Summary by cubic

Updates SixLabors.ImageSharp from 3.1.12 to 4.1.0 to pick up .NET 8 optimizations and image decoding/encoding fixes. Behavior changes: the library now targets .NET 8 and fixes GIF transparency/dithering and PNG handling, so image outputs may differ.

  • Compatibility and migration

    • Requires .NET 8; ensure all consuming projects target net8.0.
    • GraphicsOptions.AntialiasThreshold was removed; delete any usage.
    • Pixel/color APIs were streamlined; review any direct pixel format or color space code.
    • Expect pixel-level diffs for GIF/PNG due to decoder/encoder corrections.
  • Notable improvements

    • More accurate GIF transparency and dithering; improved PNG (including Apple CgBI) and PBM validation.
    • New decoders and features: ICO/CUR/ANI support, progressive JPEG encoder.
    • Configurable MemoryAllocator limits and SIMD/alpha blending optimizations.

Written for commit d1748cf. Summary will update on new commits.
