What's new in 1.6: • A fresh look — a warmer, sharper design across Home, results, progress, recipes and community, with your latest bake front and centre. • Getting started guide — five short chapters that take you from a jar of flour and water to your first loaf, with steps you can tick off and a quick quiz for each. • Fairer crumb scores — a wider scoring range, so a great loaf can earn a 9. • Bake streaks and celebrations — keep a weekly streak and hit milestones. • Progress page — best, average, loaf count and a score trend at a glance. • Small polish and haptics throughout.
