The way I see it, Hyperion just released AmigaOS 3.1.4. Cloato can release AmigaOS 3.1.5 and it doesn't really matter.
I could sell printer.device v50 and who could stop me?
...and WinUAE would still run it all...
So write your software. Choose a "publisher". Profit.
I mean at this point Microsoft could publish AmigaOS 3.2 considering how much they are embracing Linux...
