NeoEssentials v1.0.2 - Major Configuration & Shop System Update

Configuration system overhaul and shop cross-linking fixes with clean migration required

Released: August 8, 2025

Overview

Version 1.0.2 introduces a completely redesigned configuration system for NeoEssentials that provides better organization, enhanced validation, and improved performance. Additionally, this release includes a complete shop system overhaul that fixes critical cross-linking bugs using ChestShop-inspired methodology. This update requires a clean migration from previous versions to ensure compatibility with the new system.

⚠️ CRITICAL: Clean Migration Required

Before updating, you must delete your existing NeoEssentials configuration files:

Windows Users:

1. Stop your server completely
2. Delete: config\neoessentials\
3. Delete: neoessentials\ (if it exists)  
4. Update the mod JAR
5. Start server (new config auto-generates)

Linux/Mac Users:

# Stop your server first
rm -rf config/neoessentials/
rm -rf neoessentials/
# Update mod JAR and restart server

Why is this necessary?

• Complete configuration architecture redesign
• New file structure and validation system
• Enhanced security and backup features
• Incompatible configuration formats

New Features

Enhanced Configuration System

Completely rebuilt configuration management
