Release 2.0.0

Added

• added C-Api which can be used to extend RapidFuzz from different Python modules using any
  programming language which allows the usage of C-Apis (C/C++/Rust)
• added new scorers in rapidfuzz.distance.*
  • port existing distances to this new api
  • add Indel distance along with the corresponding editops function

Changed

• when the result of string_metric.levenshtein or string_metric.hamming is below max
  they do now return max + 1 instead of -1
• Build system moved from setuptools to scikit-build
• Stop including all modules in __init__.py, since they significantly slowed down import time

Removed

• remove the rapidfuzz.levenshtein module which was deprecated in v1.0.0 and scheduled for removal in v2.0.0
• dropped support for Python2.7 and Python3.5

Deprecated

• deprecate support to specify processor in form of a boolean (will be removed in v3.0.0)
  • new functions will not get support for this in the first place
• deprecate rapidfuzz.string_metric (will be removed in v3.0.0). Similar scorers are available
  in rapidfuzz.distance.*

Fixed

• process.cdist did raise an exception when used with a pure python scorer

Performance

• improve performance and memory usage of rapidfuzz.string_metric.levenshtein_editops
  • memory usage is reduced by 33%
  • performance is improved by around 10%-20%
• significantly improve performance of rapidfuzz.string_metric.levenshtein for max <= 31
  using a banded implementation

Release 1.9.1

Fixed

• fix bug in new editops implementation, causing it to SegFault on some inputs (see qurator-spk/dinglehopper#64)

Release 1.9.0

Fixed

• Fix some issues in the type annotations (see #163)

Performance

• improve performance and memory usage of rapidfuzz.string_metric.levenshtein_editops
  • memory usage is reduced by 10x
  • performance is improved from O(N * M) to O([N / 64] * M)

Release 1.8.3

Added

• Added missing wheels for Python3.6 on MacOs and Windows (see #159)

Release 1.8.2

Added

• Add wheels for Python 3.10 on MacOs

Release 1.8.1

Fixed

• Fix incorrect editops results (See #148)

Release 1.8.0

Changed

• Add Wheels for Python3.10 on all platforms except MacOs (see #141)
• Improve performance of string_metric.jaro_similarity and string_metric.jaro_winkler_similarity for strings with a length <= 64

Release 1.7.1

Fixed

• fixed incorrect results of fuzz.partial_ratio for long needles (see #138)

Release 1.7.0

Changed

• Added typing for process.cdist
• Added multithreading support to cdist using the argument process.cdist
• Add dtype argument to process.cdist to set the dtype of the result numpy array (see #132)
• Use a better hash collision strategy in the internal hashmap, which improves the worst case performance

Release 1.6.2

Changed

• improved performance of fuzz.ratio
• only import process.cdist when numpy is available
