Full Changelog: https://github.com/DemonZ-Development/DZEconomy/compare/v2.1.0...v2.1.1

[2.1.0] — 2026-05-28

Added

• Server Adapter System — Version detection and platform-specific behavior via ServerAdapter interface
• LegacyServerAdapter — Explicit Class.forName() SQLite driver loading for Java 8-16 (fixes "No suitable driver found" on older servers)
• ModernServerAdapter — SPI-based driver discovery with Class.forName() fallback for Java 17+
• ServerAdapterProvider — Automatic Java version detection and adapter selection
• SLF4J Shading — Relocated to prevent runtime linkage conflicts with other plugins
• FoliaAdapter migration — MigrationManager now uses FoliaAdapter instead of direct Bukkit.getScheduler()

Fixed

• SQLite JDBC driver not loading on legacy Paper/Spigot servers (classloader SPI issue)
• EntityDeathListener dead code — requirePlayerKill=false setting had no effect due to redundant null check
• Java 14 switch expression replaced with traditional switch for broader compatibility
• Shading gaps — SLF4J, CheckerFramework, and ErrorProne now properly relocated
• Stale module-info.class excluded from JAR
• Stale native-image.properties excluded from JAR
• Empty META-INF/versions/9/org/ directories cleaned from JAR
• ServerAdapterProvider null safety — robust handling of edge cases in version detection

🚀 DZEconomy v2.0.0 — The Ultimate Performance & Folia Rewrite

We are thrilled to present DZEconomy v2.0.0, a ground-up architectural rewrite of the plugin. DZEconomy has been completely overhauled to deliver elite performance, full thread-safety, 100% Folia compatibility, and a premium multi-currency economy experience for modern Minecraft servers.

✨ Key Features & Enhancements

1. 🪙 Multi-Currency Architecture

• Three Independent Currencies: Built-in support for Money ($), MobCoins (★), and Gems (◆).
• Custom Formatting & Limits: Define custom decimal places, starting/max balances, display symbols, and transaction bounds per currency.
• Currency Conversion: Convert seamlessly between currencies via /economy convert with configurable conversion rates and customizable transaction fees.

2. ⚡ Elite Performance & Storage Scaling

• In-Memory Balance Cache: Completely eliminated flat-file O(N) directory scans for /baltop leaderboards. Caching layer is maintained in real-time.
• Robust Database Backends: Supporting flat files, connection-pooled MySQL (via HikariCP), and connection-optimized SQLite (using Connection WAL mode and automatic PRAGMA sync flushes to prevent concurrency locks).
• Live Storage Migration: High-speed, seamless data migration between storage backends using /economy migrate (with automated pre-migration safety backups).

3. 🌿 100% Folia & Paper Compatibility

• Asynchronous Execution & Scheduling: Fully compliant with Folia's region-based multithreaded scheduler. All operations (auto-saves, update checking, database queries) are delegated to async/region context wrappers.
• Memory & Classloader Leak Prevention: Safe integration closures for PlaceholderAPI and LuckPerms prevent memory leaks on server reloads/plugin disable.

4. ⚔️ PvP Loot & Combat Tag Integration

• PvP Loss Percentages: Configurable balance drops/steals upon player deaths with minimum safe retain thresholds.
• Active Combat Tagging: Prevents economic evasion or money transfers during PvP combat using a smooth Action Bar countdown timer.

5. 🎯 Extensible Integrations & APIs

• Advanced PlaceholderAPI: High-speed Cached placeholders for balances, limits, and ranks.
• LuckPerms Rank Multipliers: Dynamically apply multipliers to Mob Rewards based on LuckPerms groups.
• Public Developer API: DZEconomyAPI registered in Bukkit's ServicesManager for robust third-party plugin integrations.

📋 Changelog

For the complete list of changes, please refer to the CHANGELOG.md.

🚀 DZEconomy v1.2.0 — Organized. Integrated. Polished.

✨ What this version adds

🏗️ Restructured internal packages for improved maintainability and clarity — API and implementation layers are now cleanly separated.

📦 JitPack support: DZEconomy can now be added as a Maven dependency instead of manual JAR installations.

🔌 Refactored and enhanced API: plugin hooking and third-party integrations are smoother and easier to use.

⚙️ Runtime enhancements: automatic update checker; optional “auto-update disable” feature for server owners who prefer manual control; suppression of PvP/PvE money-request GUI pop-ups to avoid combat interruptions; general visual polish and minor performance tweaks.

🧩 Developer-friendly: easier to build upon, extend, and maintain for plugin authors.

🎯 Why you should download it

If you run a Minecraft server or develop plugins and you’re using DZEconomy, this upgrade will reduce headaches, improve integration into your ecosystem, and deliver a cleaner experience for your users or co-developers.

🔍 Important upgrade notes

Check compatibility: If you’ve made custom extensions or hooks into the previous API, you may need to adjust your code due to the refactoring.

Backup your data before upgrading: Always a smart move when changing core systems.

Read the API changes in the documentation to smoothly transition any dependent plugins.

Thanks for using DZEconomy. Your feedback keeps the plugin evolving.
