Skåne: A Sudoku with an Homage to Skåne, Sweden

Today's Puzzle:

I don't know about you, but it's been a tough set of puzzles this weekend. What we all need I think is a nice smooth solve to wrap up the weekend, and this puzzle delivers in spader.

Rules:

Normal Sudoku: Place the digits 1 to 9 in every row, column, and 3x3 box.

Dutch Whispers: Adjacent digits on an orange line must have a difference of at least 4.

Sandwich sums: Digits outside the grid give the sum of the digits between the 1 and the 9 in that column.

The digit on the grey circle is odd. (Also marks Malmö, which is the largest city in Skåne)

Digits separated by a white dot must be consecutive.
