|
## 1.4.1

|
|
|
## 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](http://www.angusj.com/delphi/clipper/documentation/Docs/_Body.htm)
|
|
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](https://github.com/mapbox/tippecanoe/pull/29)
|
|
* Added flags that let you optionally avoid simplifying lines, restricting
|
|
maximum tile sizes, and coalescing features [#30](https://github.com/mapbox/tippecanoe/pull/30)
|
|
* Added check that minimum zoom level is less than maximum zoom level
|
|
* Added `-v` flag to check tippecanoe's version
