0.22.7

Bug Fixes

• Adds support for generating JSON bodies for schemas where the root is an
  array. For example, given following array schema:

  type: array
  items:
    type: string
    example: Doe

  The parser will now generate a JSON body of ["Doe"] whereas in previous
  versions would've resulted in an empty array.

• Fixes parsing Swagger documents that contain properties called $ref.
  Previously the parser would attempt to dereference the property as would
  generically try to dereference any key in an object called $ref, as per the
  JSON Schema specification, references are only permitted when a schema type
  is expected.

  For example, the following is a schema which is trying to describe an object
  with a property called $ref, previously the parser would attempt to
  dereference $ref and crash in the process.

  type: object
  properties:
    $ref:
      type: string
      example: '#/definitions/User'
  required: ['$ref']

  There is a still an open known issue
  #235 that
  uses of $ref in a Swagger 2 document where the value a string will cause
  the parser to attempt to dereference it incorrectly when the $ref property
  is found on an object that does not support $ref as per the Swagger 2 and
  JSON Schema specifications.
