Lightbuild release notes

Experimental: Lightbuild is an experimental preview. Its design is still evolving, and it doesn't yet support all Android build features. For production apps, existing projects, or ambitious new apps, continue using Kotlin DSL. The Lightbuild preview is best suited for small apps, prototypes, and demos. For details about what it supports, see the Kotlin DSL comparison and the release notes.

This page lists the new features and known issues in each Lightbuild release. To get started with Lightbuild, see Get started with Lightbuild. To report a bug, file an issue.
