0.3.0 - it knows what the target is running
A keyboard is not the same on every machine. The Meta key is Win, Cmd or Super depending on who is asking, and the useful key combinations differ too. So the device now guesses what the target runs, from the way that machine enumerates USB: Windows, macOS, Linux or Android. It shows you the guess and the raw fingerprint it read. If the guess is wrong, there is a setting to say so.
The console then follows that guess. It labels the Meta key properly, and offers combinations that only make sense on that system. On Linux that is the magic SysRq sequences REISUB and REISUO, which reboot or power off a hung machine without losing the disks, and Ctrl+Alt+F1 to F6 for virtual terminals.
Also new: a rescue image inside the device. Something small and bootable, iPXE or memtest or a DOS floppy, lives in a 4 MB flash partition and is served over the same USB drive as the card. No microSD needed, and unlike the card it can be written from the console.
One bug is gone as well. A network update could come up, work, and then be rolled back at the next reset. The image is now confirmed the moment the device can be reached and re-flashed, not after every last peripheral has started.
