Yes, I realize that it seems short; however, we have to draw a line
somewhere...

...especially as we've dragged our feet for so long already, and we
really intend to put out a new spec release every year or so :(

I think our aim should be to release one spec per year (ISTR that we
also put that into the charter); so *hopefully* that would be in the
first quarter/half of 2023.

For Linux/QEMU, I think we always operated under the assumption that a
commit in git is sufficient; IOW, for Linux/QEMU a new version of the
spec is not that important.

I am not sure if there are other projects out there that look only at
released versions. My impression was rather that most people were happy
enough once something seemed stable.
