Users who are using urllib3 version 1.17 or 1.18 along with + PyOpenSSL injection and OpenSSL 1.1.0 *must* upgrade to this version. This + release fixes a vulnerability whereby urllib3 in the above configuration + would silently fail to validate TLS certificates due to erroneously setting + invalid flags in OpenSSL's ``SSL_CTX_set_verify`` function. These erroneous + flags do not cause a problem in OpenSSL versions before 1.1.0, which + interprets the presence of any flag as requesting certificate validation. + + There is no PR for this patch, as it was prepared for simultaneous disclosure + and release. The master branch received the same fix in Pull #1010. + + +1.18 (2016-09-26) +----------------- + +* Fixed incorrect message for IncompleteRead exception.

(Issue #848) + +* Timeout can no longer be set as boolean, and must be greater than zero. + (Pull #924) + +* Removed pyasn1 and ndg-httpsclient from dependencies used for PyOpenSSL. We + now use cryptography and idna, both of which are already dependencies of + PyOpenSSL. (Pull #930) + +* Fixed infinite loop in ``stream`` when amt=None. (Issue #928) + +* Try to use the operating system's certificates when we are using an + ``SSLContext``. (Pull #941) + +* Updated cipher suite list to allow ChaCha20+Poly1305.

(Pull #958) + +* Removed the cipher suite fallback to allow HIGH ciphers. (Pull #958) + +* Implemented ``length_remaining`` to determine remaining content + to be read. (Pull #949) + +* Implemented ``enforce_content_length`` to enable exceptions when + incomplete data chunks are received. (Pull #949) + +* Dropped connection start, dropped connection reset, redirect, forced retry, + and new HTTPS connection log levels to DEBUG, from INFO.

(Issue #864) + +* Fixed signature of ``ConnectionPool.close`` so it can actually safely be + called by subclasses. (Issue #873) + +* Retain ``release_conn`` state across retries. (Issues #651, #866) + +* Add customizable ``HTTPConnectionPool.ResponseCls``, which defaults to + ``HTTPResponse`` but can be replaced with a subclass. (Issue #879) + + +1.15.1 (2016-04-11) +------------------- + +* Fix packaging to include backports module. (Issue #841) + + +1.15 (2016-04-06) +----------------- + +* Added Retry(raise_on_status=False). (Issue #720) + +* Always use setuptools, no more distutils fallback.

(Issue #113) + +* ``urllib3.exceptions.MaxRetryError`` contains a ``reason`` property holding + the exception that prompted the final retry. If ``reason is None`` then it + was due to a redirect. (Issue #92, #114) + +* Fixed ``PoolManager.urlopen()`` from not redirecting more than once. + (Issue #149) + +* Don't assume ``Content-Type: text/plain`` for multi-part encoding parameters + that are not files.

Configurable by overriding ``ConnectionPool.QueueCls``. + +* Fixed ``ImportError`` during install when ``ssl`` module is not available. + (Issue #41) + +* Fixed ``PoolManager`` redirects between schemes (such as HTTP -> HTTPS) not + completing properly. (Issue #28, uncovered by Issue #10 in v1.1) + +* Ported ``dummyserver`` to use ``tornado`` instead of ``webob`` + + ``eventlet``.

(Thanks pyos) + +* Made RecentlyUsedContainer (and consequently PoolManager) more thread-safe by + wrapping the access log in a mutex. (Thanks @christer) + +* Made RecentlyUsedContainer more dict-like (corrected ``__delitem__`` and + ``__getitem__`` behaviour), with tests. Shouldn't affect core urllib3 code. + + +1.0.1 (2011-10-10) +------------------ + +* Fixed a bug where the same connection would get returned into the pool twice, + causing extraneous "HttpConnectionPool is full" log warnings. + + +1.0 (2011-10-08) +---------------- + +* Added ``PoolManager`` with LRU expiration of connections (tested and + documented). +* Added ``ProxyManager`` (needs tests, docs, and confirmation that it works + with HTTPS proxies). +* Added optional partial-read support for responses when + ``preload_content=False``. You can now make requests and just read the headers + without loading the content. +* Made response decoding optional (default on, same as before). +* Added optional explicit boundary string for ``encode_multipart_formdata``. +* Convenience request methods are now inherited from ``RequestMethods``. Old + helpers like ``get_url`` and ``post_url`` should be abandoned in favour of + the new ``request(method, url, ...)``. +* Refactored code to be even more decoupled, reusable, and extendable. +* License header added to ``.py`` files. +* Embiggened the documentation: Lots of Sphinx-friendly docstrings in the code + and docs in ``docs/`` and on https://urllib3.readthedocs.io/. +* Embettered all the things! +* Started writing this file. + + +0.4.1 (2011-07-17) +------------------ + +* Minor bug fixes, code cleanup. + + +0.4 (2011-03-01) +---------------- + +* Better unicode support. +* Added ``VerifiedHTTPSConnection``. +* Added ``NTLMConnectionPool`` in contrib. +* Minor improvements. + + +0.3.1 (2010-07-13) +------------------ + +* Added ``assert_host_name`` optional parameter.
