Technical Updates

Add-Ons and Script Engine

• Custom biome names are no longer implied by their filenames. Biome names are explicitly specified via the "identifier" property under the "description" sub-object of their JSON definition.

API

• StructureManager.placeStructure for when the integrity setting is out of bounds (0 - 1).
• PlayerAimAssist.setAimAssistSettings for when the viewAngle setting is out of bounds (10 - 90) or distance setting is out of bounds (1 - 16).
• ItemStack.setNameTag and ContainerSlot.setNameTag for when the nameTag parameter length is out of bounds (0 - 255).
