Just wondering if you can mix a deco m5 v1 with a v2 or v3? I only have a v1 and i need to purchase another deco m5 to increase the wifi range in my house

I have a M5(1.0) deco and currently running 1.5.3 Build 20210203 Rel. 68223. When is the next firmware update meant to be released or is this product coming to EOL for ongoing firmware updates?

Background: Some of you may have updated your Apple devices to the latest iOS 14 version and get a “Weak Security” warning message when connecting to the Deco network. Why Deco network is displayed as
