What changed
Producer-side tools call this non-breaking. For a consumer it is a null dereference on an unknown future date.
Affects hyperparameters on FineTuningJob reachable from 6 operations. Nothing fails at the call; it fails wherever the value is finally used, which is usually somewhere else entirely.
no longer guaranteed present; can now be null
Who is affected

Before and after
