Changelog

Sourced from similar's changelog.

3.2.1

• Improved real-world diffing performance substantially without changing the produced diffs. On a corpus of real source file revisions, line diffs run about 4x faster with Algorithm::Myers, 5x faster with Algorithm::Histogram, and 2.5x faster with Algorithm::Patience; word diffs run about 2x faster. This comes from a faster line tokenizer, a SipHash-1-3 content hash that consumes whole words (randomly keyed with std), cheaper integer-keyed lookup tables, hashing only the changed middle of Myers line diffs, flat occurrence tables in Histogram, and a gap buffer in the compaction pass that was quadratic on diffs with many ops. Allocation counts and peak memory dropped as well; in particular one sided and heavily unbalanced inputs no longer build index structures proportional to the larger side for Algorithm::Hunt, Algorithm::Histogram, and Algorithm::Patience.
• Fixed Algorithm::Histogram overflowing the stack on inputs with many scattered changes. Pending ranges are now tracked on the heap, so stack usage no longer grows with the number of anchors. #105
• Fixed TextMerge::labels writing carriage returns and newlines verbatim into conflict markers, which let a label add lines to the output that looked like merged content. Line terminators in labels are now replaced with spaces. #101
