i compared the old and new levels last night, and this is what I found:
The old Adult 1 is basically split into the new Adult 1 and Adult 2. The old "forward strides and gliding" becomes two skills in Adult 1, and the old "backward skating" becomes "back 2 foot glide" and "back wiggles" in Adult 2. They add "glide and dip" to Adult 1.
Of the old Adult 2 skills, "forward stroking" stays on Adult 2. Otherwise, these skills are all on Adult 3, with the exception of "forward pivot", which is on Adult 4.
Adult 3 gets a little messy. "Beginning 2 foot spin" stays on Adult 3. "Backward edges on a circle", "backward crossovers", and "basic forward outside and forward inside consecutive edges" are on the new Adult 4. The footwork sequence goes to Adult 5, but it might be a little different - I didn't compare that closely. The inside open mohawk goes to Adult 6.
The old Adult 4 keeps forward outside 3 turns on Adult 4, but moves the inside threes to Adult 5. The new Adult 4 also retains the back chasses on a circle and adds forward outside swing rolls and back crossovers to a landing position (which also shows up on Adult 6, but specifies a back outside edge landing position). The "forward outside to inside change of edge sequence" goes to Adult 5, and the perimeter stroking and the footwork sequence go to Adult 6.
New elements on Adult 5 are forward and backward crossovers in a figure 8, t-stop, and a 1 foot spin.
New elements on Adult 6 are a lunge, a spiral, and an optional bunny hop.
