• Fix circumcenters when the hull is collinear. #142

• Fix precision error calculating voronoi.neighbors. #138 #139
• Fix broken polygon. #140

• Update dependencies.
• Make build reproducible.

• Adopt type: module.
• Adopt delaunator@5 for robust Delaunay triangulation
• Robust Voronoi circumcenters for collinear points on the hull
• More bug fixes

This package now requires Node.js 12 or higher. For more, please read Sindre Sorhus’s FAQ.

• voronoi.cellPolygons() now gives the cell's index as property; clarify that it filters out empty polygons (#106)
• ensure ES6 (#107)

• removes a side effect (#99)

• Adds voronoi.neighbors(i)

• Mark the package as having no side effects (thanks, @stof)
• Fix the detection of degenerate (collinear) triangulations (#92)

• avoid spurious points in the corners (#88)

• Robustness of the triangulation (Delaunator 4.0.1, mapbox/delaunator#43)
• Robustness of the circumcenters: da2c24b
• Ignore more duplicate points (follow-up of #42)
