Release 2.15.2

Since rapidfuzz v2.x is still widely used, Python 3.12 support is backported to rapidfuzz v2.x.

Added

• add python 3.12 support

Release 3.3.1

Added

• add missing tag for python 3.12 support

Release 3.3.0

Changed

• upgrade to Cython==3.0.2
• implement the remaining missing features from the C++ implementation in the pure Python implementation

Added

• added support for Python 3.12

Release 3.2.0

Changed

• build x86 with sse2/avx2 runtime detection

Release 3.1.2

Changed

• upgrade to Cython==3.0.0

Release 3.1.1

Changed

• upgrade to taskflow==3.6

Fixed

• replace usage of isnan with std::isnan which fixes the build on NetBSD

Release 3.1.0

Changed

• added keyword argument pad to Hamming distance. This controls whether sequences of different
  length should be padded or lead to a ValueError
• improve consistency of exception messages between the C++ and pure Python implementation
• upgrade required Cython version to Cython==3.0.0b3

Fixed

• fix missing GIL restore when an exception is thrown inside process.cdist
• fix incorrect type hints for the process module

Release 3.0.0

Changed

• allow the usage of Hamming for different string lengths. Length differences are handled as
  insertions / deletions

• remove support for boolean preprocessor functions in rapidfuzz.fuzz and rapidfuzz.process.
  The processor argument is now always a callable or None.

• update defaults of the processor argument to be None everywhere. For affected functions this can change results, since strings are no longer preprocessed. To get back the old behaviour pass processor=utils.default_process to these functions. The following functions are affected by this:

  • process.extract, process.extract_iter, process.extractOne
  • fuzz.token_sort_ratio, fuzz.token_set_ratio, fuzz.token_ratio, fuzz.partial_token_sort_ratio, fuzz.partial_token_set_ratio, fuzz.partial_token_ratio, fuzz.WRatio, fuzz.QRatio

• rapidfuzz.process no longer calls scorers with processor=None. For this reason user provided scorers no longer require this argument.

• remove option to pass keyword arguments to scorer via **kwargs in rapidfuzz.process. They can be passed
  via a scorer_kwargs argument now. This ensures this does not break when extending function parameters and
  prevents naming clashes.

• remove rapidfuzz.string_metric module. Replacements for all functions are available in rapidfuzz.distance

Added

• added support for arbitrary hashable sequence in the pure Python fallback implementation of all functions in rapidfuzz.distance
• added support for None and float("nan") in process.cdist as long as the underlying scorer supports it.
  This is the case for all scorers returning normalized results.

Fixed

• fix division by zero in simd implementation of normalized metrics leading to incorrect results

Release 2.15.1

Fixed

• fix incorrect tag dispatching implementation leading to AVX2 instructions in the SSE2 code path

Added

• add wheels for windows arm64

Release 2.15.0

Changed

• allow the usage of finite generators as choices in process.extract
