• Support for alternative language frequency set in charset_normalizer.assets.FREQUENCIES
• Add parameter language_threshold in from_bytes, from_path and from_fp to adjust the minimum expected coherence ratio
• normalizer --version now specify if the current version provides extra speedup (meaning mypyc compilation whl)

Changed

• Build with static metadata (not pyproject.toml yet)
• Make language detection stricter
• Optional: Module md.py can be compiled using Mypyc to provide an extra speedup up to 4x faster than v2.1

Fixed

• CLI with opt --normalize fail when using full path for files
• TooManyAccentuatedPlugin induce false positive on the mess detection when too few alpha characters have been fed to it
• Sphinx warnings when generating the documentation

Removed

• Coherence detector no longer returns 'Simple English' instead returns 'English'
• Coherence detector no longer returns 'Classical Chinese' instead returns 'Chinese'
• Breaking: Method first() and best() from CharsetMatch
• UTF-7 will no longer appear as "detected" without a recognized SIG/mark (is unreliable/conflicts with ASCII)
