Key additions include Mesh Gradients and Wide Color Gamut (P3/HDR) rendering support, named areas in the experimental Grid layout, native Credential Manager integration for text fields via a new semantics property, rich-text formatting APIs for BasicTextField, programmatic text selection control, and DeferredTransition APIs for gesture-driven animations. Modifier.onFirstVisible() is deprecated in favor of Modifier.onVisibilityChanged(). SideEffect now supports key arguments for faster one-shot effects, and new test APIs (hasPendingWork, runWithoutImplicitWait) reduce flakiness in animation testing. Startup performance has also improved, with Time to Initial Display now comparable to Views. ## Full article daily.dev links to this article rather than hosting it.

Jetpack Compose 1.12, shipped in the August '26 stable release, adds Mesh Gradients and Wide Color Gamut (P3) and HDR rendering support, named areas in the experimental Grid layout, native Credential Manager integration for text fields, rich-text formatting APIs in BasicTextField, programmatic text selection via SelectionState, and DeferredTransition APIs for gesture-driven animations like predictive back. _Track new Compose releases like this one as they ship on daily.dev._ ### How do I migrate off Modifier.onFirstVisible() in Jetpack Compose? Modifier.onFirstVisible() is deprecated in Compose 1.12; migrate to Modifier.onVisibilityChanged(), which provides more precise visibility threshold tracking for detecting when composables become visible on screen. The replacement is the recommended path going forward for view-visibility detection in Compose layouts. _Developers cleaning up deprecated Compose APIs can follow migration changes like this on daily.dev._ ### How much faster is SideEffect compared to LaunchedEffect in Jetpack Compose? SideEffect is up to 90% faster than LaunchedEffect and about 20% faster than DisposableEffect when you don't need a coroutine or dispose block. In Compose 1.12, SideEffect gained support for key arguments, letting it fire one-shot effects whenever specific keys change, though it runs before DisposableEffect and LaunchedEffect so migrating existing effects needs care. _Compare Compose effect APIs and their trade-offs as they evolve, tracked on daily.dev._ ## Similar posts on daily.dev - [What's new in the Jetpack Compose December '25 release](https://daily.dev/posts/what-s-new-in-the-jetpack-compose-december-25-release-tosr73rob) · Android Developers Blog · 7 upvotes · 0 comments - [What's new in the Jetpack Compose April '26 release](https://daily.dev/posts/what-s-new-in-the-jetpack-compose-april-26-release-dsjkgpbni) · Android Developers Blog · 1 upvotes · 0 comments --- Tags: [#testing](https://daily.dev/tags/testing), [#android](https://daily.dev/tags/android), [#kotlin](https://daily.dev/tags/kotlin), [#jetpack-compose](https://daily.dev/tags/jetpack-compose) [View this post on daily.dev](https://daily.dev/posts/what-s-new-in-the-jetpack-compose-august-26-release-0dszwic3y)
