The format was first introduced in 1980, and has been upgraded several times since then. The most significant enhancement was the addition of embedded aperture codes in early 1991. This feature allows each file to be completely self defining, needing no other accompanying documents for processing. CIRCAD utilizes embedded aperture codes in all its Gerber output files.
