4.5.0

🚀 New Modules

• @turf/clusters Takes a set of points and partition them into clusters using the k-means clustering algorithm. (PR https://github.com/Turfjs/turf/pull/787 - Author @stebogit )

• @turf/boolean-disjoint Boolean-disjoint returns (TRUE) if the intersection of the two geometries is an empty set. (PR https://github.com/Turfjs/turf/pull/805 - Author @rowanwins)

• @turf/boolean-contains Boolean-contains returns True if the second geometry is completely contained by the first geometry.

Boolean-contains returns the exact opposite result of the @turf/boolean-within. (PR https://github.com/Turfjs/turf/pull/797 - Author @rowanwins)
