  • exactEdgeLength functions renamed to edgeLength (#639)

Fixed

  • Fix polyfill bug when vertex latitude exactly matches cell center. (#603)
  • A number of issues detected via unit tests and fuzzers were fixed. (#568, #562, #558, #559, #560, #430)

    • cellToVertexes(cell, out)
    • vertexToLatLng(vertex, out)
    • isValidVertex(vertex)

Other changes
