-## [Unreleased]
+## [1.0.3] - 2026-06-10
 
 ### Fixed
 - `toHijriDate` and all field getters now produce exact round-trips on every host timezone (input Date interpreted by its local calendar day, matching date-fns conventions; previously used raw Date which failed in timezones west of UTC against hijri-core's UTC-day contract).
 
 ### Changed
 - `fromHijriDate` and all arithmetic/boundary helpers (`addHijriMonths`, `addHijriYears`, `startOfHijriMonth`, `endOfHijriMonth`) now return **local-midnight** Dates instead of UTC midnight / local noon. Use `getFullYear()`/`getMonth()`/`getDate()` (or date-fns `format()`) on the result — not `toISOString()`.
-- Lock-step with unreleased hijri-core `fix/utc-day-boundary` (UTC-day contract).
+- Requires hijri-core 1.0.3 (UTC-day contract).
