v0.8 Pre-release

EXPERIMENTAL BUILD - LIMITED TESTING
Based on Snapmaker Orca v2.2.4

v0.8 full spectrum pre-release focuses on filament mixer color accuracy and Linux AppImage packaging.

This has had limited testing on the Snapmaker U1 via the community.

What's New in v0.8

Filament Mixer Color Blending (v0.8)

• Replaced the legacy RYB blend path with FilamentMixer.
• Updated mixed-filament preview/display color computation to use FilamentMixer interpolation.
• Improved mixed-filament color consistency for generated combinations.
• Retained legacy RYB conversion helpers in code as reference.

Linux AppImage Packaging (new in v0.8)

• Added Linux release artifact: Snapmaker_Orca_Linux_V2.2.4.AppImage.
• AppImage is now the primary Linux release artifact for end users.
• Current Linux build target is x86_64.
• Current runtime baseline is glibc 2.38+.
• Snapmaker_Orca.tar remains available as an advanced/manual fallback.

Warning

• Use at your own risk.
• May produce incorrect G-code in edge cases.
• Mixed-filament behavior is still experimental in some scenarios.
• This release has had limited real-printer validation.

Features Not Yet Fully Tested

1. Linux AppImage behavior across all desktop environments/distributions.
2. Mixed-filament visual color matching across different filament brands/materials.

Known Issues

• Older Linux distributions may fail to run this AppImage due to glibc mismatch.
• Some systems may require libfuse2 for AppImage execution.
• On-screen color blend preview may not exactly match physical print results.
