 ## [Unreleased]
 
+### Added
+
+- Parsing: New `temporal` option in `ParseOptions`. When `true`, TOML date/time values are returned as [Temporal](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Temporal) objects (`Temporal.PlainDate`, `Temporal.PlainTime`, `Temporal.PlainDateTime`, `Temporal.ZonedDateTime`) instead of custom `Date` subclasses.
+- Stringify: Auto-detect Temporal objects in the input JS and serialize them to the correct TOML date/time type. `ZonedDateTime` IANA annotations are stripped (TOML only supports offsets).
