Updates requests from 2.34.0 to 2.34.2

Release notes

Sourced from requests's releases.

v2.34.2

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)

Full Changelog: https://github.com/psf/requests/blob/main/HISTORY.md#2342-2026-05-14

v2.34.1

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)

New Contributors

• @​k223kim made their first contribution in psf/requests#7433
