      SLZB-OS v3.0.9

      We’re excited to release SLZB-OS v3.0.9, bringing major improvements to Zigbee Hub, Thread, and network stability, along with performance boosts, script engine fixes, and a few critical updates.

      ⚠️ BREAKING CHANGES - ONLY FOR ZIGBEE HUB MODE USERS - NO EFFECT ON ZIGBEE2MQTT OR ZHA USERS!!!

      If you use device as Zigbee coordinator (with Zigbee2MQTT or ZHA) / Thread router - it does not affect you. Again, this change is only for those who use device in a Zigbee Hub Mode.

      • ❗ Zigbee Hub Users: All Zigbee devices must be re-paired after this update due to core changes in the Zigbee stack and API.
      • ❗ MQTT Broker Format Changed:
        • Old format: 'mqtt://example.com'
        • New format: 'example.com' (or, IP format: '127.0.0.1')

        You can now use DNS and DDNS hostnames for your MQTT broker.

      • 📘 Updated MQTT API for Zigbee Hub: View the new MQTT API documentation

      📡 Zigbee Hub Improvements

      • ✅ Redesigned Zigbee Hub network startup - now significantly faster
      • ✅ Hub now responds to Time attribute and Identify queries
      • 🐞 Fixed: Some Zigbee devices not sending reports in Hub mode
      • 🐞 Fixed: Zigbee Hub mistakenly available for EFR32 on MRx devices

      🌐 MQTT & DDNS Enhancements

      • ✅ MQTT Broker now accepts plain domain names, not only IP addresses
      • ✅ "IP Provider" setting for DDNS is now optional
      • 🐞 Fixed DDNS update interval and max value behavior
      • 🐞 Fixed excessive DNS requests from NTP client

      ⚡ Performance & System Stability

      • 🔧 Increased socket task priority for better responsiveness
      • 🔧 Moved secondary tasks on U series to PSRAM for improved memory usage
      • 🔧 Improved Thread stability for U series devices
