32125s

I looked at the old smart burn program (v1) by clicking on the smartburn word and found this:
Released Date : 2002/4/19
Revision : V1.0
Drive Models : for 32X CD-RW
LTR-32123S : firmwares after XS0U
LTR-32125W : firmwares after WBS2
LTR-32125S : all firmwares…

When was the 32125s released?

Should be a typo…
