MotorBridge 0.3.5 Release Test Note

Date: 2026-05-20

​
Summary

MotorBridge 0.3.5 is a patch release for ABI/thread-safety hardening, Python CLI maintainability without public entrypoint breakage, CoreController polling lifecycle cleanup, RobStride scan efficiency, strict CI alignment, and documentation/version alignment.

​
Version Alignment

ComponentVersion
Git release tag when publishedv0.3.5
Rust workspace crates0.3.5
Python package0.3.5
C++ package metadata0.3.5

​
Compatibility

  • Python binding public API remains compatible: Controller, Motor, Mode, MotorState, motorbridge.__version__, and motorbridge.get_version() are still exported.
  • Python CLI public entrypoints remain compatible: motorbridge-cli, python -m motorbridge.cli, python -m motorbridge, motorbridge.cli:main, and legacy flat run arguments.
  • C ABI symbol names and signatures remain stable. Internally, same-handle operations are serialized.
