From which version of android is there a constant change of mac-addresses at the system level?

Question

Android

I know that in Apple, starting with iOS 8, there is a constant stem of mac-addresses in order to avoid advertising surveillance. Today I learned that Android has been applying the same practice since the 5th or 6th system.
In Google and the toaster did not manage to find information about this. We need details, at least from which version exactly)
Thank you.

Android 6.0 may cause problems for WiFi Analytics companies. According to the official Android 6.0 Changes, the MAC address of Android Phones that run Marshmallow (Android 6.0) will be randomized.
