Diod v0.1.0.27 — A more natural Kungsholmen shoreline
24 October 2026 | Free pre-alpha

- New games use the refined Kungsholmen v3 terrain, with more varied landforms, natural ground materials and an updated island map.
- Extended detailed coastal terrain around the entire 10 km island perimeter: rounded rocky shores, sheltered banks and beaches, while preserving the approved Fredhäll reference.
- Added 200 fine coastal height tiles, with matching tile boundaries, terrain collision and persistent digging/mining. Nearby detail scales with graphics quality.
- Improved rock grain, mineral variation, wet shoreline materials and water contact/absorption to reduce artificial patterns and angular underwater patches.
- Updated coastal trees and shrubs, lighting and vegetation presentation, and fixed the opening archive notification overlapping the objective HUD.

UPDATING AND SAVES
Close Diod before replacing the complete application/folder. Saves remain in the separate Diod user-data directory. Existing v1/v2 worlds retain their original terrain and progress. To see the new v3 geography, choose Esc → Settings → New game and confirm; the previous run is retained separately on disk. This does not automatically migrate old terrain or provide a run-selection menu.

VALIDATION
Local source: 229 terrain, water, movement and persistence assertions passed. All 200 tiles validated; 318 shared boundaries and 164 outer boundaries matched exactly; 2,018 shoreline samples covered. Native Metal visual review and isolated walking checks completed. Actual Linux export: 249 assertions passed across island-wide coastal sampling/collision/mining/persistence, Fredhäll, coastal bedrock, immutable v2 cliffs, island content, water, ordinary gameplay and tester tools; Diod save/content identity also passed. Windows icon/version and final Mac validation are recorded in the download manifest. Final Mac package: Apple codesign verified all architectures; notarized/stapled; Gatekeeper accepted with quarantine. Exported Mac identity and 53 coast checks passed. Actual packaged Metal Forward+ Low views of Fredhäll/northern bank were inspected, plus a supported 5.68 m normal walk with clear HUD and all scenery queues empty. The headless import emitted a dummy-renderer texture diagnostic; final native package rendering passed. Known Metal LOD-bias warning remains. No fresh Finder-launch UX, Intel Mac or FPS benchmark was performed.

KNOWN LIMITATIONS
- Windows and Linux desktop graphics and Intel Mac gameplay have not been playtested for this release. Windows publisher signing is not configured; Smart App Control may block the download.
- Local Apple M4 Metal testing covered 16 perimeter views, selected final Low/Medium rechecks and a short normal walking test, not every metre or a performance benchmark.
- Pre-alpha visuals and performance remain in development. Fast tester-camera jumps may need time for scenery to load.
