Another puzzle for Scojo's prompt with row/column indexers and liars this time :-)
My difficulty estimation is 3.5*
I hope you will enjoy and I would be really grateful for all the comments and ratings.

Normal sudoku rules apply.

Row & Column Indexers: Digits placed in cells with double arrows pointing left-right and up-down indicate both the position of the corresponding column number in that row and the position of the corresponding row number in that column. Those are always truth-tellers.

Liars: For each of listed below constraint types (excluding row/column indexers), exactly half of clues is not correct (e.g., exactly 2 of 4 quadruples are missing at least one of the specified digits from its surrounding cells).

Diagonal: Digits along the marked blue diagonals must not repeat.

Arrow: Digits along an arrow sum to the number in the attached circle.

Thermometer: Digits along a gray thermometer increase from bulb to tip.

Quadruples: Digits in a circle must appear within the four surrounding cells.

White kropki dots: Digits in cells joined by a white dot are consecutive.

Black kropki dots: Digits in cells joined by a black dot are in a 1:2 ratio (i.e., one digit will be double the other).

X: Digits in cells joined by an X sum to 10.

V: Digits in cells joined by a V sum to 5.
