Netgear R7800: Anyone know when their latest firmware was released?

I just checked their site and it states that the page was Last Updated:12/31/2019 which would qualify it as "brand new", but in a strictly manner it doesn't necessarily means that this is also the date the firmware was released.

What let me doubt is this page which explains the benefits of beamforming+. That document was Last Updated:11/28/2016 but already refers to their "newest" firmware

In conclusion: Which reality is really real? ;- )

PS: Just checked the referred R6300 is now on, so seems not really the latest and the greatest.....really a smart move from netgear not to publish a release date next to the firmware images.

PPS: If someone has installed on a R7800....what is stated inside the firmware?
