0.1.0-beta2 — stability & worldgen fixes

🐛 Fixed

• Worlds now save correctly on disconnect – map readers were closed before the world finished saving, which could abort the save entirely, or silently complete in-flight chunks as empty "ghost chunks" when leaving during terrain generation. Readers are now released only after the world is fully saved (ServerStoppedEvent).
• No more ghost chunks – chunk generation refuses to run without a working heightmap reader: the chunk is left ungenerated and retried later, instead of being saved as empty terrain.
• Generation errors can no longer destroy chunks – every generation step (terrain, biomes, surface, caves, structures, decorations, mob spawning) is guarded: on an unexpected error the chunk keeps safe fallback terrain and the error is logged with the chunk position and a full stack trace (log messages in English).
• Color Mapping screen at high GUI scale – the tab no longer overflows the screen at GUI scale Auto / 4 (small windows). Widgets stay vanilla-sized, long buttons adapt their width, overlong map names are shortened with "…" and show the full name in a tooltip, and the whole tab scrolls when the window is short.

✨ Added

• River and ocean biomes from the water mask – narrow water areas get a river biome, large lakes get an ocean biome (kelp-friendly). River depth adapts to the width of the water area.
• Unified map list (maps[]) – every map is an equal entry in one list; no more "custom vs fixed" split. Old configurations migrate automatically on first start.

🔧 Changed

• Map layer generators always read through the current map reader instance (no stale references after a config reload).
• Slovak in-game log messages with a unified [TIFWORLDGEN] prefix.
• Documentation and in-jar descriptions updated.

0.1.0-beta1 — first public beta

✨ Highlights

• Built-in pure-Java GeoTIFF engine – the mod no longer depends on GDAL or any native library. Reads classic TIFF and BigTIFF (tested with a 14 GB heightmap, designed for 100 GB+ files), stripped and tiled layouts, LZW and Deflate compression. Verified pixel-perfect against GDAL before the switch (336,959 sampled pixels, 0 differences).
• Zero-install experience – no DLLs, no system packages, no .so files. Works on Windows, Linux and macOS out of the box: just drop the jar into mods/.
• Dedicated server support – create worlds with level-type=tifworldgen:void_preset and manage everything in-game (verified on a production Forge server):
  • /tifworldgen info – loaded heightmap size and path
  • /tifworldgen maps – configured maps overview with missing-file check
  • /tifworldgen config – effective configuration overview
  • /tifworldgen reload – reload config and map readers without restart
  • /tifworldgen set <key> <value> – change any setting in-game (saved + applied instantly)
  • /tifworldgen map add/remove – register map files without editing JSON
  • works over RCON for headless servers
• Portable configuration – map paths now support relative paths (resolved against the game directory on both client and server). Configure everything comfortably in singleplayer, then copy config/tifworldgen.json and the tifworldgen/maps/ folder to the server – no edits needed.
• Single-file distribution – the all-in-one jar bundles the library inside (Forge JarJar), so players download exactly one file.

🔧 Changed

• Rewritten map layer readers (HeightMapReader, WaterLayer, ForestLayer, StructureLayer) on top of the new engine – also removes the thread-local dataset handling and its file-handle leaks.
• GDAL completely removed from the repository, build and in-jar descriptions.

🔒 Privacy

• Fully offline: no telemetry, no analytics, no network communication of any kind. The mod only reads the map files the player/admin selects.

📦 Upgrading from alpha builds

• Delete the old tifworldgen/native/ folder from your game directory – it is no longer used.
• If you configured maps by absolute paths, they keep working; relative paths (relative to the game directory) are now recommended.
