Hello! I have found in the documentation, some statements, like:

Keep your library up-to-date. If you’re a library author, updating to the new Kotlin version is extremely important. Using older versions could block your users from updating Kotlin in their projects.

and

Change the versions of dependencies to EAP ones. The EAP version of Kotlin may not work with the libraries of the previously released version.

Does it mean that some Kotlin versions are not compatible or not ABI stable? Thanks

https://youtrack.jetbrains.com/issue/KT-42293 ABI stability of K/N output is not guaranteed, but has been experimentally compatible for some time

Thank you for the reply, for non-native is the same?

no. JVM is guaranteed to be backwards compatible: https://kotlinlang.org/docs/kotlin-evolution.html#evolving-the-binary-format

Thank you for the reply, but if non-native is backward compatible, I couldn’t get why this statement is in the documentation:

Keep your library up-to-date. If you’re a library author, updating to the new Kotlin version is extremely important. Using older versions could block your users from updating Kotlin in their projects.

looks like that text was added recently, I'm not sure why though https://github.com/JetBrains/kotlin-web-site/pull/3243
