Whatever happened to the 5th Frontier War line?

Looking at the list of publications in development for Traveller, I just noticed that the Flashpoint: Fifth Frontier War book has disappeared from the list. What has happened to it? Hopefully it hasn't been cancelled as I was really looking forward to it. I seem to recall, there was supposed to be a complete series of books regarding the 5th FW, with maybe a grand ol' boxed set in there and everything. Has all this been scrapped or just postponed (moved to 2022)?
