Play this puzzle online at the Daily Sudoku site

Looks like this one depends on two 13-7 XY wings- pivots r2c5 and r6c6.
Neither do it in one, but they can be used in either order. I'm not sure I've
seen one like this before. Worth the wait.

I played the 13-7 pivoted in r6c6 first. Then either the 13-7 pivoted in r2c5 or the 16-7 in r5c9 finishes it.
