1.6.0-beta01

Highlights

• Resource library improvements (an example project)
  • Compile-time checking of resources through a generated Res class
  • Introduce top level composeResources dir with drawable, font, files, values/strings.xml support
  • Support for various screen densities, multiple languages and regions, and light and dark themes
• Experimental support is available for tests in common code
• 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.
• iOS. Native-like caret behaviour by long/single taps in textfields(1, 2)
• Support LineHeightStyle.Trim
• Desktop. Proper clipping of SwingPanel interop (under an experimental flag, see the link)
• Popups/Dialogs can now be displayed outside the main window or panel over native components on iOS and desktop (under experimental flags, see the links)
  • iOS
  • Desktop
• Add a way to use fonts installed on the system (desktop/web in this version, iOS in the next version, Android isn't supported)

Breaking changes

• Text with lineHeight set is trimmed by default
• Text with fontSize set without lineHeight inside MaterialTheme has different line height
• 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)

Known issues

• compose.components.resources library doesn't work yet if you apply kotlin("jvm") Gradle plugin. For now, it only works with kotlin("multiplatform")
