+# FuelBoard Release Notes
+
+## Next TestFlight build
+
+### Summary
+- Added a new Data checking setting with Standard and Smart modes.
+- Clarified the behavior and background-update expectations in Settings.
+
+### What changed
+- Added a dedicated **Data checking** section in Settings.
+- Added two user-facing modes:
+  - **Standard** — Saves battery. Refreshes price data up to twice daily.
+  - **Smart** — Checks for newer data more often in the background and refreshes full prices only when an update is available.
+- Smart mode now uses a lightweight metadata probe first, then only refreshes the full dataset if newer data is available.
+- Added clear explanatory copy that background checks are best-effort and happen only when iOS allows.
+- Kept larger refresh behavior conservative rather than implying exact hourly updates.
+
+### Why
+- The previous refresh model was conservative but not very configurable.
+- The new setting makes the behavior clearer and gives users a choice between battery-friendly default behavior and a smarter background-check mode.
+- The wording is designed to be honest about iOS background limits.
+
+### Suggested TestFlight notes
+- Added new Data checking modes in Settings: Standard and Smart.
+- Smart mode now checks for newer data more intelligently in the background when iOS allows.
+- Improved settings copy to better explain data freshness behavior.
+
+### Suggested What to Test
+- Open Settings and confirm **Data checking** appears as its own section.
+- Confirm the two options read clearly and feel understandable:
+  - Standard
+  - Smart
+- Switch between Standard and Smart and confirm the selection persists.
+- Confirm the explanatory copy feels accurate and not misleading about iOS background behavior.
+
+### Implementation note
+- Standard keeps the existing cache-first refresh behavior.
+- Smart adds a lightweight probe path before deciding whether to download the full data set.
+- Background timing remains best-effort under iOS scheduling.
