  (#134 - @robinnorth)
• Fixed: Support multiple select fields in form submissions.
  (#147 - @robinnorth)
• Fixed: Use the same options object in handle-response as in send-request. This way, pjax.state.options will also have the request options.
  (#148 - @BehindTheMath)
• Added: Move the XHR callback to a separate method, and trigger an error event if the response cannot be parsed.
  (#137 - @BehindTheMath)
• Added: TypeScript definitions.
  (#138 - @BehindTheMath)
• Added: replaceNode switch, as an alternative to the outerHTML switch.
  (#141 - @BehindTheMath)
• Added: X-PJAX-Selectors HTTP header. This is a serialized JSON array of selectors, taken from options.selectors. You can use this to send back only the elements that Pjax will use to switch, instead of sending the whole page.
  (#144 - @BehindTheMath)
• Added: An option to use FormData to submit forms.
  (#153 - @BehindTheMath)
