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
