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
