I know that CSS Form Builder was just released about a month ago, as I purchased it. It also included an updated Validation Toolkit extension.
Digital File Pro 2 was completely new from the DFP 1 (it contained a lot more features).
CSS Sculptor 3 maybe minor in some aspects but it did add new functions for div and spry placements and the new color picker were more than just compatibility updates.
That's what I can think of off the top of my head.
