Changes to Supported Platforms
------------------------------

- CPython 3.6 is now fully supported.
- Falcon appears to work well on PyPy3.5, but we are waiting until
  that platform is out of beta before officially supporting it.
- Support for both CPython 2.6 and Jython 2.7 is now deprecated and
  will be discontinued in Falcon 2.0.

New & Improved
--------------

- We added built-in resource representation serialization and
  deserialization, including input validation based on JSON Schema.
- URI template field converters are now supported. We expect to expand
  this feature over time.
- A new method, `get_param_as_datetime()`, was added to
  the ``Request`` class.
- A number of attributes were added to the ``Request`` class to
  make proxy information easier to consume. These include the
  `forwarded`, `forwarded_uri`, `forwarded_scheme`, `forwarded_host`,
  and `forwarded_prefix` attributes. The `prefix` attribute was also
  added as part of this work.
- A `referer` attribute was added to the ``Request`` class.
- We implemented `__repr__()` for ``Request``, ``Response``, and
  ``HTTPError`` to aid in debugging.
- A number of Internet media type constants were defined to make it
  easier to check and set content type headers.
- Several new 5xx error classes were implemented.

Fixed
-----

- If even a single cookie in the request to the server is malformed,
  none of the cookies will be parsed (all-or-nothing). Change the
  parser to simply skip bad cookies (best-effort).
- ``API`` instances are not pickleable. Modify the default router
  to fix this.
