What's new in the stable Jetpack Compose 1.12 release?
Jetpack Compose 1.12 reached stable status alongside Compose Material3 Adaptive 1.3.0, bundled in Compose BOM 2026.08.00. Key additions include a compileSdk of 37, the Styles API, rich text formatting support in BasicTextField(), and mesh gradients, as detailed by Google's Compose team. Track Jetpack Compose stable releases like this on daily.dev before planning an upgrade.
What happened to the onFocusedBoundsChanged() modifier in Jetpack Compose?
The onFocusedBoundsChanged() modifier was fully removed in Compose 1.13.0-alpha01. Developers should switch to FocusTargetModifierNode.getFocusedRect() instead to achieve the same behavior going forward. Follow Compose API removals like this on daily.dev to avoid broken builds after upgrading.
What is Compose Hot Reload's new MCP server used for?
Compose Multiplatform 1.12.0-rc01 added an MCP server tied to Compose Hot Reload, letting coding agents interact directly with a running Compose app. This enables AI assistants to inspect and act on live app state during development rather than just static code. Keep up with Compose Multiplatform tooling changes like this on daily.dev when wiring agents into your workflow.
