(I really need to put more care into reading posts.)
~14h ago an update to observable’s stdlib was published that made some changes to how marked
is integrated:
Edit: One difference appears to be that the old implementation would always return a promise.
Edit 2: Looks like marked got updated from 0.3.12 to 0.6.1 in the process.
Edit 3: I believe the old behavior was due to faulty parsing, and the current behavior is the correct one. So I’m guessing that existing notebooks will have to be fixed manually.
