+- The `utils` field in `PickersAdapterContextValue` has been removed in favor of the `adapter` field.
+  This should no longer affect you, as the context export has also been removed.
+- `MuiPickersAdapterContext` export has been removed.
+  Prefer using the `usePickerAdapter` hook. [Read more](https://mui.com/x/migration/migration-pickers-v8/#localizationprovider-breaking-changes).
