     5=== What's new in a nutshell ===
     6
     7The graphical user interface based on wxPython (introduced in GRASS GIS 6.4) has been enriched with many new features in order to make complex GIS operations available as simple as possible. 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.
