It looks like the version matrix at https://plugins.jetbrains.com/docs/intellij/using-kotlin.html has not been updated for 2025.3 yet - what are the correct versions we should be using?
2.2.20, as far as I can tell: intellij-community/lib/MODULE.bazel at ef8b4c6fbb2bfc5d9861dadbd677f2797714b07c · JetBrains/intellij-community · GitHub
At least for 2025.2, the matrix doesn’t match the version listed on the 3rd-party libraries page (2.2.20). I’m using the versions listed on the 3rd-party page.
We now have 2.2.20 and the final version will be known on the Beta stage
