+  - New `--vaadin-grid-cell-background` style property makes it easier to style row background e.g. based on hover state: `vaadin-grid::part(row):hover { --vaadin-grid-cell-background: yellow; }`
+  - New `collapsed-row` and `collapsed-row-cell` part names in Tree Grid for styling collapsed parent rows.
+  - New `input-fields` part name in Custom Field for styling the content wrapper.
