Just updated to 1.2.70 and got this hint to migrate compiler settings to 1.3-M1 compiler. Also all Kotlin libraries are showing errors like "Class 'io.ktor.routing.RoutingKt' is compiled by a pre-release version of Kotlin and cannot be loaded by this version of the compiler". In Settings Kotlin version is set to 1.2 and I'm using Stable channel. Is it expected behavior or am I missing something?
