# MotorBridge 0.4.4 Release Test Note

Date: 2026-06-04

## Summary

Hardens the `dm-device` transport: handle reuse, scan semantics, and write ACK
verification.

## Version Alignment

| Component             | Version  |
| --------------------- | -------- |
| Git release tag       | `v0.4.4` |
| Rust workspace crates | `0.4.4`  |
| Python package        | `0.4.4`  |
| C++ package metadata  | `0.4.4`  |

## Key Changes

### Fixed

* Fixed repeated open behavior for long-running `dm-device` processes by
  reusing the already-open SDK handle inside the C++ shim instead of reopening
  the same USB adapter.
