There are definitely new commands and functionality in there, but a lot of the functionality was present in earlier versions. The shell, at least, is not wildly different in older versions. It's been a _long_ time so I can't quickly give a point-by-point comparison, but a lot there looks familiar (and the bulk of my experience was in Workbench 1.3 and 2.1).
