This includes a lot of work from our Summer of Code students as well as our regular crew of developers. The release has 10 new NSE scripts, hundreds of new IPv4 and IPv6 OS detection signatures, and a bunch of new version detection sigs bringing our total above 10,000! There are dozens of other improvements as well."
