Keystone Expansion — Pufferfish Skills

Changelog — v1.0.1 (MC 1.21.3+)

✅ Compatibility

• Added full compatibility with Minecraft 1.21.3+ (changes introduced since 1.21.2 regarding attribute IDs).
• Loaders supported (unchanged): Fabric / Forge / NeoForge.

🔧 Fixes

• Fixed datapack loading failure: skill_tree_for_pufferfishs_skills no longer crashes with:
  • Unknown attribute minecraft:generic.*
  • Unknown attribute puffish_skills:player.*

🧬 Attribute Registry Migration (1.21.3+)

Vanilla (Minecraft) attributes

• Migrated all legacy minecraft:generic.* identifiers to the new registry format:
  • minecraft:generic.attack_speed → minecraft:attack_speed
  • minecraft:generic.armor → minecraft:armor
  • minecraft:generic.armor_toughness → minecraft:armor_toughness
  • minecraft:generic.max_health → minecraft:max_health
  • minecraft:generic.knockback_resistance → minecraft:knockback_resistance
  • minecraft:generic.luck → minecraft:luck
• Updated minecraft:player.block_interaction_range → minecraft:block_interaction_range

Pufferfish attributes

• Migrated legacy Pufferfish Skills attribute namespace to the correct mod registry:
  • puffish_skills:player.* → puffish_attributes:*
  • puffish_attributes:player.* → puffish_attributes:*

📦 Notes

• This release targets MC 1.21.3+ only.
  If you still need MC 1.21.1, keep using v1.0.0 (separate jar recommended).
• Make sure Pufferfish’s Attributes is installed, as skill rewards now reference puffish_attributes:*.
