A modern programming language that makes developers happier.

kotlinlang

The Kotlin 2.0.0 REPL says:
```Warning: REPL is not yet compatible with the Kotlin version 2.0.0, using '-language-version 1.9'.```
Can someone expand on what this implies (does it mean, for example, that the improved type inference is not available?) and when it is planned to be made fully compatible?

I also noticed that the Kotlin 2.0.0 REPL doesn't support line editing and history recall (i.e. the arrow keys); something that previous versions used to do. Is this a deliberate decision?
