Change Log

[0.6.4] - 2024-09-24

Improved

• Fix boxed math warning. [thx @tonsky]
• Update deps

[0.6.3] - 2023-03-14

Improved

• Simplify equality test for A* algorithm, increasing diff speed up to 60% for some data sets.

[0.6.2] - 2022-08-25

Fixed

• A couple of typos in code and documentation.

[0.6.1] - 2022-08-24

Changed

• Breaking Change :str-diff? option for diff to :str-diff, whose value could be :none (default, no diff inside string), :line (diff by line), :word (diff by word) or :character (diff by character, original string diff, very expensive).

Added

• :vec-timeout option for diff, to specify a timeout in milliseconds (default 1000), for it is sometimes too expensive to diff vectors. It is O(n^2), after all. When timed-out, a replacement will be used.
• :str-change-limit option for diff, a less than 1.0 and greater than 0.0 double, representing percentage (default 0.2). Only diff string when less than given percentage is changed, otherwise replace the string. Because string diff is expensive, it may be cheaper to replace the whole string.

Improved

• Speed up string diff by coercing into vector first.
• Bump Clojure version

[0.5.8] - 2021-12-30
