Release Notes

v5.2.0

Commits

• #411 Big performance improvement. Previously an O(n) array-copying operation inside the innermost loop of jsdiff's base diffing code increased the overall worst-case time complexity of computing a diff from O(n²) to O(n³). This is now fixed, bringing the worst-case time complexity down to what it theoretically should be for a Myers diff implementation.
• #448 Performance improvement. Diagonals whose furthest-reaching D-path would go off the edge of the edit graph are now skipped, rather than being pointlessly considered as called for by the original Myers diff algorithm. This dramatically speeds up computing diffs where the new text just appends or truncates content at the end of the old text.
• #351 Importing from the lib folder - e.g. require("diff/lib/diff/word.js") - will work again now. This had been broken for users on the latest version of Node since Node 17.5.0, which changed how Node interprets the exports property in jsdiff's package.json file.
• #344 diffLines, createTwoFilesPatch, and other patch-creation methods now take an optional stripTrailingCr: true option which causes Windows-style \r\n line endings to be replaced with Unix-style \n line endings before calculating the diff, just like GNU diff's --strip-trailing-cr flag.
• #451 Added diff.formatPatch.
• #450 Added diff.reversePatch.
• #478 Added timeout option.
