:mega: *JS IR compiler backend is Stable!* 

Starting with Kotlin 1.8.0, the <https://kotlinlang.org/docs/js-ir-compiler.html|Kotlin/JS intermediate representation (IR-based) compiler> backend is Stable. It took a while to unify infrastructure for all three backends, but they now work with the same IR for Kotlin code.

:warning: As a consequence of the stable JS IR compiler backend, the old one is deprecated from now on.

*Incremental compilation is enabled by default along with the stable JS IR compiler.*
*If you still use the old compiler, switch your project to the new backend with the help of our <https://kotlinlang.org/docs/js-ir-migration.html|migration guide>.*
