- Experimental multiplatform support of `Lifecycle` and `ViewModel`.
- The `LifecycleOwner` interface is implemented on the level of Compose Multiplatform itself, providing a `LifecycleOwner` entity for all common composables
- The `ViewModel` class can be used on any platform, but it needs a factory for platforms where the necessary type cannot be discovered by class reflection (iOS and Web)
- Experimental multiplatform support of Jetpack Navigation.
- To see the Compose Multiplatform navigation library in action, check out the [nav_cupcake project](https://github.com/MatkovIvan/nav_cupcake) which was converted from the [Navigate between screens with Compose](https://developer.android.com/codelabs/basic-android-kotlin-compose-navigation#2) Android codelab.
- [Support multi-module projects and libraries publication with Compose resources](https://github.com/JetBrains/compose-multiplatform/pull/4454) <sub>_(Kotlin `2.0.0-Beta05` or higher is required)_</sub>
## Known issues
- `inline fun <reified VM> viewModel(...)` is not available from common due to [compiler bug](https://github.com/JetBrains/compose-multiplatform/issues/3147). Please use `fun <VM> viewModel(KClass, ...)` overload instead.
- Compose Multiplatform doesn't provide default `ViewModelStoreOwner` yet. For using `ViewModel`s outside of `NavHost` you need to provide custom store owner via `LocalViewModelStoreOwner`. Due to dependencies stability, it's expected to be fixed only in `1.7.0`.
