 1.6.0-RC / 2023-08-03
 ==================
 
 This release is based on the Kotlin 1.9.0.
 
 ### Removal of Legacy JS target
+
 Some time ago, in Kotlin 1.8, [JS IR compiler was promoted to stable and old JS compiler was deprecated](https://kotlinlang.org/docs/whatsnew18.html#stable-js-ir-compiler-backend).
 Kotlin 1.9 promotes the usage of deprecated JS compiler to an error. As a result, kotlinx.serialization no longer builds with the legacy compiler
 and does not distribute artifacts for it. You can read the migration guide for JS IR compiler [here](https://kotlinlang.org/docs/js-ir-migration.html).
