Version 1.4.0-alpha05 out today! 🎉

• Added full line span support to LazyStaggeredGrid (I28252)
• Adding experimental onHover to ClickableText (I6938f)
• Introduced new experimental overloads for the runComposeUiTest function and create*ComposeRule functions that accept CoroutineContext parameters. The context will be used for the test composition and any LaunchedEffect and rememberCoroutineScope() calls in the composition. (I10614, b/265177763)
• Merges the pre/post APIs of OverscrollEffect into combined 'decorator' applyToScroll and applyToFling functions. See the updated samples in the documentation for examples of how to implement an overscroll effect with the new API shape. (I8a9c4, b/255554340)
• LineBreak and Hyphens APIs in TextStyle are graduated to stable. (Ic1e1d)
• The cursor in text fields will now continue to blink even when animations are disabled. (I95e70, b/265177763)
• Modifier.basicMarquee now animates even when animations are disabled in the system settings. (I23389, b/262298306, b/265177763)
• Fixed an issue where ModalBottomSheetLayout's HalfExpanded state was calculated incorrectly and the sheet would appear to be floating. (I8c615, b/265610459)
• Fixed a bug in ModalBottomSheetLayout where the sheet would crash when going from the hidden to a visible state in some circumstances. (Ia9265, b/265444789)
• Introduced new experimental overloads for the runComposeUiTest function and create*ComposeRule functions that accept CoroutineContext parameters. The context will be used for the test composition and any LaunchedEffect and rememberCoroutineScope() calls in the composition. (I10614, b/265177763)
• Add a new API to track 1 dimensional velocity (If5a82)
• FocusRequester is now marked as @Stable. (I580ee)
• Remove an experimental annotation from the DialogProperties constructor that takes a usePlatformDefaultWidth parameter. (Ic4048)
• Added function to calculation position and tangent at a distance on a path - with PathMeasure.getPosition() and PathMeasure.getTangent() (I3b47c)
• Removed accidentally exposed public setter on PlatformParagraphStyle. (I07f47)
• More type/nullability of inline/deprecated-hidden functions (I24f91)
• Add AnnotatedString.hasStringAnnotations to query for annotations with zero-allocations. (I94dfe, b/246960758)
• Added a new overload for TextMeasurer.measure function which takes in a String as text. (I47b2d, b/242705342)
• notifyFocusedRect methods in TextInputSession and TextInputService are not deprecated again. (I23a04, b/262648050)
No m3 updates this time around

Is it just me or does alpha05 seem to require kotlin 1.8?
I did not update my compiler version (still using 1.3.2) but hit a lot of duplicate symbols errors starting with
Duplicate class kotlin.collections.jdk8.CollectionsJDK8Kt found in modules kotlin-stdlib-1.8.0 (org.jetbrains.kotlinkotlin stdlib1.8.0) and kotlin-stdlib-jdk8-1.7.20 (org.jetbrains.kotlinkotlin stdlib jdk81.7.20)

didn't see this with previous alphas

[ephemient]

looks like you have mixed-up stdlib versions in your dependencies. Kotlin Gradle Plugin 1.8 tries to help avoid that, but the more complete solution (which works on earlier versions as well) is to use kotlin-bom

[Andy Himberger]

My project only declared that I use 1.7.20 plugin in my test project (default compose project created by android studio IDE, no stdlib versions in dependencies listed), guess this is a known issue - https://youtrack.jetbrains.com/issue/KT-55297/kotlin-stdlib-should-declare-constraints-on-kotlin-stdlib-jdk8-and-kotlin-stdlib-jdk7

[ephemient]

right, you can either

dependencies {
    implementation(platform(kotlin("bom", "1.8.0")))
}

or follow the directions at https://docs.gradle.org/current/userguide/dependency_version_alignment.html#sec:align-versions-unpublished and write

abstract class KotlinAlignmentRule : ComponentMetadataRule {
    override fun execute(ctx: ComponentMetadataContext) = with(ctx.details) {
        if (id.group == "org.jetbrains.kotlin") {
            belongsTo("org.jetbrains.kotlin:kotlin-bom:${id.version}", false)
        }
    }
}
dependencies {
    components.all<KotlinAlignmentRule>()
}

to ensure no mismatches

Just faced the same and enforcedPlatform did the trick
