Hi, I just searched for the link you provided.
It is from the paragraph intended for certification candidates … and not for - future - users.
So it should read, in my opinion, that the hardware should be compatible with future versions … but I haven’t found anything, at Qubes or Nitro for example (I have contacted them and am waiting for their answer), that guarantees it.
Thank you for your response. As said before, there is a lack of clarity regarding versions other - later - than those for which the hardwares have been certified by Qubes … and that’s logical.
So my first question remains because I don’t have enough knowledge to try to adapt hardware to software.
