Remember in early March, John Mueller hinted that the Change of Address Tool in Google Webmaster Tools would soon support subdomains? Then remember a couple weeks later, we reported that subdomain support was here? It was, but now, it is officially here.
At least that is what Gary Illyes from Google told me on Twitter. Google officially announced the new subdomain support last night on Google+ amongst other social channels saying "You can now use Change of Address in Webmaster Tools to move between subdomains, not just root domains."
But like I said, you could have done that 3 weeks ago too, but Google didn't announce it yet. When I asked Google about it, I was told because now it is official:
@rustybrick Now it's official!

Either way, it's good to get the word out.
