 # Rendering Changes in 9.0.0
 
-## Grid, TreeList
+## DateTimePicker
+
+* The `div.k-calendar-container` element in the popup renders a `k-datetime-container` class instead.
+* The order of the **Set** and **Cancel** buttons in the adaptive popup (`button.k-time-accept` and `button.k-time-cancel`) is reversed, so that **Set** is on the left.
+* The ButtonGroup in the popup renders a `k-button-group-solid` CSS class.
+
+## Gantt
+
+* The task delete button (`.k-task-delete`) renders as an `a` element instead of `span`.
+
+## Gantt, Grid, TreeList
 
 The `k-alt` CSS class on alternating (even) table rows is removed. Use `k-table-alt-row` instead.
 
+## Grid, TreeList
+
+* The chips in the group panel (`span.k-chip-content`) render an additional `span.k-chip-label` that wraps the text label.
+* The `table.k-grid-table` element is a direct child of `div.k-grid-content` when virtual scrolling is not used.
+* The column menu opener (`.k-grid-column-menu`) in the header cells renders as an `a` element instead of `span`.
+* The header cell in the drag column no longer renders a `k-drag-cell` CSS class.
+
+## ToggleButton
+
+The `span.k-button-icontext` element is not rendered if the Button displays only an icon.
