# Rendering Changes in 24.0.0

The Kendo UI for Angular 24.0.0 release introduces rendering changes in several components.

## Grid

* The `k-column-menu` class is no longer applied to the element with the `k-grid-columnmenu-popup` class but to its first child element.
* The `k-column-menu-tabbed` class is now applied to the element with the `k-column-menu` class.
* The `k-column-list-md` class is now applied only when the Grid size is explicitly set to medium.
* The `k-separator` class is no longer used in the column menu.
* The `k-form-md` class is no longer applied to the editing form element.
* The `k-group` and `k-reset` classes are no longer applied to the grouping actions menu.

* Replaced `k-gantt-views .k-button` with `k-gantt-views .k-segmented-control-button`.
