You're probably thinking of the monthly security updates. They're still under 6.0.0 though, just checked on Google Developers.
Where did you get that Google was releasing 6.0.1 and 6.1.0? It's still way too early I think....
Well, considering it has only reached a limited amount of users, and it's only Android One devices, it's probably a glitch, and im not thinking much about it
