Hello folks, has when expression always required being exhaustive for sealed classes or enums? My code use to work without the else but it seems like there's a recent change in the new Kotlin version (not stated in the changelog) that now enforces this, is that the case?

Thanks!

Note there’s a difference between when expression (=when {) and when statement (when {)
