1.8.5 (2019-01-03)
------------------

Warnings
~~~~~~~~

- Fixed one last remaining invalid escape sequence in a docstring.

1.8.4 (2018-11-11)
------------------

Bugfix
~~~~~~

- Response.content_type now accepts unicode strings on Python 2 and encodes
  them to latin-1. See https://github.com/Pylons/webob/pull/389 and
  https://github.com/Pylons/webob/issues/388

- Accept header classes now support a .copy() function that may be used to
  create a copy. This allows ``create_accept_header`` and other like functions
  to accept an pre-existing Accept header. See
  https://github.com/Pylons/webob/pull/386 and
  https://github.com/Pylons/webob/issues/385

Warnings
~~~~~~~~

- Some backslashes introduced with the new accept handling code were causing
  DeprecationWarnings upon compiling the source to pyc files, all of the
  backslashes have been reigned in as appropriate, and users should no longer
  see DeprecationWarnings for invalid escape sequence. See
  https://github.com/Pylons/webob/issues/384

1.8.3 (2018-10-14)
------------------

Bugfix
~~~~~~

- ``acceptparse.AcceptValidHeader``, ``acceptparse.AcceptInvalidHeader``, and
  ``acceptparse.AcceptNoHeader`` will now always ignore offers that do not
  match the required media type grammar when calling ``.acceptable_offers()``.
  Previous versions raised a ``ValueError`` for invalid offers in
  ``AcceptValidHeader`` and returned them as acceptable in the others.
  See https://github.com/Pylons/webob/pull/372

Feature
~~~~~~~

- Add Request.remote_host, exposing REMOTE_HOST environment variable.

- Added ``acceptparse.Accept.parse_offer`` to codify what types of offers
  are compatible with ``acceptparse.AcceptValidHeader.acceptable_offers``,
  ``acceptparse.AcceptMissingHeader.acceptable_offers``, and
  ``acceptparse.AcceptInvalidHeader.acceptable_offers``. This API also
  normalizes the offer with lowercased type/subtype and parameter names.
  See https://github.com/Pylons/webob/pull/376 and
  https://github.com/Pylons/webob/pull/379

1.8.2 (2018-06-05)
------------------

Bugfix
~~~~~~

- SameSite may now be passed as str or bytes to `Response.set_cookie` and
  `cookies.make_cookie`. This was an oversight as all other arguments would be
  correctly coerced before being serialized. See
  https://github.com/Pylons/webob/issues/361 and
  https://github.com/Pylons/webob/pull/362


1.8.1 (2018-04-10)
------------------

Bugfix
~~~~~~

- acceptparse.MIMEAccept which is deprecated in WebOb 1.8.0 made a backwards
  incompatible change that led to it raising on an invalid Accept header. This
  behaviour has now been reversed, as well as some other fixes to allow
  MIMEAccept to behave more like the old version. See
  https://github.com/Pylons/webob/pull/356

1.8.0 (2018-04-04)
------------------

Feature
~~~~~~~

- ``request.POST`` now supports any requests with the appropriate
  Content-Type. Allowing any HTTP method to access form encoded content,
  including DELETE, PUT, and others. See
  https://github.com/Pylons/webob/pull/352

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
~~~~~~

- Exceptions now use string.Template.safe_substitute rather than
  string.Template.substitute. The latter would raise for missing mappings, the
  former will simply not substitute the missing variable. This is safer in case
  the WSGI environ does not contain the keys necessary for the body template.
  See https://github.com/Pylons/webob/issues/345.

- 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
