What we've shipped.

Every feature, fix, and ops-change to Sheet2Classroom. In reverse chronological order.

1. Apr 23, 2026Feature

   /appv2 promoted to /app — single canonical app tree

   Dashboard, browse-all-assignments, snapshots, per-student restore, grade histogram, and the assignment combobox are no longer behind a /appv2 prefix. The old frozen /app tree is gone; /appv2 was renamed to /app in one move, all internal links were rewritten, and the v1/v2 variant split was retired from the shared nav.

   • Single /app/* route tree — no more v1/v2 split
   • AppNav dropped its variant prop; Dashboard + History links are always shown
   • Internal hrefs and imports rewritten in one sed pass
   • robots.ts deduped private-route list
2. Apr 22, 2026Feature

   Dashboard + assignment combobox

   A multi-course dashboard aggregating pushes/snapshots/expiring backups across everything you teach. Assignment name input now shows a dropdown of existing coursework so you can update instead of creating.

   • New /app/dashboard with hero stats, activity feed, per-course grouping, and expiring-backup warnings
   • Type-ahead dropdown on assignment title — pick existing coursework to auto-switch to Update mode
   • Dashboard icon in the app nav
   • Public changelog (this page)
3. Apr 22, 2026Feature

   Browse all assignments, snapshots, per-student restore, grade histogram

   Four feature drops shipped in one wave.

   • Browse every assignment in a course at /app/course/[id]/assignments
   • One-click "Save snapshot" — backs up current grades without pushing
   • Per-student restore: checkboxes on every row in the restore preview
   • Grade distribution histogram on the push preview — bars over max tint red
4. Apr 22, 2026Fix

   Sign-out crash + button feedback

   Sign out was crashing with "This page couldn't load" because of an inline server action binding issue in Next 16 + Turbopack. Moved to a shared actions file + added pending state.

   • Dedicated src/app/actions.ts with signInWithGoogle + signOutAndGoHome
   • Loading spinner + "Signing out…" text + disabled state via useFormStatus
   • Cursor changes to wait during sign-out
5. Apr 22, 2026Feature

   Restore-with-diff + readability pass

   No more "OK/Cancel for show" on restore. Every destructive action now previews the exact change before committing.

   • Restore now fetches current grades and shows a Now → Will-revert-to table
   • Loud warning when student-visible grades will change
   • Assignment mode card redesigned: bigger, clearer, with "SELECTED" pill
   • Stat cards use tabular-nums + 3x larger values
   • Saved-mapping chip reads as a real chip with a proper Reset button
6. Apr 22, 2026Feature

   Update-existing-assignment with mandatory backup

   Detect when an assignment title already exists. Offer Create New or Update — never silently overwrite.

   • Full diff table: current grade → new grade per student
   • Red warning for grades already visible to students
   • Every backup restorable for 30 days via Upstash Redis
   • Push history page with filter + restore per entry
7. Apr 22, 2026Feature

   Name-match + interactive resolver

   Personal-Gmail students whose email is hidden by Google can now be matched by name from the class roster.

   • New classroom.rosters.readonly scope fetches the roster directly
   • Fuzzy name matching: exact + token-subset (middle names OK)
   • Duplicate-name detection → shows in unmatched with candidate picker
   • Inline dropdown on every unmatched row to pick the right student manually
8. Apr 21, 2026Feature

   Full visual overhaul

   Linear/Moneyflow-inspired layout. Emerald brand. Plus Jakarta Sans. Animated hero grid. Scroll-triggered section reveals.

   • Hero with animated 4-card grid — Drafts first, Smart matching, Last push, Undo any push
   • Framer Motion scroll animations with staggered children
   • Favicon + OG image regenerated
   • Dark mode removed — light theme only per teacher feedback
9. Apr 21, 2026Feature

   Wizard MVP

   Four-screen flow shipped: pick course, paste sheet, map columns, preview and push.

   • Google Classroom + Sheets integration
   • Grade format parsing: numbers, "85/100", "85%", "85 pts"
   • Auto-guess columns from header names
   • Draft-first grading by default
   • Rollup pre-push check: no assignment created if zero matches
