I just released version 0.4 of Avian, an ECS-driven physics engine for @bevy.org.
This is the biggest release yet, featuring 3x performance(!), overhauled forces and joints, voxel colliders, Bevy 0.17 support, and much more.
As always, release notes can be found here:

Today, I finally merged simulation islands for Avian!
Islands are graph-like structures where bodies are connected via contacts or joints. They are used for sleeping and waking, which is crucial for reducing CPU overhead for large scenes with many dynamic bodies.

This improves the error message when `cargo metadata` fails. We run this at the start of _every_ CLI command, to understand the structure of the workspace.
