Has a Sudoku with 16 clues finally been discovered? How good are you at Sudoku?

The “Sudoku” below has 16 clues and two solutions. However the two solutions appear to only swap around the 8s and 9s. Since there are no 8s or 9s in the original puzzle does this mean the solution is unique?
It is believed that there is no Sudoku with 16 clues i.e. with a unique solution. It was mathematically proven in 2012 by Gary McGuire and his team that 17 is the minimum number of clues possible for a valid Sudoku puzzle to have a unique solution; puzzles with 16 or fewer clues cannot have only one solution.

Poll: Should complete designs be shared with the public, or should the community help shape the designs from the start?
The Post recently shared an opinion piece on the Harbour Crossing and why a more democratic approach might be needed 🚗🚲👟
While most decisions sit within the political arena, many organisations—like NZTA—manage long-term projects that go beyond party lines. Politics can sometimes disrupt progress, and the next Harbour Crossing is a big decision that will affect all Aucklanders.
We’d love your thoughts: Should near-complete, shovel-ready designs be shared with the public, or should the community have a hand in shaping the designs from the start?
