This has possibly been abandoned without notification to keep drawing sales and subscriptions from patreon.
It has not been abandoned. We're just working on a major update.
We post at least semi regularly, once every 1-2 weeks on our platforms' development news.
We aren't as 'active' here, but we do update the builds when we have new content.
You can also contact us pretty much anytime on the discord, and we'll respond within a reasonable time.
Thanks.
