v0.12.1

• Fixed. additionalPropertyForOperation() and
  mediaTypeMismatchForOperation() are built on the valid cases carrying the
  JSON media type their target was found under. Since 0.9.0 a body declared
  under several media types is generated under each of them, so a body
  offering application/json beside multipart/form-data or
  application/x-www-form-urlencoded produced draws with parts (or form
  fields) and no JSON value. The additional-property case then threw
  LogicException out of Gen::map() on a multipart draw and relabelled a
  form body as JSON on a form draw; the media-type case sent an empty body
  instead of the schema-valid one it promises to keep. ContractSuite weights
  both categories in, so OperationProperty over such an operation aborted
  with the exception rather than reporting anything about the document.
  malformedJsonForOperation() is deliberately left unfiltered: it replaces
  the body wholesale and never reads the drawn value, so every draw is as good
  a base as a JSON one.
