I felt like doing Global Entropy again - hope you all like it!

- Normal sudoku rules apply.

- Global Entropy - every 2 by 2 box of cells must contain a low digit (1, 2, or 3), a medium digit (4, 5, or 6), and a high digit (7, 8, or 9).

- Ratio Kropki - digits separated by a black Kropki dot are in a 2:1 ratio. No negative constraint.

- XV sums - digits separated by X sum to 10; digits separated by V sum to 5. No negative constraint.

- German Whispers - neighboring digits on a green German Whisper line differ by at least 5.

- Dutch Whispers - neighboring digits on an orange Dutch Whisper line differ by at least 4.

Accessibility note - the only GW is the square connecting boxes 1 and 5; the other boxes are Dutch.
