+        * Using package import from `run-haskell-module` by default.
+        * Expose commonly used functions for:
+            - normalizing Haskell type names,
+            - formatting JSON Autotype types in Haskell
+
     3.0.4  Mar 2020
         * Do not try to test compilation when module is written to stdout.
         * Update lens dependency bounds
