Neptune reference
A file, namely, with the version number 5.50.5179.1 was found in this Millennium build, but it is highly unlikely that a Neptune build with such a bizarre build number would've existed.

Some speculate that 5179.1 is, in fact, the result of a typo or a bug and that 5079.1 is the actual intended build number, which also makes more sense when put into the Neptune and Millennium timeline. Build 5079.1 would've likely been part of Milestone 1 stage. Judging by the file dates, it would have been compiled before 1999-10-12.
