- libjxl 0.12 release improves JPEG-XL image format performance and features.
- Includes new jxltran tool for extracting codestreams from JXLP boxes.
- Progressive lossless images are 30~40% smaller and encode 2-5x faster with multi-threading.
- Lossless images decode faster and are 30~80% smaller overall.
- SIMD optimizations boost encoding, with EstimateCost SIMDified for 5% improvement.
- Modular encoding/decoding up to 4x faster via SIMD, and histogram encoding/decoding overhauled.
