What's New in StonePath
1.4.0
November 2, 2026
• New in the Tactics tab: joseki for the 13×13 board — ten corner sequences from the 4-4, 3-4, and 3-3 points. • Every move has been checked by KataGo on 13×13. If a move from a 19×19 line loses 0.8 points or more on 13×13, it’s marked with an X, with the 13×13 move shown next to it. • When the bot passes, “Bot: pass” is now shown above the board, and a pass no longer plays the capture sound.
