 # Changelog
 
+## v0.3.0 — 2026-09-17 00:32
+- Removed the zoom-driven camera tilt (`lib/camera.ts` pitch curve + the map `move` handler): the map is now always flat/top-down with standard pan/zoom only; deleted `lib/camera.ts` and its unit tests
+- Removed terrain: no more DEM raster source / `map.setTerrain`, and the `?terrain=0` / `NEXT_PUBLIC_TERRAIN` toggles are gone — pure 2D view, no 3D elements
+- MAX_ZOOM 14 → 11: at European latitudes (~52°N) z11 ≈ 47 m/px, so the viewport spans ~90–135 km across a typical desktop width (≈100 km on screen); street-level zoom had no gameplay value
+- `e2e/map.spec.ts`: APP_URL is now `/` (terrain flag removed), MAX_ZOOM mirror updated to 11; PLAN.md map section updated to flat-2D-only
+- Verified: unit suite 8/8; `tsc --noEmit` clean; e2e suite 3/3 green against the rebuilt compose instance (flat view, wheel zoom clamped to [3, 11])

 ## v0.2.9 — 2026-09-17 00:21
 - `data/airports_eu.csv`: multi-airport metro areas reduced to one dot each on the map — Paris→CDG, London→LHR, Moscow→SVO, Milan→MXP, Istanbul→IST, Warsaw→WAW, Brussels→BRU (Rhine-Ruhr keeps both DUS and CGN as distinct cities); dropped 18 satellite airports incl. Orly, Gatwick, Luton, Stansted, Domodedovo, Vnukovo, Zhukovsky, Linate, Caravaggio, Atatürk, Modlin, Charleroi, Weeze, Prestwick, Treviso, Ciampino, Băneasa — 260 → 242 rows; `/api/airports` and the circle layer pick it up with no code changes
 - Verified: unit suite 8/8; `tsc --noEmit` clean; e2e suite 3/3 green against the rebuilt compose instance (`/api/airports` serves 242 features)
