package of urllib3, you may need to tweak things. (Issue #415)
Unverified HTTPS requests will trigger a warning on the first request. See
our new security documentation for details.

All raised exceptions should now wrapped in a
urllib3.exceptions.HTTPException-extending exception. (Issue #326)
All errors during a retry-enabled request should be wrapped in
urllib3.exceptions.MaxRetryError, including timeout-related exceptions
which were previously exempt. Underlying error is accessible from the
.reason propery. (Issue #326)
urllib3.exceptions.ConnectionError renamed to
urllib3.exceptions.ProtocolError. (Issue #326)

urllib3.exceptions.ProtocolError. (Issue #418)

(Issues #366, #369)

Fix urllib3.util not being included in the package.
Fix AppEngine bug of HTTPS requests going out as HTTP. (Issue #356)

for the test suite. (Issue #362)
Added support for specifying source_address. (Issue #352)
Improved url parsing in urllib3.util.parse_url (properly parse '@' in
username, and blank ports like 'hostname:').
New urllib3.connection module which contains all the HTTPConnection
Several urllib3.util.Timeout-related fixes. Also changed constructor
signature to a more sensible order. [Backwards incompatible]
(Issues #252, #262, #263)
Use backports.ssl_match_hostname if it's installed. (Issue #274)
Added .tell() method to urllib3.response.HTTPResponse which
returns the number of bytes read so far. (Issue #277)
Support for platforms without threading. (Issue #289)
Expand default-port comparison in HTTPConnectionPool.is_same_host
to allow a pool with no specified port to be considered equal to to an
HTTP/HTTPS url with port 80/443 explicitly provided. (Issue #305)
Improved default SSL/TLS settings to avoid vulnerabilities.
Fixed urllib3.poolmanager.ProxyManager not retrying on connect errors.
Disable Nagle's Algorithm on the socket for non-proxies. A subset of requests
will send the entire HTTP request ~200 milliseconds faster; however, some of
the resulting TCP packets will be smaller. (Issue #254)
Increased maximum number of SubjectAltNames in urllib3.contrib.pyopenssl
from the default 64 to 1024 in a single certificate. (Issue #318)
Headers are now passed and stored as a custom

Improved IPv6 support. (Issue #203)
Contrib: Optional SNI support for Py2 using PyOpenSSL. (Issue #156)
ProxyManager automatically adds Host: ... header if not given.
Improved SSL-related code. cert_req now optionally takes a string like
"REQUIRED" or "NONE". Same with ssl_version takes strings like "SSLv23"
The string values reflect the suffix of the respective constant variable.
Vendored socksipy now based on Anorov's fork which handles unexpectedly
closed proxy connections and larger read buffers. (Issue #135)
Ensure the connection is closed if no data is received, fixes connection leak
on some platforms. (Issue #133)
Added SNI support for SSL/TLS connections on Py32+. (Issue #89)
Tests fixed to be compatible with Py26 again. (Issue #125)

Exceptions are now pickleable, with tests. (Issue #101)
Fixed default headers not getting passed in some cases. (Issue #99)
Treat "content-encoding" header value as case-insensitive, per RFC 2616
Section 3.5. (Issue #110)
"Connection Refused" SocketErrors will get retried rather than raised.
Updated vendored six, no longer overrides the global six module
namespace. (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.
Don't assume Content-Type: text/plain for multi-part encoding parameters
that are not files. (Issue #111)
Pass strict param down to httplib.HTTPConnection. (Issue #122)
Added mechanism to verify SSL certificates by fingerprint (md5, sha1) or
against an arbitrary hostname (when connecting by IP or for misconfigured
servers). (Issue #140)
Streaming decompression support. (Issue #159)
Added urllib3.add_stderr_logger() for quickly enabling STDERR debug
logging in urllib3.
Native full URL parsing (including auth, path, query, fragment) available in
Built-in redirect will switch method to 'GET' if status code is 303.
urllib3.PoolManager strips the scheme and host before sending the request
uri. (Issue #8)
New urllib3.exceptions.DecodeError exception for when automatic decoding,
based on the Content-Type header, fails.

explicit connection closing on pool eviction. Added
99% -> 100% unit test coverage.
Minor AppEngine-related fixes.
Switched from mimetools.choose_boundary to uuid.uuid4().
Improved url parsing. (Issue #73)
IPv6 url support. (Issue #72)
Removed pre-1.0 deprecated API.
Refactored helpers into a urllib3.util submodule.

values. (Issue #48)

Python 3. (Issue #53)
AppEngine support with Py27. (Issue #61)
Minor encode_multipart_formdata fixes related to Python 3 strings vs
Fixed packaging bug of not shipping test-requirements.txt. (Issue #47)
Fixed another bug related to when ssl module is not available. (Issue #41)
Location parsing errors now raise urllib3.exceptions.LocationParseError
which inherits from ValueError.
Added Python 3 support (tested on 3.2.2)
Dropped Python 2.5 support (tested on 2.6.7, 2.7.2)
Use select.poll instead of select.select for platforms that support
Use Queue.LifoQueue instead of Queue.Queue for more aggressive
connection reusing. Configurable by overriding ConnectionPool.QueueCls.
Fixed ImportError during install when ssl module is not available.
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. Removed extraneous unsupported dummyserver testing backends.
Added socket-level tests.
More tests. Achievement Unlocked: 99% Coverage.
Refactored dummyserver to its own root namespace module (used for

Py32's ssl_match_hostname. (Issue #25)

Fixed decode_content being ignored when set through urlopen. (Issue
Fixed timeout-related bugs. (Issues #17, #23)
Fixed typo in VerifiedHTTPSConnection which would only present as a bug if
you're using the object manually. (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.
Fixed a bug where the same connection would get returned into the pool twice,
causing extraneous "HttpConnectionPool is full" log warnings.
Added PoolManager with LRU expiration of connections (tested and
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 urllib3.readthedocs.org.
