- Callers of `wait.ExponentialBackoffWithContext` now must pass a `ConditionWithContextFunc` to be consistent with the signature and avoid creating a duplicate context. If your condition does not need a context you can use the `ConditionFunc.WithContext()` helper to ignore the context, or use `ExponentialBackoff` directly.
