  • Meshcode evaluation is now more stringent.
    • Fixed a problem where a non-existent mesh code would return an incorrect value when given as input (#45).

jpmesh 1.2.0 (2020-03-26) 2020-03-26

  • API changes to functions that take mesh_size (#35). It has been changed to a numeric value in km unit instead of the mesh size string.
