 ## [2.0.0] - 2020-09-10
 
 ### Changed
+
 - Refactored into a 'composite' action which has following implications ([#4]):
   - Action runs slightly faster because there's no 'node' process in between (or io stream redirects).
   - Action has now just single `script` input, and you cannot "add" outputs other than automatic "result" and "error".
 
 ### Removed
+
 - All optional inputs - until "composite" refactor, they were used to pass workflow contexts to the action.
   It's no longer necessary, since 'composite' action can "grab" them on it's own.
 - Ability to set custom `outputs` from the script - now only `result` and `error` are set (as outlined in readme).
