They've more or less been saying that the update should be dropping in about a month or so since last August, so it should be ready in another month or so. 
If it's not out next month, just read this message again and it'll pretty much give you the same development update we keep getting in Discord. 

Great world building, fun characters, interesting story.
And in the full version you get all that and some hot h scenes.
10/10

As best as anyone can tell the dev just disappeared. Before the original Discord channel went down the mods mentioned that he'd sounded really excited about the new update that was almost ready and then nothing. Nobody has heard from him since.
