requests

2.34.2 (2026-05-14)

• Moved headers input type back to Mapping to avoid invariance issues with MutableMapping and inferred dict types. Users calling Request.headers.update() may need to narrow typing in their code. (#7441)

2.34.1 (2026-05-13)

Bugfixes

• Widened json input type from dict and list to Mapping and Sequence. (#7436)
• Changed headers input type to MutableMapping and removed None from Request.headers typing to improve handling for users. (#7431)
• Response.reason moved from str | None to str to improve handling for users. (#7437)
• Fixed a bug where some bodies with custom __getattr__ implementations weren't being properly detected as Iterables. (#7433)

2.34.0 (2026-05-11)

Announcements

• Requests 2.34.0 introduces inline types, replacing those provided by typeshed. Public API types should be fully compatible with mypy, pyright, and ty. We believe types are comprehensive but if you find issues, please report them to the pinned tracking issue.

  Special thanks to @bastimeyer, @cthoyt, @edgarrmondragon, and @srittau for helping review and test the types ahead of the release. (#7272)

Improvements

• Digest Auth hashing algorithms have added usedforsecurity=False to clarify security considerations. (#7310)
• Requests added support for Python 3.15 based on beta1. Downstream projects should be able to start testing prior to its release in October. (#7422)
• Requests added support for Python 3.14t. (#7419)

Bugfixes

• Response.history no longer contains a reference to itself, preventing accidental looping when traversing the history list. (#7328)
• Requests no longer performs greedy matching on no_proxy domains. The proxy_bypass implementation has been updated with CPython's fix from bpo-39057. (#7427)
• Requests no longer incorrectly strips duplicate leading slashes in URI paths. This should address user issues with specific presigned URLs. Note the full fix requires urllib3 2.7.0+. (#7315)

2.33.1 (2026-03-30)

Bugfixes

• Fixed test cleanup for CVE-2026-25645 to avoid leaving unnecessary files in the tmp directory. (#7305)
• Fixed Content-Type header parsing for malformed values. (#7309)
• Improved error consistency for malformed header values. (#7308)

2.33.0 (2026-03-25)

Announcements

• 📣 Requests is adding inline types. If you have a typed code base that uses Requests, please take a look at #7271. Give it a try, and report any gaps or feedback you may have in the issue. 📣

Security

• CVE-2026-25645 requests.utils.extract_zipped_paths now extracts contents to a non-deterministic location to prevent malicious file replacement. This does not affect default usage of Requests, only applications calling the utility function directly.

Improvements

• Migrated to a PEP 517 build system using setuptools. (#7012)

Bugfixes

• Fixed an issue where an empty netrc entry could cause malformed authentication to be applied to Requests on Python 3.11+. (#7205)

Deprecations

• Dropped support for Python 3.9 following its end of support. (#7196)

Documentation

• Various typo fixes and doc improvements.

2.32.5 (2025-08-18)

Bugfixes

• The SSLContext caching feature originally introduced in 2.32.0 has created a new class of issues in Requests that have had negative impact across a number of use cases. The Requests team has decided to revert this feature as long term maintenance of it is proving to be unsustainable in its current iteration.

Deprecations

• Added support for Python 3.14.
• Dropped support for Python 3.8 following its end of support.

2.32.4 (2025-06-10)

Security

• CVE-2024-47081 Fixed an issue where a maliciously crafted URL and trusted environment will retrieve credentials for the wrong hostname/machine from a netrc file. (#6965)

Improvements

• Numerous documentation improvements

Deprecations

• Added support for pypy 3.11 for Linux and macOS. (#6926)
• Dropped support for pypy 3.9 following its end of support. (#6926)

2.32.3 (2024-05-29)

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)

2.32.2 (2024-05-21)

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)

2.32.1 (2024-05-20)

Bugfixes

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