• New rescue — watch a short ad after a loss to get the board back, twice per game • Losing no longer leaves the board silent: you get your result and a way to start again • The board is repainted in warm ivory, with the cells filling the frame edge to edge • A new app icon, and the same sprout mark beside the title • Time Attack now gives you longer as the board gets harder (5 · 7 · 10 · 12 minutes) • Haptics can be switched off in settings, and the language can follow your device • The growth stages are re-spaced, so the sprout grows from your very first board • The victory screen, the header and the keypad have been tidied up • Settings gains a link to the games homepage and shows the app version • Fixed: undo no longer hands back a mistake you have already used
