Javascript FB.init oauth parameter for October 1st switchover

I am wondering if the OAuth parameter in the FB.init call in the Javascript SDK will start defaulting to true after the October 1st deadline. The current documentation wasn't clear on this point. Obviously you can opt-in now by using oauth: true, however if I don't need to make 开发者_开发百科changes to a whole lot of production code then I'd like to avoid it. Currently not including the parameter means OAuth is disabled.

So, it's Monday and I've seen absolutely no changes over the weekend with the facebook API in regards to Oct. 1st deadline. I'm hesitant to say that facebook was just blowing smoke? By the end of today, we may yet see something: "We will post an update on the rollout plan on Monday, Oct 3rd (the changes themselves will proceed as planned)." (from here)
