If you haven't read the changelog all that closely, know that you can now customise your enemies a little bit more now. Here are the specifications:

You may notice that a few features are reminiscent of aspects of some boss types. '3 Shots', '5 Shots' and '3 (Fast)' are all attacks used by the BS Aquamentus, and 'Block if < 4' and 'Block if < 8' are reminiscent of the L2 and L3 Gohmas. These are relics of my original plan for the Enemy Editor revisions, which was a bit larger in scope.
