Overview of changes

Key improvements of this release include some new functionality (assistance for topologically unclean vector data), major speedup for some vector modules, fixes in the vector network modules, fixes for the wxPython based portable graphical interface (attribute table management, wxNVIZ, and Cartographic Composer), fixes in the location wizard for Datum transform selection and support for PROJ.4 version 4.8.0, improvements for selecting the Python version to be used, enhanced portability for MS-Windows (native support, fixes in case of missing system DLLs), and more message translations.

Over 830 new features and bug-fixes have been applied since 6.4.2.
