Another Yin-Yang puzzle with dynamic fog for those who love it :-)
I hope you will enjoy and I would be really grateful for all the comments and ratings.

Normal sudoku rules apply.

Yin-Yang: Shade some cells in the grid so that all shaded cells are orthogonally connected, all unshaded cells are orthogonally connected, and no 2×2 region is entirely shaded or entirely unshaded.

Values: A shaded cell containing digit x has value -x; an unshaded cell containing digit x has value x. In other words, shaded cells have negative values, and unshaded cells have positive values.

Region sum line: Box borders divide a blue line into segments which have the same sum of values. Different lines may have different sums.

Kropki dots: Values in cells joined by a white dot with 8 have difference of 8. Values in cells joined by a black dot are in a 1:2 ratio (i.e., one value will be double the other). Not all dots are necessarily given.
Hint (highlight to see): Black dot can only join two negative or two positive values. 4 and -8 are not in 1:2 ratio.

Killer: Values in a cage sum to the total given.

V: Values in cells joined by a V sum to either 5 or -5. Not all Vs are given.

Dynamic Fog of War: The grid is partially covered in fog. Placing correct digits reveals their own cell and may also lift fog elsewhere in the grid. No guessing is required.
