We build the project up from scratch in 2007/2008 after it had been abandoned. The old domain was given up by the old owner years later, what I consider a mistake. It would have been a better idea to keep it and redirect it to the new domain, but this was not my decision. In retrospect, some things might have been done differently.
Two years ago the domain was available again and someone thought, it would be a good idea to register it in order to sell it to the new project owners.
I can't say who or why they placed a old version from archive.org there. Looks like a Content squatter to me. I don't know. At least it is doing a disservice to this Open Source project.
