v1.2.0

1 year ago

This release simply updates the underlying dithering library, but has some big changes! The release notes from the library are included below:

This is release is exciting, as it fixes some long standing nagging issues with the library. Now all images should be dithered correctly and producing the mathematically best output, especially compared to existing libraries. From a correctness standpoint, I think it is likely this library is complete (for the sRGB colorspace).

Note the dithered output of color images will be different in this release for most palettes. It will be improved, but it will be different. I do not consider this a breaking change.
