I said before, for me it feels like that bookerly is a tad darker with the update than before. I don't use the san serif fonts, but those have always been darker than the serif. Bookerly was always a bit lighter than caecelia and to me they feel much closer now with bookerly possibly having gotten a darker. I say possibly as it might be all in my head.
But its what I am thinking. Only fonts I use are bookerly and caecilia.
