this is probably an obvious issue but like outside of some dependency ordering thing i'm not getting or like some intermediate version being removed in the interim -- not sure of how best to investigate

This will net you 2-3 recent fairly obvious fix commits to cherry-pick :

git log --stat -Sjupyter

i can try the pickaxe -- having the logging fixes alone is a lot of changes to cherry-pick and would prefer to avoid further if possible. will look at that pr if the search is futile

You're welcome.
