no it hasnt, the creator is still in the proccess of making the final chapter, she reported that its taking longer than anticipated. she posted on her patreon that maybe this month or later the update will finally be done, just have to have patients and faith.
Sept to Jan isn't a long time for an itch/adult game dev to go between updates either. If you're really only following games with more frequent updates, I'd love to know what they are because that's wild fast. haha
REC and ERICA: Knight of the Sun have pretty frequent updates. For REC, moondev has a modder or someone from the discord actively responding to players questions on itchio almost daily. Feel free to check them out, they're a great game
