Playing it through from the start with the new patch, haven't seen new days yet but I have to say that even with the new renders as soon as it gets to day 13 the visuals (for Liza at least) upgrades noticeably, I guess it's the difference between having that tech from the base when making this scene next to just polishing.
Also I noticed a few scenes (Rachel at breakfast talking about Mrs Steele and homework for one) where briefly the picture will change in shadows a little bit (for her it's when she's looking aside thinking rather than looking at MC).
