I've got 2 Deco XE200, and they're still waiting for their first firmware updates since launching. Currently they're on firmware 1.0.0 Build 20220722 Rel. 57229, which is the original firmware, and hardware version 1.60.  This also applies to the Archer AXE300, which is still on launch firmware V1_1.0.3 Build 20220907. 
 

I know no one can give an exact date, but since these are flagship routers, you'd expect at least one firmware update in 8 months to patch bugs and fix security flaws, but so far nothing. 
 

Professionally I've recommended these models to many clients, but it gets harder to do so when TP-Link's product page and support site don't show regular updates. 
 

Personally and professionally I love these units, but it would be nice to see more regular firmware updates. Any idea when, or if, there will be a firmware update?
