3.1.1+1.20.1

⚠️ Read this before updating

This release is a major technical overhaul and is not backwards compatible.

• Requires the matching Spell Engine and More RPG Library releases. This version will not run on Spell Engine 0.9.x, and mods built against 0.9.x will not work alongside it.
• Update the whole set together. Spell Engine, More RPG Library and every RPG Series mod must be on matching versions. Mixing in an older add-on will break at startup or misbehave in play.
• Spell books must be re-obtained. Spell books from an older world no longer carry valid spell data. Re-craft them, or re-bind their spells at the Spell Binding Table.

Back up your world before updating.

• Thanks to Daedelus for the PR!
• Ported to Minecraft 1.20.1 (Fabric + Forge 47, no Forgified Fabric API). NeoForge is replaced by Forge on this line; the same Forge jar also loads on NeoForge 1.20.1.
• Requires the matching 1.20.1 releases of Spell Engine (1.10.5), Spell Power (1.6.0), More RPG Library (2.7.2) and Armor Model API (1.0.0).
• Every registry write goes through Forge's RegisterEvent window, so the mod also boots on Forge 47.0-47.3 and on NeoForge 1.20.1, which never unlock the vanilla registries.
• The Billporon armor is now always registered, so a server without Armory RPGs starts (its set bonus used to fail to load and abort the startup). Crafting it still requires Armory RPGs.

Accepted 1.20.1 limitations

• Knuckles no longer carry #minecraft:enchantable/durability / #minecraft:enchantable/sharp_weapon (those tags are 1.21-only); they are sword items, so Unbreaking and Sharpness still apply.
• Armor opts into #minecraft:trimmable_armor directly, replacing the 1.21-only #minecraft:{head,chest,leg,foot}_armor tags, so the sets stay trimmable at a smithing table.
• 1.20.1 has no item data components: equipment-set membership and the custom knuckle models are carried as item NBT instead. Functionally identical, but not readable by 1.21-era component tooling.
