Corel Painter 2020 in the current Humble Software Bundle + question

Humble Software Bundle: Be A Creative Superhero With Painter, CorelCAD, and CorelDRAW

Link to the bundle

Corel Painter 2020 is in the Third Tier, around €25.43 (you get what's listed under the first two tiers alongside the items listed under the Third Tier).

Question:

2019 is working well on my system, in that apart from a few minor things it pretty much does most things I want it to with no lag and no crashes. Is it still worth it to upgrade to 2020, or should someone like me just skip it? Any must-have QOL features you've liked enough to rec the upgrade?
