<!channel>: for upcoming RC of Kotlin 1050 or later, you will need a mandatory upgrade of the Jackson-Kotlin module to work. In the #C0KLZSCHF channel is information about a version of 1050 in case you need a release when a new RC comes out before I issue another build to maven central. This only applies to 1050 or later, an annotation class was removed that I used to detect if a class is a KotlinClass, and now I switched to a more future-proof model. Anything compiled with 1050 or later would not work with previous builds of the module as it would not see Kotlin as Kotlin.
