JS IR backend in Beta 🥳

The IR-based backend for the Kotlin/JS compiler has been in Alpha since Kotlin 1.4.0. We never stopped working on it, and in 1.5.30 it will become Beta. This means that we don’t expect breaking changes anymore and its future development will be mainly focused on stabilization.
