Published: 2026-11-10

This week, we got fresh RCs for Compose and Compose Material3, so we see what they include!

Also, we look at a Kotlin interpreter and the new AppState libraries. Plus, we play with a Mermaid diagram renderer and with some Google fonts.

Ooooo… What Did We Get?

Reviewing the release notes for the latest Jetpack Compose update!

The Compose alpha and beta BOMs are up to 2026.11.00. The primary Compose artifacts are now at 1.13.0-rc01, suggesting that 1.13.0 might ship in stable form before the end of 2026. Very little seems new past the last beta, other than that Modifier.border honors outline size better.

Compose Material3 is up to 1.5.0-rc01, with a few bug fixes.

Remote Compose is now at 1.0.0-alpha23, with some API cleanup to go along with bug fixes.

Wear Compose is up to 1.8.0-alpha03. You can now have ripples on your watch, change the time of TimeText(), and suppress the status bar.

Glance Adaptive reached 1.0.0-alpha04, also with some API cleanup.

Glance for Wear now sits at 1.0.0-alpha22, with yet more API cleanup, plus extended support for onTouchDown, onTouchUp, and onTouchCancel modifiers.

Nav3 for Compose shipped 1.2.1 and 1.3.0-alpha04. 1.2.1 now requires compileSdk 36 instead of 37, and the new alpha fixes a bug.

AppState StateStore is up to 1.0.0-alpha02, as is AppState Transform. Both contain minor changes.

And, we also got updates to Compose-related libraries:

• androidx.biometric:biometric-compose:1.4.0-beta01
• androidx.camera:camera-compose:1.7.0-rc02
• androidx.camera.viewfinder:viewfinder-compose:1.7.0-rc02
