Sourced from charset-normalizer's releases.

Version 3.4.3

3.4.3 (2025-08-09)

Changed

• mypy(c) is no longer a required dependency at build time if CHARSET_NORMALIZER_USE_MYPYC isn't set to 1. (#595) (#583)
• automatically lower confidence on small bytes samples that are not Unicode in detect output legacy function. (#391)

Added

• Custom build backend to overcome inability to mark mypy as an optional dependency in the build phase.
• Support for Python 3.14

Fixed

• sdist archive contained useless directories.
• automatically fallback on valid UTF-16 or UTF-32 even if the md says it's noisy. (#633)

Misc

• SBOM are automatically published to the relevant GitHub release to comply with regulatory changes. Each published wheel comes with its SBOM. We choose CycloneDX as the format.
• Prebuilt optimized wheel are no longer distributed by default for CPython 3.7 due to a change in cibuildwheel.
