I'm changing the rules to:
Place a number into each cell so that each region contains the numbers from 1 to N with no repeats, where N is the number of cells in all regions. Numbers of the same value may not touch one another orthogonally. Each row and column contains each number from 1 to N the same number of times.

This will be there in the new IB that I'll post in a while, and in the competition areas.

I hope this answers all questions.

Edit: Feel free to ask if its still unclear.

The new IB is published.
Changes:
- Points distribution added
- Patchwork rules changed

Password protected Puzzle booklet can be downloaded.
Please note the announcement about the grid-size of Turning Fences 3.

Sorry for the very late action but this is done now.

(to clarify for others, it wasn't an additional solution to the puzzle, it was just the correct solution sent via email.)
