changelog

build 47, under the hood. reliability and security hardening across accounts and challenges, plus sharper tooling for authoring the daily challenges.

deep think, leveled up. a real xp + level results screen, xp weighted by puzzle difficulty, and a fresh set of deep-think badges to chase.

friends, done properly. head-to-head leaderboards with stat and badge comparison, invites you approve before anyone can compete with you, and a tap-through coding vs quant breakdown.

smoother every day. an even mix of puzzle types, forgiving number grading, per-track reminders, a self-updating streak widget, the 10pm streak live activity, and full dark mode.

fixes & polish. cleaner challenge diagrams and code generics, no more onboarding bounce after your first session, and offline level-up celebrations that play once you sync.
