tippecanoe/CHANGELOG.md

1.3.0

• Tile generation is multithreaded to take advantage of multiple CPUs
• More compact data representation reduces memory usage and improves speed
• Polygon clipping uses Clipper and makes sure interior and exterior rings are distinguished by winding order
• Individual GeoJSON features can specify their own minzoom and maxzoom
• New tile-join utility can add new properties from a CSV file to an existing tileset
• Feature coalescing, line-reversing, and reordering by attribute are now options, not defaults
• Output of decode utility is now in GeoJSON format
• Tile generation with a minzoom spends less time on unused lower zoom levels
• Bare geometries without a Feature wrapper are accepted
• Default tile resolution is 4096 units at all zooms since renderers assume it

1.2.0

• Switched to top-down rendering, yielding performance improvements
• Add a dot-density gamma feature to thin out especially dense clusters
• Add support for multiple layers, making it possible to include more than one GeoJSON featurecollection in a map. #29
• Added flags that let you optionally avoid simplifying lines, restricting maximum tile sizes, and coalescing features #30
• Added check that minimum zoom level is less than maximum zoom level
• Added -v flag to check tippecanoe's version
