREAKING Swagger and JSON-Schema outputs now use . instead of / (encoded as ~1) as the separator. #1183
  • This will only affect you if you rely on the exact name of the schema
• Docs: elaborate optional-keys and required-keys #1117
• JSON Schema for :tuple now uses "prefixItems" #1151
• FIX: :path when explaining :ref errors #1106
• FIX: don't instrument functions with primitive type hints (like ^double), instead, emit a warning #1176
• FIX: :map-of and :map decode now retain the input map type (eg. sorted-map) #1189
• FIX: schemas and into-schemas are printed to the console and the REPL in CLJS the same way as they are in CLJ. #1186
• FIX: :merge and :union now work with 1 child. With no children, throw a clearer error. #1147
• FIX: default-value-transformer for :refs inside :maps #1145
• FIX: generator for empty? schema #1196
