Release Notes

urllib3/urllib3 (urllib3)

v1.26.16

Compare Source

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

• Fixed thread-safety issue where accessing a PoolManager with many distinct origins
  would cause connection pools to be closed while requests are in progress (#&#8203;2954 <https://github.com/urllib3/urllib3/pull/2954>_)

v1.26.15

Compare Source

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

• Fix socket timeout value when HTTPConnection is reused (#&#8203;2645 <https://github.com/urllib3/urllib3/issues/2645>__)
• Remove "!" character from the unreserved characters in IPv6 Zone ID parsing
  (#&#8203;2899 <https://github.com/urllib3/urllib3/issues/2899>__)
• Fix IDNA handling of '\x80' byte (#&#8203;2901 <https://github.com/urllib3/urllib3/issues/2901>__)

v1.26.14

Compare Source

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

• Fixed parsing of port 0 (zero) returning None, instead of 0. (#&#8203;2850 <https://github.com/urllib3/urllib3/issues/2850>__)
• Removed deprecated getheaders() calls in contrib module. Fixed the type hint of PoolKey.key_retries by adding bool to the union. (#&#8203;2865 <https://github.com/urllib3/urllib3/issues/2865>__)

v1.26.13

Compare Source

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

• Deprecated the HTTPResponse.getheaders() and HTTPResponse.getheader() methods.
• Fixed an issue where parsing a URL with leading zeroes in the port would be rejected
  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

Compare Source

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

• Added extra message to urllib3.exceptions.ProxyError when urllib3 detects that
  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

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

• 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 thread-safety issue where accessing a PoolManager with many distinct origins
  would cause connection pools to be closed while requests are in progress (#&#8203;2954 <https://github.com/urllib3/urllib3/pull/2954>_)

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)
