I'm expecting to release an update to Kotlin 1.9.22 next week, along with the scheduling module I've been working on for a while. After that's out, I'll start looking into WASM, and a PR is already up for the my Gradle convention plugins repo which should help move things along quicker. I don't think Kotest supports WASM yet, which is my biggest blocker, and there may be some other smaller libraries that might also need to be updated to fully support all of Ballasts modules.
But at the very least, I intend to disable Kotest and try to release a version with the core module on WASM quickly, and migrate the other modules more slowly as their dependencies also adopt WASM
