# MotorBridge 0.3.9 Release Test Note

Date: 2026-05-26

MotorBridge 0.3.9 fixes RobStride unified feedback-request semantics.
RobStride does not have a private-protocol single-shot status request, and ping
replies do not synthesize `MotorState`. The unified `request_feedback()` path
for RobStride is therefore a non-blocking no-op.

Key checks:

* `request_feedback()` on RobStride does not send ping and does not block.
* `robstride_ping()` remains the explicit connectivity check.
* Fresh RobStride position/velocity values use typed parameter reads such as
  `0x7019 mechPos` and `0x701B mechVel`.
* Python, Rust workspace, and C++ package metadata are aligned to `0.3.9`.
