@ -358,6 +358,8 @@ Initial release
* Significantly improved conversion performance
* Switched from using CIE2000 delta-E perceptual distance metric to Euclidean distance in CAM16-UCS space. Image quality is improved, it requires much less precomputed memory (192MB cf 4GB for the 8-pixel colour mode!) and is much faster at runtime. Win-win-win!
* Removed support for 140px conversions since these were only useful to show why this is not the right approach to DHGR
* Add support for modifying gamma correction, which is sometimes useful for tweaking results with very bright or dark source images.
* Switch default to --dither=floyd, which seems to produce the best results with --palette=ntsc
* Various internal code simplifications and cleanups
