New Kapex 120 wings?

I see a few sites (acme tools, woodcraft etc. ) listing the Kapex 120 and 60 extension wings as “new”. But I can’t find what’s new about them. Does anyone have any info here? I’m in the market for them and am wondering if it’s worth ordering these or finding some used ones. I think even the part is the same number.
