  development server.

0.14

---

Released on December 31st 2017

• HTTP exceptions are now automatically caught by
  Request.application.
• Added support for edge as browser.
• Added support for platforms that lack SpooledTemporaryFile.
• Add support for etag handling through if-match
• Added support for the SameSite cookie attribute.
• Added werkzeug.wsgi.ProxyMiddleware
• Implemented has for NullCache
• get_multi on cache clients now returns lists all the time.
• Improved the watchdog observer shutdown for the reloader to not crash
  on exit on older Python versions.
• Added support for filename* filename attributes according to
  RFC 2231
• Resolved an issue where machine ID for the reloader PIN was not
  read accurately on windows.
• Added a workaround for syntax errors in init files in the reloader.
• Added support for using the reloader with console scripts on windows.
• The built-in HTTP server will no longer close a connection in cases
  where no HTTP body is expected (204, 204, HEAD requests etc.)
• The EnvironHeaders object now skips over empty content type and
  lengths if they are set to falsy values.
• Werkzeug will no longer send the content-length header on 1xx or
  204/304 responses.
• Cookie values are now also permitted to include slashes and equal
  signs without quoting.
• Relaxed the regex for the routing converter arguments.
• If cookies are sent without values they are now assumed to have an
  empty value and the parser accepts this. Previously this could have
  corrupted cookies that followed the value.
• The test Client and EnvironBuilder now support mimetypes like
  the request object does.
• Added support for static weights in URL rules.
• Better handle some more complex reloader scenarios where sys.path
  contained non directory paths.
• EnvironHeaders no longer raises weird errors if non string keys
  are passed to it.

Released on December 7th 2017

• Deprecate support for Python 2.6 and 3.3. CI tests will not run
  for these versions, and support will be dropped completely in the next
  version. (pallets/meta24_)
• Raise TypeError when port is not an integer. (1088_)
• Fully deprecate werkzeug.script. Use Click_ instead. (1090_)
• response.age is parsed as a timedelta. Previously, it was
  incorrectly treated as a datetime. The header value is an integer
  number of seconds, not a date string. (414_)
• Fix a bug in TypeConversionDict where errors are not propagated
  when using the converter. (1102_)
• Authorization.qop is a string instead of a set, to comply with
  RFC 2617. (984_)
• An exception is raised when an encoded cookie is larger than, by
  default, 4093 bytes. Browsers may silently ignore cookies larger than
  this. BaseResponse has a new attribute max_cookie_size and
  dump_cookie has a new argument max_size to configure this.
  (780, 1109)
• Fix a TypeError in werkzeug.contrib.lint.GuardedIterator.close.
  (1116_)
• BaseResponse.calculate_content_length now correctly works for
  Unicode responses on Python 3. It first encodes using
  iter_encoded. (705_)
• Secure cookie contrib works with string secret key on Python 3.
  (1205_)
• Shared data middleware accepts a list instead of a dict of static
  locations to preserve lookup order. (1197_)
• HTTP header values without encoding can contain single quotes.
  (1208_)
• The built-in dev server supports receiving requests with chunked
  transfer encoding. (1198_)
