-## Accessibility changes in v8
-
-The Data Grid v8 with row grouping feature will improve the accessibility and will be more aligned with the WAI-ARIA authoring practices.
-
-You can start using the new accessibility features by enabling `ariaV8` experimental feature flag:
-
-```tsx
-<DataGridPremium experimentalFeatures={{ ariaV8: true }} />
-```
-
-:::warning
-The value of `ariaV8` should be constant and not change during the lifetime of the Data Grid.
