Thank you for a quick reply. I see your point.
Officially we promote only the latest Kotlin version, which is specified in the Kotlin header on
our web site. That’s why we have documentation only for this version.
Could you please create a feature request in
our issue tracker?
We, as the Kotlin team, can decide to maintain and support several Kotlin versions in the future and we will need documentation for different versions as well. Your request would be very helpful in this case.
However, we recommend that you update to the latest version and get most of Kotlin!
Here you can find a list of Kotlin releases.
