That's an excellent question
Right now, 4.0 is almost completely done. We're waiting on a final piece to be delivered from Facebook that enables the new authentication scheme they'll be requiring on October 1st. Originally, this was supposed to be delivered July 1st. Then, it got pushed back to July 20th, when it was delivered, but then they stated that an additional piece would be done until July 29th. We have everything ready on our end, so we're simply waiting till the end of the week to get the last piece (hopefully) and then we'll be releasing early next week if all goes well.
For a little longer of an explanation, feel free to see another post on the matter:
