how about deco m5 v3? what's the difference?

Where can i find that v1.4? I couldn't find it in firmware under deco M5 v1, v2 and v3 @Kevin_Z

I got my 2nd replacement of deco e4 3pack, due to random disconnection -It's a random disconnection from internet connected to deco wifi using just 1 pack, 2 pack or 3 packs configuration.. all...
