Kotlin 2.2.0 introduces significant language evolution with faster compilation, cleaner cross-platform libraries, and reduced boilerplate for Android apps, server-side code, and KMP libraries.
New features in Kotlin 2.2.0 include declaring implicit dependencies in function signatures, combining 'if' and 'when' statements, omitting enum-type qualifiers in obvious scopes, and inline higher-order loops breaking or continuing the outer loop directly.
Other enhancements in Kotlin 2.2.0 involve string templates with literal dollar signs, tuning diagnostics with the -XWarning-level flag, and simplifying Java-interop by default enabling -jvm-default.
The release aims to boost developer productivity and creativity by offering a wide range of improvements, from context parameters to new APIs, catering to both experienced Kotlin developers and beginners exploring JVM development.
