Rivencraft 26.3 beta 1.0.1.65-beta.1

This beta collects the player-tested port slices since 1.0.1.54-beta.1. It is not yet feature-complete with the Minecraft 1.21.1 release.

Age generation

• Added authored structure pages: Villages, Mineshafts, Strongholds, Trial Chambers, Buried Treasure, Shipwrecks, Ocean Ruins, Pillager Outposts, Ruined Portals, Nether Fossils, Ancient Cities, Trail Ruins, Nether Fortresses, Bastions, and 26.3's Abandoned Camps. Dungeons remain their separate feature.
• Fixed the early structure-biome check so authored structures can generate outside their native biome restrictions, within the supported terrain rules. Repeated structure pages increase density up to the current authoring cap.
• Added Caves and Ravines feature pages through 26.3's native carving stage. These are distinct from Cave terrain; Flat/Void support remains pending.
• Added Poplar Trees, Fallen Poplar Trees, Red Shrubs, and Shelf Mushrooms. Shelf Mushrooms find exposed logs at any height, including log Tendrils in Void terrain. No Trees page is required.
• Added Normal, Fast, Slow, Off, Always, and Storm weather pages. Each Age has independent saved weather data and timers; its policy does not change the Overworld or other Ages. Cave terrain keeps weather disabled.

Fixes and feedback

• Non-Cave Descriptive Book arrivals trace actual blocks down from maximum build height instead of using a Flat-layer shortcut or only a heightmap. The search stops at roofs/fluids rather than selecting underground pockets. Leaves count as footing; submerged footing is rejected. Fallback platforms sit above obstructions, with floor Y=63 in an empty Void.
• Stored surface-Age Star Fissure arrivals are rechecked from above. Cave terrain still searches down from Y=64, and Linking Books retain exact bound destinations.
• Restored Legacy linking sounds and successful-link cloud bursts. Disarm and Intra-Linking use their respective sounds. Star Fissure return audio also plays after arrival so a dimension switch does not discard it.
• Fixed weather-only authoring, including Link Panel + Storm books: non-biome pages no longer get interpreted as biome IDs.
• Unsupported pages now have a red tint and availability tooltip. Supported pages and their descriptions reflect the implemented 26.3 behavior.
• Added operator weather and surface diagnostics for testing.

Current limits

• Only the supported page/terrain combinations can be bound. Most repeated features are capped at 32; vegetation uses a combined 32-page limit. The full 1.21.1 grammar recovery and instability systems remain unported.
• Pageless books currently randomize terrain and biome distribution, not the complete feature/environment list. Omitted weather currently means Normal.
• Base carvers do not carve authored solid volumes added after 26.3's combined terrain operation. Previously generated chunks are not regenerated.
• The full writing/discovery loop, celestial/lighting systems, crystal portals, instability, and optional-integration parity remain in progress. Creative availability alone does not mean a page is supported; check its tooltip.
• Vanilla /weather targets global server weather, not the independent Age policy. Biomes retain their normal precipitation rules.

The player reported in-game passes for these slices. Build/static checks passed. Targeted disposable dedicated-server checks covered all six weather policies, Overworld isolation, unload/reload and restart persistence, weather-only page compilation, and dry surface/leaf spawn probes. This is not a claim of full dedicated-server or optional-mod regression coverage. Test servers were stopped and their temporary worlds removed.

Requires Minecraft 26.3, NeoForge 26.3.0.99 or a compatible 26.3 build, and Java 25. This build does not require Dynamic Dimensions or Bad Packets. Keep it separate from the 1.21.1 build and saves. Back up entire worlds before updating; beta-save compatibility is not guaranteed.
