That Kotlin 1.8.0 can be used in IntelliJ 2022.3 with the 1.7.21 Kotlin IntelliJ Plugin seems like a rather significant and unintuitive change. It's documented in https://kotlinlang.org/docs/whatsnew18.html, but unless I'm missing it I don't see it mentioned in https://blog.jetbrains.com/kotlin/2023/01/kotlin-1-8-0-released/. The blog post says:

For IntelliJ IDEA 2022.3, the Kotlin plugin 1.8.0 will be delivered with upcoming IntelliJ IDEA updates.

I think this might leave some waiting for that IntelliJ update before trying the Kotlin update.

Thanks for your feedback, @ianbrandt I’ve added the same info from What’s new in Kotlin 1.8.0 to the blog post.

The Kotlin/Native compiler now supports the latest stable Xcode version, 14.1.

The latest stable Xcode version is 14.2 (released 13th December).
