- ⌥→ / ⌥← now copy the difference and STAY on it, as WinMerge does by default — the automatic advance moved to the new Copy and Advance commands on ⌃⌥→ / ⌃⌥← (WinMerge's own shortcuts). Copy All lives only in the Merge menu, also like the original.
Install: open the dmg and drag to Applications (replace the previous version).
