I wouldn't look at it as a new ability or new power, but just new information that elaborates on the mechanics of Sode no Shirayuki. Her ability to lower her body temperature and having the sword extend it to her attacks is a pragmatic way of explain how does she create ice to begin with. Similar to Toshiro's Tenso Jurin is an elaboration on how he creates ice.
