Release Notes

jawah/charset_normalizer (charset-normalizer)

v3.5.2

Compare Source

Changed

• Raised the Cython upper bound to <3.4 for native builds. The bound remains <3.3 for
  abi3 builds to preserve compatibility with the Python 3.7 Limited API.

Fixed

• Valid UTF-8 Chinese JSON incorrectly detected as PTCP154 due to excessive noise penalties
  for uncommon CJK characters. (#​796)
• Supported encodings without aliases failing name resolution or being ignored in charset
  declarations. (#​800)

[claude]

LGTM, trivial dependency-lockfile bump.

• Checked the diff: only charset-normalizer 3.5.1 → 3.5.2 pin changed in requirements.txt and requirements-dev.txt, no other lines touched.
• Upstream changelog for 3.5.2 lists a Cython bound tweak and two encoding-detection bugfixes, nothing that affects this repo's usage.

Extended reasoning...

The change touches only requirements.txt and requirements-dev.txt, bumping the charset-normalizer pin from 3.5.1 to 3.5.2 in both files with no other lines modified. This is a Renovate-generated dependency lockfile update with no source code changes and no security-sensitive surface (auth, crypto, permissions) touched. The bump is a patch-level release fixing minor encoding-detection bugs, which is low risk and mechanical in nature, so no human review is needed.
