What's so great about this release? Out of curiousity?
Others took care of the basics (OS able to do what you like with, not as impressive as it once was but still nice to have) but the bigger bonus is by virtue of being fairly mainstream on other devices you also can make it do all the weird and esoteric things you care to cook up.
If we are playing with emulators then say
https://blends.debian.org/games/tasks/emulator
I see Virtualjaguar has an arm build.
If in normal homebrew a Jaguar emulator had been made (people used to like making weird and wonderful emulators for obscure devices (
http://nintendo-ds.dcemu.co.uk/emulators-for-nintendo-ds-1158162.html http://nintendo-ds.dcemu.co.uk/emulators-for-gba-1158173.html ) but not so much these days, we'll assume it happens though) and you say had a thing that detected if it went on your home wifi that it would upload the saves/savestates to your NAS, which for reasons only worked with a funky SFTP setup. If people are allowed to tell me "cloud saves" is some crazy valuable service for Switch online then I can say having saves (and possibly ROM collections) transfer seamlessly between devices is not a crazy esoteric use case.
No way said emulator author would chain that together in their code just for you, however as it is a full OS then you can do that trivially as being a Linux based system it likely has the reference grade FTP setup if not bundled directly with the basic distro then in the default repos, to say nothing of the same code (or several versions older) likely powering your NAS as well.
So yeah it is a widely developed OS (
https://docs.armbian.com/Release_Changelog/ ), not just limited to the subset of Switch hackers that care for it* and can do something with it (probably in their free time as nobody is going to pay for it or have a company be a sugar daddy), with much functionality that you can twist to your own use cases.
*in older threads I noted the rise of IOS, and then Android when that took over from it, pretty much killed the cool PSP and DS homebrew off in short order, and then the rise of the likes of raspberry pis (there was stuff like the pogoplug and sheevaplug before it and around the same time as DS and PSP was kicking off, but they were hardly ready for prime time) with the continued existence of the former meant we did not see much of anything for the 3ds. This then means something like Linux or Android being ported being about the best chance we have for seeing a proper homebrew scene.
Oh and it likely brings a bunch of easy to use languages with it, dodges the need to have full fledged libraries built for everything (and people know enough of networking to use them) which in turn and coupled with the first thing means more people can give stuff a go -- knocking together what amounts to a sizeable chunk of a web browser to get notifications from your favourite site is hard, chaining some wget, grep, sed, awk and curl commands together in a python script is the sort of thing I expect many people would be able to learn to do.
