The old !Tcl/Tk based GUI has been dropped. Relevant new features are available in the core system, among the most important the [http://grasswiki.osgeo.org/wiki/GRASS_and_Python#Python_extensions_in_GRASS_GIS new Python interface to the C library]. This new feature permits Python developers to create new modules in a simple way while at the same time creating powerful and fast modules. Furthermore, the vector library was particularly improved to make it faster and more efficient with support of [http://grasswiki.osgeo.org/wiki/Category:Massive_data_analysis huge files]. 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. |
