Refactored asset management to use a persistent, thread-safe SQLite-backed AssetCatalog, replacing in-memory dictionaries.
Added AssetHandlerRegistry for O(1) handler lookup, ImportCoordinator for async background importing, and robust AssetMeta/AssetMetaIO for JSON-based metadata and settings.
Refactored AssetRegistry to integrate these components and support auto-import via file system watcher.
Updated IImportableAssetHandler for handler-specific settings and polymorphic serialization.
Added comprehensive unit tests for all new systems.
Removed obsolete code and legacy integration tests.
BREAKING CHANGE: Asset system APIs and storage format have changed; migration required for existing projects.
Major refactor of graphics pipeline keying, shader cache, and resource allocation.
Replaced most Allocator usage with AllocationHandle, modernized logger usage,
and unified pipeline state keys. Updated MeshUtility to use AllocationHandle.FreeList.
Added new shader pipeline architecture docs and improved error handling throughout.
BREAKING CHANGE: Pipeline keying and resource allocation APIs have changed.
Refactored ProjectBrowser to use GridView instead of ItemsView for file display, updated selection logic, and set a minimum grid height. FloatingWindow now manages DockingLayout cleanup on close to prevent resource leaks. Simplified DockDocument and DockGroup instantiations in EngineEditorWindow. Updated GetDirectoryNameConverter to use Path.GetDirectoryName directly. App shutdown now calls EditorApplication.Shutdown(). Added Ghost.Engine reference in ActivationHandler.
Refactored DockGroup to only remove obsolete TabViewItems and restore tab selection more reliably. Updated DockGroup.xaml to enable tab reordering and add-tab button. Switched to CommunityToolkit.WinUI.Controls for GridSplitter and added a style for it. Made DockPanel, DockRegionHighlight, and DockingLayout partial classes. In App.xaml.cs, wrapped initialization in a try-catch to exit on error, and ensured process exit on window close. Improved ProjectBrowser scrollbar behavior and layout settings.
Major refactor of graphics and ECS infrastructure:
- Removed IResourceManager, IRenderSystem, IFenceSynchronizer interfaces; ResourceManager and RenderSystem are now concrete classes.
- Updated all render graph, pipeline, and context code to use concrete ResourceManager.
- Refactored camera/frustum math and render extraction for clarity and correctness; frustum now uses inline arrays.
- RenderingLayerMask is now an immutable struct with bitwise operators.
- Meshlet and meshlet group data structures improved; meshlet build callback signature updated.
- Logging system overhauled: LogMessage is now a class, LogCollection supports change events, and Logger is used directly in the debug console.
- ECS query API: ChunkView.Count renamed to EntityCount; query builder/iterators use VirtualStack.Scope.
- Updated render pipeline and passes for new resource manager and render list APIs.
- Cleaned up obsolete files, improved code style, and updated documentation.
- HLSL meshlet shader updated for new struct layout.
- Debug console now uses new logger and log collection.
BREAKING CHANGE: Public APIs for resource management, rendering, ECS queries, and logging have changed. Interfaces removed; use new concrete types and updated method signatures.
- RenderGraph.Compile/Execute now return Error for better failure detection; error handling is propagated throughout compiler and executor.
- Renamed ScheduleReleaseResource to ReleaseResource for clarity; updated all usages.
- ResourceManager now calls ReleaseResource directly on Mesh, Material, and Shader types.
- Camera exposes Actual/Virtual size properties and Render returns Error.
- RenderingContext now uses IResourceManager for mesh/resource ops.
- Replaced custom BinaryWriter with BufferWriter in RenderGraphHasher.
- Improved variable naming, interface signatures, and code formatting.
- Added Error extension for IsSuccess/IsFailure.
- Minor FMOD/native interop and test code cleanups.
- No breaking API changes except for new Error return values on some methods.
