Limit Switch V2?

As I was responding to another post, I stumbled upon this table in R6c laying out the legal Cortex electronics that can be used.
The very first line says “Limit Switch V1 / V2”. What is Limit Switch V2? I can’t find it on the VEX catalog. Directly looking up the SKU for the Limit Switch V2 also comes up with a 404. Is it part of the Workcell or EXP line, or did VEX accidentally spoil a new product release?

V2 limit switch was released with V5 during Beta - it does not appear in current V5 starter systems.

there may be a supply issue.
