5.0.0 🎉

⭐️ Major Updates

• TurfJS now supports ES Modules (Related PR's)
• Optional parameters are now defined as an Object.

🚀 New Modules

[@turf/voronoi][voronoi]

Takes a FeatureCollection of points, and a bounding box, and returns a FeatureCollection of Voronoi polygons. (PR https://github.com/Turfjs/turf/pull/1043 - Author @stevage)

[@turf/shortest-path][shortest-path]

Returns the shortest path from start to end without colliding with any feature in obstacles (PR https://github.com/Turfjs/turf/pull/956 - Author @stebogit)

[@turf/boolean-parallel][boolean-parallel]

Boolean-Parallel returns True if each segment of line1 is parallel to the correspondent segment of line2 (PR https://github.com/Turfjs/turf/pull/941 - Author @stebogit)

[@turf/nearest-point-on-line][nearest-point-on-line]

Takes a {@link Point} and a {@link LineString} and calculates the closest Point on the (Multi)LineString. (PR https://github.com/Turfjs/turf/pull/939 - Author @stebogit)

🏅 New Features/Enhancements

• Updates [@turf/unkink-polygon][unkink-polygon] testing & added flattenEach instead of using flatten. (PR https://github.com/Turfjs/turf/pull/889)

• Add multi-geomtry support to @turf/line-split (PR https://github.com/Turfjs/turf/pull/1078)

• Improve @turf/meta lineEach method to provide properties, id and bbox (PR https://github.com/Turfjs/turf/pull/1010)

🐛 Bug Fixes

• Fixes @turf/helpers earth radius variable (PR https://github.com/Turfjs/turf/pull/1012)

• Fixes @turf/polygon-tangents bug (PR https://github.com/Turfjs/turf/pull/1058)

• Fixes @turf/line-chunk bug when the number of segments is integer (PR https://github.com/Turfjs/turf/pull/1046)

• Fixes segmentEach and segmentReduce methods in @turf/meta to ensure something is returned (PR https://github.com/Turfjs/turf/pull/968)

⚠️ Breaking Change

• Optional parameters are now defined as an Object:

Before

var from = [-75.343, 39.984];
var to = [-75.534, 39.123];
var units = 'miles';
var distance = turf.distance(from, to, units);

After

var from = [-75.343, 39.984];
var to = [-75.534, 39.123];
var options = {units: 'miles'};
var distance = turf.distance(from, to, options);
