hi BA@, yea, i've missed it too.
what has changed (if i understand correctly), is that the site was backed up in 1/2019, and this is a result of that back up. i guess that means that anything that happened from that month to this one is gone (but that's mostly a good thing).
other than that, i doubt you'll notice anything different at all. except for all of us being older and wiser, of course! ;)
edit: remember to browse using the "activity" tab.
