Increased range with BLE (BlueTooth 5.0) -- is it in Sprout today or in roadmap?

Hi! My first post. I am very interested in PSA products, chasing a purchase of the SG/M700 system, but also looking at Sprout for my daughter. Would really like to know what version of Bluetooth it currently ships with. 4.2? 5.0?? Unable to find in specs and when I called in, someone shared that it was 2.0 (from 2005?) Thanks, anyone!

their online pdf version of the sprout 100 manual says bluetooth 2.0
