Looks like a great update! Definitely how they re-worked the bezier approach! There are some innovations here which I would love to see in Adobe Illustrator as well.
I've started making a plugin to help visualise curvature continuity (using the Illustrator C++ SDK). For example: https://i.imgur.com/4dvV4pN.png
The problem I'm facing is I can't figure out how to make it update live as you drag curve control points around. Currently it only updates once you let go.. :-/
