 However, if your project or any of its dependencies depend directly on compiler artifacts such as `kotlin-compiler-embeddable` or `kotlin-annotation-processing-embeddable` then they have to be the same version as the one used by Kotlin-Compile-Testing or there will be a transitive dependency conflict.
 
 
-- Current `kotlin-compiler-embeddable` version: `1.8.21`
+- Current `kotlin-compiler-embeddable` version: `1.9.0`
 
 Because the internal APIs of the Kotlin compiler often change between versions, we can only support one `kotlin-compiler-embeddable` version at a time.
