Release Notes

chardet/chardet (chardet)

v7.0.1

Compare Source

Fixes

  • Fixed false UTF-7 detection of SHA-1 git hashes (#​324, fixing #​323) — requirements files with VCS pins (e.g., +4bafdea3...) were misdetected as UTF-7, breaking tools like tox
  • Fixed _SINGLE_LANG_MAP missing aliases for single-language encoding lookup (e.g., big5 → big5hkscs)
  • Fixed PyPy TypeError in UTF-7 codec handling

Improvements

  • Retrained bigram models — 24 previously failing test cases now pass
  • Updated language equivalences for mutual intelligibility (Slovak/Czech, East Slavic + Bulgarian, Malay/Indonesian, Scandinavian languages)

New Contributors

  • @​rembish made their first contribution — both reporting the UTF-7 false detection issue and submitting the fix! (#​323, #​324)

v7.0.0

Compare Source

Ground-up, MIT-licensed rewrite of chardet. Same package name, same public API — drop-in replacement for chardet 5.x/6.x. Just way faster and more accurate!

Highlights:

  • MIT license (previous versions were LGPL)
  • 96.8% accuracy on 2,179 test files (+2.3pp vs chardet 6.0.0, +7.7pp vs charset-normalizer)
  • 41x faster than chardet 6.0.0 with mypyc (28x pure Python), 7.5x faster than charset-normalizer
  • Language detection for every result (90.5% accuracy across 49 languages)
  • 99 encodings across six eras (MODERN_WEB, LEGACY_ISO, LEGACY_MAC, LEGACY_REGIONAL, DOS, MAINFRAME)
  • 12-stage detection pipeline — BOM, UTF-16/32 patterns, escape sequences, binary detection, markup charset, ASCII, UTF-8 validation, byte validity, CJK gating, structural probing, statistical scoring, post-processing
  • Bigram frequency models trained on CulturaX multilingual corpus data for all supported language/encoding pairs
  • Optional mypyc compilation — 1.49x additional speedup on CPython
  • Thread-safe detect() and detect_all() with no measurable overhead; scales on free-threaded Python 3.13t+
  • Negligible import memory (96 B)
  • Zero runtime dependencies

Breaking changes vs 6.0.0:

  • detect() and detect_all() now default to encoding_era=EncodingEra.ALL (6.0.0 defaulted to MODERN_WEB)
  • Internal architecture is completely different (probers replaced by pipeline stages). Only the public API is preserved.
  • LanguageFilter is accepted but ignored (deprecation warning emitted)
  • chunk_size is accepted but ignored (deprecation warning emitted)
