Huge thank you to gUBBLOR and Jobo for the two puzzles. I've found gUBBLOR's puzzle highly approachable, whilst Jobo's quite difficult. Your mileage may vary!

Rules 1:

Normal Sudoku rules apply. Place the digits 1 through 9 in each empty cell. Digits must not repeat within the same row, column, or box.

German Whispers: Adjacent digits along each German Whisper line must have a difference of at least 5. Digits may repeat on the line.

Thermometers: Digits along each thermometer must increase starting from the bulb end. Digits may repeat on thermometers.

Arrows: The digits along each arrow must sum to the digit in the circled cell. Digits may repeat on arrows.

Kropki dots: A black dot between cells indicates cell values with a 2:1 ratio. A white dot between cells indicates cells with consecutive values. Not all dots are shown.

XV: Adjacent cells connected with an X must sum to 10. Adjacent cells connected with a V must sum to 5. Not all X's or V's are shown.

For clarity, R5C6 is the bulb of both a bidirectional arrow and a bidirectional thermo.

Rules 2:

Normal sudoku rules apply.

Cells separated by a king's move cannot contain the same digit. Digit separated by a white dot must differ by the indicated amount.

Every line is a different constraint out of the following.

Thermometer: Digits along the thermometer must increase from the bulb to the tip, which can be on either end and are to be deduced. Renban: The renban contains a non-repeating set of consecutive digits in any order. Parity line: Digits along the parity line all have the same parity (odd or even). German whisper: Adjacent digits along the German whisper must differ by at least 5. Region sum line: Box borders divide the region sum line into segments with the same sum.

The line in column 9, styled as an exclamation mark, counts as a single line of length 5.
