• Add a temperature check to stop the LoRa board when a maximum temperature is reached.
• The GPS log is no longer too verbose (the WARNING: parsing GGA/RMC sentence returned warnings are no longer logged).
• Remove gateway_ID field from the calibration file /tmp/calib_loraloc.json.
• gateway_ID is generated by default in the packet forwarder.
• Display configured gateway_ID in packet forwarder logs
• The existing JSON configuration is no longer erased when upgrading.
• Add a tool called configure_spf2 to help to configure the packet forwarder configuration file.
• Fix compilation warning.
• Correction on TX acknowledge feature.
• Add system time to the JSON frames sent to LNS when the GPS is not available.
• The iptables firewall is now properly configured.
• Correction of the configuration file for iBTS 923 MHz.
• Correction on the field rssi_shift.

• Add AU928 default configuration file.
• Add ping statistics to log and stat JSON frames. It is a measure of the RTT (Round Trip Time) between the gateway and the LNS server (average of last 4 values).
