• Allow selecting Text in SelectionContainer by double and triple tap

Web

• Compose for Web (Wasm) artifacts are available in Maven Central _{Warning: Kotlin 1.9.21 has an issue with web target. Use Kotlin 1.9.22.}

Desktop

• Popups/Dialogs can now be displayed outside the main window or panel and over native components _{(under an experimental flag, see the link)}

Breaking changes

Common

• Resource library (compose.components.resources) changes
  • resources from *Main\resources should be moved to *Main\composeResources\drawable, commonMain\composeResources\font or *Main\composeResources\files depending on the resource type
  • painterResource("resource.xml") should be replaced by painterResource(Res.drawable.resource)
• google() maven repository is now required. Add this to build.gradle.kts:

  repositories {
      ...
      google()
  }
  

  If the project doesn't have it, there will be an error Could not find androidx.annotation:annotation:... or Could not find org.jetbrains.compose.collection-internal:collection.
• Text with lineHeight set is trimmed by default
• Text with fontSize set without lineHeight inside MaterialTheme has different line height

iOS/Desktop/Web

• Deprecate public ComposeScene in favour of @InternalComposeUiApi MultiLayerComposeScene
• Hide deprecated DropdownMenu overloads

Desktop

• Remove deprecated APIs in TooltipArea and PointerEvent

Web (k/js)

• Libraries which depend on earlier Compose Multiplatform version are not compatible with 1.6.0 anymore. This is because decoys generation was disabled. Projects which apply Compose Compiler plugin manually need to remove this argument: plugin:androidx.compose.compiler.plugins.kotlin:generateDecoys=true.
