RapidFuzz 1.1.0

CRAN release: 2026-04-07

Major Changes

• Updated the bundled rapidfuzz-cpp C++ library from v3.0.x to v3.3.3, bringing performance improvements and bug fixes from upstream:
  • Fixed WRatio for a length ratio of exactly 8.0.
  • Added C++11 and C++14 compatibility in the upstream library.
  • Improved calculation of minimum score inside partial_ratio to skip more alignments.
  • Fixed incorrect score calculation for SIMD implementations of Levenshtein and OSA on 32-bit systems.
  • Banded implementation of LCS/Indel for faster runtime with score_cutoff.

New Features

• Added three new fuzzy matching functions from the upstream library:
  • fuzz_partial_token_sort_ratio(): combines token sorting with partial ratio matching.
  • fuzz_partial_token_set_ratio(): combines token set comparison with partial ratio matching.
  • fuzz_partial_token_ratio(): returns the maximum of partial_token_set_ratio and partial_token_sort_ratio.
• extract_matches() now supports additional scorers: "TokenSortRatio", "TokenSetRatio", "TokenRatio", "QRatio", "PartialTokenSortRatio", "PartialTokenSetRatio", and "PartialTokenRatio", in addition to the existing "WRatio", "Ratio", and "PartialRatio".

Improvements

• Added cli package integration for formatted startup messages.
• Updated package documentation and website.

Authors

• Added Marcos Wasilew and Carlos Amorim as package authors.
