How Kotlin 2.0 Will Evolve Android Development
summary
Kotlin 2.0 introduces the K2 compiler promising up to 2× faster compilation and gives a concrete six-step Android migration path (bump Kotlin, update KSP, move Compose compiler dependency into the Kotlin repo, remove kotlin compiler extensions, update Gradle, migrate Kotlin options). Compose compiler integration removes version locks and a new strong-skip mode (default in 2.0.2) changes recomposition semantics (identical instances are skipped; use @NonSkippable or @DontMemoize to force recomposition). Other changes include AutoCloseable becoming stable, Power Assert for richer test failures, and a Gradle plugin to convert DataBinding to ViewBinding to ease KSP migration.
