[1.0.2] - 2025-12-22

Fixed

• Fixed armor toughness detection failing on Minecraft 1.21.11 (was returning 0.0 instead of actual toughness values)
• Fixed armor toughness detection broken on Minecraft 1.20.1 after initial 1.21.11 fix attempt
• Fixed armor toughness detection broken on Minecraft 1.21.1 after initial 1.21.11 fix attempt
• Heavy armor detection (toughness ≥ 9) now works correctly on all supported versions

Added

• New FearOfHeightsEffect_1_20_1 class for MC 1.20.1-specific armor toughness detection
• New FearOfHeightsEffect_1_21_1 class for MC 1.21.0-1.21.10 specific armor toughness detection
• New FearOfHeightsEffect_1_21_11 class for MC 1.21.11+ specific armor toughness detection
• New StatusEffectHandler utility class for improved effect management
• New VersionConstants utility class for version-specific constants
• Version-specific JAR outputs: acrophobia-1.0.2+mc1.20.1.jar, acrophobia-1.0.2+mc1.21.1.jar, acrophobia-1.0.2+mc1.21.11.jar

Changed

• Replaced fragile reflection-based armor toughness detection with direct API access
• Each Minecraft version now has its own implementation class with proper attribute access:
  • MC 1.20.1: Uses EntityAttributes.GENERIC_ARMOR_TOUGHNESS
  • MC 1.21.0-1.21.10: Uses EntityAttributes.GENERIC_ARMOR_TOUGHNESS
  • MC 1.21.11+: Uses EntityAttributes.ARMOR_TOUGHNESS (renamed constant)
• Updated Minecraft version compatibility range: >=1.20.0 <1.22.0 (previously >=1.20.0 <1.21.0)
• Improved code architecture with cleaner inheritance chain and better separation of concerns
• Enhanced build system with true multi-version support (separate version-specific classes per version)
• Updated author name in mod metadata: "MidnightSP"

Technical Details

• New Classes: 3 version-specific implementations + 2 utility classes
• Removed: Complex reflection-based fallback code from base class
• File Size: Varies by version (~300-400KB per version-specific JAR)
• Compilation: Each version compiles independently with its own Fabric Yarn version
• Version Detection: No runtime version checking needed - compile-time separation ensures correct APIs

Version Support

• MC 1.20.1: ✅ Fully supported and tested
• MC 1.21.0-1.21.10: ✅ Fully supported and tested
• MC 1.21.11+: ✅ Fully supported and tested

[1.0.1] - Previous Release

Features

• Initial multi-version support for Minecraft 1.20.x and 1.21.x
• Basic armor toughness detection (using reflection)
• Heavy armor detection feature (Level I→V jump after 10 seconds with armor > 20 OR toughness ≥ 9)
• Single unified JAR per version range (1.0.1-mc-1.20.x.jar, 1.0.1-mc-1.21.x.jar)

Known Issues

• MC 1.21.11 armor toughness detection broken (returns 0.0 instead of actual values)
• Relies on reflection which is fragile across Minecraft versions

Version Support

• MC 1.20.x: ✅ Working
• MC 1.21.x: ⚠️ Partially working

   • Use acrophobia-1.0.2+mc1.20.1.jar for MC 1.20.1
   • Use acrophobia-1.0.2+mc1.21.1.jar for MC 1.21.0-1.21.10
   • Use acrophobia-1.0.2+mc1.21.11.jar for MC 1.21.11+
2. Remove old JAR file from mods folder
3. Add new JAR to mods folder
4. Launch game - no config changes needed, old worlds work as-is
