jetc.dev Newsletter Issue #308

Published: 2026-03-31

We got a fresh beta for Compose Multiplatform, along with the first signs of Remote Compose for Wear OS!

In addition, this week we look back on PredictiveBackHandler() and its replacement, get flexible with our boxes, and consider if text input could be rich.

And we look at yet another composition tracer. No, really.

Ooooo… What Did We Get?

Reviewing the release notes for the latest Jetpack Compose update!

JetBrains released Compose Multiplatform 1.11.0-beta01. iOS’ Z-axis handling of Dialog() and Popup() changed, and there are a bunch of bug fixes, to go along with the usual upstream changes.

Also, Google set up a new artifact group, androidx.wear.compose.remote, containing a single artifact, androidx.wear.compose.remote:remote-material3. Based on the commits, it feels like this is Remote Compose for Wear OS.
