Changelogs

Version 3.2.0 highlights

  • Time Sync feature: built-in TIME_SYNC endpoint and TIME_SYNC_* packet types (enabled via timesync feature).
  • New Time Sync helpers and improved failover handling in TimeSyncTracker.
  • New Rust, C, and Python time sync examples plus additional Rust examples for relay, reliability, timeouts, and multi-node simulation.
  • RTOS time sync example code for FreeRTOS and ThreadX.
  • Updated wiki docs to surface new examples and feature behavior.
  • Full changelog: v3.1.0...v3.2.0

What's included:

  • Feature: timesync adds TIME_SYNC endpoint and TIME_SYNC_ANNOUNCE/REQUEST/RESPONSE types (built-in like TelemetryError).
  • Examples: rust-example-code/timesync_example.rs (source | mirror), rust-example-code/relay_example.rs (source | mirror), rust-example-code/reliable_example.rs (source | mirror), rust-example-code/queue_timeout_example.rs (source | mirror), rust-example-code/multinode_sim_example.rs (source | mirror), c-example-code/src/timesync_example.c (source | mirror), python-example/timesync_example.py (source | mirror), rtos-example-code/freertos_timesync.c (source | mirror), rtos-example-code/threadx_timesync.c (source | mirror).
  • C system test and examples demonstrate Time Sync announce/request/response flows.
  • Python example handles Time Sync without re-entering the router from handlers.

Version 3.1.0 highlights

  • CRC support for packets to ensure validity; in reliable mode, CRC failures trigger retransmits.
  • Fixes to the config editor GUI.
  • Full changelog: v3.0.0...v3.1.0

Version 3.0.0 highlights

  • Router side tracking is internal. Most applications should call the plain RX APIs (rx_serialized / rx) and only use side-aware variants when explicitly overriding ingress (custom relays, multi-link bridges, etc.).
  • TCP-like reliability is now available for schema types marked reliable / reliable_mode, with ACKs, retransmits, and optional ordering. Enable per side and disable when the transport is already reliable.
  • Full changelog: v2.4.0...v3.0.0

Version 2.4.0 highlights

  • Moved config to environment + JSON schema used at compile time.
  • Added a simple GUI tool for building the config.
  • Full changelog: v2.3.2...v2.4.0
