   for the main component of the data hiearchy while maintaining backward
   compatibility.
   - 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
      - This work was funded was developed with funding from NSF Award

   - 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
