KoHs Offhand Whitelist

Changelog - 1.21.6 - 1.21.11

Code Changes

• Preserved the same unified GUI system across this range (responsive layout, custom tab bar, animated transitions, unified controls).
• Maintained OFF-state interaction model (centered toggle + helper message panel).
• Kept whitelist/preset feature parity with the earlier ranges.
• Standardized player-facing strings in English for consistency.

Migration Notes

• Migrated GUI texture rendering to modern pipeline usage (RenderPipelines.GUI_TEXTURED) for this API generation.
• Manifest dependency declaration was migrated from exact Minecraft target to range-based compatibility (>=1.21.6 <=1.21.11).
