Second Edition Questions

Hi! New here!

I've noticed when looking at sales online, the box sets doesn't seem to have "second edition" on them. I was wondering if there was a way to tell?

I stumbled upon The Alexandrian design notes for the second edition where it's mentioned wanting to add more kitty powers. What other differences exist between first and second edition?

Since the second edition adds more powers, does that render the Power Up! supplement obsolete? Or does that offer even more kitty power?

Second Edition boxes don’t always say so clearly, but look for a 2020 copyright date. It adds streamlined rules and more kitty powers. Power Up! still adds extra powers and isn’t obsolete — just builds on what’s in 2E.

Hope that helps!
