It means the white pawn promotes to a Rook upon reaching the 8th rank. Promotion to a Queen, Bishop or kNight is also possible.
Recently, I've been using stockfish to analyse games. Here Stockfish outputs the position:

Does anybody understand what the " d7c8r" means? By that I mean why is there is a "r" behind the notation?
Thanks in advance
