AcidIsland

🎁 What's new

AcidIsland 2.0.0 embraces Minecraft 26.2's new sulfur pools as the signature look of the acid ocean. The whole sea is now acid-green sulfur water, dotted with bubbling sulfur vents that gas the surface with nausea and periodically erupt as geysers. The ocean floor has been livened up with gravel, tuff, magma, sulfur, and cinnabar, and a new spruce-themed "Sulfur Spring Refuge" starter island fits the harsher landscape. Vanilla structures are now on by default, so trial chambers generate buried beneath the ocean floor — giving players a real reason to dig down.

Everything is version-aware: the same jar runs on Minecraft 1.21.x servers, where the 26.2 features quietly disable themselves and the water falls back to the classic warm ocean.

✨ Highlights

🌊 Acid-green sulfur water (PR #176)

• ⚙️ The default overworld biome is now SULFUR_CAVES (Minecraft 26.2+), turning all water acid-green with matching green fog
• On servers older than 26.2 the biome does not exist and the world automatically falls back to WARM_OCEAN
• Existing servers keep their configured biome — this applies to new installs, or set default-biome: SULFUR_CAVES yourself

🌋 Sulfur vents and geysers (PR #176)

• Potent sulfur vents generate just below the sea surface: bubbles, a nausea gas cloud on the surface, and periodic geyser eruptions
• Four natural shapes — chimney, mound, twin, and spiky crag — with random variation so no two vents look alike
• ⚙️ Per-chunk chance is configurable via the new world.sulfur-vent-chance option (default 10%); requires Minecraft 26.2+, ignored on older servers

🪨 Varied ocean floor (PR #176)

• The barren sand floor is now a weighted mix of sand, gravel, sandstone, and tuff, with bubbling magma blocks and — on 26.2+ — scatterings of sulfur and cinnabar, echoing vanilla sulfur springs
• Older servers get gravel and tuff in place of the 26.2 blocks, so the floor is more interesting everywhere

🏝️ New "Sulfur Spring Refuge" island (PR #176)

• A new blueprint bundle in the island-selection panel: a hardy spruce outcrop with leaf litter, eyeblossoms, a wither rose, podzol, a tuff sanctum below, and a goat
• Same utilitarian starter kit as the cherry grove island (barrel, crafter, spruce sapling), built entirely from 1.21-safe blocks

🗝️ Structures on by default (PR #176)

• ⚙️ world.make-structures now defaults to true: trial chambers and other underground structures generate buried beneath the ocean floor, and the trial key in the starter kit is earnable
• Only affects newly generated worlds/chunks; existing configs keep their current setting

⚙️ Compatibility

✔️ BentoBox API 3.14.0 ✔️ Minecraft 1.21.11 – 26.2 (sulfur features require 26.2+) ✔️ Java 21

🔺 Updating — important notes

🔺 World generation changes. The new water biome, vents, ocean floor, and structures all bake in at chunk generation. Existing worlds keep their current look in explored chunks; for the full 2.0.0 experience start a fresh world (or expect a visible seam at old chunk borders).

⚙️ Existing configs are not changed. Your current config.yml keeps its saved values. To adopt the new defaults on an existing install, set default-biome: SULFUR_CAVES, make-structures: true, and add sulfur-vent-chance: 10 — or delete the config to regenerate it.

🔺 New blueprints on existing installs. BentoBox only extracts bundled blueprints into a missing blueprints folder. On an existing install, copy sulfur-spring.blueprint and sulfur_spring.json from the jar into plugins/BentoBox/addons/AcidIsland/blueprints/ to see the new island option.

📥 How to update

1. Stop the server
2. Back up your BentoBox folder
3. Drop the new jar into the addons folder and remove the old one
4. Review the config notes above
5. Start the server
