This is one of the most remarkable Sudoku puzzles I've ever seen - previously I thought that applications of the so-called Phistomefel's theorem could always be side-stepped by other easier techniques. I've double checked using solvers and this is not the case with this puzzle, which makes this the first time I've seen genuine novelty in a Sudoku in as long as I can remember.
I think some of the petty comments and vindictive ratings here are very unfortunate, and certainly not what this puzzle deserves!

I just realised you've uploaded 4 puzzles in the space of three days (which is a bit too many given the current flood of puzzles).
Read here about the situation on the forum (written by Richard):
Maybe wait a few days between uploading each puzzle (so that new puzzles don't get lost). This message isn't to stop you from posting future puzzles, but to just make you aware of the current situation.
