DIVA-GIS 7 has been out for about two months. It is perhaps good to explain what's different in this version compared to previous versions. The short answer is: not that much.
Most of the changes are "behind the scenes". I have replaced pieces of the software that were hard to maintain and/or install. The good news is that DIVA-GIS installs again on all recent versions of windows (including on windows Vista and on Windows7, 64 bits); and that it will be easier to develop it further in the future.
The bad news is that because I had to rewrite a lot of code, among other things all the functions that dealt with shapefiles and/or dbf files, a lot of small bugs have crept in. Thanks to a great many of you for reporting these bugs; and keep your feedback coming.
