Halfway There, by James Sinclair

Normal sudoku rules apply.
Exactly one cell in each row, column, and box is a "halver", and halver cells contain a complete set of the digits 1-9. The value of a halver cell is equal to its digit divided by two. (All other cells have a value equal to their digit.)
Cages: the sum of the values inside each cage is equal to the small number in the top left corner, and digits cannot repeat within a cage (but values can).
Arrows: the sum of the values along an arrow is equal to the value in the connected circle.
Thermometers: values on thermometers strictly increase from the bulb.
Values in cells separated by a V sum to 5.
Values in cells separated by an X sum to 10.
