Normal Sudoku rules apply.
For accessibility, lines have been marked with an abbreviation to distinguish them as an alternative to the line's colour.
Cells connected by a pink RN Renban line form a set of consecutive digits, in any order, without repeats.
Adjacent digits along a green GW German Whisper line must differ by at least 5.
Adjacent digits along an orange DW Dutch Whisper line must differ by at least 4.
Box borders divide the blue RS Region Sum line into segments with the same sum.
Digits on the grey PD Palindrome line read the same forwards and backwards.
Cells joined by an X sum to 10. Cells joined by a V sum to 5.
Cells joined by a white dot are consecutive. Cells joined by a black dot, one digit is double the other.
Not all Xs, Vs or dots are given.

For some reason, my first 2 tries gave no complete solve. That's because I kept treating the renban as a region sum line too. Maybe there is many puzzle with that kind of rules, I got stuck into thinking that. Anyway, great puzzle

Fun puzzle! Flows nicely and unravels very quickly once the first few digits are placed. :)

I do so enjoy these mixed variant puzzles. There are so many clues and so many places from which to start! It's like being a kid on Christmas morning deciding which present to open first :) Thanks for a but of nostalgia
