Sonoff Mini R4 firmware 1.0.1 vs 1.1.0

Yesterday only one of my several R4 showed an upgrade for the firmware from 1.0.1 to 1.1.0. I don’t know what were the changes but for sure it reduced a lot the latency time to turn on the light when a button is pushed. Can someone tell me what are the other main changes? How can I upgrade also the other R4s since this new firmware is not shown?

I have three MINIR4 devices. Two of them have shown a software update.

Tonight I was able to update everything to 1.1.0

How did you manage to upgrade the Sonoff Mini R4 firmware to 1.1.0, it didn’t work for me

Through the android app. Switch on Is much faster then before
