RingWorld

RingWorld 1.0 Beta 1 — Minecraft 1.21.1

• Backports the complete finite, periodic Overworld to Minecraft Java 1.21.1.
• Provides matched Fabric and NeoForge builds requiring Java 21.
• Includes seam-safe gameplay, world generation, structures, portals, maps, compasses, raids, beds, vehicles, block entities, and multiplayer.
• Includes the curved client projection, clouds, sky, textured rims, and the complete-ring terrain Atlas with progressive updates and persistence.
• Passes the local dual-loader build, unit, dedicated-server, two-client, persisted-raid, lifecycle, production-world, and visual matrices.
• Retains the reviewed adaptive live-chunk/Atlas handoff checkpoint.

This is a Beta. Back up worlds and treat untested third-party renderer, world-generation, chunk, networking, and shader combinations as unsupported. RingWorld is required on the server and every client; Fabric requires Fabric API.
