Lightning Components: New and Changed Items in Winter '27
Winter '27 changes many base Lightning web components and Aura components, mostly for accessibility and WCAG 2.2 (larger 24px touch targets, click-to-resize datatable columns, wrapping labels at high zoom). Notable functional additions: lightning-slider gains unit, unit-position, format-number, and minimum-fraction-digits attributes; lightning-datatable rows/errors gain rowTitle and the action type gains alternativeText; lightning-button-icon gains tooltip; lightning/analyticsWaveApi adds the getReplicatedFieldsWithAdvancedProps wire adapter; the new lightning/platformNavigationItemApi module is added.
