PCRaster 4.3.0

PCRaster 4.3.0 is the currently maintained version.

What’s new

These are the most important changes:

  • PCRaster is available on conda-forge and can be installed using conda. Supported platforms are Linux, macOS and Windows. Supported Python versions are 3.6, 3.7 and 3.8.
  • We no longer provide support for Python 2.
  • We fixed a bug occurring when pickling PCRaster maps. Note that PCRaster maps pickled with previous versions cannot be opened with this version.
  • We fixed an incorrect return value while using a nonspatial condition in ifthen.
  • We fixed several minor inconsistencies in the multicore module.
  • We added the Python functions cellvalue_by_coordinates, cellvalue_by_index, cellvalue_by_indices and version_tuple.
  • We added a plot function to create basic plots of PCRaster maps in case the matplotlib module is installed.
  • On Windows, mapattr and legend show the menu again.
  • We fixed the incorrect rendering of directional rasters in Aguila.
  • PCRaster Modflow now supports the GHB package.
  • PCRaster Modflow BCF package received an optional flag to directly pass hcond and vcond values to Modflow.
  • Command line applications now show version numbers instead of a build date.
  • The exit value of applications only showing the usage information changed from 1 (EXIT_FAILURE) to 0 (EXIT_SUCCESS).
