Changes

v1.3.2 — Refactor & Stability Pass

TL;DR: Internal cleanup release. No new features, no behavior changes, no config changes. Drop in and go — your worlds, portals, inventory groups, and rules all keep working exactly as before.

Why this exists

I planned to ship MC 26.1.2 support next, but the dependencies WorldEngine needs (Yarn mappings + the Fantasy multi-world library) haven't published 26.1.2 builds yet, so that update is blocked upstream.

Instead of waiting, I used the time to audit the codebase. Three of the biggest files were doing too much at once and would be painful to retarget when MC 26.1.2 lands. Cleaning them up now means the eventual MC 26.1.2 release will ship faster and with less risk.

What changed under the hood

  • Inventory system split into focused modules (group registry, on-disk state, event orchestrator) — same on-disk layout, same group commands.
  • Portal system split into command/activation/runtime modules — same ore-frame portals, same /we portal commands, same particles.
  • Command tree (/we ...) split per feature (worlds / rules / mobs / inventory / status / portals) — every subcommand and tab-completion is byte-identical, just lives in dedicated files now.
  • Removed dead code, unused imports, duplicated helpers across the rest of the codebase.

Compatibility

  • Minecraft: 1.21.11 (unchanged)
  • Fabric Loader: 0.18.4+
  • Fabric API: 0.141.3+1.21.11
  • Java: 21
  • Drop-in replacement for v1.3.1. Configs, world data, inventory groups, and portal records are preserved as-is.

What's next

MC 26.1.2 support is queued behind upstream releases. I'm watching:

  • Yarn mappings: meta.fabricmc.net/v2/versions/yarn/26.1.2
  • Fantasy library: github.com/NucleoidMC/fantasy/releases

When both publish 26.1.2 builds, the next release will jump WorldEngine to 26.1.2 (and Java 25). No timeline — depends entirely on upstream.

Reporting issues

If anything misbehaves after the upgrade, please open an issue with:

  • The /we command you ran (or what you were doing)
  • The line from latest.log if there's an error
  • Your config/worldengine/ files if a world or portal looks wrong
