The latest beta is pretty much there. There are only a few minor things to do now. I had wanted to get it out before Christmas, but seeing as iTunes Connect is closed for a week over Christmas, when it got to last week I realised I was never going to get it out on the MAS and in our store before Christmas, and I didn’t really fancy dealing with increased support that a release brings over the Christmas holidays. 
So, it will be out in mid-late January.
All the best,
Keith
