Changelog

2.14.0

+++++++++++++

Improvements

• It is now possible to pass no_proxy as a key to the proxies
  dictionary to provide handling similar to the NO_PROXY environment
  variable.
• When users provide invalid paths to certificate bundle files or directories
  Requests now raises IOError, rather than failing at the time of the HTTPS
  request with a fairly inscrutable certificate validation error.
• The behavior of SessionRedirectMixin was slightly altered.
  resolve_redirects will now detect a redirect by calling
  get_redirect_target(response) instead of directly
  querying Response.is_redirect and Response.headers['location'].
  Advanced users will be able to process malformed redirects more easily.
• Changed the internal calculation of elapsed request time to have higher
  resolution on Windows.
• Added win_inet_pton as conditional dependency for the [socks] extra
  on Windows with Python 2.7.
• Changed the proxy bypass implementation on Windows: the proxy bypass
  check doesn't use forward and reverse DNS requests anymore
• URLs with schemes that begin with http but are not http or https
  no longer have their host parts forced to lowercase.

Bugfixes

• Much improved handling of non-ASCII Location header values in redirects.
  Fewer UnicodeDecodeErrors are encountered on Python 2, and Python 3 now
  correctly understands that Latin-1 is unlikely to be the correct encoding.
• If an attempt to seek file to find out its length fails, we now
  appropriately handle that by aborting our content-length calculations.
• Restricted HTTPDigestAuth to only respond to auth challenges made on 4XX
  responses, rather than to all auth challenges.
• Fixed some code that was firing DeprecationWarning on Python 3.6.
• The dismayed person emoticon (/o\\) no longer has a big head. I'm sure
  this is what you were all worrying about most.

Miscellaneous

• Updated bundled urllib3 to v1.21.1.
• Updated bundled chardet to v3.0.2.
• Updated bundled idna to v2.5.
• Updated bundled certifi to 2017.4.17.
