Comment 16 for bug 1931737

Sorry if I wasn't clear in comment 11 about the backporting need, Jason.

I suspect it would be safest to create a version-specific upgrade script for both 3.8 and 3.7, with a new number for each, and I'm happy to assist.

The change to an existing function is just a 1-line addition, but it's a function that has changed from 3.7 to 3.8, so it needs to be specialized. A 3.8 upgrade for that function /also/ has to be run when going from 3.7 to 3.8, though, because of unrelated changes. so we may need to add different numbered script to rel_3_7 and rel_3_8, the latter basically being a copy of just the metabib.reingest_metabib_field_entries() function from 1298.
