Subject: [PATCH] Use stable Kotlin compiler frontend (#1506)

* Use stable Kotlin compiler frontend

Using K2 means library consumers must also
update, otherwise they will have errors like
"<classname> is compiled by the new Kotlin
compiler frontend and cannot be loaded by the old
compiler"

* Update changelog
