@David-TP Is this available for the BE65 Pro v 1.6 in the U.S.?
I only see version 1.1.3 on the official download page.
Edit:
Nevermind. I was able to get it downloaded and upgraded with no issues.

Is it also suitable for Germany/EU?
If I want to download I am asked to switch to German website. But there is only v1.1.7 for download.
Also the Deco app tells me that my device (v1.1.7) is up to date, no newer FW available.
Just found also following notice:
Please upgrade firmware from the local TP-Link official website of the purchase location for your TP-Link device, otherwise it will be against the warranty
This doesn't make sense to me, especially if you recommend here to upgrade to latest FW.
thanks

@David-TP I know its not part of this FW update - but as mentioned by at least one other person, the backhaul config not keeping a wired connection has started to bite me as well - I have a unit in a location that has a weak WiFi connection to the main Deco and when the ethernet is the uplink, its great (of course) but when it randomly goes to WiFi, I have issues and its incredibly frustrating. TP-Link really needs to make it better with auto-detecting, or allow us to select the option it uses.

It happens to us as well, and it really disrupts network performance. I agree that the best solution would be if TP-Link allowed us to choose backhaul mode: wired only, wireless only, or auto (wired first, fallback to wireless).
We’ve already worked directly with a senior engineer at TP-Link, and the root cause is still a bit mysterious. In my setup, I believe the RSTP running on my core router conflicts with the Decos. The trick that stabilised things (at least partially) was to insert a dumb TP-Link TP-105 switch in front of each Deco before connecting them back into the network.
With this workaround, the units stop flapping as badly. They still occasionally fall back to wireless, but rebooting the affected satellite usually brings them back onto wired. So it’s not a complete fix, just a band-aid.
Unfortunately, it’s still an ongoing issue for us — serious enough that we're now considering RMA as the product isn't fit for purpose.
