    Release notes

    What's Changed

    ⚠️ Due to correctness fixes, behavior across the boolean-* methods has changed. If you depended on the invalid behavior of these methods take extra care when upgrading.

    @turf/bearing

    • Fix final bearing returning values outside [-180, 180] by @JSap0914 in #3077

    @turf/bezier

    @turf/boolean-contains

    • Allow boundary points in MultiPoint containment checks by @rexxars in #3024
    • Treat an equal two-vertex line as contained by @spokodev in #3080
    • Add MultiPolygon support for non-polygon types by @rexxars in #3010
    • Speed up point, line, and MultiPolygon hot paths by @rexxars in #3099
    • Reject inner polygon whose edge crosses a concave outer polygon by @aloktomarr in #3104

    @turf/boolean-crosses

    • Make MultiPoint/LineString crossing order-independent by @spokodev in #3079
    • Return false if a line/line intersection is on an endpoint by @mfedderly in #3070

    @turf/boolean-disjoint

    • Overlapping collinear lines should return false by @cycsmail in #3097
    • Test for explicit line/line touch on a boundary point by @mfedderly in #3100
    • Performance: Delegate flattening to booleanDisjoint by @rexxars in #3103

    @turf/boolean-point-in-polygon

    • Perf improvement & Fix issue with multiple polygons when the point is on the boundary of a polygon by @Pitouli in #2821

    @turf/boolean-valid

    • Add support for GeometryCollection geometries by @ltkum in #2916
    • Allow MultiLineStrings with only a single LineString by @sharmaB01 in #2846

    @turf/boolean-within

    Internally this has been rewritten to use @turf/boolean-contains. This increases correctness, but the additional checks may have regressed performance slightly depending on inputs (it is actually faster for some inputs).

    • Require an interior point in MultiPoint-in-Polygon check by @mahirhir in #3085
    • Add MultiPolygon support, de-duplicate logic by @rexxars in #3011

    @turf/clusters-dbscan

    @turf/combine

    @turf/convex

    • Correctly include properties in the final result by @blchelle in #2972

    @turf/helpers

    • Add short forms for Units and AreaUnits by @Johse in #3063

    @turf/line-arc

    @turf/line-overlap

    @turf/polygonize

    • Fix behavior when there are duplicate coordinates in the input by @Traksewt in #3045
    • Performance: Migrate to Map/Set by @mfedderly in #3074
    • Performance: Migrate edge storage from Array to Map for performance by @mfedderly in #3081

    @turf/projection

    • Docs: Use official EPSG:3857 code instead of deprecated EPSG:900913 by @cycsmail in #3101

    @turf/transform-scale, @turf/transform-translate, @turf/transform-rotate

    ⭐️ 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)

    ⚠️ 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);
