golden adj.

[prob. from folklore's `golden egg'] When used to describe a magnetic medium (e.g., `golden disk', `golden tape'), describes one containing a tested, up-to-spec, ready-to-ship software version. Compare platinum-iridium. One may also "go gold", which is the act of releasing a golden version. The gold color of many CDROMs is a coincidence; this term was well established a decade before CDROM distribution become common in the mid-1990s.
