### 6.1.0 ✨
This is a major release. Please back up your worlds and NPC data before updating.
This version contains many improvements, optimizations, and internal changes that
are **not fully compatible** with earlier releases.
⚠️ Breaking changes
- Existing NPCs and their configuration data from versions before 6.1.0 may not
load correctly or may require manual adjustments.
- Internal data formats and some behaviors have been refactored to support new use-cases.
🧩 New modular structure
Easy NPC is now split into three separate mods:
- **Easy NPC** – Bundle that includes both Core and Configuration UI for a
plug‑and‑play experience.
- **Easy NPC: Core** – Lightweight runtime and logic for NPCs, with minimal
dependencies. Intended for servers, modpacks, and developers.
- **Easy NPC: Configuration UI** – Standalone configuration interface for
creating and editing NPCs. Can be installed on clients that need the UI.
🎯 Why this change?
- Allows servers and modpacks to ship only the **Core** mod on the server side
for a leaner setup.
- Reduces memory usage and load times when the UI is not required everywhere.
- Makes development and testing faster by separating UI and core logic.
