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

**Improvements**

- Warn user about possible slowdown when using cryptography version < 1.3.4

would raise an ``IOError``.
- Fixed issue with unexpected ``ImportError`` on windows system which do not support ``winreg`` module.

**Note**: code that was written to import against the ``requests.packages``
namespace previously will have to import code that rests at this module-level
now.

For example::

 from requests.packages.urllib3.poolmanager import PoolManager

Will need to be re-written to be::

 from requests.packages import urllib3
 urllib3.poolmanager.PoolManager

Or, even better::

 from urllib3.poolmanager import PoolManager

2.16.0

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

- Unvendor ALL the things!

2.15.1

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

- Everyone makes mistakes.

2.14.1

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

**Bugfixes**

- Changed the dependency markers to widen compatibility with older pip
releases.

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.

- 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.
