Full NeoForge 26.2 support

All commands working: /lon tps, /lon memory, /lon entities, /lon report, /lon autopregen, etc.

HUD permanently removed

v1.6.0 — Minecraft 26.2 Support New:

Full compatibility with Minecraft 26.2.

All features ported and tested: /lon tps, /lon memory, /lon report, /lon entities, /lon entities clear, /lon ping, /lon mods, /lon threads, /lon async entities, /lon autopregen, auto-GC, entity overload warnings, TPS history, object pooling, and string deduplication.

Notes:

The on-screen HUD remains removed for stability and simplicity.

Chat notification toggle and entity clear keybinding are not included in this release.

📄 v1.4.2 — Remove HUD Removed:

The on-screen HUD panel has been completely removed to eliminate client-side compatibility issues and reduce resource usage.

Notes:

All performance commands (/lon tps, /lon memory, /lon report, etc.) remain fully available.

Chat notification toggle and entity clear keybinding will not be added at this time.

📄 v1.4.0 — NeoForge Release 🎉 New Platform Support:

Lon is now available on NeoForge 26.1.2.65-beta!

All core features are fully functional:

Performance commands: /lon tps, /lon memory, /lon memory gc, /lon report, /lon help

World tools: /lon entities, /lon entities clear, /lon chunks

Utilities: /lon ping, /lon mods, /lon threads, /lon async entities

Smart auto pregen with /lon autopregen on/off (enabled by default)

Background optimizations: auto-GC, entity overload warning, TPS history recording, object pooling, string deduplication.

ℹ️ Notes:

The on-screen HUD (FPS/memory/TPS panel) is not yet available on NeoForge due to rendering API differences. Use /lon tps, /lon memory, or /lon report to monitor performance.

This build is compatible with NeoForge 26.1.2.65-beta.

📄 v1.4 — Fabric Build Fix & Cleanup Bug Fixes:

Fixed compilation error in PregenCommand.java where sendFeedback was incorrectly passing String to Component parameter.

Notes:

All core features (commands, auto-GC, smart pregen, entity warning) remain stable.

This is a maintenance release for Fabric only.

🎉 New Features:

Smart Auto Pregen: Lon now intelligently pre-generates chunks in the player's view direction as you move. Default is ON. Toggle with /lon autopregen on/off.

Network Ping: /lon ping displays your connection latency in milliseconds with color-coded feedback.

Entity Cleanup: /lon entities clear safely removes all dropped items (except XP orbs) to quickly reduce lag.

Memory Pressure Warning: HUD memory line now changes color dynamically:

🟢 Green: safe (<60%)

🟡 Yellow: warning (60-80%)

🔴 Red: high pressure (80-90%)

🔴⚡ Flashing Red: critical (>90%)

⚡ Improvements:

Entity overload warning now includes a direct suggestion to use /lon entities clear.

HUD automatically hides when the F3 debug screen is open, preventing overlap.

🔧 Technical Changes:

Auto pregen uses player's view cone (FOV 120°) to generate only visible chunks, saving CPU and memory.

Memory color logic fully client-side, zero server impact.

v1.2.0 - Multi-Core & F3 Integration

🎉 New Features:

F3 Debug Screen Integration: Lon info now appears on the F3 screen (left: mod intro, right: real-time FPS, memory, TPS, and auto-GC status).

Multi-Threaded Entity Counting: /lon async entities uses parallel streams to count entities on multiple CPU cores.

Mod List Command: /lon mods lists all loaded mods with versions for easy conflict diagnosis.

CPU Core Info: /lon threads shows the number of available processor cores.

⚡ Improvements:

HUD now refreshes at a reduced rate (1Hz) and caches strings to minimize CPU/GPU overhead.

TPS display on HUD now uses exponential smoothing to reduce flicker.

Entity warning cooldown and auto-GC cooldown now strictly 1 minute.

F3 screen integration uses a stable Mixin to DebugScreenOverlay.

🔧 Technical Changes:

All rendering now uses standard Fabric API HUD system (HudElementRegistry).

Removed all experimental Mixin classes except the stable F3 overlay.

Mod logo and metadata updated for a cleaner presentation.

📦 Size: ~55 KB (still ultra-lightweight).

Compatibility:

Minecraft 26.1.2

Fabric Loader ≥ 0.19.1

Fabric API 0.145.4+26.1.2

Java 25

The HUD automatically adapts to GUI scale and hides when the screen is hidden.

⚡ Improvements:

Smoothed TPS display to avoid flickering.

Semi-transparent background behind the HUD for better visibility.

Optimized rendering to minimize performance overhead.

🔧 Technical Changes:

Upgraded to the correct Fabric API HUD system (HudElementRegistry) for Minecraft 26.1.2.

Removed all experimental Mixin classes, keeping the mod fully based on standard Fabric API.
