 # Changelog
 
+## v0.40.0 — 2026-09-21 13:06
+- **Top-bar version link (ISS-080).** The header's version tag (`components/Map.tsx`) is now an anchor to the repo's `CHANGELOG.md` on Gitea (`app-version` testid, opens in a new tab); one small CSS rule keeps it subtle against the dark header. E2E: `e2e/map.spec.ts` pins the exact href
+- **On-board ICAO tags (ISS-081).** The on-board package row in the fleet list (`components/LeftPane.tsx`) shows 4-char ICAO tags instead of full airport names — both the route span (new `onboard-route-{id}` testid) and the "Fly to …" button label + title. Other name displays (in-flight leg, plane location, map popup, open-package rows, toasts) are unchanged. E2E: one new assertion in `e2e/actions.spec.ts` pins the ICAO route on a loaded package
+
 ## v0.39.0 — 2026-09-21 12:02
 - **Maintenance (ISS-069).** Planes wear out and can be repaired: distance-based health, a broken state that burns more fuel, and a repair action that grounds the plane for 3 sim days. New balance constants in `lib/game/catalog.ts` (all ponytail-tunable): `WEAR_PER_KM = 0.005`, `BROKEN_BURN_MULTIPLIER = 1.5`, `REPAIR_COST = 1_500` (flat), `REPAIR_DURATION_MS = 3 × 86_400_000`, plus the pure helper `conditionBurnMultiplier(health)` — exactly 1 above zero health, ×1.5 at/below it
 - **Schema.** Two new `planes` columns in all four places: Drizzle schema (`lib/db/schema.ts`), raw DDL + guarded `ALTER TABLE … ADD COLUMN` migrations in `migrateColumns()` (pre-existing rows backfill to full health / NULL gate, mirroring the weight_kg/special precedent), and the seed insert path — starter plane in `buildSeed` (`lib/game/seed.ts`) and every `buyPlane` delivery start at `health: 100`. New plane status `'repairing'` added to the three pinned unions (schema enum, `PlaneState`, OpenAPI) plus `mapData.ts`'s feature props
