+# Snapmaker Orca Full Spectrum v0.9.4
+
+Mixed-filament workflow expansion, Local-Z ordering fixes, and release hardening.
+Based on Snapmaker Orca v2.2.4.
+
+## Highlights
+
+### Multi-Perimeter Mixed Filament Support
+- Added support for multi-perimeter patterns so mixed-filament layouts can preserve more complex perimeter assignments.
+- Extended the mixed-filament planning path to carry those patterns through slicing and G-code generation.
+
+### Object Color Mapping And Filament Assignment
+- Improved object-color matching with a more predictable `Keep color` path when new colors are appended.
+- Simplified appended-color handling so imported object colors map to the intended filament entries more reliably.
+- Increased the color picker capacity beyond 16 colors for larger multi-color projects.
+
+### Mixed Filament Workflow Improvements
+- Improved mixed-filament UI performance in the object-color workflow.
+- Added mixed-filament reordering support so custom entries can be reorganized without recreating them.
+- Updated project/config handling so reordered entries stay consistent across the slicing pipeline.
+
+### Local-Z And Tool Ordering
+- Added Local-Z wipe tower reserve planning and pass ordering updates to keep tool sequencing aligned with Local-Z execution.
+- Introduced `LocalZOrderOptimizer` coverage and integration points to improve pass ordering determinism.
+
+### Stability And Build Reliability
+- Added GUI startup profiling hooks to help diagnose initialization cost.
+- Hardened Bonjour socket cleanup by dropping unusable sockets more aggressively.
+- Added `/FS` to MSVC parallel compile options to reduce Windows build contention.
+
+## Tests
+
+- Added `test_local_z_order_optimizer.cpp`.
+- Expanded mixed-filament regression coverage in `test_mixed_filament.cpp`.
+- Added triangle selector coverage in `test_triangle_selector.cpp`.
+
+## Important Notes
+
+- Experimental release with limited printer validation.
+- macOS builds from this fork are unsigned and not notarized.
+- Use at your own risk.
