  ## [Unreleased]
  +
  +Probably the last release that `curly` is considered experimental.

  ### Breaking Change
  - `curly` (and `curly.<method>`) is now able to automatically parse the response body based on the content-type header of the response. [#240](https://github.com/JCMais/node-libcurl/issues/240)
  Default parsers for `application/json` (calls `JSON.parse`) and `text/*` (converts the raw `Buffer` to a string with `utf8` encoding) were added. This means that for responses without a matching content-type the raw `Buffer` will be returned. This is different from the previous behavior where a string would always be returned.
