The main reason for this change is that the current API for class version requirements (`KmClass.versionRequirements`) makes it impossible to support pre-1.4 metadata where this was stored incorrectly for nested classes: with the "version requirement table" in the outer class, and indexes into that table in nested classes. See KT-41011. Other than this aspect, metadata of classes is basically the same in pre-1.4 and 1.4, which means that if some kotlinx-metadata-jvm users really need to serialize metadata of an earlier version and they don't care about the version requirements issue, they can just use these new bytes but write the earlier version (e.g. 1.1) to the class file. Everything will work the same, except for the possible version requirements issue mentioned above. Note that metadata version 1.4 is still supported for `KotlinModuleMetadata.Writer` though. #KT-41011 Fixed
kotlinx-metadata
This is the platform-agnostic part of the Kotlin Metadata library, intended to provide the possibility to read and modify metadata of Kotlin declarations in the binary (.class, .js) files emitted by the Kotlin compiler. This part of the library is currently not released on its own. Please refer to kotlinx-metadata-jvm for instructions on how to load and modify Kotlin Metadata in JVM binaries (.class and .kotlin_module files).
