1.8.0-alpha03

Changes since 1.8.0-alpha02

Highlights

Multiple Platforms

• Compose Multiplatform codebase is fully migrated to K2. Please note that native and web klibs can be consumed only with Kotlin 2.1.0 or newer. Also, due to underlying changes in the compiler plugin, it's better to recompile libraries against the new version. Please let us know if you find any compatibility issues during this migration
• Implement multiplatform BackHandler and PredictiveBackHandler. And use them in material3 widgets and androidx-navigation library

Breaking Changes

Multiple Platforms

• IdlingResource interface was moved from commonMain to android and desktop source sets. The related experimental methods of ComposeUiTest were moved too. They are not available for Web and iOS anymore. Consider using waitUntil function as an alternative. Note: it's a breaking change only for Web and iOS, but not for Desktop and Android

iOS

• Experimental classes CupertinoScrollDecayAnimationSpec and CupertinoOverscrollEffect are removed from public API

Features

Multiple Platforms

• Update skia to m132
• Adopt a new Clipboard interface with suspend functions, which work correctly on all targets including Web. The ClipboardManager was deprecated because it was not possible to correctly implement it for Web

iOS

• Support VoiceControl on iOS
• AccessibilitySyncOptions removed. The accessibility tree is built on demand
• Calculate the order and location of semantic elements in the same way as it's done on Android
• Support UIAccessibilityContainerTypeSemanticGroup for traversal groups
• Compose works correctly with nested UIScrollViews, as well as within UIScrollViews
• Added the ability to close modal Compose view controllers (with non-scrollable content on them) with a swipe gesture

Fixes

Multiple Platforms

• Fix light source position for shadow rendering to match the Material specification and Android behavior
• Fix inconsistency between Android and Desktop in placeWithLayer scale application: offset is not scaled now (Android behavior)
• Clear the canvas before rendering each frame in tests, to avoid drawing different frames on top of each other, resulting in incorrect images being returned by captureToImage

iOS

• Performance issues when iOS screen reader is active fixed
• Fixed issues where the interactive pop gesture would stop working
• Fixes an issue where it's not possible to close the UIMenu that appears over the Compose content
• Fix touches tracking for multitouch gestures

Desktop

• Elements marked with Modifier.semantics { hideFromAccessibility() } should now be correctly hidden from a11y
• Fixed the positioning of the IME candidate popup for TextField(TextFieldState) (aka BasicTextField2)
• Fixed input of diacritics via long-press on macOS in TextField(TextFieldState) (aka BasicTextField2)
• Radio buttons and any other elements using Modifier.selectable with Role.RadioButton will have their state reported to accessibility via AccessibleValue.getCurrentAccessibleValue() and as AccessibleState.CHECKED in getAccessibleStateSet()

Web

• The BasicTextField handles browser copy/cut/paste events correctly now. Previously, they were ignored

Changes since 1.7.1

Highlights

Breaking Changes

Multiple Platforms

• Tests that relied on waitForIdle, awaitIdle or runOnIdle (whether explicit or implicit) executing delay-ed coroutines will no longer work correctly. To fix this advance the test time via mainClock manually, as needed
  For example, tests that previously did something like:

  var updateText by mutableStateOf(false)
  var text by mutableStateOf("0")
  setContent {
      LaunchedEffect(updateText) {
          if (updateText) {
              delay(1000)
              text = "1"
          }
      }
  }
  updateText = true
  waitForIdle()
  assertEquals("1", text)
  

  will need to add mainClock.advanceTimeBy(1000) after waitForIdle(), because waitForIdle no longer waits for the delay-ed coroutine to complete
• Tests that advance the test clock (via mainClock.advanceTimeBy) may see different behavior with regards to the amount and timing of recomposition, layout, drawing and effects
• runOnIdle will now execute action on the UI thread
• runOnIdle will no longer call waitForIdle after executing the action
• Advancing mainClock such that it doesn't reach the next frame, will no longer cause a recomposition

Desktop

• Deprecated/experimental Modifier.onExternalDrag has been removed - common Modifier.dragAndDropTarget API should be used instead

Features

Multiple Platforms

• Support configurable vertical text centering via LineHeightStyle.Alignment
• Support Variable Fonts In All Platforms

iOS

• Add localised string for VoiceOver accessibility support
• Support state announcements for scrollable lists in VoiceOver
• Support for accessibility gestures for left-to-right languages

Desktop

• Compose plugin for IntelliJ IDEA now supports K2 mode

Resources

• Add new API to preload and cache font and image resources on web targets: preloadFont, preloadImageBitmap, preloadImageVector

