Not sure whether they used the A model, or the longer ranged B model. The A has a range of about 230 miles, the B has a range of about 575 miles. Both are in service, and both are operational with the B-1. JASSM is a quite stealthy cruise missile, and has a terminal seeker to pinpoint targets, and transmits back to the launch platform imagery of its point of impact, to aid in damage assessment. 

This is, as best I can tell, the first time JASSM has been used in combat. JASSM is also the basis for the soon to be deployed Long Range Anti-Ship Missile, or LRASM.
