What This Article Covers
Developers had to work with three separate @Preview annotations spread across different packages. This made it hard to figure out which annotation, platform, and IDE combination actually worked for previews.
JetBrains consolidated everything into a single @Preview annotation from androidx.compose.ui.tooling.preview.Preview. It works in the commonMain source set, and the IDE includes quick-fix suggestions that automate the migration.
The old @Preview annotations are now deprecated. This simplifies the preview workflow and makes it easier for developers to work across multiple Compose Multiplatform targets.
