23 September 2026 Artifact Wave

We have a two new artifact groups, androidx.a2ui and androidx.a2ui.compose, which contain Google’s first official implementation of A2UI for Compose. There are a handful of artifacts in those groups:

• androidx.a2ui:a2ui-engine:1.0.0-alpha01
• androidx.a2ui:a2ui-model:1.0.0-alpha01
• androidx.a2ui.compose:compose-runtime:1.0.0-alpha01
• androidx.a2ui.compose:compose-ui:1.0.0-alpha01
• androidx.a2ui.compose:compose-ui-testing:1.0.0-alpha01

Also, androidx.compose.material3:material3-a2ui is a new artifact, also presumably tied to A2UI.

(FWIW, I wrote a bit about A2UI for Compose over on my Pedal Assist Coding newsletter)

There is also a new androidx.test.backup group with two artifacts:

• androidx.test.backup:backup:1.0.0-alpha01
• androidx.test.backup:backup-host:1.0.0-alpha01

Soon, there should be a androidx.transition:transition-ktx:1.7.2 artifact release. That release seems to have been incomplete, as the POM file is missing.

In addition, we got over 500 new artifact versions this wave!