Gradle Plugin

• Support compose resources in androidLibrary target

Navigation

• Basic support a navigation by deep links
• Commonize navController.navigate(Uri) method
• Implemented non-android navController.handleDeepLink(NavDeepLinkRequest) method
• New API to configure browser navigation buttons and the address line
• Navigation via a browser address field

Fixes

Multiple Platforms

• waitForIdle, awaitIdle and runOnIdle no longer consider Compose to be non-idle when coroutines launched in a composition scope call delay. This prevents tests with an infinite loop with delay in a LaunchedEffect from hanging
• Tests that advance the test clock (via mainClock.advanceTimeBy) will now correctly (re)compose/layout/draw/effects each virtual frame as needed
• runOnIdle will now execute action on the UI thread, as Android behaves
• runOnIdle will no longer call waitForIdle after executing the action, as Android behaves
• The overhead for running an empty test has been significantly reduced

iOS

• Deprecate defaultUIKitMain()
• Fixed visibility of androidx.compose.material3.internal.formatWithSkeleton that was accidently marked as public
• Fix a bug where the accessibility tree did not reload when VoiceOver was enabled
• Fix Display Cutout Padding when rotating the device

• Fix drag-and-drop when the list of supported actions doesn't include Move
• Fix accessibility focus when using compose.swing.render.on.graphics=true
• Fix "Context menu on desktop shows incorrect items after the second showing"

Resources

1.7.0

Changes since 1.6.11

Highlights

Resources

• Compose Multiplatform resources are stored in the android assets now. This fixes Android Studio Preview and cases such as a rendering resource files in WebViews or Media Players

Navigation

• Shared Element Transitions
• Safe Args in Navigation Compose

Web

• skiko.js is redundant in case of K/Wasm Compose Multiplatform for web applications and it can be removed from index.html files to not load redundant files. skiko.js will be removed from the k/wasm distribution in the future releases. skiko.js is still needed in case of K/JS Compose Multiplatform for web apps

Breaking changes

iOS

• UIKitView and UIKitViewController in package androidx.compose.ui.interop are deprecated. New API are mentioned in deprecation message. Deprecated invocations should work fine unless custom onResize is used, it is disallowed now and will print a warning.
• Actual of expected InteropView on iOS is UIResponder now instead of UIView. It's the first common ancestor for UIViewController and UIView, both of which can be integrated using iOS interop APIs
• The app will crash by default, if CADisableMinimumFrameDurationOnPhone is not set to true in Info.plist. Use newly added ComposeUIViewControllerConfiguration.enforceStrictPlistSanityCheck to opt-out of this behavior

Desktop

• Modifier.onExternalDrag has been deprecated in favor of the new Modifier.dragAndDropTarget

Android

• Minimal supported AGP raised to 8.1.0

Resources

• Deprecate resources in compose.ui in favour of the new resource library

Features

Multiple Platforms

• The clickable modifier now responds to NumPadEnter and Spacebar, too, in addition to Enter
• LocalLifecycleOwner moved from Compose UI to lifecycle-runtime-compose so that its Compose-based helper APIs can be used outside of Compose UI

• Added accessibilityEnabled: Boolean = true argument to UIKitView and UIKitViewController
• preferredStatusBarStyle, preferredStatysBarAnimation and prefersStatusBarHidden are added to ComposeUIViewControllerDelegate to allow status bar appearance modification
• Improvements in touches processing to detect if touches were meant to be delivered to interop views, or should be processed by Compose
• New UIKitView and UIKitViewController API in package androidx.compose.ui.viewinterop. Support of onReset to reuse the interop composable emitted node and avoid excessive native views reallocations, fine-grain touches strategy control (cooperative with explicit time delay, non-cooperative where no touches are received by Compose, ignoring touches)
• Basic support for BasicTextField(TextFieldState, ...) on iOS

Desktop

• Add constructor with RenderSettings to ComposePanel. Added a class RenderSettings with val isVsyncEnabled: Boolean?. When set to true gives a hint to renderer implementation of the particular ComposePanel to reduce the latency between the input and visual changes in exchange for possible screen tearing
• Add public moveEnabled and positionPercentage setters in SplitPaneState
• Implemented Drag-and-Drop from AOSP: Modifier.dragAndDropSource and Modifier.dragAndDropTarget
• Added support for input methods (languages such as Chinese, Korean, Arabic) to BasicTextField(TextFieldState, ...)

• Add a customization for resources directories. Now it is possible to use e.g downloaded resources
• Now the gradle plugin generates resources map to find a resource by a string ID
• To avoid constant reading raw font bytes on each Font usage on non-android targets, there was added the font cache. Android has own font cache inside the platform implementation
