From what I can tell, we told them it's ready/available but I don't know if they'll be testing it themselves or not. The plan is for them to push it to auto update at some point.

Hi everyone!
First things first - we know this has been a long time coming. You’ve all been incredibly patient in the wait for an XR700 firmware, but we’re hoping that the wait will be worth it.
That said, we’re excited to announce an Early Access firmware for the XR700 that will bring you up to scratch with DumaOS 3.3.
The latest firmware update can be found here: https://www.dropbox.com/s/zxt1dpu7i2f4hog/XR700-V1.0.1.50-0626.img?dl=0
Obviously, this is a HUGE jump from the firmware that the XR700 is currently on, with a massive deluge of new features and ways to use them. While we’re happy to answer any questions on these, here is an overview of the bigger changes:
Webview and Mobile App
Our biggest change to how you use DumaOS comes in the form of DumaOS For Mobile - a flexible view that works across any platform. For XR700 users, this can only be accessed using the DumaOS app available on both iOS and Android platforms.
AutoDPI
This improvement is less visibly obvious, but still has a huge impact on your DumaOS experience: AutoDPI massively opens up the amount of games and services that your router can detect, as well as removing the wait for new firmwares when it comes to supporting new applications.
For details on what AutoDPI is and how it improves things, check out our video on it below:
Other Additions
Of course, the leap to DumaOS 3 includes features such as Ping Heatmap, Adblocker, Connection Benchmark and more too. We have videos on using these features, with full feature tours in DumaOS itself as well.
Of course, there have been multiple fixes and improvements to DumaOS in this update as well - however, due to the sheer number of them, we have omitted their details here for the sake of brevity. 
All of us here at Netduma appreciate your support and patience in the lead up to this Early Access release. It’s worth noting that this may never come out as an official XR700 release from NETGEAR, so this may be the only way to get 3.3 on the router. We hope you enjoy everything it has to offer and get the most out of 3.3!
