Apex Network Optimizer - Update v1.5.0 (The Synergistic Engine)

This massive update introduces Synergistic Optimizations—where multiple network systems now actively communicate with each other to multiply their effectiveness. Combined with crucial Java 21 crash fixes and unlocked gigabit limits, this is our most powerful networking engine yet.

🚀 Synergistic Network Engine

• Unbounded Super Bundling: Removed the legacy 24-packet/48KB limits. The bundler now dynamically micro-batches an entire server tick into a single massive Zstd super-frame (up to 1.5MB). Because Zstd thrives on large data blocks, this exponentially increases compression efficiency.
• Compression-Aware Traffic Shaping: The backpressure system now dynamically calculates packet cost based on the server's live compression ratio. If Zstd shrinks a packet by 80%, it costs 80% fewer bandwidth tokens. Players are no longer artificially choked by uncompressed data sizes, allowing them to utilize their true wire-speed bandwidth.
• Contiguous Block RLE Deltas: Completely rewrote the Delta Codec for chunks and recipes. Instead of bloated byte-by-byte diffing, the engine now uses VarInt Run-Length Encoding (RLE) to track contiguous blocks of changes. This reduces Delta payload sizes by an additional 70% to 90%.

🛠️ Stability & Crash Fixes

• Java 21 JVM Crash Fix: Fixed an IllegalAccessError where Java 21's strict memory rules would crash the server tick when the Entity Quantizer attempted to modify final packet fields. The JVM restrictions are now safely bypassed using Mixin mutators and fail-safe fallbacks.
• Netty Infinite Loop Fix: Fixed a catastrophic pipeline bug where a player disconnecting would cause a re-entrant promise failure, resulting in an infinite "Channel closed" error loop that crippled the Netty I/O thread.
• Client Decoder Unlocked: Upgraded the client-side Bundle Decoder to safely accept the new massive Super Bundles (up to 8,192 packets per frame) without triggering false-positive corruption disconnects.

⚙️ Quality of Life & Configuration

• 10-Gigabit Network Support: Fixed a silent integer overflow in the configuration that prevented high-end servers from utilizing Gigabit/10G+ bandwidth limits. Burst buffers can now scale up to 128 MB.
• Live Server Tuning: The /apex level <1-22> command now instantly applies the new Zstd compression level in-memory without requiring a server restart, allowing admins to tune CPU load live.
• Lock-Free HUD Statistics: Completely rewrote the internal stats tracker. The HUD now reads from lock-free, zero-overhead snapshots, eliminating CPU strain on the Netty pipeline and fixing division-by-zero rendering crashes.

📈 What to Expect

• Massive Bandwidth Reductions: The combination of Super Bundling and RLE Deltas pushes data reduction to absolute extremes, heavily benefiting Starlink, cellular, and playit.gg tunnel users.
• Zero Artificial Bottlenecks: Servers with high player counts will see a much smoother experience as the traffic shaper accurately respects compressed wire-size.
• Rock-Solid Ticks: Server ticks are perfectly shielded from Java 21 memory exceptions and infinite Netty disconnect loops.
