:mega: *Be sure to update to Kotlin 1.8.0! Here are some of its biggest highlights:*

• New experimental functions for JVM: recursively copy or delete directory content
• Improved kotlin-reflect performance
• New -Xdebug compiler option for better debugging experience
• `kotlin-stdlib-jdk7` and `kotlin-stdlib-jdk8` merged into `kotlin-stdlib`
• Improved Objective-C/Swift interoperability
• Compatibility with Gradle 7.3

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:

&gt; 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, <@U8LBKF6AJ>
I’ve added the same info from What’s new in Kotlin 1.8.0 to the blog post.

&gt; The Kotlin/Native compiler now supports the latest stable Xcode version, 14.1.
The latest stable Xcode version is 14.2 (released 13th December).
