    v101 v102  
    122122
    123123 * Large File Support (LFS) added
    124  * New spatial index, and spatial index kept in file: faster queries (>10x for large vectors), less memory for opening an existing vector
     124 * New topology, requires rebuilding topology with v.build(.all) when switching between GRASS 6.x and GRASS 7
     125  * New spatial index, and spatial index kept in file: faster queries (>10x for large vectors), less memory for opening an existing vector
     126  * New main topology: reduced memory and disk space requirements, generally faster processing
    125127 * Cleaning function 'break polygons' faster, less memory
    126128 * Cleaning function 'snap lines' faster and modifications are minimized: a vertex is snapped to the closest anchor vertex, not to the first anchor vertex found which might not be the closest anchor vertex.
