1.8.0rc1 (2018-01-01)
---------------------

Compatibility
~~~~~~~~~~~~~

- WebOb is no longer officially supported on Python 3.3 which was EOL'ed on
  2017-09-29.

Backwards Incompatibilities
~~~~~~~~~~~~~~~~~~~~~~~~~~~

- Many changes have been made to the way WebOb does Accept handling, not just
  for the Accept header itself, but also for Accept-Charset, Accept-Encoding
  and Accept-Language. This was a `Google Summer of Code
  <https://developers.google.com/open-source/gsoc/>`_ project completed by
  Whiteroses (https://github.com/whiteroses). Many thanks to Google for running
  GSoC, the Python Software Foundation for organising and a huge thanks to Ira
  for completing the work. See https://github.com/Pylons/webob/pull/338 and
  https://github.com/Pylons/webob/pull/335. Documentation is available at
  https://docs.pylonsproject.org/projects/webob/en/master/api/webob.html

- When calling a ``@wsgify`` decorated function, the default arguments passed
  to ``@wsgify`` are now used when called with the request, and not as a
  `start_response`

  .. code::

     def hello(req, name):
         return "Hello, %s!" % name
     app = wsgify(hello, args=("Fred",))

     req = Request.blank('/')
     resp = req.get_response(app)  # => "Hello, Fred"
     resp2 = app(req) # => "Hello, Fred"

  Previously the ``resp2`` line would have failed with a ``TypeError``. With
  this change there is no way to override the default arguments with no
  arguments. See https://github.com/Pylons/webob/pull/203

- When setting ``app_iter`` on a ``Response`` object the ``content_md5`` header
  is no longer cleared. This behaviour is odd and disallows setting the
  ``content_md5`` and then returning an iterator for chunked content encoded
  responses. See https://github.com/Pylons/webob/issues/86

Experimental Features
~~~~~~~~~~~~~~~~~~~~~

These features are experimental and may change at any point in the future.

- The cookie APIs now have the ability to set the SameSite attribute on a
  cookie in both ``webob.cookies.make_cookie`` and
  ``webob.cookies.CookieProfile``. See https://github.com/Pylons/webob/pull/255

Bugfix
~~~~~~

- Request.host_url, Request.host_port, Request.domain correctly parse IPv6 Host
  headers as provided by a browser. See
  https://github.com/Pylons/webob/pull/332

- Request.authorization would raise ValueError for unusual or malformed header
  values. See https://github.com/Pylons/webob/issues/231

- Allow unnamed fields in form data to be properly transcoded when calling
  request.decode with an alternate encoding. See
  https://github.com/Pylons/webob/pull/309

- ``Response.__init__`` would discard ``app_iter`` when a ``Response`` had no
  body, this would cause issues when ``app_iter`` was an object that was tied
  to the life-cycle of a web application and had to be properly closed.
  ``app_iter`` is more advanced API for ``Response`` and thus even if it
  contains a body and is thus against the HTTP RFC's, we should let the users
  shoot themselves by returning a body. See
  https://github.com/Pylons/webob/issues/305
