I am a little torn on this given there isn't a cited source and I don't know if Apple would give TC (or anyone) an exclusive on this. If it's true we're dancing in the streets though!
It shows "Feb 18, 2016" for me. Maybe something was momentarily out of sync somehow.
I'm also seeing "Last modified: Dec 21, 2015", as is the Google Cache of the page and the Web Archive. I'd assume it was published with the wrong date, and the correction hasn't fully propagated Apple's CDN/cache.
