Well, here's what Wiki says about it.

Skittles used to be unsuitable for vegans and vegetarians because they contain shellac and gelatin, which are both derived from animals. Recently,[when?] however, Mars appears to have begun removing gelatin from some of their products, including Skittles.[6] However, the products may still contain shellac, and the gelatin removal may not apply in all countries.

Apparently not even Wiki knows when the switched happened XD But I think I remember hearing it was during the late 90s. As far as I know, they've stopped using shellac as well and instead use an edible wax, much like what is now being more widely used on produce.
