Align version constants with the current `KotlinVersion` by KvanTTT · Pull Request #6519 · JetBrains/kotlin

Ivan Kochurkin (KvanTTT) · 2026-07-03T13:13:29Z

I've noticed that we've been changing some constants on every LV update and some version can be aligned with the KotlinVersion.CURRENT.

It could be useful to have before merging #6097 and for future version updates.

Feel free to use only particular commits that you consider useful.

         * Since the release of 2.2.0, the ABI version is aligned with the Kotlin version.
         */
-        val CURRENT = KotlinAbiVersion(2, 4, 0)
+        val CURRENT = KotlinAbiVersion(KotlinVersion.CURRENT.major, KotlinVersion.CURRENT.minor, 0)


IDEA opens a file from a jar when I try opening a definition of KotlinVersion.CURRENT that's initialized with 2.2.21 instead of the actual local 2.4.255. But it looks like a resolving bug because I have KotlinAbiVersion.CURRENT = 2.4.0 in runtime.

It's always aligned with `KotlinVersion` (at least since Kotlin 1.6.0) according to its updating throughout git history. Simplify language-to-metadata version mapping.

Ivan Kochurkin (@KvanTTT) Have you checked if this breaks org.jetbrains.kotlin.konan.test.abi.AbiVersionTest when compiling with the bumped Kotlin version?

Yes, it looks like they are fine (I rebased the branch on the latest master and relaunched /dry-run). The thing that is not fine is Align `CURRENT` in `MetadataVersion` with the current `KotlinVersion because some third-party tests are failing: https://buildserver.labs.intellij.net/buildConfiguration/Kotlin_KotlinDev_Aggregate/993276250 I reverted this change in !fixup commit and those tests seems were fixed.
