Overview of changes: This release introduces firmware support for an integrated cellular modem, delivers several fixes to door sensor and temperature monitoring, and includes quality-of-life improvements to the on-device touchscreen.

All externally relevant firmware features and specifications are identical to those in the most recently released ODIN FW version (6.0.57) other than what is called out in the release notes below.

Cellular Modem

System hardware now includes an integrated cellular modem. This firmware release adds the underlying support for cellular connectivity. This feature is not yet active. Service activation details and availability will be communicated once finalized.

On-Device Display – Network Settings Page

A new page on the touchscreen displays network settings, device information, and network status. It includes a refresh button and WebSocket connection status icons. This enables end users and field technicians to troubleshoot network issues directly from the touchscreen without needing a laptop connection.

On-Device Display – Soft Reset Button Update

Pressing the "Soft Reset" button on the touchscreen now shows an "Are You Sure?" confirmation dialog before rebooting. This prevents accidental reboots caused by incidental screen touches.

Critical bug fixes: N/A
