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 and script-engine fixes.

⚠️ BREAKING CHANGES — ZIGBEE HUB MODE USERS ONLY (no effect on Zigbee2MQTT or ZHA users)

If you use the device as a Zigbee coordinator (with Zigbee2MQTT or ZHA) or as a Thread router, this does not affect you.

• 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 mqtt://example.com → new example.com (or IP 127.0.0.1). DNS and DDNS hostnames are now supported.
• Updated MQTT API for Zigbee Hub — 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 the 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.
• Enhanced EFR32x bootloader activation routine.
• Improved USB power-switch logic on U series.
• Fixed second-radio status display in the web interface header.

Berry Script Engine (zHub)

• Improved support for sendTuyaData().
• Fixed readAttr() not returning correct values.

Localization

• Updated and improved UI translations across supported languages.
