There's very little difference between the two versions from a documentation standpoint that I'm aware of. Version 2.47 was originally a release that Shawn did for me to correct some Sockets issues (back around 2008 if I recall correctly). I was doing a large helpdesk application that used Sockets to communicate with Kix-based service agents, and Shawn worked with me out of band to resolve those issues.
It was never published on Kixforms.org, and was quite a while before it was finally posted here - maybe a year ago or so. As it turns out, 2.47 just happened to work properly with Win-8 and up where 2.46 began to show the error above.
