# 🛡️ FPAntiFreeCam v1.4.3 — Security & Optimization Update This massive update introduces critical security hardening, prevents CPU thread/scheduler leaks on reload, and resolves several gameplay edge-cases such as vehicle mounting and spectator mode bypasses. Fully tested and verified on **PaperMC & Folia** from **1.19 up to 1.21.11 / 26.1.2**. ### 🔒 Security & Protection Hardening * **Pie-Chart Protection Overhaul:** Removed the `isPieChartProtectionEnabled` conditional guard from block entities and spawn entity packet interception. Security features (like stripping tile entity NBT data and hiding underground entity packets) are now active unconditionally while a player is in the protected zone. * **Teleport Race Condition Fixed:** Delayed state updates to align perfectly with the actual teleport tick. This eliminates a brief 1-tick window where client-side exploits could grab chest/ore data before the teleport fully registered. * **Surface Raycast Protection Fixed:** Corrected a bug where players standing fractionally below the surface Y-level had their protection inadvertently disabled. * **Mounting Protection:** Integrated `VehicleEnterEvent` and `VehicleExitEvent` monitors to instantly evaluate protection states when players enter or leave vehicles. ### ⚡ Bug Fixes & Optimizations * **Scheduler Thread Leaks Remedied:** Resolved a CPU leak during command reloads (`/fpac reload`) where repeating background tasks were not tracked and canceled. All active schedulers are now safely destroyed and re-initialized. * **Spectator Mode Bypass Support:** Fixed a layout obscuring issue where Spectators traversing protected zones were impacted by the void replacement blocks. * **Event Listener Cleanup:** Dropped redundant Bukkit event listeners to prevent internal state-racing during gamemode transitions. * **Invite Link Fix:** Fixed the expired Discord invite link in documentation. ### 🔧 Configuration * Verified compatibility across configurations. No manual file changes required!
