A modern programming language that makes developers happier.

kotlinlang

Hi as its mentioned in docs to test some of experimental features in kotlin 2.2.20, we can add freeCompileArgs and then test them, but i tried adding this :

```compilerOptions {
        freeCompilerArgs.add("-Xdata-flow-based-exhaustiveness")
    }```
But still not able to test data-flow-based-exhaustiveness, it still shows same old error: *Add remaining branches*
Similarly for adding language version as 2.3.0 in compilerOptions, that also does not apply:
```compilerOptions {
    languageVersion.set(org.jetbrains.kotlin.gradle.dsl.KotlinVersion.KOTLIN_2_3)
}```
How i can test them?

Hi! Do you see in IDE or during compilation?

I checked In IDE with simple kotlin file, error warnings were still there.

The IDE support for `Data-flow-based exhaustiveness checks for when expressions` was added in 2025.3 EAP.

Ok thanks. I think we can add these points as well in docs that these features are available after IDE version 2025.3  , may be something like this. Thanku
