You can check the high level overview in the "What's new in Kotlin" section on the kotlinlang: https://kotlinlang.org/docs/whatsnew21.html#standard-library

GH release notes contains a detailed list of what was included into particular release: https://github.com/JetBrains/kotlin/releases/tag/v2.1.0 (check Libraries portion).
