+**Breaking changes**
+
+- Removed deprecated options for `EuiDatePicker`'s `popoverPosition` props - use `EuiPopover` values going forward
+- Removed `partition` prop from EuiCharts theme configuration - use `theme.partition` instead
+- Remove `data-grid-cell-id` attribute from `EuiDataGrid` cells - use separate `data-gridcell-column-id` & `data-gridcell-row-index` attributes instead
