  • v.fill.holes: New tool to remove inner isles and to keep outer boundary only
  • i.svm: New support vector machine image classification (SVM)
  • r.horizon: Output for multiple points, distances, and many other improvements
  • r.univar: Parallelization computation extended statistics
  • JSON output format support (format=”json”) in multiple tools (e.g., r.report, r.info, v.db.select, t.rast.list, etc.)
  • New grass.jupyter.SeriesMap class for animating series of vectors or rasters
  • ipyleaflet integration for grass.jupyter to create a map in ipyleaflet and add GRASS data in a single line
  • Greatly simplified the creation of new projects in Python (no more chicken and egg problems) - also in Jupyter notebooks
  • GUI: New easy command history navigation through the History browser panel browser panel
