Tokenizer 1.29.0

Changes

• [Python] Drop support for Python 3.5

New features

• [Python] Build wheels for Python 3.10
• [Python] Add tokenization method Tokenizer.tokenize_batch

Tokenizer 1.28.1

Fixes and improvements

• Fix detokenization when a token includes a fullwidth percent sign (％) that is not used as an escape sequence (version 1.27.0 contained a partial fix for this bug)

Tokenizer 1.28.0

Changes

• [C++] Remove the SpaceTokenizer class that is not meant to be public and can be confused with the "space" tokenization mode

New features

• Build Python wheels for Windows
• Add option tokens_delimiter to configure how tokens are delimited in tokenized files (default is a space)
• Expose option with_separators in Python and CLI to include whitespace characters in the tokenized output
• [Python] Add package version information in pyonmttok.__version__

Fixes and improvements

• Fix detokenization when option with_separators is enabled

Tokenizer 1.27.0

Changes

• Linux Python wheels are now compiled with manylinux2010 and require pip >= 19.0 for installation
• macOS Python wheels now require macOS >= 10.14

Fixes and improvements

• Fix casing resolution when some letters do not have case information
• Fix detokenization when a token includes a fullwidth percent sign (％) that is not used as an escape sequence
• Improve error message when setting invalid segment_alphabet or lang options
• Update SentencePiece to 0.1.96
• [Python] Improve declaration of functions and classes for better type hints and checks
• [Python] Update ICU to 69.1

Tokenizer 1.26.4

Fixes and improvements

• Fix regression introduced in last version for preserved tokens that are not segmented by BPE

Tokenizer 1.26.3

Fixes and improvements

• Fix another divergence with the SentencePiece output when there is only one subword and the spacer is detached

Tokenizer 1.26.2

Fixes and improvements

• Fix a divergence with the SentencePiece output when the spacer is detached from the word

Tokenizer 1.26.1

Fixes and improvements

• Fix application of the BPE vocabulary when using preserve_segmented_tokens and a subword appears without joiner in the vocabulary
• Fix compilation with ICU versions older than 60

Tokenizer 1.26.0

New features

• Add lang tokenization option to apply language-specific case mappings

Fixes and improvements

• Use ICU to convert strings to Unicode values instead of a custom implementation

Tokenizer 1.25.0

New features

• Add training flag in tokenization methods to disable subword regularization during inference
• [Python] Implement __len__ method in the Token class

Fixes and improvements

• Raise an error when enabling case_markup with incompatible tokenization modes "space" and "none"
• [Python] Improve parallelization when Tokenizer.tokenize is called from multiple Python threads (the Python GIL is now released)
• [Python] Cleanup some manual Python <-> C++ types conversion
