[1.21-1.21.11-1.0.0] - 2026-01-06

Changed

• Extended MC support: Now supports Minecraft 1.21 through 1.21.11 (previously 1.21-1.21.5)
• Updated loader version ranges:
  • Forge: [51,) to support both Forge 51.x (MC 1.21) and 61.x (MC 1.21.11+)
  • NeoForge: [4,) to support both NeoForge 4.x (MC 1.21) and 21.11.x (MC 1.21.11)
  • Fabric: API requirement changed to >=0.102.0 to support both MC 1.21 and 1.21.11
• Updated README: Complete rewrite to be mod-specific with installation, compatibility, build/test instructions, and cross-loader verification rule
• Updated agents.md: Added critical cross-loader change verification section with real-world example and comprehensive checklist

Fixed

• Fixed NeoForge API breaking change: FMLLoader.isProduction() was removed in NeoForge 21.11+, simplified isDevelopmentEnvironment() to return true as safe default
• Fixed Fabric metadata: Updated fabric.mod.json to accept Fabric API 0.102.0+ instead of requiring 1.21.11-specific version, ensuring compatibility across MC 1.21-1.21.11
• Fixed Forge/NeoForge metadata: Corrected loader version ranges in gradle.properties to support full MC version range
• Branch renamed: multi/1.21-1.21.5 → multi/1.21.x to reflect broader version support

Documentation

• Added comprehensive cross-loader verification rule in agents.md with explicit checklist for checking metadata files
• Added lesson learned example documenting the Fabric API metadata oversight and fix
• Updated agent memory with critical multiloader development rules
