Patch notes

Prelaunch 1 - June 2026

First entry on the prelaunch line. The alpha series ran on 0.8.x; 0.9.0 opened the prelaunch track with the Logic First curriculum surfaced on the main Learn tab and end-to-end in-app billing live for testers. 0.9.1 follows it up with chapter-level Insights for Pro users and an across-the-board option-order shuffle.

🚀 New

• Logic First (v1.0.1) on the Learn tab. New banner card at the top of Learn routes to a chapter map showing the 7 chapters + 34 lessons built on the logic-first teaching model. Ch.1 lessons show inline “+ Practice” rows (4 variants each) and the chapter ends with a “Through the Tunnel” capstone scenario. Legacy modules stay intact below the banner - existing testers don’t lose progression.
• In-app billing is live end-to-end. Pro upgrade flow completes a real Google Play purchase via RevenueCat; Pro perks (faster ember refill, free hints in Practice, “patient practice” leniency on Practice variants) light up immediately. Monthly, yearly, and lifetime upgrades all round-trip validated on the internal track. Sale-tier offerings (minor_sale, major_sale, mega_sale) are wired and will surface when an event tier is active.
• Logic First chapter rows on the Insights tab (Pro). Pro users who follow the prelaunch banner now see their progress reflected in Insights: per-chapter accuracy %, completion fraction (“X of Y lessons complete”), capstone status, and a crystal-accented border that visually distinguishes the new section from the legacy module rows below it.
• Option order shuffled in every multiple-choice surface. The authored “correct answer at position 1” bias no longer leaks to the learner. Applies to the main lesson interaction, mini-checks, practice variants, and capstone stages. Shuffle is keyed on the surface’s stable id, so retries within a single attempt keep the same layout - no confusing mid-attempt reshuffles.

🔧 Tuning

• Feedback channels split into Discord + Email. Settings → About used to surface a single mailto row. Now: “Join the Discord” (chat
  • bug reports + feature requests via the server’s triage bot) and “Email support” as separate rows. The Discord tap tries the discord://invite/ deep link first so installed users land in-app instead of in the browser.

🐛 Fixed + polished

• Android typing bugs in the Guided Example block on logic-first lessons.
• Google sign-in OAuth confusion (test track SHA-1 + Web Client ID) resolved.

📝 Notes

• “Prelaunch” status is intentional - the curriculum is the first six chapters of a logic-first re-author, with Ch.1 fully populated as the pilot for practice + capstones. Chapters 2-7 will get their practice + capstone passes on the same update cadence.
• Sale-tier offerings stay invisible until an event tier is active. Today there’s no event running, so testers see the default monthly/yearly/lifetime offering.
