charset_normalizer 3.4.5

3.4.5 (2026-03-06)

Changed

• Update setuptools constraint to setuptools>=68,<=82.
• Raised upper bound of mypyc for the optional pre-built extension to v1.19.1

Fixed

• Add explicit link to lib math in our optimized build. (#692)
• Logger level not restored correctly for empty byte sequences. (#701)
• TypeError when passing bytearray to from_bytes. (#703)

Misc

• Applied safe micro-optimizations in both our noise detector and language detector.
• Rewrote the query_yes_no function (inside CLI) to avoid using ambiguous licensed code.
• Added cd.py submodule into mypyc optional compilation to reduce further the performance impact.

[!WARNING]
mypyc changed the usual binary output for the optimized wheel. Beware, especially if using PyInstaller or alike. See https://github.com/jawah/charset_normalizer/issues/714
