Change Log

This project attempts to adhere to Semantic Versioning.

Unreleased

0.10.0 - (2020-01-31)

Added

• Sørensen-Dice implementation (thanks @robjtede)

0.9.3 - (2019-12-12)

Fixed

• Fix Jaro and Jaro-Winkler when the arguments have lengths of 1 and are equal. Previously, the functions would erroneously return 0 instead of 1. Thanks to @vvrably for pointing out the issue.

0.9.2 - (2019-05-09)

Changed

• Revert back to the standard library hashmap because it will use hashbrown very soon
• Remove ndarray in favor of using a single vector to represent the 2d grid in Damerau-Levenshtein

0.9.1 - (2019-04-08)

Changed

• Faster Damerau-Levenshtein implementation (thanks @lovasoa)

0.9.0 - (2019-04-06)

Added

• Generic distance functions (thanks @lovasoa)

0.8.0 - (2018-08-19)

Added

• Normalized versions of Levenshtein and Damerau-Levenshtein (thanks @gentoid)

0.7.0 - (2018-01-17)

Changed

• Faster Levenshtein implementation (thanks @wdv4758h)

Removed

• Remove the “against_vec” functions. They are one-liners now, so they don‘t seem to add enough value to justify making the API larger. I didn’t find anybody using them when I skimmed through a GitHub search. If you do use them, you can change the calls to something like:

let distances = strings.iter().map(|a| jaro(target, a)).collect();

0.6.0 - (2016-12-26)

Added

• Add optimal string alignment distance

Fixed

• Fix Damerau-Levenshtein implementation (previous implementation was actually optimal string alignment; see this Damerau-Levenshtein explanation)

0.5.2 - (2016-11-21)

Changed

• Remove Cargo generated documentation in favor of a docs.rs link

0.5.1 - (2016-08-23)

Added

• Add Cargo generated documentation

Fixed

• Fix panic when Jaro or Jaro-Winkler are given strings both with a length of one

0.5.0 - (2016-08-11)

Changed

• Make Hamming faster (thanks @IBUzPE9) when the two strings have the same length but slower when they have different lengths

0.4.1 - (2016-04-18)

Added

• Add Vagrant setup for development
• Add AppVeyor configuration for Windows CI

Fixed

• Fix metrics when given strings with multibyte characters (thanks @WanzenBug)

0.4.0 - (2015-06-10)

Added

• For each metric, add a function that takes a vector of strings and returns a vector of results (thanks @ovarene)

0.3.0 - (2015-04-30)

Changed

• Remove usage of unstable Rust features

0.2.5 - (2015-04-24)

Fixed

0.1.0 - (2015-02-09)

Added
