Normal sudoku rules apply. The lines in the puzzle are both German whisper lines and Nabner lines. Each line obeys both rules. IE: Adjacent digits on a whispers / Nabner line must have a difference of five or greater. And -- if a digit appears on a whispers / Nabner line, then the digits consecutive with it must not appear on that line. Also, digits may not repeat on one of these lines. Digits in a cage must sum to the little number in the upper left, and may not repeat in the cage. I think this puzzle is 2 stars out of 5 for difficulty for many solvers, if you read or stumble upon the hint. As always, comments welcome. Thanks!
Hint (highlight to read):
You will save yourself lots of trouble if you ask yourself before you begin, What digits can begin a whisper Nabner line of length 4.

Lots of fun doing this puzzle - well crafted.
PS anyone can enter the solution with as many spaces as you want, no need to state this.
** Thanks for the solve. Re: the spaces thing, good to know, but I may not change my posts -- you know what they say about teaching old dogs new tricks... ;-)

Glad to see you back! I was starting to lose hope. Always enjoyed your puzzles. I was able to finish the two 2 stars puzzles, but I failed twice at the one star hahaha
Thanks and hope to see you again soon.
** Never lose hope! My back catalog will live on, long after my body returns to dust. ;-)

Welcome back, delighted to enjoy your puzzles again.
This is one of the constrains where a prior reflection on its implications simplifies the difficulty of the challenge.
