I mentioned it a few days ago, when it was near the end, and now it's officially over: Stockfish won the 100-game superfinal match over LeelaChessZero 54.5-45.5. Happily, both engines are available to everyone for free, so we're the real winners here. (At least we are, relative to the situation if the top engines were only available for a fee. One might wonder whether the arms race that engine use generates really is for the best.)
