Three Delivery Estimate fields disappear from every API version on Oct 27
…
Until Oct 27, 2026 (midnight ET)
What changed
daily_outcomes_curve, budget_guardrail and estimate_dau are removed from Delivery Estimate responses because the service behind them was deprecated. No replacement API is available. Already gone on v26.0+, they reach all supported versions on October 27, 2026.
What to do
If a planning dashboard or forecasting tool draws expected-results curves, ask its owner whether it reads these fields and what it will show after Oct 27.
