+### v-date-picker

+- Uses `Date` objects instead of strings. Some utility functions are included to help convert between the two, see [dates](/features/dates/).
+- `locale`, `locale-first-day-of-year`, `first-day-of-week`, `day-format`, `weekday-format`, `month-format`, `year-format`, `header-date-format`, and `title-date-format` are now part of the date adapter and use the globally configured [locale](/features/internationalization/) instead of being passed as props.
+- `active-picker` has been renamed to `view-mode`.
+- `picker-date` has been replaced with separate `month` and `year` props.
+- `range` is not currently implemented, will be added as a separate component in the future.

 ### v-form
 
 - `validate()` now returns a [`Promise<FormValidationResult>`](/api/v-form/#exposed-validate) instead of a boolean. Await the promise then check `result.valid` to determine form state.

+- Argument order for `@click:*` events is now consistently `(event, data)`.
+  - `onRowClick (item, data, event)` should be changed to `onRowClick (event, { item })`.
+- `item-class` and `item-style` have been combined into `row-props`, and `cell-props` has been added.
+- `sort-desc` and `group-desc` have been combined into `sort-by` and `group-by`. These properties now take an array of `{ key: string, order: 'asc' | 'desc' }` objects instead of strings.
