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
