### 🌟 What's New in Fast Chunks v1.4.0 - 🧹 **Autonomous Idle Chunk Trimmer & GC**: Added `/fastchunks trim [world|all]` and a background scanner that safely unloads idle chunks far outside player view bubbles, preventing memory bloat and reclaiming server RAM. - ⏱️ **Server Tick MSPT Overload Guard**: Automatically monitors server millisecond-per-tick (MSPT). If high tick lag occurs (MSPT > 45ms), new terrain chunk generation is smoothly paused while async prefetching continues, eliminating exploration freezes. - ⚙️ **Configurable Buffer Distances**: Added `chunk-trimmer.buffer-distance` and `interval-minutes` in `config.yml` with spawn protection guards. - 📊 **Real-time MSPT Monitoring**: `/fastchunks stats` now reports server MSPT alongside average chunk completion microsecond timings.

### Fast Chunks v1.3.0 - Autonomous Memory Governor & High-Speed Vehicles #### 🛡️ Autonomous Memory Governor - Real-time JVM heap headroom evaluation every 5s to prevent OutOfMemoryError and chunk exhaustion. - Automatic backpressure throttling when heap hits 85% threshold, shielding production servers from Elytra/Boat spam. - New admin commands: - `/fc memory` - Inspect live heap percentage, governor status, and total loaded chunks. - `/fc purge` - Instantly flush pending queues and trigger JVM garbage collection. #### 🚤 High-Velocity Vehicle Prefetch Stream - Tailored lookahead streaming (8 chunks ahead within a focused 40° conic angle) for high-velocity vehicles: - Blue ice highway boat transit (60+ m/s) - High-speed minecart rail lines - Boosted horses - Prevents players from hitting unloaded chunk barriers at extreme speeds. #### ⚙️ Concurrent Terrain Generation Throttling - Segregates async cached chunk loads from new world generation (`max-generating-in-flight: 2`). - Eliminates CPU spikes caused by exploratory flight into ungenerated territory while keeping pre-cached loading blazing fast. #### 🖥️ Interactive GUI v1.3.0 - Live Memory Governor status indicator & total chunk counts in Engine Metrics header. - Interactive **Vehicle Stream Toggle** (Slot 21). - One-click **Emergency Cache Purge Button** (Slot 25). #### 🌐 Compatibility & Performance - Full support for Spigot, Paper, Purpur, and Folia (1.20 - 1.21.4). Tested and verified on Paper 26.3 with Java 25 LTS.

### ⚡ FastChunks 1.2.0 - High-Speed Elytra Stream & TPS Protection This major update addresses the #1 problem reported by server owners: **chunk loading freezes during Elytra flight** and **world generation lag spikes under low TPS**. #### 🚀 What's New in v1.2.0: - **🪽 Elytra Highway Stream Mode**: - Automatically predicts forward movement vectors for players gliding with Elytra or riding high-speed vehicles. - Dynamically projects chunk loading lookaheads ahead of travel trajectory, completely eliminating invisible chunk walls. - **🛡️ Dynamic TPS Safety Throttle**: - Automatically protects your server from crashes and tick cascades. - If TPS drops below 18.0, generation of ungenerated chunks is temporarily suspended while existing chunks load smoothly. - **🖥️ In-Game Control Panel ( or )**: - Live metric monitoring: Async Queue Size, In-Flight Tasks, Allocated RAM, Server TPS, and Avg Chunk Completion time. - 1-Click Profile Switching: **Safe** (low-spec), **Balanced** (standard SMP), and **Aggressive** (dedicated high-performance). - Quick toggles for Elytra Stream and boundary particles. - **⚡ Modern Paper & Java 21-25 Full Compatibility**: - Fully tested on Paper 1.20 through Paper 26.3 with Adoptium Temurin Java 25.

### ⚡ Fast Chunks v1.2.0 — High-Speed Flight Stream & Memory Governor Update #### 🚀 What's New: - **🪽 Elytra & High-Speed Flight Stream:** Automatic high-velocity flight detection with 6-chunk lookahead along velocity vectors and HIGH_VELOCITY_FLIGHT priority tier. - **📍 Teleport Pre-Warm API:** Asynchronous chunk pre-warm pipeline for RTP, TPA, and warp destination loading. - **🧹 Memory Idle Governor:** Automatic prefetch ticket expiry (30s) prevents memory leaks and optimizes RAM on high-traffic servers. - **📊 Redesigned Interactive Control Panel GUI (/fastchunks):** Live engine metrics, active profile indicator, and one-click flight/particle toggles.
