In the latest version of MVVM-light (V3 SP1) both "Dispose()" and "Dispose(bool)" methods in ViewModel class are marked

Do not use this method anymore, it will be removed in a future version. Use ICleanup.Cleanup() instead

Does this mean that IDisposable interface must not be implemented in all ViewModel classes that are derived from GalaSoft.MvvmLight.ViewModelBase (and cleanup must be overrided)?

If yes, using can't be used for view-model instances... Probably I didn't understand something... Please clarify... What are the benefits of such cleaning up?

Thanks.
