Another April update?

Hey all, I have a question.

So I saw an article by Droid Life about how the April patch is just rolling out to Pixel owners on AT&T. I also saw a post earlier that there was a second April update rolling out today. So out of curiosity I checked to see if there was one and there is. Mind you, I've already received my April update on day 1. I have the Pixel 7 on Verizon. Does anyone know what this second update is? What is it supposed to fix?

Thanks fam.
