1.0.0.M20

• openapi-processor/openapi-processor-core#30 (core), preserve the "?" generic parameter of a mapping and pass it on to the generated api, e.g. a mapping like

  map:
    paths:
      /foo:
        parameters:
          - add: foo => io.openapiprocessor.Foo<?>

  does now generate

  void foo(Foo<?> foo);

  instead of

  void foo(Foo foo);

• #119 (core), primitive type could match a primitive type with format mapping, e.g. with the mapping

  openapi-processor-spring: v2
  
  map:
    types:
      - type: string:binary => io.openapiprocessor.Foo
  

  it was possible that a primitive string was mapped to io.openapiprocessor.Foo instead of java.lang.String

• (core) a ref loop with array items caused a NullPointerException

• updated openapi-processor-core to 1.3.0 (was 1.2.1)
