donglora/mux/rust/CHANGELOG.md

Changelog

0.1.1 — 2026-04-06

Fixed

• Prevent multiple mux instances from running simultaneously via file-based exclusive lock (fd-lock); stale sockets from crashed instances are cleaned up automatically
• Clearer error message when TCP port is already in use

0.1.0 — 2026-04-06

Initial release.

Features

• USB multiplexer daemon: share one DongLoRa dongle with multiple applications
• Unix domain socket and optional TCP listeners (same COBS-framed protocol)
• RxPacket broadcast to all connected clients
• Reference-counted StartRx/StopRx across clients
• Config locking: first client sets radio config, others must match or fail
• Auto-reconnect on USB hot-plug with ping verification
• Bounded per-client send queues (256 frames) with backpressure isolation
• Smart interception: redundant commands get synthetic responses without hitting the dongle
• Graceful shutdown on SIGINT/SIGTERM with socket cleanup
• TCP_NODELAY on accepted connections for low-latency frame delivery
• CLI: --port, --socket, --tcp, --verbose options
