The Actual version numbers will not change often. I may start appending the SVN revision to the installer as I do with the zip file.
I also hope to add a win32 binary of THC-Amap and propecia.
I have compiled the SVN edition of nmap as well as the full installer with zenmap. these have been compiled against an SVN checkout of the tree on 21 October 2010.
This is version 5.35DC18. This is a large update post defcon 18.
