New toon models in MoP?

I just saw an announcement on MoP that the new character models are available. I just started here and downloaded last night 12 Mar 2017. Do I need to get a new copy to get new models? When did they go up?

Thanks a ton for what you do. Nice job. Everything is very stable and only a few quests in BloodElf starting area are bugged.

Noticed problems with the Wayward Apprentice quest I think. Never could pick up the green earth things and the final mobs were standing around. But that's minor. Don't need that to progress obviously.

Oh. Yeah. Chaotic Energy passive was dropped on my skill bar - Warlock at about level 15. Again. Very minor. No problem removing it.

Thanks for stable server and easy to get client.
