Full Changelog: https://github.com/DemonZ-Development/DZEconomy/compare/v…

[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. ---

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. ---
