v2.32.3

Compare Source

Bugfixes

• Fixed bug breaking the ability to specify custom SSLContexts in sub-classes of
  HTTPAdapter. (#​6716)
• Fixed issue where Requests started failing to run on Python versions compiled
  without the ssl module. (#​6724)

v2.32.2

Compare Source

Deprecations

• To provide a more stable migration for custom HTTPAdapters impacted
  by the CVE changes in 2.32.0, we've renamed _get_connection to
  a new public API, get_connection_with_tls_context. Existing custom
  HTTPAdapters will need to migrate their code to use this new API.
  get_connection is considered deprecated in all versions of Requests>=2.32.0.

  A minimal (2-line) example has been provided in the linked PR to ease
  migration, but we strongly urge users to evaluate if their custom adapter
  is subject to the same issue described in CVE-2024-35195. (#​6710)

v2.32.1

Compare Source

Bugfixes

• Add missing test certs to the sdist distributed on PyPI.

v2.32.0

Compare Source

Security

• Fixed an issue where setting verify=False on the first request from a
  Session will cause subsequent requests to the same origin to also ignore
  cert verification, regardless of the value of verify.
  (GHSA-9wx4-h78v-vm56)

Improvements

• verify=True now reuses a global SSLContext which should improve
  request time variance between first and subsequent requests. It should
  also minimize certificate load time on Windows systems when using a Python
  version built with OpenSSL 3.x. (#​6667)
• Requests now supports optional use of character detection
  (chardet or charset_normalizer) when repackaged or vendored.
  This enables pip and other projects to minimize their vendoring
  surface area. The Response.text() and apparent_encoding APIs
  will default to utf-8 if neither library is present. (#​6702)

Bugfixes

• Fixed bug in length detection where emoji length was incorrectly
  calculated in the request content-length. (#​6589)
• Fixed deserialization bug in JSONDecodeError. (#​6629)
• Fixed bug where an extra leading / (path separator) could lead
  urllib3 to unnecessarily reparse the request URI. (#​6644)

Deprecations

• Requests has officially added support for CPython 3.12 (#​6503)
• Requests has officially added support for PyPy 3.9 and 3.10 (#​6641)
• Requests has officially dropped support for CPython 3.7 (#​6642)
• Requests has officially dropped support for PyPy 3.7 and 3.8 (#​6641)

Documentation

• Various typo fixes and doc improvements.

Packaging

• Requests has started adopting some modern packaging practices.
  The source files for the projects (formerly requests) is now located
  in src/requests in the Requests sdist. (#​6506)
• Starting in Requests 2.33.0, Requests will migrate to a PEP 517 build system
  using hatchling. This should not impact the average user, but extremely old
  versions of packaging utilities may have issues with the new packaging format.

v2.31.0

Compare Source

Security

• Versions of Requests between v2.3.0 and v2.30.0 are vulnerable to potential
  forwarding of Proxy-Authorization headers to destination servers when
  following HTTPS redirects.

  When proxies are defined with user info (https://user:pass@proxy:8080), Requests
  will construct a Proxy-Authorization header that is attached to the request to
  authenticate with the proxy.

  In cases where Requests receives a redirect response, it previously reattached
  the Proxy-Authorization header incorrectly, resulting in the value being
  sent through the tunneled connection to the destination server. Users who rely on
  defining their proxy credentials in the URL are strongly encouraged to upgrade
  to Requests 2.31.0+ to prevent unintentional leakage and rotate their proxy
  credentials once the change has been fully deployed.

  Users who do not use a proxy or do not supply their proxy credentials through
  the user information portion of their proxy URL are not subject to this
  vulnerability.

  Full details can be read in our Github Security Advisory
  and CVE-2023-32681.

v2.30.0

Compare Source

Dependencies

• ⚠️ Added support for urllib3 2.0. ⚠️

  This may contain minor breaking changes so we advise careful testing and
  reviewing https://urllib3.readthedocs.io/en/latest/v2-migration-guide.html
  prior to upgrading.

  Users who wish to stay on urllib3 1.x can pin to urllib3<2.

v2.29.0

Compare Source

Improvements

• Requests now defers chunked requests to the urllib3 implementation to improve
  standardization. (#​6226)
• Requests relaxes header component requirements to support bytes/str subclasses. (#​6356)

v2.28.2

Compare Source

Dependencies

• Requests now supports charset_normalizer 3.x. (#​6261)

Bugfixes

• Updated MissingSchema exception to suggest https scheme rather than http. (#​6188)
