- Update to version 0.8.1:
* Fixed an issue with the memcache not working properly.
* Fixed an issue for Python 2.7.1 and higher that broke
copying of multidicts with :func:`copy.copy`.
* Changed hashing methodology of immutable ordered multi dicts
for a potential problem with alternative Python implementations.
- Changes from version 0.8:
* Removed data structure specific KeyErrors for a general
purpose :exc:`~werkzeug.exceptions.BadRequestKeyError`.
* Documented :meth:`werkzeug.wrappers.BaseRequest._load_form_data`.
* The routing system now also accepts strings instead of
dictionaries for the `query_args` parameter since we're only
passing them through for redirects.
* Werkzeug now automatically sets the content length immediately when
the :attr:`~werkzeug.wrappers.BaseResponse.data` attribute is set
for efficiency and simplicity reasons.
* The routing system will now normalize server names to lowercase.
* The routing system will no longer raise ValueErrors in case the
configuration for the server name was incorrect. This should make
deployment much easier because you can ignore that factor now.
* Fixed a bug with parsing HTTP digest headers. It rejected headers
with missing nc and nonce params.
* Proxy fix now also updates wsgi.url_scheme based on X-Forwarded-Proto.
* Added support for key prefixes to the redis cache.
* Added the ability to supress some auto corrections in the wrappers
that are now controlled via `autocorrect_location_header` and
`automatically_set_content_length` on the response objects.
* Werkzeug now uses a new method to check that the length of incoming
data is complete and will raise IO errors by itself if the server
fails to do so.
