A modern programming language that makes developers happier.

kotlinlang

In java, one can build a library with the Latest possibpe version, but targets lower versions (mostly 1.8) during compilations. So yoy tend to use late technology, but keep users of the old ones happy.

Do we have something similar for kotlin??

You have `languageVersion` and `apiVersion`

See <https://kotlinlang.org/docs/compatibility-modes.html>

It's only for JVM though. AFAIK, it's not working for native and JS. (see also <https://youtrack.jetbrains.com/issue/KT-42293/Native-provide-binary-compatibility-between-incremental-releases>)

My current strategy is to allow at least 1year to upgrade. So when Kotlin 1.8 goes out, set `languageVersion` to 1.7 so that users of 1.6 can still use it (JVM has a forward compatibility of 1)
