  even when the port number after removing the zeroes was valid.
• Fixed a deprecation warning when using cryptography v39.0.0.
• Removed the <4 in the Requires-Python packaging metadata field.

v1.26.12

Compare Source

====================

• Deprecated the urllib3[secure] extra and the urllib3.contrib.pyopenssl module.
  Both will be removed in v2.x. See this GitHub issue <https://github.com/urllib3/urllib3/issues/2680>_
  for justification and info on how to migrate.

v1.26.11

Compare Source

====================

• Fixed an issue where reading more than 2 GiB in a call to HTTPResponse.read would
  raise an OverflowError on Python 3.9 and earlier.

v1.26.10

Compare Source

====================

• Removed support for Python 3.5
• Fixed an issue where a ProxyError recommending configuring the proxy as HTTP
  instead of HTTPS could appear even when an HTTPS proxy wasn't configured.

v1.26.9

Compare Source

===================

• Changed urllib3[brotli] extra to favor installing Brotli libraries that are still
  receiving updates like brotli and brotlicffi instead of brotlipy.
  This change does not impact behavior of urllib3, only which dependencies are installed.
• Fixed a socket leaking when HTTPSConnection.connect() raises an exception.
• Fixed server_hostname being forwarded from PoolManager to HTTPConnectionPool
  when requesting an HTTP URL. Should only be forwarded when requesting an HTTPS URL.

v1.26.8

  a proxy is configured to use HTTPS but the proxy itself appears to only use HTTP.
• Added a mention of the size of the connection pool when discarding a connection due to the pool being full.
• Added explicit support for Python 3.11.
• Deprecated the Retry.MAX_BACKOFF class property in favor of Retry.DEFAULT_MAX_BACKOFF
  to better match the rest of the default parameter names. Retry.MAX_BACKOFF is removed in v2.0.
• Changed location of the vendored ssl.match_hostname function from urllib3.packages.ssl_match_hostname
  to urllib3.util.ssl_match_hostname to ensure Python 3.10+ compatibility after being repackaged
  by downstream distributors.
• Fixed absolute imports, all imports are now relative.

v1.26.7

Compare Source

===================

• Fixed a bug with HTTPS hostname verification involving IP addresses and lack
  of SNI. (Issue #​2400)
• Fixed a bug where IPv6 braces weren't stripped during certificate hostname
  matching. (Issue #​2240)

v1.26.6

Compare Source

===================

• Deprecated the urllib3.contrib.ntlmpool module. urllib3 is not able to support
  it properly due to reasons listed in this issue <https://github.com/urllib3/urllib3/issues/2282>_.
  If you are a user of this module please leave a comment.
• Changed HTTPConnection.request_chunked() to not erroneously emit multiple
  Transfer-Encoding headers in the case that one is already specified.
• Fixed typo in deprecation message to recommend Retry.DEFAULT_ALLOWED_METHODS.

v1.26.5

Compare Source

===================

• Fixed deprecation warnings emitted in Python 3.10.
• Updated vendored six library to 1.16.0.
• Improved performance of URL parser when splitting
  the authority component.

v1.26.4

Compare Source

Compare Source

===================

  Starting in urllib3 v2.0: Connections that receive a DeprecationWarning will fail

• Deprecated Retry options Retry.DEFAULT_METHOD_WHITELIST, Retry.DEFAULT_REDIRECT_HEADERS_BLACKLIST

  the same socket.send() call (Pull #​1906)

  into an urllib3.exceptions.SSLError (Pull #​1939)

v1.25.11

Compare Source

  in the HTTP date format. The HTTP date was parsed as the local timezone
  rather than accounting for the timezone in the HTTP date (typically
  UTC) (Pull #​1932, Pull #​1935, Pull #​1938, Pull #​1949)

• Fix issue where an error would be raised when the SSLKEYLOGFILE

Compare Source

====================

• Added support for SSLKEYLOGFILE environment variable for
  logging TLS session keys with use with programs like
  Wireshark for decrypting captured web traffic (Pull #​1867)

• Avoid hasattr call in BrotliDecoder.decompress() (Pull #​1858)

v1.25.9

Compare Source

===================

• Added InvalidProxyConfigurationWarning which is raised when
  erroneously specifying an HTTPS proxy URL. urllib3 doesn't currently
  support connecting to HTTPS proxies but will soon be able to
  and we would like users to migrate properly without much breakage.

  See this GitHub issue <https://github.com/urllib3/urllib3/issues/1850>_
  for more information on how to fix your proxy config. (Pull #​1851)

• Drain connection after PoolManager redirect (Pull #​1817)

v1.25.4

Compare Source

===================
