Play in Sudokupad
Normal sudoku rules apply.
Limitations: Digits may not repeat on any little killer diagonal, thermometer, same colored line or in any cage (rules 1-6 below).
1. Little Killer Diagonals: Clues outside the grid show the sum of the digits along the indicated diagonal.
2. Digits along a thermometer increase from the bulb to the tip.
3. When a box border divides a blue region sum line into segments, the digits along one segment sum to the same value as the adjacent segment. Different lines may have different segment sums.
4. Digits along a purple Renban line form a set of consecutive digits in any order.
5. Adjacent digits along a green German Whisper line have a difference of five or more.
6. Digits in a cage sum to a number that is not given.
The grid is partially covered in fog. Placing correct digits may clear fog somewhere in the grid.
Solution code: Row 9

Edited rule for clarity

I agree with Merovius about the rule statements - I got completely wrong idea when I was reading them.
Otherwise approachable and pleasant puzzle, thank you for setting!

IMO the rule is stated ambiguously and should be clarified.
The way I understand the stated rule, it would be allowed for one digit to appear on two different blue lines, for example - it just must not repeat on any line (singular).
But I assume it is meant that digits may not repeat on any rule class, so if e.g. a digit appears on one blue line, it must not appear on any other blue line.
---I have edited the rule to same colored line. You are correct-all the blue lines are limited to one digit appearance.

Not the most difficult puzzle, but I really enjoyed it. This ruleset (limitations) is really enjoyable and I've loved this series. This one deserves a higher rating imo. A solid 94% or better! thanks for sharing.

Very nice limitation constraint, although I not sure that my cages followed the rule of summing to a number ;)
