> It should be `from collections.abc import Iterable`, latest ESR is 91.3.0 which has this fixed. We can either update to it or make a simple patch for the current version.

That's just the peak of the iceberg, there's too many errors to fix (I fixed 10 or so the other day before giving up) - better update to 91.3, or build with python 3.9.
