  in Timeout defaults checking. (Issue #763)

1.13.1 (2015-12-18)
+++++++++++++++++++

* Fixed regression in IPv6 + SSL for match_hostname. (Issue #761)

1.13 (2015-12-14)
+++++++++++++++++

* Close connections more defensively on exception. (Issue #734)

* Adjusted ``read_chunked`` to handle gzipped, chunk-encoded bodies without
  repeatedly flushing the decoder, to function better on Jython. (Issue #743)

* Accept ``ca_cert_dir`` for SSL-related PoolManager configuration. (Issue #758)

1.12 (2015-09-03)
+++++++++++++++++

* Rely on ``six`` for importing ``httplib`` to work around
  conflicts with other Python 3 shims. (Issue #688)

* Add support for directories of certificate authorities, as supported by
  OpenSSL. (Issue #701)

* New exception: ``NewConnectionError``, raised when we fail to establish
  a new connection, usually ``ECONNREFUSED`` socket error.

1.11 (2015-07-21)
+++++++++++++++++

* When ``ca_certs`` is given, ``cert_reqs`` defaults to
  ``'CERT_REQUIRED'``. (Issue #650)

* ``pip install urllib3[secure]`` will install Certifi and
  PyOpenSSL as dependencies. (Issue #678)

* Made ``HTTPHeaderDict`` usable as a ``headers`` input value
  (Issues #632, #679)

* Added `urllib3.contrib.appengine \ 
<https://urllib3.readthedocs.org/en/latest/contrib.html#google-app-engine>`_
  which has an ``AppEngineManager`` for using ``URLFetch`` in a
  Google AppEngine environment. (Issue #664)

* Dev: Added test suite for AppEngine. (Issue #631)

* Fix performance regression when using PyOpenSSL. (Issue #626)

* Passing incorrect scheme (e.g. ``foo://``) will raise
  ``ValueError`` instead of ``AssertionError`` (backwards
  compatible for now, but please migrate). (Issue #640)

* Fix pools not getting replenished when an error occurs during a
  request using ``release_conn=False``. (Issue #644)

* Fix pool-default headers not applying for url-encoded requests
  like GET. (Issue #657)

* log.warning in Python 3 when headers are skipped due to parsing
  errors. (Issue #642)

* Close and discard connections if an error occurs during read.
  (Issue #660)

* Fix host parsing for IPv6 proxies. (Issue #668)

* Separate warning type SubjectAltNameWarning, now issued once
  per host. (Issue #671)

* Fix ``httplib.IncompleteRead`` not getting converted to
  ``ProtocolError`` when using ``HTTPResponse.stream()``
  (Issue #674)

1.10.4 (2015-05-03)

* Migrate tests to Tornado 4. (Issue #594)

* Append default warning configuration rather than overwrite.
  (Issue #603)

* Fix streaming decoding regression. (Issue #595)

* Fix chunked requests losing state across keep-alive connections.
  (Issue #599)

1.10.3 (2015-04-21)
+++++++++++++++++++

* Emit ``InsecurePlatformWarning`` when SSLContext object is missing.
  (Issue #558)

* Fix regression of duplicate header keys being discarded.
  (Issue #563)

* ``Response.stream()`` returns a generator for chunked responses.
  (Issue #560)

* Set upper-bound timeout when waiting for a socket in PyOpenSSL.
  (Issue #585)

* Work on platforms without `ssl` module for plain HTTP requests.
  (Issue #587)

* Stop relying on the stdlib's default cipher list. (Issue #588)

1.10.2 (2015-02-25)
+++++++++++++++++++

* Fix file descriptor leakage on retries. (Issue #548)

* Removed RC4 from default cipher list. (Issue #551)

* Header performance improvements. (Issue #544)

* Fix PoolManager not obeying redirect retry settings. (Issue #553)

1.10.1 (2015-02-10)
+++++++++++++++++++

* Pools can be used as context managers. (Issue #545)

* Don't re-use connections which experienced an SSLError. (Issue #529)
