Does anyone know if Kotlin 1.3 is backwards compatible with 1.2? Got a library using Kotlin and want to know if upgrading to 1.3 will be a big deal for apps that are using 1.2

Not speaking as an expert, but typically "dot" releases (1.2 -> 1.3, as opposed to a major release 1.x -> 2.0) don't break existing contracts.

Thanks all. Few sources on kotlinlang.org suggest newer releases of Kotlin for the JVM are backwards compatible with older release, so assuming that’s the case. https://kotlinlang.org/docs/reference/evolution/kotlin-evolution.html https://kotlinlang.org/docs/reference/evolution/components-stability.html
