v4.0.0

Improved compression efficiency

• Diced units are now dynamically sized adapting to the source content
• Individually trimming partially transparent units
• Merging units that always occur together into blocks
• Coalescing adjacent units with solid colors

The compression improvement is most noticeable for flat-color art with small dice unit sizes.
