What's New in StonePath
1.3.0
October 7, 2026
• New: games on a 13x13 board against the same ten opponents. Choose the board size on the Game screen. • Top moves, the territory map and game review work on 13x13 too. • Opponents now play close to their stated ranks: each one's strength was measured in games against a Go program whose rating is known from games with human players. On 9x9, most were previously stronger than their labels indicated.
