# 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.
