- Try to reduce memory allocations - Add possibility to disable diff highlight (can improve performance for large diffs) - Tweaking with cost for prettier (cleaner) diffs - Do not calculate diff when the number of removed lines in a block is not equal to the number of added lines (this usually resulted in ugly diffs)
