    Object graphs and inline expressions on input properties

    You can now pass object graphs to step inputs as opposed to just scalar values

    "inputs": 
{    
  "Body": {
      "Value1": 1,
      "Value2": 2
  },
  "Headers": {
      "Content-Type": "application/json"
  }
},

    If you want to evaluate an expression for a given property of your object, simply prepend and @ and pass an expression string

    "inputs": 
{    
  "Body": {
      "@Value1": "data.MyValue * 2",
      "Value2": 5
  },
  "Headers": {
      "Content-Type": "application/json"
  }
},

    👌 Support for enum values on input properties

    If your step has an enum property, you can now just pass the string representation of the enum value and it will be automatically converted.

    Environment variables available in input expressions

    You can now access environment variables from within input expressions.
    usage:

    environment["VARIABLE_NAME"]
