Generally good, I think. I particularly like the change from Montserrat to Inter—Montserrat is more “elegant”, I suppose, but Inter seems better suited to the overall purpose of CC. My one reservation, though: If accessibility really is driving some of these changes (as it should!), then why in the world go for a lower-contrast grey-on white rather than black-on-white for the body of forum posts? (And, poking around the site, bloglike items as well?)
This is particularly puzzling given that (a) the forums are a text-centric part of the site, and (b) most of the CC website uses black-on-white.
