Still S-sized S1–S6, so reach and wheelbase pick the size rather than your inseam. Check the year's travel and shock spec on the model page — Specialized has moved both since the 2021 redesign.
Trail riders who want one Specialized and are willing to size by reach. XC racers should look at Epic; the longest-travel Specialized is Enduro.
