+## v0.43.0 — 2026-09-21 15:57
+- **Wear rate reduced 10× per ISS-085** — `WEAR_PER_KM` in `lib/game/catalog.ts` drops from 0.005 to 0.0005, so plane maintenance status degrades 1/10th as fast (~13 mid-range hops → ~130 hops to break a full-health plane)
+
 ## v0.42.0 — 2026-09-21 15:02
 - **Auto-refuel on dispatch (ISS-082).** Manual refueling is gone — planes top up automatically at dispatch, so a grounded plane can always start any leg that fits a full tank when cash allows. `flyPlane` (`lib/game/actions.ts`) tops the tank to `min(maxFuel, max(fuel, 1.5 × required))` before departure — the same target/price terms as the removed forFlight mode: liters × FUEL_PRICE_PER_L minus the rep-scaled discount (v0.38.0), deducted from cash; unaffordable → 409 `insufficient funds` with nothing mutated, and a leg that doesn't fit even a full tank still 409s `insufficient fuel` (the backstop). The engine's auto-chain (`deliverPackages`, `lib/sim/engine.ts`) does the same at landing: when the next queued leg exceeds the landed fuel it tops up to the identical target when cash allows and chains anyway — only an unaffordable top-up grounds the plane with the queue kept intact
 - **REMOVED** `POST /api/planes/:planeId/refuel` (route + route tests), the `refuelPlane()` action + `RefuelOptions` (`lib/game/actions.ts`), the left-pane "Refuel to full" section and per-leg Refuel button with their dead state/derived values (`components/LeftPane.tsx`), and the OpenAPI `/api/planes/{planeId}/refuel` path + `RefuelRequest` schema — endpoint count 14 → 13, stale refuel mentions reworded in info/state/queue/repair descriptions, and fly's description + 409 now document the auto-refuel
