**New Features**

- SOCKS Proxy Support! (requires PySocks; $ pip install requests[socks])

**Miscellaneous**

- Updated bundled urllib3 to 1.15.1.

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

**Improvements**

- Change built-in CaseInsensitiveDict (used for headers) to use OrderedDict
as its underlying datastore.

**Bugfixes**

- Don't use redirect_cache if allow_redirects=False
- When passed objects that throw exceptions from ``tell()``, send them via
chunked transfer encoding instead of failing.
- Raise a ProxyError for proxy related connection issues.

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

**Bugfixes**

- Resolve regression introduced in 2.9.0 that made it impossible to send binary
strings as bodies in Python 3.
- Fixed errors when calculating cookie expiration dates in certain locales.

**Miscellaneous**

- Updated bundled urllib3 to 1.13.1.

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

**Minor Improvements** (Backwards compatible)

- The ``verify`` keyword argument now supports being passed a path to a
directory of CA certificates, not just a single-file bundle.
- Warnings are now emitted when sending files opened in text mode.
- Added the 511 Network Authentication Required status code to the status code
registry.

**Bugfixes**

- For file-like objects that are not seeked to the very beginning, we now
send the content length for the number of bytes we will actually read, rather
than the total size of the file, allowing partial file uploads.
- When uploading file-like objects, if they are empty or have no obvious
content length we set ``Transfer-Encoding: chunked`` rather than
``Content-Length: 0``.
- We correctly receive the response in buffered mode when uploading chunked
bodies.
- We now handle being passed a query string as a bytestring on Python 3, by
decoding it as UTF-8.
- Sessions are now closed in all cases (exceptional and not) when using the
functional API rather than leaking and waiting for the garbage collector to
clean them up.
- Correctly handle digest auth headers with a malformed ``qop`` directive that
contains no token, by treating it the same as if no ``qop`` directive was
provided at all.
- Minor performance improvements when removing specific cookies by name.

**Miscellaneous**

- Updated urllib3 to 1.13.

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

**Bugfixes**

- Update certificate bundle to match ``certifi`` 2015.9.6.2's weak certificate
bundle.
- Fix a bug in 2.8.0 where requests would raise ``ConnectTimeout`` instead of
``ConnectionError``
- When using the PreparedRequest flow, requests will now correctly respect the
``json`` parameter. Broken in 2.8.0.
- When using the PreparedRequest flow, requests will now correctly handle a
Unicode-string method name on Python 2. Broken in 2.8.0.

**Minor Improvements** (Backwards Compatible)

- Requests now supports per-host proxies. This allows the ``proxies``
dictionary to have entries of the form
``{'<scheme>://<hostname>': '<proxy>'}``. Host-specific proxies will be used
in preference to the previously-supported scheme-specific ones, but the
previous syntax will continue to work.
- ``Response.raise_for_status`` now prints the URL that failed as part of the
exception message.
- ``requests.utils.get_netrc_auth`` now takes an ``raise_errors`` kwarg,
defaulting to ``False``. When ``True``, errors parsing ``.netrc`` files cause
exceptions to be thrown.
- Change to bundled projects import logic to make it easier to unbundle
requests downstream.
- Changed the default User-Agent string to avoid leaking data on Linux: now
contains only the requests version.

**Bugfixes**

- The ``json`` parameter to ``post()`` and friends will now only be used if
neither ``data`` nor ``files`` are present, consistent with the
documentation.
- We now ignore empty fields in the ``NO_PROXY`` environment variable.
- Fixed problem where ``httplib.BadStatusLine`` would get raised if combining
``stream=True`` with ``contextlib.closing``.
- Prevented bugs where we would attempt to return the same connection back to
the connection pool twice when sending a Chunked body.
- Miscellaneous minor internal changes.
- Digest Auth support is now thread safe.

**Updates**

- Updated urllib3 to 1.12.
