# Changelog Advanced AI Spawn System

🔧 Version 4.1 — Unity 6.6 Maintenance

Minimum supported Editor: **Unity 6000.6.5f1**. Unity 6000.5 is no longer supported by 4.1.

* Updated optional AI Navigation assembly discovery to UnityEngine.Assemblies.CurrentAssemblies.GetLoadedAssemblies(), resolving UAC0005 without introducing a mandatory navigation dependency.
* Verified AI Navigation 2.0.15 detection. The validation project used official UGUI 2.6.0; no packages were changed by this maintenance fix.
* Runtime and Editor recompiled with zero product errors and warnings.
* Passed 227 navigation checks, 22 Editor checks and 629 regression assertions. Controlled samples covered Instantiate, Pooling, Automatic, Waves, Terrain/Biome, Multiple Zones and bosses, including death and pooled reuse.
* All four Custom Editors were visually checked. Configuration Undo/Redo passed; no Layout/Repaint, GUIClip or GUILayout errors were observed.
* No new features or runtime behaviour changes. Serialized fields, UnityEvents, GUIDs, public APIs and assembly identities are unchanged.

#### ⚠️ Validation scope and known demo limitation

An absent legacy NavMeshData asset remains referenced by Built-in Multiple Zones and all four URP demo scenes. Built-in Multiple Zones has separate valid modern Surface data. No demo scene or navigation data was repaired by 4.1. Full URP validation on Unity 6000.6.5f1 is pending; the retained URP variants must not be described as fully validated for this update. AI Navigation was not uninstalled from the main project during these tests.

The following 4.0 and earlier entries are historical; their older requirements do not apply to 4.1.

Version 4.0

These notes describe Advanced AI Spawn System 4.0. Earlier entries below are historical and retain the requirements of those releases.

* Unity 6000.5.5f1 minimum and official UGUI 2.5.0.
* Pooling 4.0 with Active/Retiring/Available states, repeated-death guards, component reset and corrected population accounting.
* Scaled elapsed-time timers independent of rendering frame count.
* Relative weighted prefab selection with null and zero-weight handling.
* Corrected area events and presence aggregation across manual positions and zones.
* Multiple Zones lifecycle, bounds and reference improvements.
* Terrain/Biome world-space height, validation, duplicate removal and cancellable calculation; large calculations can still be expensive.
* Boss spawning constrained by available population.
* Modern Custom Editors with stable previews, contextual validation, supported Undo/Redo and confirmed destructive actions. Automatic scene saves removed.
* Updated demo Input and AdvancedSpawnDemoCharacterController rename with retained GUID and MovedFrom.
* Demo groups/player separated from core resources.
* Additive URP 17.5.0 demo variants using official shaders; original Built-in resources retained.
* Targeted caching, performance and null-reference corrections.
* Core serialized fields, UnityEvents, GUIDs and assembly identities retained.
* Integrated AI Navigation Setup.
* Official package detection and guided installation.
* NavMeshSurface configuration and build tools.
* NavMeshLink and Modifier validation.
* Agent Type validation.
* Spawn-position validation.
* Contextual troubleshooting.
* Updated online guides for installation, lifecycle, navigation, URP and migration.
