Hi everybody,
I have a question regarding Kotlin compiler plugin compatibility. Let's say, I have a plugin based on Kotlin 1.5 that uses APIs that would be removed in Kotlin 1.6 (for instance, `IdSignature.PublicSignature` was in 1.5, but is removed in 1.6).
Will my plugin (built on 1.5) work with applications using Kotlin 1.6? And vice versa, let's say I update my plugin to use Kotlin 1.6, will the clients with 1.5 be able to use the plugin version based on 1.6? How should I handle such changes?

AFAIK the compiler plugin API is currently an internal API and there are no compatibility guarantees whatsoever.
