Release Notes

urllib3/urllib3

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

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

• Changed behavior of the default SSLContext when connecting to HTTPS proxy
  during HTTPS requests. The default SSLContext now sets check_hostname=True.

v1.26.3

Compare Source

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

• Fixed bytes and string comparison issue with headers (Pull #​2141)

• Changed ProxySchemeUnknown error message to be
  more actionable if the user supplies a proxy URL without
  a scheme. (Pull #​2107)

v1.26.2

Compare Source

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

• Fixed an issue where wrap_socket and CERT_REQUIRED wouldn't
  be imported properly on Python 2.7.8 and earlier (Pull #​2052)

v1.26.1

Compare Source

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

• Fixed an issue where two User-Agent headers would be sent if a
  User-Agent header key is passed as bytes (Pull #​2047)

v1.26.0

Compare Source

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

• NOTE: urllib3 v2.0 will drop support for Python 2.
  Read more in the v2.0 Roadmap <https://urllib3.readthedocs.io/en/latest/v2-roadmap.html>_.

• Added support for HTTPS proxies contacting HTTPS servers (Pull #​1923, Pull #​1806)

• Deprecated negotiating TLSv1 and TLSv1.1 by default. Users that
  still wish to use TLS earlier than 1.2 without a deprecation warning
  should opt-in explicitly by setting ssl_version=ssl.PROTOCOL_TLSv1_1 (Pull #​2002)
  Starting in urllib3 v2.0: Connections that receive a DeprecationWarning will fail

• Deprecated Retry options Retry.DEFAULT_METHOD_WHITELIST, Retry.DEFAULT_REDIRECT_HEADERS_BLACKLIST
  and Retry(method_whitelist=...) in favor of Retry.DEFAULT_ALLOWED_METHODS,
  Retry.DEFAULT_REMOVE_HEADERS_ON_REDIRECT, and Retry(allowed_methods=...)
  (Pull #​2000) Starting in urllib3 v2.0: Deprecated options will be removed

• Added default User-Agent header to every request (Pull #​1750)

• Added urllib3.util.SKIP_HEADER for skipping User-Agent, Accept-Encoding,
  and Host headers from being automatically emitted with requests (Pull #​2018)

• Collapse transfer-encoding: chunked request data and framing into
  the same socket.send() call (Pull #​1906)

• Send http/1.1 ALPN identifier with every TLS handshake by default (Pull #​1894)

• Properly terminate SecureTransport connections when CA verification fails (Pull #​1977)

• Don't emit an SNIMissingWarning when passing server_hostname=None
  to SecureTransport (Pull #​1903)

• Disabled requesting TLSv1.2 session tickets as they weren't being used by urllib3 (Pull #​1970)

• Suppress BrokenPipeError when writing request body after the server
  has closed the socket (Pull #​1524)

• Wrap ssl.SSLError that can be raised from reading a socket (e.g. "bad MAC")
  into an urllib3.exceptions.SSLError (Pull #​1939)

v1.25.11

Compare Source

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

• Fix retry backoff time parsed from Retry-After header when given
  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
  environment variable was set to the empty string. Now SSLContext.keylog_file
  is not set in this situation (Pull #​2016)

v1.25.10

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)

• Fixed loading of SecureTransport libraries on macOS Big Sur
  due to the new dynamic linker cache (Pull #​1905)

• Collapse chunked request bodies data and framing into one
  call to send() to reduce the number of TCP packets by 2-4x (Pull #​1906)

• Don't insert None into ConnectionPool if the pool
  was empty when requesting a connection (Pull #​1866)

• 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)

• Ensure load_verify_locations raises SSLError for all backends (Pull #​1812)

• Rename VerifiedHTTPSConnection to HTTPSConnection (Pull #​1805)

• Allow the CA certificate data to be passed as a string (Pull #​1804)

• Raise ValueError if method contains control characters (Pull #​1800)

• Add __repr__ to Timeout (Pull #​1795)
