Eclipse Zenoh 1.8.0 (Kiyohime)

Named after the passionate serpent-dragon of Japanese legend, Kiyohime embodies this release’s spirit: focused intensity on the things that matter. While 1.8.x doesn’t reinvent the wheel, it sharpens every spoke - fixing the rough edges, closing the visibility gaps, and polishing the workflows you use every day.

Key highlights of this release include:

  • Connectivity API — real-time visibility into transports, links, and topology changes across all bindings
  • TOML configuration — cut config verbosity in half while staying fully compatible with JSON
  • Unified reply QoS — prevent data loss by tying replies to their query’s quality of service settings
  • Callback lifecycle controlwait_callbacks() guarantees your callbacks finish before cleanup proceeds
  • Zenoh-Pico key expression performance — linear-time matching with 4x improvements for common patterns
  • Zenoh-Pico Admin Space — full session introspection for embedded systems
  • Liveliness token introspection — new admin endpoint to query which tokens are alive right now
  • Reconnection reliability — fixed traffic restoration after wireless network disruptions
  • Clearer Rust compatibility — explicit Rust 1.75 support boundaries with better CMake tooling
