What's new in Kotlin 1.9.0

Kotlin 1.9.0 stabilizes several language features, including data objects, the ‘entries’ property for Enum classes, secondary constructors for inline value classes, and the “range until” operator. A list of classes and functions in the standard library is also marked as stable. There are a lot of changes in Kotlin/Native: a new memory allocator, fixed invocation of the deallocation hooks for Swift and Objective-C, and reworked library linkage. Also, the release comes with essential changes for Android target support in Kotlin Multiplatform.
