+# 1.9.1 (October 2025)
+
+_Changes since 1.9.0_
+
+## Migration Notes
+
+### Multiple Platforms
+
+- `compose.material3` alias from Gradle plugin now points to `org.jetbrains.compose.material3:material3:1.9.0` (based on Jetpack Compose `1.4.0`), it was `org.jetbrains.compose.material3:material3:1.8.2` (based on Jetpack Compose `1.3.2`) in Compose Multiplatform `1.9.0`. If you want to stay on the same minor version, replace the alias by an explicit dependency: [#5441](https://github.com/JetBrains/compose-multiplatform/pull/5441)
+
+  ```
+  // was
+  implementation(compose.material3)
+  
+  // replace by
+  implementation("org.jetbrains.compose.material3:material3:1.8.2")
+  ```
+
