This release contains all of the changes from 1.7.0-RC and is compatible with Kotlin 2.0.
Please note that for reasons explained in the 1.7.0-RC changelog, it may not be possible to use it with the Kotlin 1.9.x
compiler plugin. Yet, it is still fully backward compatible with previous versions.
The only difference with 1.7.0-RC is that the classDiscriminatorMode property in JsonBuilder is marked as experimental,
as it should have been when it was introduced (#2680).
