Yes, I'm planning a release very soon. It took a while to get publishing hooked up to the new MavenCentral system, but I do have snapshots published right now that you can try, and I've verified that I can get release builds published as well. I'm doing some internal testing on a project I'm using Ballast for, and everything's looking good. Mostly just need to document the changes before publishing a release, which I'm expecting to get to by the end of the month.
Despite not having any releases for a while, I do still use it on my own projects, and now am using it for a product I'm building a business around, so it's definitely not going anywhere. I've also been experimenting with using Ballast as the interface for a job queue, which is turning out quite promising, though it's not ready for a release yet. But I've got a PostgreSQL-backed server-side queue working quite well, and can see it working for SQS and client-side queues as well (for KMP WorkManager-like functionality).
So all that to say, I've got some exciting features coming for Ballast in the near future, and am planning on having a release targeting the latest version of Kotlin very soon. In the meantime, if you need a version now, you can try out version 4.2.2-SNAPSHOT at the new MavenCentral Snapshots maven repo (
