High Water

High Water 1.1.0 - Minecraft 26.3

English advancement text. Install only one language build.

• Updated world generation for Minecraft Java Edition 26.3 (data pack format 121.0).
• Preserved sea level Y=256, disabled aquifers, vanilla biome diversity, all 20 advancements, and the grass-block trade.
• Migrated advancement predicates and the buried-treasure trigger to the new format.
• Disabled the new abandoned camps alongside the existing disabled surface structures.

Installation

Enable this ZIP before creating a new world. For an existing High Water world, make a backup, replace the old pack, and fully restart the world in 26.3. Existing chunks keep their blocks; new chunks use 26.3 generation. Use High Water 1.0.0 for Minecraft 26.2.

Validation

Both language builds passed loading with the official Minecraft 26.3 game code, including all 20 advancements, both functions, the trade, and structure settings. Base terrain was checked at 147 coordinates across three seeds per build. A graphical gameplay session was not performed.
