# Change - in voxreader.to_plots(), argument "density_type" becomes "pa_type", and "pa_column" was added to allow user to choose the column representing the plant area density or index - use of prospect/fluspect properties generation included in DART has changed since DART v1264. Use cases have been adapted in consequence, keeping retro-compatibility with previous DART versions. Notes have also been added in the Prospect section of optical properties guide.
