I believe this may be my most difficult to date. I finally achieved a break-in that isn't completely telegraphed, but is still certainly findable. You'll find this puzzle to be a 2-parter I think, and I hope all of you enjoy it.
Normal Sudoku Rules Apply
All 4s and all 8s in the puzzle must adhere to the antiknight rule, i.e. no 4 can be a knight's move (in chess) away from any other 4. Likewise, no 8 can be a knight's move away from any other 8. All other digits do not face this restriction.
Green lines are German Whispers lines. Adjacent digits along a German Whispers line must differ in value by at least 5.
Gray lines are palindromes, and must be read the same forwards and backwards.
Digits along the marked diagonal cannot repeat.
Cells joined by white dots are consecutive in value. Not all dots are given.
Cells joined by Vs sum to 5. Not all Vs are given.
The cell with a gray circle contains an odd digit.

I'm happy to have finally solved this puzzle, even though it is a month after it was published. But I'm not thrilled with my solution. I never found "the break in". I just kept going back to the puzzle and trying options - searching for what I must be missing. Thanks, Tingo, for providing the challenge. I enjoy your puzzles.
- Congratulations on solving it! Thanks for playing and thanks for the kind words. Cheers - Tingo

Wow, that was tough (for me). I kept incorrectly applying the knight's move constraint to digits other than 4 and 8, which did not work out well ;-)
Thanks for setting.
- When I tested this puzzle to see if it was humanable, I originally thought it wasn't because I kept doing the same thing. Once I wrapped my mind around the concept of only 2 digits, it got better. Thanks for playing and I'm glad you made it! Cheers! - Tingo
