My copies of volume 8 arrived. I guess these are some very small SPOILERS, but I noticed a few changes in the chapters, and I'm not really sure where else I could post this.
First of all, and as expected, in 2014-09, the chapter where Miyako calls home, Yuno now says that it's been a while since she's been at landlady's apartment, not that it's her first time there. Then Nazuna's art chapter (2014-10) has two extra pages, and now Yuno and Miyako make an appearance. Then there's one extra page in the chapter where Sae comes back (2015-01, the last chapter of the volume), and now we get an explanation how she managed to get into her old apartment in the first place.
So Asagichou has some extra work to do, and there's enough reason to reread, well, at least those chapters. You should reread the whole thing anyway!
