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.
