This revision provides stronger network data security protection via the below mechanisms to prevent malicious firmware from being upgraded to the UPS through communication interface ports (including RJ45).

Change logs
1.	The mechanism of firmware signing adds to the code in order to protect the UPS from malicious firmware spoofs. Based on the above, firmware upgrade via NMC is re-enabled. 
2.	Added the selection of FW Update Interfaces under the LCD Menu-Configuration. This can assist the user to decide whether or not firmware upgrades are allowed through designated communication ports.
3.	Changed TLS used for SmartConnect to MbedTLS for cybersecurity.

Note Smart-UPS Firmware Upgrade Wizard tool 
always includes the latest released firmware and helps upgrade the UPS code via serial(RS232) port; Upgrade via USB port from this tool is not recommended.
