HP-UX made it to version 7 in 1990!
Solaris 7 was 1998
FreeBSD 7 was 2008
AIX 7.1 was 2010
IRIX stopped at 6.5.30
Tru64 and Ultrix both stopped before 7

Any major Unix variants I forgot?

There's the UNIX V7 certification:
<https://unix.org/unixv7.html>

It's called V7 because it certifies that a system conforms to Issue 7 of the SVID/XPG/SUS/POSIX lineage of specifications.

In practice, it means conformance to POSIX.1-2008 plus some extensions required for SUS.

Probably the worst of all names they could have chosen.

Emacs was at version 13 (after renumbering from 1.12) already in 1985.

But Emacs is a Lisp Machine, not a Unix derivative

Na, na - as everybody knows, "Emacs is an operating system" that just happens to have an integrated editor. Google searches confirm that, and we know that Google is always right.

Yes, my point is that Emacs is of an entirely different heritage from Unix. Its lineage starts on ITS, then it was ported to the MIT Lisp Machine, then to Unix. Essentially it treats Unix as a grudging substrate; the Emacs OS is a universe of Lisp

Agreed, and well said.
