We did everything we could to try and release this update at some point in mid-July, but in the end, we determined more time was needed to thoroughly test and debug the next alliance raid of YoRHa: Dark Apocalypse and the new large-scale encounters of the resistance weapons content.
It's refreshing to hear statements like this from a game developer in an age where the attitude seems to have become "release it broken and patch it up later". I'm fine with waiting a little longer for that.
