The change was a mere reorganisation of slavery and the basis of the principles of graded inequality which is the soul of Chaturvarna. To put it in a concrete form, the new law declared that a Brahmin could have a Brahmin, Kshatriya, Vaishya and a Shudra as his slave. A Kshatriya could have Kshatriya, a Vaishya and a Shudra as his slave. A Vaishya could have a Vaishya and and a Shudra as his slave. A Shudra could have a Shudra only. With all this, the law of slavery remained and all Aryans whether they were Brahmins, Kshatriyas, Vaishyas or Shudras if they become slaves were subject to it.
