=== Overview of changes ===

'''Key improvements''' of the GRASS GIS 6.4.4 release include a complete rewrite of the r.li suite, major fixes for buffers (v.buffer, now based on GEOS library), major speedup for some vector modules (v.rast.stats and v.in.gpsbabel), various fixes for the wxPython based portable graphical interface (wxNVIZ, Location Wizard or Cartographic Composer), enabled Cairo dependency for MS-Windows, and more message translations.

Since its [http://grass.osgeo.org/announces/announce_grass640.html initial release] in September 2010 more than ''2400'' source code modifications have been made to the 6.4 release branch.
Between [wiki:Release/6.4.3-News 6.4.3] and the current 6.4.4 more than ''340'' updates have been applied.
