Firmware changelog

I have about 40 sonoff ELITE POW devices in Kenya running across various homes. I have noted that the devices randomly switch off while in use. As these are connected to running appliances, I have set the power-on state to ON. However all devices are running on firmware version 1.0.2. The random turn on-off issue may be related to the commands sent from the cloud as I have seen other issues mentioned, but I would also like to know whst is the firmware changes as availed in a changelog in moving from 1.0.2 to 1.0.7.

Sorry for late reply and causing such inconvenience for you.

Did all of your 40 devices turn on and off automatically at the same time? Or just a few devices that have the problem?
