+## 1.0.0 - 2026-05-04
+### Breaking Changes
+* **`MealInDbBaseClientFacingSource` builder** — the `TimestampStage.timestamp()` method now returns `CalendarDateStage` instead of `NameStage`; existing builder chains must insert a `.calendarDate(...)` call between `.timestamp(...)` and `.name(...)`.
+### Added
+* **`MealInDbBaseClientFacingSource.getCalendarDate()`** — new required field exposing the meal date in `YYYY-MM-dd` format, sourced from the `calendar_date` JSON property.
+
 ## 0.0.1 - 2026-05-01
 * Initial SDK generation
 * 🌿 Generated with Fern
