Date and Time Pickers
Breaking changes
-
The default DOM structure of the field has changed Learn more.
- Before version
v8.x, the fields' DOM structure consisted of an<input />, which held the whole value for the component, but unfortunately presents a few limitations in terms of accessibility when managing multiple section values. - Starting with version
v8.x, all the field and picker components come with a new DOM structure that allows the field component to set aria attributes on individual sections, providing a far better experience with screen readers.

utilsand the date object as parameters, but only the formatted value as a string. The keys affected by this changes are:clockLabelText,openDatePickerDialogueandopenTimePickerDialogue— Learn more. -
