2.X changes from 1.X

The main incompatible change is in the artifact names. In version 1.x the jvm artifact is called kotlin-logging while in version 2.x it's called kotlin-logging-jvm to comply with the multiplatform schema. In addition, version 2.x supports only Kotlin >= 1.4.

Therefore, for jvm library owners it is still recommended to use 1.x, as for the rest of the use cases 2.x is recommended.
