Ultimate Tweaks

[2.0.13] — 2026-10-16 — Minecraft 1.21.1

✨ Added

• Transformation, in-world recipes for KubeJS (only active when KubeJS is installed): an item in a fluid becomes other items, a fluid becomes another fluid when catalysts fall into it, an item that burns, an item that is hit by an explosion and a block that explodes can all turn into the items you choose. They also work from a datapack. See docs/Transformation.md.
• Transformation recipes show up in JEI, EMI and REI, one category per type. Lava, flint and steel, fire charge and TNT open the categories where they are used.
• Astral Sorcery 2.0.2 support. The generation of its structures (focal point, obliteration, dig site, moon dial, column and rotunda) can be switched off, spaced differently or moved to other biomes from the new ultimatetweaks-common.toml.
• Astral Sorcery focal transmutations: cobblestone into stone, stone into gravel, gravel into sand and, with Ex Deorum, sand into dust.
• SpongeBob and Patrick can now be found in Astral Sorcery shrine chests.

⚔️ Changed

• The translations are generated with datagen. Argentine and Mexican Spanish (es_ar and es_mx) are now included, so their text no longer falls back to English.
