Raft Ocean 0.13.8 preview

Raft Ocean 0.13.8 is a preview pre-release for Minecraft Java 26.3. It includes the development updates since 0.13.0 and keeps the story open-ended.

Requirements and installation

• Minecraft Java 26.3, NeoForge 26.3.0.48-beta, 64-bit Java 25.
• Install only raft_ocean-0.13.8.jar in mods. Remove older Raft Ocean JARs.
• Every multiplayer client and server must use 0.13.8 (movement handshake13.8).
• Optional JEI: 31.9.0.58 for Minecraft26.3/NeoForge; install separately.
• Sources JAR and addon SDK are for developers. Minecraft, NeoForge, Java and JEI are not bundled.
• Back up existing worlds/configs before updating. Create an Ocean World for raft survival; larger island generation appears only in new chunks.

Added since 0.13.0

• Battery-powered Raft Juicer: four food portions, Blend/Pause/Serve controls, saved batches, separate glass serving, three original drinks, reusable glasses, custom models, recipe data and optional JEI links.
• Salvage Compactor: mixed surplus materials become tradeable bales, with five new outpost purchases and saved-stock migration.
• Deliberate single-batch cooking, saved queue/progress and an automatic-processing compatibility option.
• Wind-limited shared sail drive, engine foundation-load bands and clearer navigation feedback. User-selected engine/sail/paddle base speeds remain1.5/1.0/1.8m/s.
• Mounted survey receiver, three-antenna setup, battery power, radar and a persistent expedition notebook with28field notes.
• Seven original story schematic discoveries, eight gated advanced projects, harder material-study batches and larger staged story islands. Earlier learned research is retained; the story remains open-ended.
• Configurable ten-minute shark/five-minute bird delays and Peaceful protections retained. Addon API3 retained.

Downloads

• SHA256SUMS.txt and ZIP checksum sidecars — integrity verification.

Verification

The published runtime JAR is the tested artifact from source commit55ce5c7f275b4ee3703e04d525647605e158e86b; SHA256:

1c83d0e4157438c58f03865d471e3ae1c41690fb933014d3b5f2e6694f3874b2

Full build/bootstrap passed; fresh Ocean World checks passed9,873assertions, including127juicer assertions. Crafting263,891, research784, movement/collision, models, localization and package checks passed. Native parser accepted966models; package coverage is172items/787blocks/7entity renderers. SDK compilation and ZIP/checksum integrity checks passed. This does not establish bug-free live gameplay.

Known limits

• Live GUI/JEI appearance, real co-op latency, older user saves, large-raft performance and full survival balance still need playtesting. Earlier reported movement/collision issues require user confirmation; rotating collision uses conservative axis-aligned approximations.
• Juicer uses native portable batteries. Wired/foreign power, bonus-water reserves and invalid-recipe leftovers are absent. Glasses are intentionally reusable; dismantling spills an unserved drink.
• Coins, trading reputation/special fish and a recycling JEI category remain future work. Cooking retains existing two-food/water/bowl recipes, without four-food cooking pads or post-cooking bowl collection.
• Foreign machines need dedicated moving-raft adapters. No universal technology-mod compatibility is claimed. NeoForge itself is beta.
• New island sizes affect newly generated chunks. The seven-destination story intentionally remains unresolved.

All models, lore and sounds are original. No Raft game assets or text are bundled. See the included CHANGELOG.md, KNOWN_ISSUES.md and RELEASE_VERIFICATION.md for details.
