This required a [http://grasswiki.osgeo.org/wiki/Convert_all_GRASS_6_vector_maps_to_GRASS_7 easy to manage topology format update] including a new spatial index. Finally, there are a series of new modules to analyse raster and vector data; some of the already existing modules were improved and made faster (some even 1000 x faster). For details see below.
