Not a lot that looks different from the UA, at first glance. One brand new element did jump out at me. The addition to the 6th level feature where once per Long Rest you can swap out a Replicated item for another plan not currently in use. That's a big upgrade, and means having a few plans with a narrow utility function is actually worth while. Instead of needing to know at the start of the day what you need, you have the ability to adjust in the field.
ETA: If there are going to be more substantial changes from the UA draft, I expect them in the subclasses. Looking forward to seeing more on that.
