Version 2.0.7

We arrived in a pretty stable state.

Changes:

• Addition: 🍱 Add support for Kazakh (Cyrillic) language detection #109
• Improvement: ❇️ Further improve inferring the language from a given code page (single-byte) #112
• Removed: 🔥 Remove redundant logging entry about detected language(s) #115
• Miscellaneous: 🔧 Trying to leverage PEP263 when PEP3120 is not supported #116
  • While I do not think that this (116) will actually fix something, it will rather raise a SyntaxError (Not about ASCII decoding error) for those trying to install this package using a non-supported Python version
• Improvement: ⚡ Refactoring for potential performance improvements in loops #113 @adbar
• Improvement: ✨ Various detection improvement (MD+CD) #117
• Bugfix: 🐛 Fix a minor inconsistency between Python 3.5 and other versions regarding language detection #117 #102

This version pushes forward the detection-coverage to 98%! https://github.com/Ousret/charset_normalizer/runs/3863881150
The great filter (cannot be better than) shall be 99% in conjunction with the current dataset. In future releases.

• Bugfix: 🐛 Unforeseen regression with the loss of the backward-compatibility with some older minor of Python 3.5.x #100
• Bugfix: 🐛 Fix CLI crash when using --minimal output in certain cases #103
• Improvement: ✨ Minor improvement to the detection efficiency (less than 1%) #106 #101

Version 2.0.5

Changes:

Internal: 🎨 The project now comply with: flake8, mypy, isort and black to ensure a better overall quality #81
Internal: 🎨 The MANIFEST.in was not exhaustive #78
Improvement: ✨ The BC-support with v1.x was improved, the old staticmethods are restored #82
Remove: 🔥 The project no longer raise warning on tiny content given for detection, will be simply logged as warning instead #92
Improvement: ✨ The Unicode detection is slightly improved, see #93
Bugfix: 🐛 In some rare case, the chunks extractor could cut in the middle of a multi-byte character and could mislead the mess detection #95
Bugfix: 🐛 Some rare 'space' characters could trip up the UnprintablePlugin/Mess detection #96
Improvement: 🎨 Add syntax sugar __bool__ for results CharsetMatches list-container see #91

This release push further the detection coverage to 97 % !
