ServerManagement+ v2.1.2-b3 — First Public Beta for Minecraft 1.21.1

This is the first public beta of ServerManagement+ for Minecraft 1.21.1. It consolidates all improvements from the internal v2.1.1 beta cycle (Beta 1 through Beta 3) into a single release under the new v2.1.2 version line.

🏗️ Architecture & Up-Porting

• Up-ported from 1.20.1 to 1.21.1: Successfully migrated all architectural changes, UI overhauls, and bug fixes from the mc/1.20.1 branch.
• MultiLoader Parity: Full compatibility across Fabric, Forge, and NeoForge loaders on 1.21.1.
• NeoForge Compatibility: Replaced legacy net.minecraftforge.fml hooks with net.neoforged.fml equivalents.
• CustomPacketPayload Migration: Completely migrated the legacy packet system to 1.21.1's CustomPacketPayload and StreamCodec architecture.

✨ New Features & Major Overhauls

Economy Engine

• The Global Census Engine (Economy Rewrite): Replaced the old event-driven economy with a tick-based differential scanner. The server now continuously scans chunk containers and offline player inventories to perfectly synchronize real existence with market value — fundamentally solving economy duplication glitches and hyper-inflation.
• Creative Mode Market Protection: Items spawned via Creative Inventory or /give are now tagged and ignored by the Census Engine, preventing admins from unknowingly crashing the economy.
• Dynamic Scarcity & Capital Scaling: The economy dynamically adjusts based on the server's STARTING_BALANCE. Uncraftable items (like Dragon's Breath or Heart of the Sea) automatically receive scarcity multipliers based on real server supply.
• Comprehensive Economy Stabilization: Overhauled the economy engine's scaling logic to prevent price collapses. Intrinsic item values no longer crash to the $0.50 floor when players spend their starting balances. Inflation now only scales prices upwards as server wealth grows.
• Dynamic Pricing Caps: Items with zero supply no longer skyrocket to multi-million dollar prices. Introduced smoother scarcity curves and hard price caps for unknown items.
• Supply/Demand Curve Smoothing: Abundant building materials retain much more of their value. The aggressive supply deflation penalty has been significantly softened.
• Reverse Crafting Loop Fixed: Removed recursive recipe calculations that caused raw material values to spiral downwards. Prices now strictly flow upward from raw materials to crafted products.

Node Editor & Daily Tasks

• Immersive Fullscreen Node Editor: Overhauled the Daily Task Template creator into a stunning fullscreen experience with a dynamic glowing grid, drag-to-connect interactive pins, and cubic bezier connection lines.
• Multiple Item Rewards: Daily Task Templates now support assigning unlimited items as rewards.
• Dynamic HUD Transitions: The Daily Tasks HUD overlay uses smooth mathematical interpolation for vertical transitions. Long task descriptions are intelligently truncated.

Performance Orchestration

• Zstd Packet Compression: Added zstd-jni library with ZstdPacketCompressor for zero-copy compression directly in the Netty pipeline.
• Server-Side Optimization Suite: Chunk PreGenerator (spiral matrix algorithm), MSPT Monitor (throttles at 45ms), Dynamic Workload Scaler, and Chunk Unload Delay Manager.
• Client-Side Rendering Engine: LRU Chunk Cache (up to 10k unloaded chunks), Fake Chunk Injector, Smart Packet Queue (FOV-prioritized), and Async Occlusion Culler.
• Distant Horizons Deep TPS Synergy:
  • Chunk Gen Throttle — TPS-reactive view-distance reduction with hysteresis to prevent oscillation.
  • Movement Leniency — Relaxes "moved too quickly" detection during TPS drops or when DH is active.
  • Dynamic View Distance — Emergency view/simulation distance reduction during critical TPS drops.
  • DH Sync Coordinator — Bridges SM+ server-side chunk pre-generation with DH's LOD invalidation system.
• JVM GC Flag Patcher: Detects suboptimal GCs and allows admins to auto-patch launch scripts with optimized ZGC flags (Java 21+). Accessible via chat notification on join or Performance Settings GUI.
• Advanced Performance Diagnostics: JMX Allocation Tracker (MB/s), GC health banners, DH version detection, real-time allocation rate, and total GC pause times in the overhauled Stats GUI.
• 7 New Config Options: Full control over all DH synergy systems — toggle each independently, configure chunk reduction limits, movement leniency multiplier, and view distance reduction amount.

Updater System

• SM Updater Full Integration: Server Updater card on Admin Dashboard, /sm update command, client-side TitleScreen interceptor for automatic update prompts, and background server update checking.
• Update Source Control & Beta Channels: Players can customize update sources (CurseForge/Modrinth) and channels (Release/Beta) with smart fallback.
• Updater Log Cleanup: updater_jvm_error.log, updater_jvm_output.log, and updater_log.txt are now automatically cleaned up only after a successful update is confirmed. Failed update logs are preserved for debugging.

Economy UI & Market

• MineBay Enhancements: Restructured search box UX, fixed focus bugs, seamless search across tabs, proper empty state for zero-result searches.
• Trade Blacklist Editor: Full focus/keyboard event routing, hold-to-delete animation, CTRL+Click multi-select, autocomplete rendering fixes, and strict enforcement in MineBayScreen.
• Unsaved Changes Protection: Confirmation dialog when editing templates, configuring rewards, or changing settings prevents accidental data loss.
• Enforced Module Toggles: /minebay and /minestacks now respect both global economy state and granular config toggles.

Other

• Floating Logo Button: Freely draggable logo on Main Menu and Pause Screen with smooth edge-bounce physics. Dynamic glowing notification dot for pending updates. OP-2 gated on Pause Screen.
• Anti-Tamper DRM: Compile-time API key steganography for CurseForge API keys.
• Enhanced /sm performance Command: Real-time status of all DH synergy systems.

🐛 Notable Bug Fixes

• Node Graph Dragging: Fixed drag events being swallowed by vanilla container slot interaction checks.
• Nested UI Focus Loss: Fixed Cash Reward text box failing to unfocus the item search field in the Node Editor.
• Template Editor Fullscreen Fix: Fixed Save/Cancel/Fullscreen buttons being unclickable in fullscreen mode.
• Fullscreen Editor Persistence: Fixed fullscreen background persisting when switching tabs.
• Template Saving & Rewards: Fixed templates failing to save with item-only rewards (no cash).
• Template Search & Scrolling: Fixed search box not filtering and added mouse wheel scrolling.
• Network Stability (EncoderException): Fixed String too big disconnects by removing restrictive string length bounds on network packets.
• "Moved too quickly" Spam Fix: Dynamically increased movement validation tolerance based on server load.
• Chunk Gen Throttle Oscillation: Added deadband hysteresis to prevent view distance oscillation under heavy load.
• Qty Field Focus Fix: Fixed unselectable Qty text field on Free Reward Tab.
• Unsaved Changes Overlay Rendering: Fixed GUI layering glitches with dim overlay rendering.
• F3 Debug Screen HUD Overlap: HUD auto-hides when debug mode is active.
• MineBay & Economy UI Keybind Fixes: "E" key no longer closes the UI while typing in search/price fields.
• Crafting Cycle Feedback Loop Breaker: Resolved exponential price divergence for modded items with reversible crafting recipes.
• Economy & Feature Toggle Architecture Fix: Fixed 5 critical issues in the disable toggle system across all loaders.
• Client-Side Price Sync: Fixed client showing different prices than the server.
• Fabric Access Widener Fix: Fixed IllegalAccessError crash when opening MineStacksScreen on Fabric due to missing accessWidener declaration in fabric.mod.json.
