Rules
Normal sudoku rules apply, and all clues are standard.
Palindromes: gray lines are palindromes, which contain the same sequence of digits in either direction.
Quadruple circles: a digit inside a white circle appears in one of the four cells surrounding that circle (if a digit repeats in a circle, it appears in two of the surrounding cells).
This puzzle originally appeared in Artisanal Sudoku, Volume 234. You've probably already heard about Artisanal Sudoku, but if you haven't, I highly recommend checking it out. It is a weekly newsletter by James Sinclair and features Sudoku puzzles that are approachable and engaging.
Solution code: Row 9
