I didn't notice at the time, but a new @armbian release with Debian Trixie as one of the images dropped in August:

I found this out because I started poking at the #NanoPi M4 at 2am after asking my housemate for access to his media box. I started cutting back my consumption of Youtube sludge a month ago or so (using the #Unhook browser extension), and as a result might start watching some TV again after like 4 years with no TV or cinema. and the NanoPi is in the perfect spot to be a media player.
I probably won't upgrade to Trixie on it unless playback performace of HEVC demands it, I previously spent like 3 days getting the desktop set up how I like, and Armbian recommends a fresh install rather than a Debian style upgrade.
